  • from what ive read before. time travel is essentially sending an object, whether it be a satellite, a human being, or piece of fruit at the speed of light or greater. only problem with that is whenever you send matter through like that it wont work without and equal amount of dark matter...im kinda curious to see people unravel those theories

  • @TheSunnycar teleportation is too a word

  • This just completely blows the mind. It's amazing.

  • So if figure out a way to move myself as fast as light I can really go back in time? How would one know this would work unless someone had done it?

  • Comment removed

  • made easy? how is this easy??

  • i still dont get it!

  • Why do people refuse to accept relativety? Every once in a while you see a comment claiming that time dilation and relativity are wrong after it's proven.

    Why doesn't everyone accept it?!?!

  • Merkabah moves within an all-embracing energy field which is composed of multiple magnetic, electromagnetic, and magneto-hydrodynamic domains unified into a “field stasis” using multiple polar denominations. This gives the vehicle operating within the field the ability to go faster than the speed of our common light. that travel at 2.9 times (or more) the speed of light as defined by man. The vehicle has the ability enters the energy portal. time tunnels or “wormholes :)o*o

  • Cool;]

  • i didint understand what he ment with travel to the "space" direction

  • @Exoddusss traveling in the space direction means to travel IN space- for example, if you get in a rocket that can go the speed of light, or somewhere close to it, and you fly it for half an hour away from Earth (traveling in space) and then come back. While your watch will say you've been gone for an hour, on Earth (Which stays in more or less the same location in space, compared to how far light can travel) you may see that it's been several years or even decades since you left.

  • @LiaB03 yes thank you, but i figured it out a while ago :) but thanks anyway for the help.

  • come on now why do we talk about...going faster then speed of light . yet we can't we go 5 percent of the speed of light...let's go try 5 percent of the speed of light then 10. then 15 so on and once we get to speed of light (which will probably takes us millions of years from now) then we should talk about going faster then speed of light, does it make sence???????????????

  • Yes this theory works provided that the speed is constant.

  • This was a pretty interesting video. Now that I'm not merely a virile earthquake-generating superhero, but a time-traveling virile earthquake-generating superhero, I've been trying to learn more about physics and science and stuff just so I can get out of this time vortex that I'm in. Thanks to this, I think I understand it a bit better.

    Plus, those were awesome spaceships! I wish I had a space-ship...

  • so does this mean that if i was traveling faster thanlight, An hour for me would be like days if not more to someone who was'nt? This is cool :) 

  • @2:39:

    Where is your light-cone?? Your claims are incorrect! The material particle/object cannot accelerate to (or beyond) the surface of the light-cone, with apex at its starting point in spacetime.

  • i still dont understand

  • well doc brown managed time travel at 88mph lol

  • @Grahdx No it was 86mph.

  • @blarson12 no im posotive it was 88mph mate

  • @Grahdx I'm sure it was 86 because the movie came out in 1986.

  • If we have to go faster than the speed of light to travel through time, then we will never do it.

    There may be another way.

    George Vreeland Hill

  • Some Christians believe this is what will make the rapture possible.Many times Jesus said,"I am the light"-

  • @shotsxxx As psychiatrist I have heard large number of people suffering from schizofrenia say " At one point i felt like light " I don't want to indicate that Jesus was a schizophrenic (if he ever really lived) but there are significant clue he was...

  • @LOLYPOGY Hahahahahahaha

  • @LOLYPOGY Science has proved it is light that holds all things together.(atoms,cells,dna,) Light is the "glue" that holds these things together that make life possible-

  • @shotsxxx

    you do NOT need light to get life . It has been found plants in caves with 0 % light with houndreds of different colours.

    Check your facts

  • @ColpoX "WE NOW KNOW FROM OUR UNDERSTANDING OF QUANTUM MECHANICS THAT LIGHT IS THE FORCE THAT KEEPS ELECTRONS TIED TO THE NUCLEI OF ATOMS AND ATOMS TIED TOGETHER TO MAKE MOLECULES AND THEN FINALLY, OBJECTS" How does that work for straight facts?

