Can somebody PLEASE tell me why time travel is impossible?

Question

I can prove why, but I want to see what you other people know on the subject.

Here is how. if time travel existed, it would have come back to our time period to give us technology that would ensure that they got even better technology, and if that happened, we would all be The Jetsons.

Answer 1

It isn't. Human kind just hasn't found the answer yet.

Answer 2

One question that is relevant here is whether time travel is permitted by the prevailing laws of nature. This is presumably a matter of empirical science (or perhaps the correct philosophical interpretation of our best theories from the empirical sciences). But a further question, and one that falls squarely under the heading of philosophy, is whether time travel is permitted by the laws of logic and metaphysics. For it has been argued that various absurdities follow from the supposition that time travel is (logically and metaphysically) possible. Here is an example of such an argument;

(1) If you could travel back in time, then you could kill your grandfather before your father was ever conceived. (For what's to stop you from bringing a gun with you and simply shooting him?)
(2) It's not the case that you could kill your grandfather before your father was ever conceived. (Because if you did, then you would ensure that you never existed, and that is not something that you could ensure.)
(3) You cannot travel back in time.

Another argument that might be raised against the possibility of time travel depends on the claim that Presentism is true. For if Presentism is true, then neither past nor future objects exist. And in that case, it is hard to see how anyone could travel to the past or the future.
Despite the existence of these and other arguments against the possibility of time travel, there may also be problems associated with the claim that time travel is not possible. For one thing, many scientists and philosophers believe that the actual laws of physics are in fact compatible with time travel. And for another thing, we often think about time travel stories; but it is very plausible to think that a story cannot depict things that are downright impossible. For example, it is natural to think that there could not be a story in which two plus two are five, or in which there is a sphere that both is and is not red all over. (This seems especially true if the story is told pictorially, as in the case of a movie.) Hence, if time travel is impossible, then we should not even be able to consider any story in which time travel occurs. And yet we do so all the time.

One task facing the philosopher, namely you, who claims that time travel is impossible, then, is to explain the existence of a huge number of well-known stories that appear to be specifically about time travel.

Answer 3

Because it is sufficiently complicated that it is far from satisfactorily under control.
An example of getting into something terribly advanced and not enough under control was depicted in the movie THE PHILADELPHIA EXPERIMENT. It was an unforgettable and horrifying example of something too advanced going wrong when they tried it...........plus there were all too true connections to its having been based on fact....and that the awful things seen in the movie were part of the worst that happened. In the movie the ship was supposed to magically move from one condition to another and one place to another. Instead, men on the ship were horribly cought with their bodies in part being one with and part of the deck and no one knew how to extricate them or how to solve the horrible situation.

Now you know why time travel is impossible. It is impossible to do it and do it safely. And go and get back.

Time travel......What if it were possible to get out there and impossible to get back? What if you could leave here and not get there? Be in limbo?

Answer 4

Assuming the mass of total existence is a constant, time travel would imply two possibilities which would contradict that constancy: the duplicity for mass as you meet yourself in the past or the future and your absence from proper time extant position.

An other reason is there is no good reason for time travel; your complication into your own life as you attempt to avoid time paradoxes or uncertainties and realities' potential to eliminate your threat to time integrity.

Answer 5

• It would take an infinite amount of energy; equivalent the mass of the universe.
• Quantum mechanics cannot combine with special relativity.
• Even to transmit a signal (not matter) through time would suggests a violation of the causality of time. (Can't be in two places at once.)
Basically have to simultaneously deconstruct all the known principles of mass, time, and motion; the laws of the universe.

Answer 6

Scientifically it is not. If people can make shuttle or something of the sort to withstand going the speed of light, then that person would be possibly able to travel into the future. However though, that person, once he has gotten to the future would not be able to get the time he'd lost back, therefore he would never get to see his children grow, his friends would never be his age again, and events that he would have liked to see, he would not.

Answer 7

It is only impossible because we have accepted as a collective society the illusionary limitations of space and time.

Answer 8

Time travel is IMPOSSIBLE because time is a tangible matter. It cannot be real matter as in the concept of time travel.

Answer 9

Time does not exist. It is an illusion. We are all energy emanating from our source. We are not separate from our source. We are source. There is no past or future, there is only now, this instant, forever.

Answer 10

That's all we do, space-time travel!0!

Answer 11

according to einsteins theory we, or the vehicale we are travelling in would have to be infintely long to be able to reach teh speed of light
