the astrologers found and traced gamma rays with red shift and found an explosion so powerful its unimaginable. and does the impossible at first it breaks the E=MC2 law.

If it's 'astrologers', then I wouldn't pay attention to what they say at all. :rotfl: Edit: Damn! Someone beat me to it!
By the way, gamma rays are photons, so E=mc^2 doesn't apply to them. Photons do not have any mass, and E=mc^2 only gives the rest mass of a particle. If you want the energy of a moving particle, you need to use E=sqrt(m^2c^4+p^2c^2) where p is the relativistic momentum of a particle (for a photon this is h/wavelegnth where h is Plank's constant).

Well, E=mc^2 is a result of relativity. Einstein's only starting points in special relativity were, 'The speed of light is the same for all observers' and 'the laws of physics are the same for all observers'.
Einstein definitely made some major mistakes, but relativity is not one of them. Relativity is certainly correct, and lots of people say its one of the two pillars of modern physics.
This looks like a good link if you are interested in special relativity:
