Controversial subject of Time Travel

[ElectrikRipple]

hmm not so sure. If you traveled into the future than u would not be in the sititng in ur lounge or whatever. How could u be sitting there then if u were already in the future because how can u be in the future if u left the present? u cant. And if u got back and waited there for urself u couldnt. we've all heard of the multiverse theory right? well i believe that each "universe" involved in this multiverse is at a different point on the "time line." make since? so if u were to go to the past u would never see urself because there is only one of u in the universe that ur in. does this make since? or am i smoking my lunch? let me know what u think.

first we should think...
our future now is already happened??
if yes...that mean what happen now is sure will happen...
because the ending is already have...
i can't imagine this thing actually
but if our future is uncertainly...
that mean the world is now time travel
because how can we go to the space is uncertainly
u know what i mean??

Don't do that man. It's obvious English isn't his first language, so just ask him to rephrase what he means. Better yet I'll tell you...

He's saying that if our future already happened, then "right now" is already pre-determined because it's already happened in that future reality. Then he says he can't picture that being the case. But now I'm not sure what he's getting at... Newton1, do you mean that if our future is uncertain that we can't travel through time?

I am predicting there will be time travel tonight at 2:00am. Most of the United States will be affected.

 

[newton1]

actually...i say
if the future is unknown
that mean that space and times is still uncertainly
so...how can the time travel go to the uncertainly space time
i think the time travel can do is only review the history

hmm

a. Time does not pass at the speed of light. You need more Einstein. I think it's the Special Theory of Relativity that explains this.

b. G force only applies to places that have gravity. Ever see astronaust eating?

There was an article on the theories of time travel in popular science. Basically, the article explained that if many "what-ifs" were true and wormholes and other things existed, time travel is possible.

But it's a long shot.
