How much energy is there? And why is the sum positive (if it is)? What is going on?

The OBSERVABLE mass/energy of the universe is 3 times 10^52 kg. There is more (at least several times more) energy than that that we notice gravitationally, but can't quite see. But that gives you a ballpark figure. Multiply that mass by c = 3x10^8 if you want energy in joules.

E=mc^2
Thus the total energy content of the universe is dependant on the sum of all masses existing in the Universe. We could call this infinite, though I am sure some physicists have put an estimate on it.
What is going on? Well, energy cannot be created, nor can it be destroyed (conservation of energy law). Energy is, however, constantly being converted from one form to another (heat, mass, speed, etc).

Its is unmeasurable. The energy of the sun alone is already so much to be able to survive millions and millions of years. Want to calculate the energy content of the UNIVERSE? You must be crazy.
