Accelerated Motion and Gravity Equivalence

It seems a principal of Einstein’s General Theory of Relativity that there is an equivalence between accelerated motion and being in a gravitational field.  It seems that an observer would have no way to tell the difference between these two states.  However, the gravitational force being mediated by elementary force carrying particles (gluons I think), [...]

The idea is that, if there is a particle which travels with a speed less than the speed of light, it will never cross the speed of light. But if there are some partricles ...Read the full post
