  • Is that richard hammond's dad?

  • it is good idea to make time machine to go back to the past. so we can get marilyn monroe and micheal jackson and people who died from september 11, 2001. bring all the family back from the past. also to cure cancer and other disease. stopping the war and else. we can ride old fashion car. it be great!

  • If time travel was possible then someone from the future would come here with concrete proof so it's not possible. Unless there was a way to "record" time and then go back at any point from when recording began. Like with a camera

  • @giggidygoo17 because there are infinite numbers of parallel universes, that's why nobody come to visit us, time travel is possible because gravity is time , alliens have this shit ;)

  • if time travel was to happen then how is it possible to go to the past do something to someone without it effecting what ever happens in a parallel universe in the future and if it was possible to travel into the past how do people know that you would be going to your world in the presents you could go to the future in a parallel universe.

  • Lol reminds me of Stiens;Gate

  • 3:07 I dont want to know if the world is determined!

  • Watch out for that first trip, you just might come back with your head stuck in yur ass.

  • I want to slap the Japanese woman.

  • Selfish, Rational and Good Willed minds enough said

  • lets say Mallett builds a time travel machine...lets say prof Mallett steps in the time travel machine and he flips a switch...he disappears...how can we know if it worked??? how do we know he didn't die in the process?? better question-What do we do then?? Do we say " Time travel is possible" or do we send more people to die(of course unaware that they are dead), to somehow prove that its possible??

    point being-You cant physically prove time travel...

  • @nemke1990 i think they would tell the time traveler to write something on a paper and go put it somewhere or prolly burry it in the pass and they would see it in the future unless someone sees it and take it

  • @nemke1990 yea u can...the minute he builds the time machine he could be receiving messages that it would work or something along those lines bc u need 2 points in order time travel thus u could only travel back as far as the first time machine was built...so if something was sent through the machine back to the past it would immediately reach him the moment he built the machine (this is of course under the assumption that the parallel universe theory coincides in this one instance though...

  • @KMutlu17 my comment got cut off n i dont feel like rewriting it

  • interesting that the London City Hall is a museum of time travel in the future...

  • But i wanna stay in my universe :(

  • so we exist in a vast sea of infinite amount of universes and within one universe we exist as individuals within one space & one time but this means that you can have exact copies in terms of matter in these universes and they are exact copies but there is no exact copies in terms of consciousness because if there were then we would live an infinite number of lives at once hence consciousness is more individual & different than atoms & consciousness must be created not by atoms but something els

  • If time travel is possible then if someone reads this comment in the future go back in time and knock on my door now at 20:20pm on February 19th, 2011 bt I doubt it'll work bt imagine it did xD

  • wanna go to the future? go to bed. when you wake up you'll be few hours in to the future

  • whoever tests the time machine out will probably be gone forever never to return to the original universe

  • Which probably already happened. It's just that since he/she is gone, we don't even realize it and wouldn't it be pretty much impossible to come back to the exact universe? They say there are an infinite amount of them 0.o

  • and we keep making up universes cause we still dont understand the fundamnetal nature of our own

  • If Bertrand sees Albert's photon clock to be slower than his clock and likewise Albert also sees the Bertrand's clock to be slower than his clock, then there is no relativity to speak of because the two separate perceptions cancel each other out...

  • who's up for some sub-atomic paintball? :D

  • goku can go faster than the speed of light...

  • on 5:50 he says if its on a loop ??? how . The future wont end so the loop will never go to the past.

  • am wondering say if you go to a parellel universe in which the world is 2 years behind the world in the universe in which you live. would be two years younger in the universe that is 2 years behind the previous one you were in? or would remain the same age just in a universe thats two years behind?

