Hey guys :). Here's something I've been wondering for a while now.

So we know E=MC2 is wrong because there are galaxy's out there that don't meet these standards.


The atomic bomb uses the equation E=MC2. Because if energy=mass and backwards mass=energy so we release energy inside an atom.

So how come there are galaxies out there that don't meet these standards, one of them is wrong. Anyone happen to know why?
