There was a young lady named Bright,
Who could travel much faster than light.
She went traveling one day, in a relative way,
And returned on the previous night.
This poem, well-known to every physics student, represents an implication of being able to exceed the speed of light. Ever since Einstein’s remarkable breakthrough in discovering “relativity” it has been a given in physics that it is impossible for anything to travel faster than light.
It is an easy calculation in relativistic physics to show an object’s mass will increase toward infinity as the object approaches the speed of light. With such a large, increasing mass, no finite force can accelerate the object to the speed of light … or so says today’s physics. [Read more…]