  • I believe every time we have Dejavu It is because the same thing is happening in A parrellel Universe

  • When i was small there was always this Kid Who looked out for me

    Its like he knew when Somthing bad was going to happen

    I never saw his face he always wore a Black hoodie over his face

    I never see him again and it makes me wonder if he was a time traveler

  • @danjosh7111 thats very interesting if its true, that someone you did not know just happened to appear when you were in trouble. did he speak to you? give us a couple examples of how he helped you

  • @danjosh7111 The word for that is 'pervert'.

  • hello can you please give me directions to the closest black hole

  • This is weird. I saw this as a boy years ago. I wondered what ever happened to that guy with the laser beam time machine. I recently discovered David Deutsch and am reading his book The Fabric of Reality. Now all these years later I find the laser beam guy (Dr Ronald Mallett) and find that David Deutsch was there all along! The past, present, and future as we have come to call them is stranger than we can think. We are actually in all three at once. Stretched out forwards and back. Literally.

  • 2:32 that what John Titor said

  • who is disliking this!!!!!!!!!!!!!!!!!!!

  • so what happen if we time travel and went to the wrong universe o.o

  • this explains why leonardo da vinci is so advance in his works ..

  • @w3warianite i know, but if this time travel is true, why aren't anyone from the future won't come and tell us right?

  • @quangluu96 im guessing we are on a steady non-interfered universe. hav u watched the movie back to the future? how orginally marty's dad worked 4 biff and when marty inferfered with his parents in the past it create a alternative universe in which was created by the time traveler (in this case it marty) and now biff works for marty dad.

  • @quangluu96 or maybe some geniuses here now were really part of the future, get me?? :)) hmmmmmmmm

  • Comment removed

  • so if we're jumping into all these different universes, wouldn't we belong to all of them? say if i left this one and went to another and lived there for 50 years. i'd aged in the 2nd universe. if i decided to return to my 1st universe at the time that i left.. i'd be 50 years older than i was originally and my universe would have been affected... correct? or is it like naria, and i could come back young? haha

  • @meganlovesince91 no you wouldnt come back young if you was able to get back you your original universe. see the thing is with time travel in the past is you are going to a different dimension. and the thing is with trans dimension travel there is a indent number of them. even in a million years with the best super computer you wouldnt be able to map the dimensions out so, How would you get home after your 50 years are up??? hope i put that in understand able form

  • wait in 0:03 if the ball changed to an 8 ball then he lost because he dint made all of his balls in and why are they celebrating if he lost?

  • @Durango281713

    because the opponent pocketed his 8-ball meaning he lost

  • @Refaie22 oh ok cus i dint saw him

  • anybody saw the movie One with jet li?

  • @FeeldahVibe001 Yeah I have...awesome film

    Oh, how come we can't watch part five? :@

  • @1eandr1 idk it must of worked and the government was probably like "K THANKS!" and took the machine and seized the footage

  • WTF, why can't we watch part 5???

  • @BikeMeAustin Because I traveled back in time and deleted part 5, wich means I didnt wach this part to know there was a part 5.. wich means I didnt delete part 5.

  • @isaco86 Ohhh I see, that explains it! ;)

  • @BikeMeAustin part 5: watch?v=HMv8fpmEPfs&feature=re­lated

  • @eoghan15 Cool, thanks!!

  • cant see the fifth part please help =(

  • the parallel universes interact with each other in our time. Is like if you hit you r self it will not hurt other peapole around you, but it will hurt your parrell you and you.

  • the clock will slow down and stops , but why will it run backwards ? 8:28

  • 0:02 rofl

  • oh yeah sure, you can borrow my black hole

  • EXACTLY! it makes so much sense = ) to travel through space at lightspeed you must cause the atoms to simply behave as if they were photons. much like the example they gave of the 8-ball and the yellow striped ball being two versions of the same reality. maybe i understand spacetime!

  • Whoa... total mindfuck.... I love it.

  • That pool table demonstration is epic!

  • Skipping through universe,through universe,through universe,through universe,through universe,through universe,through universe,through universe,through universe,through universe,through universe,through universe,through universe....

