is time travel possible?

Question

it seems that if we were to ever discover time travel in the future we would know by now bc they would have come back and told us

Answer 1

Actually, the current theory on time travel is that the furthest back into the past you can travel with a time machine is to the point that the time machine was created.

According to this theory, to travel back into the past, you would need to create two worm holes. One wormhole would exist at the time that you turn on the machine and the other worm hole would be put somewhere to 'age'. At some time in the future, something could be put into the wormhole in the future and it would come out in the past.

Answer 2

I had this conversation with my friend like a month ago. We were talking about the technological advances society has made in the last 100 years or so. Just look at the internet and the world of electronics. It was unimaginable 100 years ago to conceive of the world that we live in today. So, just picture the world 100 or 500 years from now. There would be so much crazy s*** going on and someone might invent time travel in the future. Anything is possible. A good movie I recommend to watch is Donnie Darko. It talks about time travel and also it's a kickass movie.

Answer 3

Yes, it is possible. Stand in one place for five seconds, and you are now five seconds into the future from before.

You think it would be as easy as telling us they can go back in time, but you have to think about what affect that may cause.
There are a lot of unknowns about what can happen if someone goes back in time and has any affect on the past. This would be my guess as to why they don't tell us.
Go read Ray Bradbury's "The Sound of Thunder". It is a short story that gives an idea of what might possibly happen if we were able to time travel and change the past.

Answer 4

Albert Einstein theorized that it is possible to travel forward based upon relativity and a few other theories. Basically, time is relative to us on Earth. He theorized that if it is possible to travel faster than the speed of light, that upon your return to our point of departure, you would have been travelling for a longer amount of time then you actually did relative to Earth. In other words, you would only age one day, but your family might age for several. There have been some pretty interesting studies on this, especially involving black holes, worm holes and some theories called "Einstein Rosenbridge"... However, no one has every theorized how to travel back in time and it is therefore believed that based upon the current understand of physics and the space-time continuim (einstein's 4th dimension) that this is not possible.

Answer 5

Today, we know that time travel need not be confined to myths, science fiction, Hollywood movies, or even speculation by theoretical physicists. Time travel is possible. For example, an object traveling at high speeds ages more slowly than a stationary object. This means that if you were to travel into outer space and return, moving close to light speed, you could travel thousands of years into the Earth's future.
Newton's most important contribution to science was his mathematical definition of how motion changes with time. He showed that the force causing apples to fall is the same force that drives planetary motions and produces tides. However, Newton was puzzled by the fact that gravity seemed to operate instantaneously at a distance. He admitted he could only describe it without understanding how it worked. Not until Einstein's general theory of relativity was gravity changed from a "force" to the movement of matter along the shortest space in a curved spacetime. The Sun bends spacetime, and spacetime tells planets how to move. For Newton, both space and time were absolute. Space was a fixed, infinite, unmoving metric against which absolute motions could be measured. Newton also believed the universe was pervaded by a single absolute time that could be symbolized by an imaginary clock off somewhere in space. Einstein changed all this with his relativity theories, and once wrote, "Newton, forgive me."
Einstein's first major contribution to the study of time occurred when he revolutionized physics with his "special theory of relativity" by showing how time changes with motion. Today, scientists do not see problems of time or motion as "absolute" with a single correct answer. Because time is relative to the speed one is traveling at, there can never be a clock at the center of the universe to which everyone can set their watches. Your entire life is the blink of an eye to an alien traveling close to the speed of light. Today, Newtonian mechanics have become a special case within Einstein's theory of relativity. Einstein's relativity will eventually become a subset of a new science more comprehensive in its description of the fabric of our universe. (The word "relativity" derives from the fact that the appearance of the world depends on our state of motion; it is "relative.")

Answer 6

Time is just a measurement like a inch or a gallon. You can't travel a cup can you? Maybe if we search space for a way to move around faster or slower than we would have moved apart from it it might be possible. Humans won't invent a way to do it though.

Answer 7

We do it every day we go from one minute to the next but if you mean go back in time or foward

Think on these is time real? Does it flow in one direction only? Does it have a beginning or an end? What is eternity? None of these questions can be answered to scientists' satisfaction

Answer 8

Time is a human created illusion to make events linear, because our way of thinking is linear. Now is the only moment, hisoty is all happening within the same moment.

No such thing as time, so how can time travel be possible if it doesn't exist?

Think about it.

Answer 9

Sort of. It is impossible to travel backward in time, unfortunately. But what you can do is slow time down for yourself by going at speeds near the speed of light. If one twin traveled fast and one didn't, later on if they met up the one that traveled faster would be slightly younger. Sorry to disappoint. :(

Answer 10

Yes, I think it is possible. I just don't think anyone has come up with the formula to do so yet, that's all. But I'm sure that with time, they WILL discover it.
