How plausible do you think the concept of time travel is?

Question

Namely, going back in time.

Answer 1

Not at all plausible.

I've read SciFi for years and no longer read those with time travel elements. They are so illogical as is time travel. If you go back and change anything, how will you know to go back a change it when the present time arrives again? Then things change because you didn't go back and change what you changed and...well, you get the picture.

Of all the things scientist (who read SciFi) have worked on due to inspiration, time travel is the one thing furtherest from any kind of realization.

It is a pipe dream.

Answer 2

hmm.. I believe for us to travel back in time is impossible.

Consider the grandmother paradox: you go back in time, kill your grandmother(before she had your mother), you were never born..so how are you able to exist??

The only way this makes sense is if there are different dimensions of reality.

i.e. Consider one thing you could do right now.
You could get off the computer.

In one reality, you do.
In another, you don't.

The one you are conscience of depends on the decisions you make.. of course that makes for an ininite amount of realities.



But, here is something to think about. Consider time to be part of our physical dimension.
So we have
0 dimensions : a point (no travel)
1 dimension: a line (travel left and right)
2 dimensins: a plane ( travel up, down, left, right)
3 dimensions: a cube [or sphere] (travel in any direction)
4 dimensions: a cube in time ( travel to any destination at any point in time)

Consider the evolution of life.
By the time we came around, we could travel in 2 dimensions... but we couldn't go too far up (unless climbing a mountain) or too far down (we wouldn't survive at great depths under water)

Now, we have the technology to travel to the moon and the great depths of the ocean.. maybe, we could overcome the limits of time as well..

It's interesting to think of the possibility...

So: my final answer... not very plausible..
The only way I can see something like this happening is a virtual reality capturing the events of the past, and traveling that way. You would not affect the actual events. But in order to have a system like that, we would need a lot more knowledge of the past.

Answer 3

I guess when you start messing around with the atomic makeup of an object you never know what may happen. As a normal person with no scientific background, it sounds outlandish to me but who's to say? An interesting thing for you to google: The Philadelphia Experiment and Alfred Bielek
Some claim time travel already happened in 1946...

Answer 4

No matter what the professionals say, it IS impossible. There is just TOO much damage that could be done. If time travel was possible, travelers from the future, who undoubtedly would be much more intelligent than we are, would have already come back and fixed things (or messed things up - depending on how you look at it...)

Answer 5

Not at all.... Just use logic. If you could do that, you could be somewhere before you left to go there. Plus by now, if such a device existed in the future, I'm sure we would have been visited at least by people buying tons of lottery tickets.

Answer 6

Not likely we'll see it in our time. LOL no pun intended, but maybe couple hundred yrs. from now. You have to figure out a way to cross the time continuem(spelling?) and also transport molecules to such and back safely. More high tech than we are capable of in this day and age. I wish I could see it though, would be neat.

Answer 7

Don't mess with it. The Temproal police will be on you before you could do anything any way. Besides Time paradoxes give me a headache. It is not worth thinking about.

Answer 8

Depends on whether you know exactly where the "Big Bang" happened. You go back in time when you go toward the center and forward by going away from it.

The Aliens that visit us here know.

Answer 9

If time travel is possible then it has already happened.