  • so wait..... the earth isint flat?

  • i think a common intrenet phrase explains this all:

    WTF??????

  • So what, if you travel back in time YOU don't go... but another version of you in a parallel universe?

  • ...

    what happens if when you go to the otheruniverse you kill someone that was going to go into your universe and tell you how to build a time machine.....

    or if you go to the universe that a "hidden atom" came from and stop it from coming into your universe....

    *im 11, and im smart dammit.

  • @shoshanish Alright showoff. You're not the only smart 11 year old.

  • @LegendGamer472 im smarter than most, atleast most i know.

    some kid in my camp said he was smarter than me.

    he said that planet 51 was the first planet discovered.

    im like dumbass, that would be earth.

  • @shoshanish I'm just saying, no need to brag about it.

  • @LegendGamer472 im not bragging.

    im just pointing out that im smarter than most people my age, or atleast the ones i know.

  • @shoshanish Well... the thing is, I don't think anyone cares really. And I think you are bragging because there is no need to point that out.

  • If I can do what I want with time travel, Im going to have some great sex with a great woman

  • I would not want this guy to be able to affect destiny

  • is only me who started watching this amaizing consept beacuse of marijuana?

  • @doffykjekk beer for me

  • ...but free will is a superstition.

  • if you could send a particle into the past, just send back particles in morse code to communicate

  • if the multi verse theory is true then wouldnt paradoxes not exist considering thet the multi verse theory is an INFINITE amount of universe's.

    but then wouldnt that mean time isnt a dimension,because your only universe skipping?

  • @xxXchristofurXxx yes that is very true

  • @Morbidanteater INFINITE sorry my spell check is stupid

  • Personally, given other massive developments in technology like genetics and the telephone, and the predicted social effects of them, I predict that the social effects of time travel will be...

    Nothing really catastrophic.

  • mirai trunks didn't affect his own time.....cause he went to a the past of anither universe. Dragon Ball Z is far ahead this.I'm jocking, this is really amazing!

  • hate the narrator's creepy voice

  • i wanna see what happened to the guy the tried to collect "black hole" with a teaspoon

  • If it's not pre-determined, which I don't believe it to be, then christians/muslims/the jewish/etc/etc/etc....they'd all have to hide for awhile.

  • @Sniffeh

    Practicable - Adj - able to be done or to be put into practice successfully

  • 1:13 - 1:23 "The answer is that you would come into the past of an other universe. And that's really why there is no problem with free will."

    ... As soon as you do as you have to in this new universe ... Pause at 1:18 ... Arf, you thought you understood it well, and now you lost it ...

    Pfff... It's not time travel any more... Why would you travel into the past if you can travel in an universe where time is offset from our.

  • 6:16 "it wont be simple, but it would be blah blah blad"

    lmfao

  • If there are parallel universes, couldn't you still travel back in time to your own universe?and then try to kill your grandfather? Or would you automatically travel to a different universe.

    ... Couldn't you hypothetically travel back to your own universe?

  • Sooo ..... I'm not sure but I just think my brain cells exploded ....! WTF ...is this ? So friggin confusing ! ..... Am I even real anymore ?

  • Ok... so super man speed is "speed of light"... Then He travels...?

    Ok What About Goku... That Fool Is Faster Than That... Way Faster... How Come He Dont Travel?... Ok My Head Hurts...

  • if this theory is true then is it possible that we right now are living in the past that we are just living our lives and some from the future came to watch us so really we are living the past or the future. the crazy thing is no can know. you cant say we are living in the present. example 100 years from now a person makes the time machine comes back to this day and tells me im living i the past. I it is true!!!!!!!!!!

    im just a freshman in highschool but does anyone here understand me?

  • @n2oxide2 yeah, makes sence.

  • @n2oxide2 No such thing as the "now". you can break down 1 second unto an infinite amount of numbers. Zero only means non existance.