  • @LOLYPOGY Doctors don’t know where spiritualism ends, and mental illness begins. We are made of Divine Light. So there is truth to that. By today’s standards he would be considered schizophrenic. Just because you can hear and see things that other people can’t. That doesn’t mean that it doesn’t exists :)o*o

  • @TimeTravelTruther Doesn't mean it does exist either, especially with the brain being prone to screw ups. You are classified as insane when you insist that something is true, with no proof at all that it happened or is possible, and refuse to accept that you have no evidence to prove it and continually insist that you are right.

  • @Shyhalu OK lets talk about the person that felt like light. In Quantum Mechanics they say that all things are made of frozen light. That includes flesh. Have you seen how some people like glow and some are dark. Truth is a mater of perception. The truth is he felt like light. He got a message from a higher intelligence with in. So you blow off there feelings thinking your truth is true. In Quantum Mechanical truth that we are made of light :)o*o

  • time is a man made trap, dont you get it.  we are not really in the year 2010 use your brain

  • @jcost2012 Dude...I am sorry but you are a silly little person. Time out of the Equation? Time is one of the BIGGGGEEESSST units in Physics.

  • take time out of the equation, there is no time in space dummy

  • Meaning that the flow of "absolute" time is constant, but our perception of it is what gives the apperance of a variable flow of time. After all our peception of "reality" is mainly due to our brain's interpretation of "light" reflecting of objects. This is what causes the inapropriate measuements of "time". It is as if we are measuring "perceptual time" and not "absolute time".

  • The way I see it, it's more of a synchonisation and delay of information then anything real and concrete with a time phenomenah.

  • I seen many many videos and explanations of the time dilation and time travel questions. However if space and time are tied as a single mech of "fabric", how it is possible for either to be a real physical phenomena?

    Meaning that I have seen the experiments that shows 'clocks' with time difference when they are moving faster then the other ones. However I have yet seen any experiments that show a biological difference due to this "time" variences. Is there such experimental data avaible?

  • WOW thank you very much... never thought of space-time in axis/component form ever before... it's MUCH MUCH clearer now... i knew most of the stuff said here but NOT IN THAT WAY.. wow. that totally gave me goosebumps, thank you very much. :D

  • This just dont make sence the universe as every atom,planets,stars, is probably round therefore there is no difference wich direction in it you travel its all space!!! time is only something that we get the illusion of that exists because of the movement of the planets around the sun. If you could travel faster than the speed of light you would not go back in time but only see images of the events that has happend before

  • @boxingisbest It does not make sense to most people because no one directly experiences a world where objects travel close to the speed of light. We also experience the world as 3 dimensions not 4, so it is hard to understand that travel in the 4th dimension is travel in time. This is why Einsteins science is considered among the hardest to understand, but even though it seems like nonsense to most people, it is real and there are many experiments that prove it.

  • @michalchik It is already proven that time travel is not possible because then we would get visited by people from the future :P

  • @boxingisbest That's true. Einstein's theories also showed that time travel is not possible.

    If you could go faster than the speed of light, it would be possible, but your can't so it is not.

  • @michalchik I just realised something, when for instance hubble is looking at stuff lightyears away its looking at the past! wich means if there was a shortcut or we could use teleportation trough space we could in theory use a telescope from that point lightyears away and watch how our own planet was before!!!

  • @boxingisbest If such a thing were possible, you are right we could :-)

  • @boxingisbest I don't pretend to have yet grasped all that's being explained. But you're certainly correct. And not just for Hubble of course. Our own eyes see the moon not as it is now, but roughly 1½ seconds previously, the sun as it was 8 minutes ago and a star, say 1000 years ago. The nightsky is a visual journey into the past.

  • @boxingisbest Yes, that would be very interesting indeed. Wish I could be alive in that day and age where inter-universal travel is possible, and we can view the Earth's history... What an interesting thought!

  • @boxingisbest just how would you send that knowledge back to earth ?

  • @MrNadhazi If we used a wormhole to reach outer space, placed the hubble telescope, looked at it, and went back it would be possible.

