so why time recall woud be imposible?is it necesary to reach light speed to travel in time?
I mean can we make a wormhole here on earth?

>>	Anonymous Wed Apr 20 12:05:51 2011 No.2918656 a wormhole on earth would be catastrophic, a safe distance would be a wormhole near pluto also if i'm not wrong the amount of energy needed to open open a wormhole is almost impossible to obtain

Time dilates when you go faster but thats due to the interplay between space, the speed of light and time.

Plus you can never reach the speed of light even with all the energy in the universe.

Going backwards is just infeasible.

Time doesn't really exist, its just our perception of change.

>>	deleted Wed Apr 20 12:15:51 2011 No.2918696 >>2918685 so this is why time exists?so if we stop moving we coud stop time or recall it?

>>	Anonymous Wed Apr 20 12:17:51 2011 No.2918706 >>2918696 No, you would experience time at the same rate you are now. But to a moving observer you would appear to age quicker.

>>	Anonymous Wed Apr 20 12:18:51 2011 No.2918711 >>2918685 Space can move faster than the speed of light, since its not really a thing with mass. Space has no past, present or future. So it can go as fast as it goddam likes.

Its more feasible to travel to an alternate universe which is identical to ours but farther back in time than it would be to travel backwards in time.

Time is like a line which we are on that we can only move in one direction. however, if there are multiple universes, then at any point in time new universes are being created with different outcomes. if we could somehow travel to an alternate universe, it would be like going back in time.

but like what everyone else has been saying, wormholes are very unstable and small. You'd need a lot of energy to open one and keep it stable. And then, how would you get back to this universe? You'd have to hope you traveled to a universe where cross-universe travel is normal...
