Wow, wormholes all around us? Gotta make ourselves very small.

Broken the speed of light,...

It's only a matter of "time" :-)

Einstein's equations are a snapshot of what we understood at that "time". To think that is the end all and be all is to assume we are far smarter than we really are.

Being able to travel faster than the speed of light would lead to a wide variety of bizarre consequences.

For instance, an astronaut moving faster than it would theoretically arrive at a destination before leaving.


The above sentences from the article are rather silly. Perhaps an example will clarify. Light energy takes about 8 minutes to travel from the surface of the sun to the earth. An astronaut travelling from the sun to the earth at twice the speed of light would get to the earth in 4 minutes (how he would slow down to drop in to say hello is another "matter",...I kill me with all these puns :-)

It would be better to say that we sitting on the earth would see the astronaut appear before us, before the light energy showing him leaving the sun would be seen by us. Einstein's equations and theory couldn't deal with matter travelling faster than energy, but nothing out there says matter and energy and time and the universe can't.