  • @maiahi0 That is if the wormhole doesnt wreck the telescope to pieces, and the only way to counter anti matter is by creating a vast amount of positive matter around the vessel which in theory would be larger than earth itself. which we are not able to do.

  • @MrNadhazi We aren't able to do any of this in a matter of thousands of years. That's sad. I aren't afraid of dying, but I want to see the evolution of mankind. The way things goes. All I need is a VERY fast car...

  • @maiahi0 Haha ! Yes very true indeed! We just need to figure out how to move faster than light... ;)

  • @MrNadhazi It takes a lot of coke...

  • @looncraz you do realise its not possible right ? ..

  • @MrNadhazi Depends on from where you're measuring.

    You can, theoretically, move space with you at the speed of light, and then accelerate within that space to travel at or greater than the speed of light. Relevant to you you are traveling much slower than the speed of light, relative to an outside observer you are traveling faster.

    That said, it was obviously a joke ;-)

  • @looncraz That actually sounds interesting, but if that is true, then how do you know that our universe is not part of a bigger universe and that our universe is already traveling at a given speed? Now if that was true then we do not truly know the speed of light.

  • @MrNadhazi Our universe is part of a plane in which numerous other "dimensional" planes interact. A certain number of those planes interacted at a given instant and caused our universe to spawn ( the big bang ).

    Looking back through the layers we see 11 dimensions interacting, though we may or may not be correct.

    Gravity can warp space/time so a gravity engine is similar to what I described. Except there you don't warp space in 360 degrees. Watch Futurama, that's the real way it may work...

  • @boxingisbest actually you couldn't, the light from what the earth looked like before would be out of our solar system, and ^teleportation^ isn't even a word, if you mean teleporting that's impossible through space as there's nothing there and you cant create matter. it is possible on the earth but it would require a lot of energy and that energy will go into the mass you're teleporting yourself into. @D you jelly?

  • @TheSunnycar In theory if you could teleport materials or use some kind of shortcut trough the fabric of space it could work. and space is not nothing it consists of dark matter wich of course scientists needs to study more before i can tell how it works but my guess is that space is like the water in the ocean. Drop a rock into the ocean and see how fast it falls trough then put some kind of pipe into the water and drop the rock trough the pipe wich ones faster?

  • @boxingisbest okay fine maybe dark matter but I still don't think you can teleport, maybe go through a wormhole -,- and obviously through the pipe, but space isn't like that, even though it has dark matter, we already know that sound cant travel through space, and as soon as you get into space you will get torn apart anyway from the vacuum. and having some sort of spacesuit would just require more energy

  • @boxingisbest that absolutely blew my mind

  • @boxingisbest Yup, that's how we've gotten most of our info about planet formation.

  • So i get what the video is saying. and i understand how they are looking at it. but i do NOT understand how you can come to the conclusion that time will slow down when moving. it stands to reason that is i am traveling through time at the maximum speed (wich i am right now) for say an hour then at the end of that hour i would still be in the same spot.

    BUT if i was moving then after an hour of traveiling i would have still traveled for an hour. reguardless of distance

  • ... in other words... i could sit at my computer for an hour and my wife could sit on the couch for the same hour. after one hour we would both be sitting where we are now.

    NOW suppose during that hour time fram i went to the gas station instead of sitting at my computer and came back in one hour. my wife would still be on the couch and only an hour would have passed for both of us even though i traveled and she sat still.

    so to me distance should have no effect on time what so ever.

  • So... no lets suppose me wife was STILL sitting on the couch and i hopped in a space ship that was going the speed of light. i traveled for a half an hour and turned around and came back. by the time i got back ONLY 1 HOUR would have passed for both my wife and I.

  • @Bajungadustin

    No. According to relativity, your wife would be long dead upon your return. In fact, from your point of view, you would have traveled into the future. For every minute you spend at 0.999999999999999 the speed of light, 42.53 years pass on Earth. The closer you get to the speed of light, the slower time passes for you. Or, from your point of view, the faster time passes on Earth.