  • NO NO NO! SPEED AND DISTANCE! Is it is sub atomic it probably travels at near speed of light! GRAVITY of object WITH YOU affect you more to join as near by object can alter your direction or rip you off a layer. making up a Universe in the same place is dumb.

    laser going in a circle is not time traveling.

    Faster than light means only more distance to cross and so relative time is same.

    You would not see a clock go slower but more often and the circle would GROW with speed.

  • Thank you for this great info. Be Careful Ron don't give up your info to everyone.

  • yeah!!! let this guy modify Collider into a Black Hole generator!!! Ultimately we will travel to the past forever for US taxpayers money :)

  • Try telling a judge "the parallel unverse made me do it".

  • i would go back in time to give myself the time machine to create a twist in which destroys me of the old future to create the new me of the future from the time machine i would had given myself 20 years later ago. Understand?

  • superman turned the planet around for things to rewind he did not travel anywhere

  • hang on, travelling around the earth, you are no longer in an inertial frame, relativity doesnt even work!

    lets say we could apply special relativity here, firstly as bertrand approaches the speed of light, his time would slow and dilate. as for his obersevations of alberts clock, they would appear slower, as bertrand moves away from albert, and as he approaches they would appear sped up. although of course, no relativistic effects perpendicular to the plane of motion....

  • if you send a ball back in time to BEFORE you sent it back in time, its momentum and spacial positions would both have to be altered on arrival in order to effect THE FUTURE. however it is in existance in the past now, so it cannot cease to exist there by the fundamental laws. however, the reasons for its emergence at that time could become nullified

  • if the other universes can effect ours, we can then observe then also, since they interact. according then to particle theory, exchange bosons have emerged from their interaction, these alternate universes should be detectable.

  • MY HEAD HURTS AGAIN!!!!

  • so this is why my socks get lost in the dryer?

  • Wouldn't all the air in the time machine get set back in time too?

    thous creating a GIANT vacum cleaner and send all the air on the earth when the TM is turned on to the time it was turned on! Wierd?....

  • PA-ST!!!!!!!!!!!!!!

  • If i can travel in the past, i not marry anymore so i not have to listen my wife nagging today.

  • @driepintenbier Then maybe you can learn english aswell

  • @SuperEvilLemon, well my english is very good, only when i invite s.o. for a drink.

  • @driepintenbier Well its an easy way called leave

  • where the UFO's are coming from ? they are doing time travel for sure

  • i think if time travel will ever happen we would know by now...i dont think anyone will ever go back to the past from today back to the beginning of time because it would be in history already...someone from the future would come back to us not further back in time cuz we would already know.

  • @AmorAmbee

    Well, if you travel fast enough then time will pass slower for you - you can't notice it because your reactions in your brains and everything else that you use to observe is also going slower. If you'd live near a black hole for what seems to you 10 minutes, more than 10 years could have passed on Earth.

  • eintein theory, if you travel fast enough. you would be moving at a different time. Like you jump on a spaceship that can travel at the speed of light nonstop then back to earth in the year 2110. You might have never aged, but everything on earth would have been 100 older.

  • a rotating black hole is a worm hole. If you really wanna know what they are talking about, watch the movie EVENT HORIZON..in which terms means the cusp of a black hole...

  • @theclash24

    That movie is forgetting that a black hole would rip apart anything near it, not even the most extreme dense objects (neutron stars) can rival the force of a black hole, a 1 by 1 centimeter neutron star cube would wheigh a hundred billions tons on Earth - just to show you how powerful a black hole is.

  • still a good movie-- but its a theory and in THEORY they would have created some sort of device to counteract going through the worm hole. I'm assuming the worm hole time travel theory that stephen hawkings agrees to would have a ship capable of going through it.

  • @AmorAmbee

    naw, some people live their whole entire lives learning it. If you are told about it in basic ways you'd understand it pretty easily.

    basically the theory of time travel has to answer a bunch of questions before the theory can even LAUNCH an answer to the first question "how to time travel" AKA how do we travel faster than light, how do we avoid paradoxes, how de avoid this and that...once thats answered we can answer, how do we time travel.

