I guess everyone's hear the latest breakthrough as of a few days ago saying time travel may be possible at least at a subatomic level.
I wonder if something I've stumbled across could open new doors in scientific research. If you follow my link to see my first upload "Witness a Miracle" you'll see what I'm talking about. The first few moments after it comes into focus are key to watch, and it easier to see full screen. I swear this footage is genuine. p.s I'm not selling anything.
This is due to the 2nd law of thermodynamics stating that heat would always transfer from a region of higher temperature to a region of lower temperature until the system reaches an equilibrium.. And a system in equilibrium would stay in equilibrium unless a disturbance is introduced such that it tends to a new equilibrium, usually of a higher entropy..
The reverse process is viable because the sound and heat energy produced from the reaction would suffice to cause the glass to come back together and form the bulb as well as give it enough kinetic energy to rise above the ground and back onto the table.. But as he had put it, the reverse process is very improbable..
2nd law of thermodynamics! Entropy increases with time. It's why we see things break when they fall off the table rather than things becoming more organized as time goees by.
if something travels in time backward that means its matter will be duplicated
and its actually creating matter out of nothing or assuming that time actually consist of very large numbers of universes each one represents the smallest quantum of time and our souls jumped from universe to the next universe in the same moment like the video frames but simultaneously and that means there
is actually only one tiny quantum of time in which everything was manipulated
Time isn't real, its a stupid concept that people have gone too far with yet again, like for example: somewhere in the universe there is not nothing because nothing doesn't exist. Im so glad it took an uneducated 15 year old boy to tell you all that
@mewtwoschaos - Ha-ha, Stupid concepts which are backed-up by evidence, and also hold-up to public scrutiny. This is why calling scientific notions ‘stupid’, is wrong. Science is the best, and most accurate way we humans have of obtaining the truth, and exploring this Cosmos.
Just Cause Two has considered every neat portion of a video game, and packed it into the very best game ever before! If you actually would like to enjoy it for zero cost as opposed to having to pay money for it, merely go to JC2DownloadXcom (replace X with . ) .
So if we ever achieve absolute zero and all motion stops between atoms then would we hypothetically be able to send those atoms forward and backward through time?
it seems to me that those atoms would be unchanging until something touches it like a photon sometime in the future . if a person could freeze oneself and be thawed and awakened in 500 years it would seem like time travel to that person. going backward through time? wont happen just because your cold.
Someone got to explain this to me. The distance in classical physics is simply D=sqrt(X^2+Y^2+Z^2) but in Relativity d=sqrt(x^2+y^2+z^2+(i*t)^2). We can write the (i*t)^2 term as -t^2. What is this? People simply say that this is the fourth dimension. But not quite. There is a negative infront of the t. So longer it takes to travel that distance, it will be defined as being closer. eh?
I have no problem with timetraveling. If you have a relativistic time. But even with relativistic time travel there are still things we can not do. Like kill your parents. If you do that you won't be able to exist. There will still be a string of consequence that will be weave around the universe.
The killing your parents paradox has basically two endings. One would be that you CAN NOT kill your parents. The fact that you are alive now is proof of the fact that in the past everybody , may it be a timetraveler or alien or whatever, failed to kill your parents.
Second option would be that the timeline would get cut or split into a different reality. The movie "Deja Vu" mentions both of these theories.
I tend to not want to go the second option. Just because I have not thought about it. (It seems to destroy any possibility of ethics. )
How about this, maybe in the future some bad guys gets hold of the nuclear bomb to blow up the universe. And they have a time traveling device as well. And they want to blow up the world in the beginning. Murphys law says these conditions are quite possible. But still we exist. That means the future people are ethical. The future people are bound by a code.
good point. we could alow a murder of one's own parents. then we can regenerate the parents by one way or another. so the murder can still exist.
(But that could mean everything goes (including casulity), or does that mean things are going to get a little more complex.) It all depends on how much relativism in regards to time you are going to tolerate.
I think that the universe is stranger than we can possibly imagine.
We cannot understand the nature of time travel simply because it is so alien to us. Our brains have not evolved to process time as anything else than a "one-way street".
This is precisely the reason I think that our classical view of time travel is wrong.
