Question regarding Einstein's E=mc2 formula and light
Dear answerbank,
I would like to know if it is possible for 1 ray of light in air to catch up against another ray of light in vacuum that was released 1 second before the first ray of light and also, whether as according to to Einstein's formula E=mc2, does it show that 1 gram of Uranium have the same amount of energy as 1 gram of water.
Thankyou very much for your time.
