There's no known way to transfer information faster than the speed of light (and if there were, there are some relativistic tricks you can play to actually send information backwards in time).
- bsk 16y agoInteresting, what are those tricks?
- panic 16y agoI can't find the article I was thinking of, but http://sheol.org/throopw/tachyon-pistols.html http://sheol.org/throopw/tachyon-pistols.html gives the general idea.

- philh 16y agoI interpret his statement as meaning "we could use quantum entanglement to transmit information at c (or c minus epsilon) instead of .66c". But (as far as I understand) quantum entanglement doesn't let you transmit information at any particular speed, so that still doesn't work. (Roughly speaking, QE can be thought of as "the universe transmits information at >c", but in order to extract this information, we have to send messages conventionally. So it has a theoretical upper bound of c, like everything else, but has the same practical limits.)
