Now teleportation…
Wormholes!!
Also, time travel forward is only theoretically possibly in the sense that time would pass at a different rate near a black hole. So if we ever develop technology capable of breaking away from the gravity of a black hole we could travel some petty number of years into Earth's future. So even for forward time travel we need to figure out first how to break the laws of physics.

Or approach the speed of light. We can't reach the speed of light ever, of course, but if we traveled at say, even 0.5c the effect would be significant.

We are all traveling forward in time....

Actually, technically, time is an illusion. I will however rephrase: In order to travel forward in time relative to natural progression, we need to figure out first how to break the laws of physics.

All about the momentum, baby. Although, realistically, in order for the difference in time to be significant we would have to orbit. Pretty sure we would have to break the speed of light to break the orbit of a black hole.

Actually, we can. Special relativity.

Special relativity is the reason why we can't reach light speed. Although space and time are distorted in situations where light speed would otherwise be breached, I'm not sure it's possible to accelerate anything of significant mass to a speed close enough.

I thought it was special relativity, but I was talking about how you age slower when you travel close to light speed.
Which is, in a sense, forward time travel
RE: Last post wins. - baustin42 - 10-11-2014 01:38 AM
Yes, time will dilate at a speed significantly close to the speed of light. I'm just saying I don't think it's possible for humans to travel at that speed.
