Creating universes from nothing

I think I will discourse a little on conservation of matter/energy. This is a principle that was only discovered in the nineteenth century, and it was discovered empirically, using induction, not by deduction. Maybe that is why God didn't include it in the Ten Commandments.

Now, it is for sure that when someone looks at the output of a particle collision, and finds the output doesn't total the input, then there is assumed something wrong. Matter/energy is so almost always conserved that the assumption is always that that is the case. This was in fact how neutrinos were predicted, and later found.

However, quantum uncertainty makes it a certainty (now I like that -- uncertainty makes a certainty [grin]) that so-called "virtual" particles pop into and out of existence all the time. This is a misnomer -- while they exist they are real and have demonstrable effects. It is in fact this creation of particles at the event horizon of a black hole that caused the scientific community to realize they eventually evaporate.

What you do, when you want to make a universe, is you make it from nothing. The universe is "the greatest possible free lunch." There is good reason from observation, and excellent reason from theory, to say that all the conserved quantities (mass/energy -- gravitational charge --, electric charge, momentum and angular momentum) when taken for the universe as a whole total nothing. Positive gravitational energy is balanced by negative ("mostly dark") energy, electrons balance locally (positive and negative charge), motion is essentially in all directions, and the cosmos is not observed to rotate. 

However, to get a universe you need do nothing but wait. Quantum uncertainty will see to it that it will happen now and then.

I have posted my understanding of this as best I can: those with knowledge of the area are welcome to nitpick at any mistakes.
