If the total energy of the universe must always remain zero, and it costs energy to create a body, how can a whole universe be created from nothing?
We get the exciting result that the total energy of the universe is zero. Why this should be so is one of the great mysteries - and therefore one of the important questions of physics. After all, what would be the use of studying physics if the mysteries were not the most important things to investigate?
A state of negative energy means that you are essentially getting something for nothing.
Science has proved that everything is energy, and now they have dark energy, dark matter. They don't call it all-embracing consciousness; they call it dark because they can't measure it. You know, paint it black.
If you have nothing in quantum mechanics, you will always have something.
Empty space is a boiling, bubbling brew of virtual particles that pop in and out of existence in a time scale so short that you can't even measure them.
Theoretical and experimental physicists are now studying nothing at all-the vacuum. But that nothingness contains all of being.
Bose-Einstein condensation is one of the most intriguing phenomena predicted by quantum statistical mechanics.
