I truly hope not, if we were to be able to look to the future and avoid mistakes that would be allright, but should we go back and change the slightest thing wouldnt everything be different? and not neccesarilly for the good. Also life can be hard sometimes and what if you were to look forward and see your self alone and a failure, your entire life wouldnt be like that but the end result would leave you utterly deppressed.
Yea it took until the what..Mid 1900's (Correct me if Im wrong, I know nothing much about that type of stuff cause I never pay attention in class) for someone just to get to the surface of the moon, and no telling what inventions will come about near the end of the 2000's if the world is still here.
If we can build a craft that would travle at light speed we will be able to travle back in time (on of instines thorys) but it is physicaly impossable for anything besides light to travel at such speeds hence the name.
I also bilife that traveling even 1 second back in time would create a paradox destroying time its self.
If it would be possible to travel back in time – some day in the future – WHERE are the tourists from the future??
So, as the good Stephen Hawking said, the fact that we’re not knee-deep in time-travel tourists is empirical evidence against travelling back in time. It doesn’t matter if the time-machine gets invented tomorrow, in 100, 1000, or a million years from now. Once it’s invented people should be able to travel back to us – to 2004 – from their time. We don’t see anyone.
150 years ago it was technologically impossible to travel to the moon. But that is not the same as it being physically impossible.
There’s light-years between technologically and physically impossible.
It’s physically possible to travel into the future. That’s just good old Albert Einstein’s special theory of relativity. If we start moving near the speed of light (300.000 km/s), there’s such a thing as time-dilation, which will propel us into the future of those not travelling at such high speeds.
But it doesn’t seem possible to find a way of travelling back in time.
i agree with hawlkings, Einstine did figure a way of traveling back in time (something to do wil flying a craft at light speed round the eart) but he also proved light speed was imposable, the whole idea of a craft traveling at light speed is foolish as humans black out at forces of 6 g's so what in hells name is light speed gonna do to us?
Filth> What Einstein did was using the time-dilation in his equations. Should something massive (as opposed to light which is mass-less) hypothetically reach the speed of light time would stop relative to everything else, and if this massive body could travel faster it should – hypothetically travel back in time.
But as you say – nothing massive can travel at or faster than the speed of light.
If you accelerate slowly in space it could be an achievable speed – in theory. No one says you have to hit the speeder THAT hard. 🙂