  • @mtszabo i get what your saying, but i dont think it would really happen that way. i think time is just a relative term. we describe time as the passing of events. the passing of past events has always been around but the idea of time is man made, and i think that what we call time will continue to pass at the same rate reguardless of relative perspective. i mean i get the math and everything i just dont see it being possible. i think its a neat idea but in practicle application wont happen

  • @Bajungadustin

    Ah, but that's the thing....We've done numerous experiments that show it *does* happen, exactly as the theory predicts it should. The faster you travel, the slower time passes for you. Of course, you still experience time the same as you would normally. But to an outside observer, time is slower for you. For you, time is faster for the outside observer. Time is relative to the observer, hence why it's called "the Theory of Relativity."

  • @mtszabo ok thats all fine and dandy... BUT... why the do they call it a THEORY if its been proven... why itsn't it "Einstein's LAW of Relativity"

    i mean if people are proving it actually happens why hasn't it been upgraded to a LAW?

  • @Bajungadustin

    Because that's how science works. Theories remain theories until someone comes up with better theories to replace them. There are very few things in science that are classified as "law" because scientists are extremely skeptical people and are always testing theories to ensure that they hold up. As soon as one doesn't hold up, the theory is modified and then they test that. So, until we can travel at light speed, it won't be "proven", but with all experiments to date, it fits.

  • @Bajungadustin 'theory' in science is something that has been observed and tested for THOUSAND of times before it's called theory.

  • Comment removed

  • @Bajungadustin it's not just distance, it's velocity. If you went at 1,200 miles per hour, your gas station being 600 miles away (1,200 miles round trip)- when you returned you would be 1 second younger than your wife. You would not notice this effect. Light moves really fast: at 186,282 miles per second. (anyone please correct my math if it's inaccurate, but I believe I have the gist of it.)

  • Check out "WARS OF TIMES by LUN"

    at Amazon and Barnes&Noble online bookstore

    A world like you've never imagined before!!

  • what nerds

  • If there is something faster than light we cant see or measure it. Yet anyway. With slower time you dont travel backwards, you just slow down. Are everything still there a second ago? Or if I travel or are left behind in time, Am I alone?

  • light can travell through space at the speed of light .if you could find somthing that could cling on to the light then and travell with it then we could travell at the speed of light.

  • Has some one prooved that moving with light speed will contract time to zero and that if you are moving faster than light, value of time becomes negative... that's just a theory. it's fantasy unless prooved as nobody can attain that enormous speed.. and if it is true then tell me what would be its benefit or outcome to us

  • @shayzoo

    einstein also predicted that it is impossible to travel faster than the speed of light.

  • @DanielleKaplan1115  lol at this spam

  • My inability to understand this topic enables me to understand something else - Albert Einstein had a beautiful mind.

  • @DarkAngelSupreme lol Faggot

  • @DarkAngelSupreme ha, i think you're capable of understanding. it is really tricky to get your head around. watch this agian but disregard what you know about time and distance and allow them to be reconstructed in a new perpective.

  • the big poblem is that Einstein also says that you can't move faster than the speed of light...

  • Amount predicted by relativity how do you figure that out.

  • So I guess the argument is how much or how fast is time reduced by the speed of light. We need a unit of measure of slowed time first and then we can just use multipliers from there.

  • Ok lets make the argument that you did achieve the speed of light and was faster exactly is there a way to calculate where you will end up as in how far in the past will you end up in the past. Think of Back of the futur as the can you acurately predict the exact point in time you will end up based on traveling at the speed of light and from time duration or in this case lack there of in time duration.

  • I wonder if Stephen Hawkings was wrong and we will finally figure out how to travel back in time.

  • If special relativity isn't real, then your GPS devices wouldn't work. The satellites use Einstein's equations to predict when and where you are.

  • This is wrong, you cannot compare North South to Time and Space. time doesn´t exist it´s a human invention

  • @bicnarok The methods of measuring time are human inventions. Time existed long before.

  • @bicnarok idd, he can't compare N-E to Space and Time. time does exist just that u can mesure it in diff ways. secs, mins, hours, years... and i believe time measurement may be influenced by speed but NOT TIME ITSELF. speed of light is fastest speed we EVER know of but i believe that in hundreds of years maybe, they could find smth faster than speed of light cause as light is not being desintegrated cause of the forces, smth can possibly go faster if u know what i mean ;) this is my theory.

