If you wish to introduce new terms, you should define them.
Null is hardly a new term. I see the
dictionary.com defines it as zero. This is incorrect. Null is the same as doesn't exist. This is what everything consisted of before anything ever was, so you can argue till the cows come home how the total force of the universe nears zero, but thats not the issue at hand.
I said nothing about force. I said the total energy (that includes masses, fields, etc.) is zero. You originally asked where "all that energy" came from. There isn't "all that energy" there. There's only a total of zero.
