Thread: the energy of the universe

If gravity and the explosive force of a star balance each other out, and the protons and electrons within thier matter also cancel out each others charges, and that any excess energy given off by quantum fluctuations is thrown off into space in the form of radiation, then surely the total amount of energy the star will have at any given time is 0.

Then at any given time that star will not be a star. I believe such a star is called void. Anoid the void. :-D

Just kidding.

Are you implying that everything came from the void and so must net out to zero in total.

My thinking is that energy has always existed, and so will always be present in one form or another.

Do you want to tell me why you think there was ever "void"?

I have written the Axioms of my view of the universe. The first axiom is, "If at first there was nothing, nothing could ever be".

Electrons and protons do not cancel each other out. They 'balance' electrically the NET charge of the Atom.

THink of it as like a 'tug of war' the tension on the rope does not cancel, it is very much there, the NET result of balanced teams is no movement. but the teams are still there.

To 'cancel' suggests they both dissappear.

Similar remark for the stars, the forces balance until the hydrogen is mostly converted then [if the star is large enough] it will 'explode'

massive stars can fuse elements all the way up to iron before undergoing supernova.