  • time is infinite both past and future

  • This all opens up far more questions, than solutions.

    If this video is true, then ALL space science must be open to question, since it means that the measurements used to guage the distances of far off stars and solar systems, could all be WRONG, because they could have all happened at the same time, but we are seeing them at different times, due to "relativity" (i think).

    If so, then EVERYTHING out there, could, literally, be a flat black sheet, with holes in, which let the light through.

  • You could never travel back in time, whatever has been done in the past is done in the past and can not be altered. If someone did travel at the speed of light it woud seem to that person that he as frozen time becuase everything would seem to be not moving.

  • oh now i get it

  • wait ....so if someone masturbates at the speed of light then he wouldn't see their cum because his penis would just stop time ...right???? XD

  • im still lost

  • pretty easy example with that N E far example... nice

  • @turkishPR yes its not travelling at c or faster... by pulling, the change u created travels as a wave with a speed much less than c (actually its = the speed of sound in that medium). & BTW thr isn't any perfectly rigid thing... so the rope will get stretched like an elastic for the 8 mins...

  • @esisimp123456 yea i found the exact same answere somewhere else. thx though for replying. these things are mind boggling.

  • Shit this is wicked

  • awesome analytical video!!

    now anyways,.... how do i go to the year 3000 again? ......like the jonas brothers... xD

  • very good video.......

  • Very nice vid! Thanks I just dont know tho, if the current idea of time, satisfies me. I understand that one can measure "time," but I never have felt as if time, is an actually entity. Is time what we measure? Or is what we measure time? I dont see how I can travle back in time, when time may very well simply be an illusory experience of a finite system. Would we segment our existence into years, months, days, hours, minutes, seconds if we were infinite? After all isnt that all time is?

  • @arktheball Omg i have been saying that for years!!

    No one understood what the hell i was talking about :D

  • @jordancwebb Haha nice to know another person who shares my idea XD

  • @jordancwebb:

    Saying what ?

    I know what you mean. I have thought of things, and seen them yrs later, after all my friends thought i was a babbling idiot. YOu give up on your own contemplations of things, but then you see soemthing yrs later (trust me, im 43, this has happened loads of times, muchly to my regret), and it turns out that your friends were all stupid, and you were actually onto something.

    But WHAT were you reffering to ?

    (ps - NEVER believe any friend's stupidity)

  • just think about that . if we actually travel faster than light. and we actually travel back in time then we would travel bAck in time so much that we would be in thqt time where we are just getting througH time which means that you would be stuck in time which also means that time is non paradox and so non bendable , lol that night actually be true, well it could be, but well im just gonna wwatch doctor who :)

  • ok, ok

    whats the speed of our galaxy in universe, or our solar system in our galaxy? whats the speed of earth lookin from the null point of the universe. how do u know that c isnt exceeded already.oh god, we dont know what light really is. this topic is millions of years ahead of its TIME

  • @cauda123 " we dont know what light really is."

    Yes we do. Light is a form of electromagnetic waves, at a range of frequencies which our eyes can detect. We know it's divided into handy chunks called photons, and we know how much energy each photon carries. We also know the underlying mathematics of light, photons, energy, etc.

    Of course, there may be new things to learn about light, but this is never going to overturn the basics.

  • I believe a greater understanding of the dynamics of light and time could explain the paradoxes of quantum mechanics. It looks to me like time moves at the speed of light and energy and mass slow it down to form their own spacetime geometry.

  • holy fk, waw i got it

  • Great vid... well time here on earth is nothing more that the earth rotating around the sun.. thats why we have 60sec=1min, 1hr=60.. 365 days to orbit around the sun... now if our orbit was smaller, then we would have less than 60 secs in a min... Time is also defined by gravity and how fast we are moving around the sun... So if you would leave earth the time in space is alot slower since you are not in the orbit. So I guess in time travel you can only go forward not backwards

  • @Scuby04 Yes, yes, you got it. You cannot go backwards in time. Think of it this way; space and time are one idea called space-time. You cannot have negative length, negative, width, or negative depth. Similarly, you cannot have negative time. You have to think on 4 dimensions, which is quite difficult, and I'm not completely there myself, but getting the idea.

