      According to Einstein, if you were to approach the speed of light you’d get infinitely massive! This is impossible which is why Einstein said that the speed of light was something that only mass-less entities (such a photons ‘energy’) could travel at.

      think of mass and energy as sort of the same thing so you can switch between one and the other using E=mc^2 but because c is so big that means a little bit of mass (m) gives you LOTS of energy. Thats how some bombs work.
