For reference, light takes about 1ns to travel the length of your brain, so that's 20,000,000 times faster than thought. Much, much slower. Connections between neurons can be fast, using electrical signals, but still take 0.2 ms to transmit.

Most of us already know that darkness is the absence of light, and that light travelsat the fastest speed possible for a physical object. So, what does this mean? In short, it means that, the moment that light leaves, darkness returns. In this respect,darkness has the same speed as light.
Some people interpret this mathematical limit to mean that light, which obviously moves at the speed of light, experiences no time because time is frozen. But this interpretation is wrong. This limiting behavior simply tells us that there is no valid reference frame at the speed of light.
While researchers have never found a wormhole in our universe, scientists often see wormholes described in the solutions to important physics equations. Most prominently, the solutions to the equations behind Einstein's theory of space-time and general relativity include wormholes.