  • well thanks thats a gr8 load off my mind, now if u would like to explain wat the fuck u r talking about?

  • If it's made easier, then I must be an idiot!

  • @talking1717 Yes you are, that was pretty simple, watch it again, but this time pay attention.

  • @talking1717

    You are :)

  • @talking1717 ur ryt

  • I struggle to comprehend how traveling faster than light would allow us to go back in time. I also struggle to comprehend how traveling faster slows down time. I don't understand the analogy drawn here between space/time and north/south because I don't understand how time can be a dimension in the same manner that distance is.

    I guess I'm too young to understand these things. My brain hurts.

  • well we don't know for sure what can happen if we travel faster than light as it's a test that is impossible to take, so it's a theory. the most common way that is to get around this is to try and bend time and space, like bending one side of paper, the sides now closer together. if one side was year 200 BC, and the other side is our year of 2010, then bending time you can reach the other side of the paper, which is year 200bc. now the problem is a time machine can't travel before it's created.

  • time is just soimthing to travle throw the easy way it to it to no try to think of as something you came see out side of twhat bappens that might help you

  • @kokofan50

    That would help, if we could read whatever the fuck you just said.

  • i was trying to say ( badly at that) that time is its not somthing to be looked at like the 3 we all know and love and think of somthing you can what happens to thing insted of the first 3

  • Hi Magzillas,

    The slowing of clocks due to high speed is a theory called special relativity. Not everyone believes it. There are other explanations for apparent time dilations, a problem some people are grappling with now. Einstein's theories will probably be overturned this century.

  • @SuperMagnetizer I personally believe that Einstein's theories will remain true, especially when it comes to time and space (or space-time). Experiments, thus far, all seem to point to the conclusion that Einstein's theories are correct. No experiment (laboratory repeatable experiments) has been able to disprove his theory of time. I stand firm in the belief that Einstein had it right.

  • @Magzillas

    The idea behind relativity is that the speed of light is always the same, no mater at which speed you observe it.

    This is only possible is if time slow down when you go fast, to compensate for your speed.

    Lets assume speed of light is 100 speed unit, and you travel at 50 toward it. If you add those up it give 150, but this is impossible. So in order to make it "look" 100, the time has to slow down, by 66.6%. (My math might be wrong, I'm just explaining it how I understand it)

  • I might as well point out that when scientists says that the universe is expanding faster than the speed of light(c), it is important to note that the matter isn't actualy moving faster than c, because antything that has a mass can't move faster than it.

    The space (mass less) between object is expanding. It is therfore not limited by c.

    In fact, object aren't really moving away from each other, the space between them is expending which make it looks like they're moving, but they aren't..

  • @vava54own So close. Not only does time slow down, but length also compresses in the direction of travel, dependent on the speed at which the occupant is traveling. Gotta remember that space-time is one thing (4 dimensions perpendicular to each other). Ouch, thinking about 4 dimensions hurts my brain.

  • @Magzillas:

    """

    5 months ago I struggle to comprehend how traveling faster than light would allow us to go back in time. I also struggle to comprehend how traveling faster slows down time."""

    Well, im 43, from england, nice to meet you. I struggle, but do not completely fail to understand.

    It seems, to me, that the ONLY actual truth, is the LIGHT - not us. ONLY the light is the true source form which all things can be measured. Jesus said "I am the truth, and the light" (but WHEN)

  • How slow was the clock on the plan compared to the clock on the ground - anyone know?

  • we need like a solar cell that can get energy from the sun faster lol..

  • first try to travel faster than the speed of sound i.e 320m/s, then think about light(3 X 100000000)

  • we view far away stars as they ARE in the past, but if we were to approach one the light would reach us more quickly and it would become in the future, but traveling faster than the speed of light, we would reach the star so quickly that it would stay in the past, once we slowed down though the star would be back in the present

  • This is all true and possible. Time Travel can happen theoretically. The only problem is how do we reach that speed.

