time travel?

Question

are there any articles/books dis-proving einstein about time travel.

please suggest some good readings.
(of course, not funny science fiction but some scientific stuff)

Answer 1

There is one theory that states that if you go faster than the speed of light in the opposite direction of the earth's rotation you will travel in time i don't know if to the future or past, I don't remember the scientist who said this.

Answer 2

Time travel is possible. You're doing it right now. What you are really talking about isn't travel through time, but rather, travel around time.

And that answer would be: Yes. Yes, it is possible, if you could find a wormhole large enough and stable enough to go through. And of course, you'd have to be able to control it. Otherwise you could end anywhere...in any time. This is also assuming travel through a wormhole is even survivable. It may not be.

Yes, it is possible. Almost ANYTHING is possible. But is it likely? Probably not. And given the problems that can arise--like surviving the trip, just for starters--it's best not to try.

Answer 3

Time travel to the future is possible, according to Relativity. And there is experimental proof for that. Of course, at speeds we can travel at, we have only sent humans and clocks billionths of seconds into the future. (We have sent fast-moving subatomic particles further into the future.)
Time travel to the past is not provided for by Einstein's relativity. There is nothing in relativity (not going faster than light, for instance) that says you can go back in time. And going back gets you into logical paradoxes. The most famous one is the "what if you went back and killed your grandfather when he was a kid? Then you wouldn't have been born, so wouldn't have been able to kill your grandfather. So you would have been born, so...(around and around)."
So there are logical proofs against travelling back, but real experimental evidence for travelling forward in time, as predicted by Einstein when you go fast.

Answer 4

There is no scientific information that supports time travel. It's all sci-fi,kind of stuff or lousy science. Just imagine being able to travel in time and getting somewhere before you leave for it....get the idea?

Answer 5

The answer is able to be examined in just a few minutes. It has to do with the physics trilogy: E = mc2, m= E/c2, and c2 = E/m. Notice that in these expressions that the only vlaue that will remain unchanging is that of the c2 one. Energy reduces to E = hf,(electromagnetic energy) and mass reduces to energy. The vaue of c2 is always that of a particular speed, having a particular energy value (likely that of h).

What this means, is that all forms of energy and mass are composed of the "c" value. Because this value is the basis of physical existence, all forms of energy and mass relate to it. The "c2" value describes the basis of our existence, and shows that all events of the present move into becoming our past at the speed of light - this is how long physical reality exists. Further, it states that all that physically exists is present time. There is no past time or future time able to be directly related to present time. Time travel is impossible because the past does not exist as an entity to itself. All those who lived in the past are part of present time, their physical state has changed into gasses and dust. Those of the future aren't put together yet of things found in our present time.

Answer 6

No one has any idea about time travel. Who would have thought that any of the stuff that we have now could exist two hundred years ago? One hundred years ago? Fifty years ago? Some of it even twenty five years ago?

There will be no cut and dried answer about time travel until someone makes it happen. Until then, it will be fun to think about.

Answer 7

Einstein never said that we would ever be able to travel in time.
He only said that time and space will warp as a function of gravity/acceleration or velocity (relative to something else).

Answer 8

A scenario;
You invent a time machine.
You sell a couple for several million dollars to give you travel money.
You go down the street and see ten of them parked at the local bar.
You go back in time and discover scores of them where ever you go.
Time is crowded with them in all eras.
They are a dime a dozen.
That is why time travel is not possible.
