We believe that energy does not get lost.

It is therefore impossible to say that energy came from nothing (or nothingness) because one cannot speak two truths that fully contradict one another. Either energy came from nothing, or energy does not get lost. There is no wanting our cake here and getting away with eating it two times.

That people hold on to bad ideas must be because the brain has two hemispheres and people may forget what they accepted with one side of the brain and subsequently accept something on the other side that conflicts with that. And then they try to make it (w)hole.

Matter came from energy, even the smallest child knows that (or should know that), and it is the biggest surprise in my life that the smartest folks don't see that simple truth how not to speak out of two sides of one's mouth.

Because energy does not get lost, there are therefore two realities in our current universe.

Yes, nothing played a very important role, but it was the nothing of a fundamental separation occurring among original energy that made matter possible.

Energy does not get lost, and we call that a closed system. But there is no conflict with any law when the universe is proposed to have two closed systems.

The book includes evidence of a mathematical nature that the building blocks of math contain a zero with a universal function and that no other number portrays that function. A fundamental separation occurred before matter came into being.
