[QUOTE="James Snover, post: 16605249, member: 67454"] What is space? Why is time tied to it, so that Einstein called it spacetime? Einstein created the best theories ( so far) of the universe at the "macro" level, I.e., the one of one in which we live, with his theories of Special Relativity (special, because it did not include gravity), and General Relativity (general, because it did include gravity in it's scope.) it took the old boy over ten years to figure gravity into the big picture. Incredibly successful, but while they explain spacetime and gravity, they do not explain what either one is. But he wasn't done there. Uncle Al also started the framework on quantum mechanics, the study of the sub-atomic realm of the atom. Uncovered a whole bunch of strange things he couldn't even begin to explain. It worked, but he hated it. But it worked, so he continued to develop it. Fast forward a hundred years or so, and: We think spacetime may come in discreet quanta, like elementary particles. We think entanglement and wormholes may act to combine to create what we think of as spacetime. In the same way that individual molecules of water do not act anything like bodies of water. Maybe. For further reading, look up "It From Qubit." Sent from my iPad using the [URL='http://r.tapatalk.com/byo?rid=92568']svtperformance.com mobile app[/URL] [/QUOTE]
