Do you think that People will ever be able to time-travel?

Question

And if so.. make a prediction? This generation?

Answer 1

Everyone thinks if you travel faster than the speed of light, you can time travel. However, Einstein said nothing could travel faster than light. But we know that both are wrong. There are two ways that could be possibilities of time travel, and neither can be physically done by humans, and if done naturally, would instantaneously lead to death.

1. black hole... obviously.

2. travel faster than the speed of information between particles, (which is truly the fastest possible thing existing)

1. cannot be made by man, and if we were sucked into a black hole, we would probably be separated into individual atoms.

2. not possible. at all.

Answer 2

Doubtful.  And certainly not in the H.G. Wells sense of getting into a time machine and setting the controls for some past or future time.  The reason is simple, time (or history) is not a place.  There is no "there" to go to.  The past is in each person's mind, but there is no "collective past" that some time traveller could go to as if the past were some kind of universal history book. And since the future doesn't exist, again, there is no place to go to.

Answer 3

Yes, yes they will.

Answer 4

Usual answer - forward in time, easy, been doing it since life started

backwards - no - too many high energy engineering problems

Answer 5

There are suggestions from physics that a time machine is possible.  However, you can only travel back in time to the point that the machine was built.  Also, it is technically really difficult, involving manipulating at least stellar masses.  Also, some of the materials required may not exist in principal, making it impossible.

My current best guess: no.

Traveling into the future is easy.  We're doing it now.  Pack your toothbrush, it's a one way trip.

Answer 6

No. The question is equivalent to asking if we can ever go back in temperature.

The simple explanation is that unlike the three spatial dimensions which are vector, time (like temperature) is scalar. This means that there is no direction associated with it. It can speed up or slow down relative to a given reference frame, but it can't "go" in a direction.

Answer 7

It is theoretically possible.

Answer 8

We are all travelling forward in time at the rate of 60 minutes per hour.

Answer 9

If we did, everything would change and we could just toss the laws of physics right out the window. We won't, don't worry.

Answer 10

No, never.

Answer 11

No, for two reasons.

1)  It violates the laws of physics as we understand them, and we don't have anything else indicating we are that wrong.

2)  If people could time-travel at any point in the future, they would have come back and we'd know about it.  The fact that we've never had any time travelers is a very good indication that we never will.
