By the way, could someone give me a synopsis of the video from the first post? My computer's too slow to watch it and I feel a bit uninformed right now.
Basically a scientist is trying to create a 'time telephone'. The idea is not to travel through time, but rather, to create a machine that would create a informational passage to the future.
It would only work from the moment it is initially turned on however, so if it were turned on in say, May 13th 2001, you wouldn't be able to access May 12th 2001. It's also conceivable as soon as it is turned on a deluge of messages from the future would be immediately intercepted as they would've been sent backwards into the informational passage some time in the future.
The premise is explained through the use of coffee. If you stir coffee, then put a single coffee bean into the swirling coffee, it will continue to spin because the coffee is still moving. The bean itself isn't moving, but it's being propelled by the coffee.
The idea is essentially that premise, with particles instead of coffee beans and space instead of coffee. It would be like creating something akin to a black hole to make the particle travel faster than light to allow it to time travel in some fashion.
I don't really get how the methodology works, and I don't get the science, and to be honest, I don't much care. However, the concept of a 'time telephone' sounds like a plausible way for time travel to occur, and is quite an interesting concept in itself, regardless of the science used to justify the idea.