  • @Satofire16

    well-- energy transfers and in fact doesn't dissapear. Everything is reused or chemically or subatomically changed...THUS a cell in your buddy currently could be a piece of an atom from 50 billion years ago.

    they made a movie about it, the main character was trying to unlock the coding of energy and cells to VIEW what they have viewed within their times!

  • sdasd

  • Wow infinite amount of parallel universes, these kind of things are so way beyond the grasp of understanding even I, as hardcore atheist, would think of the possibility of a God like entity.

  • @ApocDevTeam

    God. If these theories are remotely correct, it would take a sentient being being able to TIME travel and travel between worlds without having to mess with time, AKA...being in one corner of universe A and being at the other corner of universe B without even a second occured.

  • man this is crazy! it would be cool if a time machine was invented but we wouldnt be able to use it.what ?you think they would mass produce these things like Xbox 360s ? heck no Terrorists would use them like crazy

  • @straightupmenace

    that is one of the scarey things about time travel. What would happen, bad man goes back in time and kills the guy that invented time travel.

    BUT than again...bad stuff always happens with technology...A-BOMB built for good, end the war...but...it killed millions of people...the computer...hackers have destroyed many lives and stolen many identities...time machines...can you imagine?

  • \ / ----- He meant that they interfere with each other only on a sub atomic level (smaller than electrons), but for the macroscopic world, they do not.

  • there is no macroscopic world. There are only particles and emergent properties that they take on as scale increases.

  • He says these parallel universes are interfering with each other all the time ( 00:42 ) then

    " nothing you do there ( in a parallel universe ) will affect

    the universe that you came from " ( 1:28 )

    Wait a minute...

  • @cardhang they interact but what you in the other universe will not create a paradox and change the universe you came from

  • @cardhang yes you can rape britney spears in that universe and return to your universe like nothing happens..

  • a rotating black hole remember dec. 9th norway spiral like it up

  • well i not a scientist but if stuff in space seem to be ahead of time when it moving fast.. and i kno if ur in a car and a guy is walk the ppl on the car will have a slighty different time from the person walking that i kno for sure so if speed have something to do with time and light is time at a super fast pace how about we slow light down to understand it better just idea i had in my punty mind i have lol

  • @dDemolisher7 you cant slow light down? its constant. if you slow light down then it isnt visible light. it becomes something else on the spectrum. maybe ultraviolet rays or something, but visible light is at a certain frequecy for a reason. i believe anyway

  • well the light at isnt visble is the light that moving the same speed as we r so i think that is a start

  • @drunkman12345

    Maybe because Bertrend is now looking at Albert's clock which takes longer tricks and eventually would go backward as Bertrend moved closer to the speed of light and then beyond it( if it were physically possible). So, Albert's (and the world's) time would move backward when we moved faster than light.

  • In the first sentence I meant ticks not tricks, lol.

  • it would be nice to slow light down, but that's the problem. No matter how fast you are moving, light is always moving c=the speed of light faster than you! Even if you have a really really fast car. So even if you are going the speed of light, light is still moving at the speed of light faster than you! It is a constant. Can't be slowed down, even if you catch up with it (which you can't or you take on infinite mass.) To deal with the constant, time itself slows.

  • someone explain this to me. So the way for time travel into the past and the futur are the same? going really really fast? but then why does this first say (in an earlier video) that when the rocket speeds up, one hour for the person in the rocket might be 100 years for us.....and now.....when he speeds up everything around him slows down. are these NOT conflicting? ugh.

  • im no scientist but i mayb able to answer ur question . think of the theory as if the faster u go in a rocket, for u, the time will slow down inside the rocketbut out side the time will remain the same.. so by this theory to go back throu time u will need to go in a negative speed. but thats impossible.