I think that Schrödinger´s cat experiment explains that some elemental particles have the ability of being in two places at a time and in two different states,but when an observer looks at them,they take just one of the two possibilities or something like this.
@Ategato there is only one moment we live in but universes are changing
in other words time is only one point and cannot be a line if time traveling backwards is possible and to do this we must probably be in the same operation level where god ,angels ,dead people souls operate .
These videos are simply amazing. I watched Carl Sagan's Cosmos several times and had wished for an updated version, and this is it! I think about these things every day but always wanted more answers. These videos answer so many of my questions, while inspiring new ones. THANK YOU!
The beauty of your videos is its simplicity which does not rely on boasting about the insights by complicating things, unlike many in academia in order to protect their turf, but tries to break them down so a layman can understand them and probably even contribute to further them more.
Einstein has already proven that time stops when you travel at the speed of light,and string theory and quantum physics have provided a pretty strong theory that we can time travel.The shape of space,black holes,multiple universes,eleven dimensions,etc.I love it all...
i've always believed time isn't real. but is a word to describe motion, and whens. Like the location of when something happen. so i don't believe in "Time traveling!" at all.
Imagine if everything in the universe stood still (even atoms etc.) would 'time' exist in this environment (no motion to measure or perceive)...? Nothing would even 'age' because nothing is being disturbed.
Anyway, just a concept to consider! which gives your 'matter in motion' theory some sort of truth...
Also it seems that the more that matter is moving (even thoughts are energy matter) the faster 'time' seems to go. So by being active & expelling energy, matter trades time for aging.
You fail to explain the difference between "absolute time" and "measured time". Relativity is based on the measure of time and not an entity of time that is mutable. There is NO time entity; there is only motion and it is your motion reference that determines your time measurement.
I was actually thinking the same thing. I was thinking that to turn back time you would also have to reverse the order of matter in the universe and since that cant be done, i knew time travel to the past is impossible.
It makes perfect sense if you keep in mind that the universe is composed of tiny, vibrating strings of curled-up, 11-dimensional nothingness. They're bound to behave differently than musicians or dropped lightbulbs.
And if one can´t reconstruct the full CORRECT past, it´s impossible to travel back into the past because it wouldn´t be THE past if only one single atom is not part of it.
To travel back in time would mean to rearrange and reconstruct all the matter and every atomic compound.
The changing molecules of my body as well as the movement of the stars.
And that´s bullshit to believe; only "god" could do that!
You can´t just take matter (ur body) from the present into the past because in the past your molecules might have still been part of many trees of a forest.
That would mean you couldn´t reconstruct the correct past because some molecules would be missing.
The probability of a specific thing to happen is virtually zero but if you count all the possible things that can happen it is inevitable that something actually does happen, or at least that is how I explain it to my hopelessly inadequate lump of neurons in my head.
My brain hurts - excellent video though. God I wish I understood this stuff - I sort of do....did I write this or is it just my memory? Oh I've just thought of something else - have I? Yes but in the future/past of my thought sequence. It is highly improbable.
The first step for backward possibilities, is to stand still. Blanked mind, no forward thinking at all.
Things happens from causes towards consequences. No one can do opposite because there no permanent perception of "a moment."
At any case, being able to time travel means that time become irrelevant. The passing of thing have no meaning when there's the freedom to reverse. Progression could even stop at the rate where someone would be going back to change any little unwanted present, at will.
"The backwards sequence doesn't break any laws of physics..."
I don't know if I can agree with that part of your statement.
This seems to violate Newton's First and Second Laws of Motion:
"A body at rest will remain at rest unless an outside force acts on it. A body in motion will remain in motion with the same direction and speed unless an outside force acts on it"
The balls began in a static state, but begin to move and then accelerate without outside forces acting upon them.
well, by traveling backwards in time the only logical explanation would be that any force has an oposite direction and it occurs before even being produced. Pretty weird :)
You need to realize that we deal with probabilities when it comes to quantum mechanics and that he says it's not impossible but highly improbable for this backward sequence to occur especially the more complex it gets and even when this backward sequence does occur it's most likely to happen with electron pairs where an observer wouldn't even be able to tell a difference because the backward/forward sequence is the same. Newtons first and second laws don't explain motion on a quantum level.
