This video pretty much sums it up. There’s energy in empty space. Zero point and other types of energy exist too.
It’s all based on Quantum Physics. Some strange and wonderful things have come out of that field of study. It has pretty much exposed the innards of the universe.
And the video talks about vacuum energy, the Casimir effect etc. Really fascinating stuff. And it has the added benefit of being one more piece of evidence for the fact that no gods have ever existed.
Spewing Truth in the face of Lies 
That is really rather interesting, something I wish I understood more about. What would occur if something did reach absolute zero? Would it in a sense “cease to exist” because it wouldn’t be able to be detected by any equipment? Is space-time a substance, or some phenomena? What do you think? Also, what do you think about his interpretation of Quantum Mechanics( that is in essence what it is, correct?)? Should we take literally what our measurements are showing? Like that electrons exist as some ontological blur, or that it is simply a limitation of our equipment?
