Will time travel ever be a reality?

Question

If it is then wouldn't there be people among us from the future?

Answer 1

Actually, time travel is possible, but only in one direction...forwards, at a rate of 60 minutes per hour.  Backward travel in time cannot be possible for a number of reasons,  the biggest of which is it's violation of causality.  Everybody is familiar with the Grandfather paradox, so I won't go into it here, but it is itself an exceedingly powerful argument.  There are a lot of misconceptions regarding time travel and Relativity.  Relativity does NOT say that backwards time travel is possible.  It merely says the math works just as well if time was in reverse, which is a very different thing indeed!  Try it for yourself, though you'll need a pretty big chalk board!

Answer 2

I don't think time travel will ever be a possibility because if it would be than where are all the travelers?

Answer 3

Just because we don't have time travellers going on tv to broadcast their presence to the world, doesn't mean that they're not here!! First of all, they would invariably be dimissed as nutcases. Secondly, time travel is not something you would take lightly, light a jaunt in the countryside. You would need to be aware of the dangers of interfering with history. A serious time traveller would want to be in cognito. Besides, how could you tell a time traveller from a present dayer?  

Answer 4

the world may never know!  

Answer 5

Oh man, you just divided by zero. Anyhow time travel is one of the most messed up things you can begin to talk about. I could type all day and not evan begin to brush the surface of the most simplistic of  time travel theories.

One thing we know is that the faster you go, the slower time goes. This was proven by syncronizing two atomic clocks and putting one on a fast orbit satalite for some time. The clock on the satalite did indeed have an earlier time. I really don't know the specifics of this expiriment.

One interesting thing to think about is that the light we see from distant stars is not what is happining on those stars right now. Some of the stars in the night time sky are millions of light years away. These stars may have already collapsed or went supernova long ago, however we see them as they were millions of years ago. That being said, if we could travel faster than light in away from the earth and say we were to catch up with the light from April 1861 we could look back and see the American civil war starting on earth.

Another thing to think about is that wile space is commonly though of as 3 dimensions, back and fourth, left and right, and up and down. There are really 4 dimensions, the fourth being time. This may not make be easy to understand, but if you think about it as, say a meeting place. If you have the directions to the place, you know the 3 dimensional location. However it is all usless if you do not know the time of the meeting. So the meeting takes place in " space time " you need both pieces for them to be relivant.

Answer 6

Why not?  Our minds limit us much more than our reality.

Answer 7

Well, here something we can DO about it:

Ask people around for how possible you think this is. Please, an open-mind.

Answer 8

Who says ...History doesn't repeat itself...?

Answer 9

according to Green's String Theory about the manifestation of the universe we will in a way.  Only based on his theory, we will be traveling by going through dimemsions rather than having to deal with traveling using the slow method of traveling by the use of the speed of light.

Answer 10

I think so... i think it will happen. I really hope so!!!! :) Do you watch Doctor Who? A bit geekish, but really interesting. I started thinking, maybe we are not alone....Sometimes you have dreams of the future, things like that. Who says its not real?????