I think you need to see it thermodynamically. The molecules of the ball are still in motion, the net motion averages out as 0 when the ball is still. However, the energy is conserved so there is a chance that all the molecules will use their kinetic energy in the opposite direction after the ball stands still. If this is not in a vacuum, take the heat lost to the air (now kinetic energy of molecules in the air) and surface friction into account as well. Not impossible, it's all molecules =)
While I can see the possibility of all the atoms in a billiard ball moving in the same direction at the same time, I cannot see them generating enough force for sustained movement and acceleration.
This is especially true in the case of the 3 ball, which dropped in the corner pocket. Even if all the atoms in that ball were moving upward, they would have to overcome the force of gravity in order to pop out of the pocket.
The molecules of the ball in fact do posess the energy to overcome gravity and go back up out of the pocket (again, energy lost as heat or friction would have to be collided back to the ball as well). Each instant the ball is falling it gains kinetic energy and loses gravitational potential energy. This kinetic energy could be turned back into potential energy by having the molecules 'randomly' move back up in unison (which is possible, they have the energy!). That would mean a rising ball.
I watched this video this morning, and was left with a pretty profound sense of confusion. Primarily, it seemed utterly to fail at answering the basic questions I have about what time is, but also because there was no mention at all of conservation laws.
The message I was left with was "time doesn't flow backwards because it would be extremely improbable for it do do so", which ... really isn't the least bit helpful.
pretty nice video, but the more I learn about the subject, the more convinced I am that the methodology in testing for particles being at multiple places at the same time is flawed.
I would like to find a document of some kind, that would explain in detail the concept of relativistic time and as it relates to other conceptions of time, like the Kantian conception, which held that time does not exist objectively only as a form of the structure of our inner perception as our mind put things in successive order - that is we must put them as such. OK, Einstein revealed that time is objectively outside of our perception, but I still can not fully understand WHAT it actually is!?
A good way is to think of gravity. Gravity is caused by the warping of space-time by the influence of matter. We call it the 'fourth dimension', and it's just like the other three dimensions (length, width, and depth) only we experience it differently.
If time doesn't exist objectively, relativity, and our explanation of gravity disappear with it. It would be like saying 'length doesn't exist objectively".
I heard about some things you mention, of course, and please, do not think that I think that the objectivity of time is still in question, still, the conceptual clarity of the phenomena is still a bit fuzzy, if you know what I mean. When I asked WHAT is time, I meant precisely this: what is time as a separate entity, apart from its effects, what is its carrier, medium, or substance?
Length for example is just our measurement, or assessment of a distance between A and B.
Time is an assessment of a distance from point A and B in the 4th dimension. Time isn't a 'thing' in the sense that proton is a thing. There is no 'particle' of time.
Time is the same as length, and like length, 2 observers in different frames of reference cannot agree on the time.
To put it simply: To answer the question of "What is the carrier, medium, or substance of time", ask yourself "What is the carrier, medium, or substance of space?
The GPS (Global positioning system) uses Einstein's relativity to calculate coordinates. If time doesn't exist, the GPS wouldn't work.
- It works by using the time delay a signal from your reciever has between at least 3 satellites relative to your position. The longer the delay the further you are from that satellite
Problem is that time moves at a slower rate in space than on earth (Because of gravity), so the GPS would be off by quite a bit. Relativity fixes it.
...Perhaps you should elaborate? Presumably, you disagree, so what do you disagree with? Simply calling it stupid does nothing but make people down thumb your post.
Trying to prove the existence of time by an invented association based upon the unlikeliness of the motion of objects and human emotive words is ridiculous. Only the present exists - they said so themselves. If that's the case, time simply becomes a useful concept for a better understanding of the world around us and as perceived by us.
Now. You're looking at now, sir. Everything that happens now, is happening now. What happened to then? We passed then When? Just now. We're at now, now. Go back to then. When? Now I can't. Why? We just missed it. When? Just now. When will then be now? Soon!
Unique. One of a kind. I thank God I exist to know I am here.