  • so instead u take the barrier of speed which is the speed of light and the faster u pass it the faster the time goes by for u and u go back in time. so to review you go faster and faster into the future while going closer to the speed of light and after ur "pass it" u go back in time.

  • @nyg8128 alright. it was just confusing because first they said that the rocket that was moving had ITS clock slowing down...and then the seond time around they said that the clock in the stationary rocket was slowing down. only difference was one was in deep space and one was circling the earth.

  • omg i wish the paradox is true because i could go to ma school n fuck all the fit girls n do wot ever i went smash windows n shit n when i go back everythink would be normal SNEAKY!

  • @mg08mg

    ur a future to be rapist lol.

    but i'd like to do that too

  • he should've just bought delorean

  • OMG I just figured something BIG out!!! They'r gonna start this time machine first time around December 2012 aren't they!! (All pieces locks together, anyone??)

  • people's existances are probablity as balls are.

  • and once you left the dimension you started to travel from, how will you come back to the same exact dimension???

    maybe Dr mallett will be able to go back in the past of another dimension,save his father from death and then go back to present time,though in a third dimension where his father is dead anyway because of natural causes (aging) and his wife is a bitch!

  • as long as time travel didn't happen it'll always be a bla bla bla bla bla bla

  • get me a spaceship and let me be in space for 1 hour then come bacK!

  • Or I might have an interstellar wormhole!

  • Comment removed

  • THAT EXPLAINS WHY I ALWAYS LOOSE MY SOCKS! lol

  • I actually put a cd in my play station one time. and then the playstation would say "no disk" ,so i opened it and the disk wasent there! i swear to god like 2 years later the same thing happened but when i opened the play station all i found was the disk that i lost 2 years ago!!!!!!!!!!!!

  • @tikhon2111 Than you must have a very strong and fast laser in your playstation. ;)

  • @tikhon2111 lollz

  • @algatroy

    yeah right, they interfered with the parallel universe of single anti socks :D

  • that guy looks alot like steve buscemi

  • I think this is a small attempt to say that free-will actually exists, for which there is no proof. Sure, you can say you have free will, but how can you prove it? Everything that you do, is something that you would have done, so did you actually control it?

  • This video is just saying an error has occurred and is not playing

  • Hmm.. indeed this video is just saying An error occurred, please try again later.

  • To me this proovs that time travel isn't sothing that can be done, because Time is an illusion. What people are doing as the "time travel" is just jump from one deminsion to another

  • But wouldnt you affect the universe that belongs to that past universe that you go to and change ? :) Must affect some future universe somewhere, that belongs to that past universe...

  • Why are they not taking the 'twin paradox' into consideration when they talk about the two twins Bertrand and Albert??? Why are they not talking about the change in frame of reference?

  • erhm? Did you see them all ? :) They are talking about the paradoxes

  • I hope you understand what is the 'twin paradox'. If not, please allow me to explain it: One of the twin remains on Earth - A. The other flies away at speed of light (c)- B. As per relativity, the change in frame of reference is taking place for both of them. B sees A moving away from him at c. A observes B going away at c. However, time slows down only for Bertrand and not for Albert. Why does it not slow down for both as per calculations of relativity? That is the paradox....

  • They do talk about that, only a little different example

  • No, in this video they are saying that if B travels at c, then for him the time on Earth or A will slow down.

    But relativity says if B travels at c, the time B observes on Earth will move extremely fast into future.

    These two statements are completely opposite. The second statement is exactly what relativity states.

  • This paradox has not been resolved yet. So B moves away at c, then he observes time on Earth/A passing too fast to observe. Completely opposite of what they are talking in this video. When you move at c, time stops for u/ur frame of reference and others move into future in relation to ur frame of reference. When B comes back, he will be same age he was when he left. However, A will have aged too much or even died of old age by then.

    Now I hope you understand what I find this video ridiculous.
