I feel flat now.
It starts talking nonsense at the 5th dimension. :p
I had a tiny little lol at Flatlanders.
Obviously he was wrong about the 2nd dimension flatlander's part, because Paper Mario isn't split into two by his oesophagus.
Nice video :)
Didn't we establish/proven already that time travel is impossible?
However if this theory is correct then space travel would be possible. You don't have to go faster than the speed of light, you could just fold the space/time continuum and travel instantly to the other point.
Only hope is, we won't meet hell like in the movey event horizon =p.
Time travel is possible into the future. However, you can't go back in time farther then where you started from when traveling into the future. And of course, the sheer amount of power that would be needed to open the wormhole, make sure its at the right spots, and open it wide enough and for long enough to pass through and come back later are astronomical, and beyond our tech right now. Also, yes, this stuff is mostly correct, it stems from string theory, which is mathematically completely proven, but still untested experimentally due to us lacking the tech to do so. However, it is the new supercollider in Switzerland that could yield the first proofs. See, string theory says there are 11 dimensions, and gravitons, the particles that create gravity, are multidimensional in their ability to affect matter, but single dimensional in where they reside. It is believed that by using the LHC, we can pull those particles into our demijohns, at least temporarily, long enough to see them. If we can do this, it is a MAJOR proof of string theory.
Check out the book and documentary "The Elegant Universe" and the sequel to the book "The Fabric of the Cosmos."
Here's a better visualization:
Each of those points would actually be on every single point, which are infinite, of course. Curled up into each point are the extra dimensions, in which other particles, gravitons included, reside. We pass through these dimensions every day, every time we move, but we don't actually feel it, as they are so minuscule.
