Get two flashlights and tape them bottom to bottom. Turn both on. Beams of light are now traveling at twice the speed of light away from each other.
“Beams of light are now traveling at twice the speed of light away from each other.”
Ah, but here is the catch: from what reference frame would you observe that? Without designating a reference frame, you cannot test the predictions of relativity properly.
No, because time will slow down so that no matter how you try to observe and measure them, they will be traveling apart at 1X the speed of light only.