  • @JohnTitor41 This may be the way:

    /watch?v=mGrBNtJjsU0 <= Quick explanation

    /watch?v=75ARLL9YBsk&feature=r­elated <= Discovery Science Program

  • hurt my brain

  • If you travel through space faster than light through a wormhole (stepping into a wormhole to instantly appear somewhere far off in space, which light from where you were hasn't "traditionally" reached yet), which is mathematically possible, you would travel into the future. Traveling faster than light in the traditional sense presented in this video would cause you to go backwards in time, but this is not mathematically possible (by "traditionally" I mean just mechanically moving faster than)

  • life is more meaningful when it is limited,,,and we will appreciate time more when we cant repeat it...

  • How can you have 'negative' time if you cant have 'negative' space? Or maybe passing into these negative values could allow for time/dimension manipulation

  • This is why people who exercise live longer because they are constantly moving thru space and time slows down!

  • good observation XD

  • So...I guess all the experimental data which confirms all of the predictions made by relativity should be ignored and we should just take your word on it?

  • if there was such things as time travel our great great great great grandkids would have already visted us, this would also mean that our future has already happened or that there is no difference between the past and the present which would mean that we are really not even here

  • Well, Special relativity doesn't say we can travel to past. However, its already prooven that time dilation works, and theoretically you can travel to future.

  • i agree, travel to the future is the only plausible concept with time travel

  • duhhhhh..........when's lunch?

  • Ok, this is my interpretation. If I'm traveling at the speed of light time stands still, but if I'm traveling faster than light then time PASSES, i dont travel back in time. You would actually become younger wouldnt you? I think the only way to travel through time would be to jump inside a wormhole lol srry i really dont know what I am talking about!

  • @cordguitar1 No you can't travel faster then or even the speed of light, you'll just kill your self and turn into energy, why would you want to jump onto a worm hole, do really want kill your self.

  • Just tell me how to travel backwards in time, i just want to go 10 years back with my current knowledge thank you.

  • You cannot travel backward in time. Space and time are part of the same fabric called space-time.

    You can't have negative time as you can't have negative length.

  • surprisingly you can have negative time. eg. the time before a race could be considered negative time since the time that the race started at is 0. Any time before that would be considered negative.

  • @CuprousChloride No it wouldn't. For time to be negative it would have to be running backward. Time cannot run backward, it runs forward. Time before the race is not negative. It's just time running forward until the race begins and that timer is initiated.

    You can't have negative time, just like you can't have negative length. My tape measure starts at zero. There is no negative numbers on it. I've checked the entire length.

  • You can not have a negative length, just like you cannot have a negative amount of time, but like the three "physical" dimensions, you can travel in them in a positive and negative direction. Time is a fourth dimension that in theory you should be able to travel back and forth through. Travelling through time in a "negative" direction is not crossing a "negative" amount of time.

  • @Perrickan You can't travel a negative direction. You are always still traveling a positive direction, whether you are traveling back (or backwards) along the same path you just arrived on. If you traveled five feet North then returned to your original starting point, you covered 10 feet, not zero.

  • It is impossible to move back in time cause distance equals time so if i was to move faster then the speed of light i would be making distance with no time with does not make scene cause u cant have distance without time,which means that i am standing still.

    correct me if i am wrong please

  • Time Dilation is a nonsense. The guy who invented the atomic clock pointed to a creative rounding-up of the numbers in the aircraft experiment! It's wishful thinking from the people who want to believe. Let's keep it real.

  • Yeah, I don't think time actually exists other than as a concept. I seriously doubt time travel is possible.

  • You can't travel backwards in time, because that would allude a way of being in the same point in space as you were in the past.

    In other words, even if we hit above the speed of light, there's no way to instantaneously "travel" back to observe what point in time you are in, back in the original location.

    If wormhole theory were manifest, then maybe... but that's getting beyond sci-fi.

  • Time travel is only relative, you can not move yourself back into time, it would only apear so. since you will be moving faster than light particles (if you were able to) Moving away from an object, as say, twice the speed of light. Then looking backwards, you would be able to see stuff on earth in reverse at normal speed.

    So its only relative because you can only observe back in t