The molecules of the ball in fact do posess the energy to overcome gravity and go back up out of the pocket (again, energy lost as heat or friction would have to be collided back to the ball as well). Each instant the ball is falling it gains kinetic energy and loses gravitational potential energy. This kinetic energy could be turned back into potential energy by having the molecules 'randomly' move back up in unison (which is possible, they have the energy!). That would mean a rising ball.

I watched this video this morning, and was left with a pretty profound sense of confusion. Primarily, it seemed utterly to fail at answering the basic questions I have about what time is, but also because there was no mention at all of conservation laws.
The message I was left with was "time doesn't flow backwards because it would be extremely improbable for it do do so", which ... really isn't the least bit helpful.

pretty nice video, but the more I learn about the subject, the more convinced I am that the methodology in testing for particles being at multiple places at the same time is flawed.

I would like to find a document of some kind, that would explain in detail the concept of relativistic time and as it relates to other conceptions of time, like the Kantian conception, which held that time does not exist objectively only as a form of the structure of our inner perception as our mind put things in successive order - that is we must put them as such. OK, Einstein revealed that time is objectively outside of our perception, but I still can not fully understand WHAT it actually is!?

A good way is to think of gravity. Gravity is caused by the warping of space-time by the influence of matter. We call it the 'fourth dimension', and it's just like the other three dimensions (length, width, and depth) only we experience it differently.
If time doesn't exist objectively, relativity, and our explanation of gravity disappear with it. It would be like saying 'length doesn't exist objectively".
TheFifthApes 2 years ago
More correctly; gravity is caused by the influence of mass on space-time. Not only matter has mass.
TheFifthApes 2 years ago
Thanks for you answer.
I heard about some things you mention, of course, and please, do not think that I think that the objectivity of time is still in question, still, the conceptual clarity of the phenomena is still a bit fuzzy, if you know what I mean. When I asked WHAT is time, I meant precisely this: what is time as a separate entity, apart from its effects, what is its carrier, medium, or substance?
Length for example is just our measurement, or assessment of a distance between A and B.
eydos 2 years ago
Same with time.
Time is an assessment of a distance from point A and B in the 4th dimension. Time isn't a 'thing' in the sense that proton is a thing. There is no 'particle' of time.
Time is the same as length, and like length, 2 observers in different frames of reference cannot agree on the time.
Time is a dimension, nothing more.
Have you read A Breif History of Time?
TheFifthApes 2 years ago
To put it simply: To answer the question of "What is the carrier, medium, or substance of time", ask yourself "What is the carrier, medium, or substance of space?
TheFifthApes 2 years ago
Thanks, now you really helped me clarify something up. I was just caught up in a cognitive loop. Thanks.
eydos 2 years ago
My pleasure.
If you're interested, take a look at Brian Cox's documentary "Do You Know What Time it Is?"on BBC Horizon.
(It's available on Youtube)

I'll put it this way
The GPS (Global positioning system) uses Einstein's relativity to calculate coordinates. If time doesn't exist, the GPS wouldn't work.
- It works by using the time delay a signal from your reciever has between at least 3 satellites relative to your position. The longer the delay the further you are from that satellite
Problem is that time moves at a slower rate in space than on earth (Because of gravity), so the GPS would be off by quite a bit. Relativity fixes it.

Trying to prove the existence of time by an invented association based upon the unlikeliness of the motion of objects and human emotive words is ridiculous. Only the present exists - they said so themselves. If that's the case, time simply becomes a useful concept for a better understanding of the world around us and as perceived by us.
