@MSH: Does infinitely small mean anything to you? It does to me, it means so small that, essentially, it doesn't exist. And there's no way that you could even fit one person into an infinitely small point, never mind the entire universe. Fitting anything more than an equally small amount of matter into such a space would break the law of conservation of mass.
I didn't see this before, and I wish I hadn't. This statement requires more *facepalms* to be performed than can be performed in a lifetime.
Omegastick, you truly have no idea what you are talking about. Please stop telling people about physics if you don't understand it. You are only spreading misinformation, and it's only a matter of time before someone takes you at your word. That is a terrible thing to do to a person. It's not as bad as the news media telling people that sheltering from tornadoes under overpasses is a good idea (it isn't), but that kind of thing starts with people doing what you're doing. People didn't understand the physics of the Large Hadron Collider, but that didn't stop them from spreading the myth that it would create black holes that will destroy the earth. At least one person committed suicide because they didn't want to die by black hole. Well, the LHC is running, and we're still here, which means that the people who started that myth killed more people than the LHC. I don't expect anyone to die as a result of what you're saying here, but please, knock it off. There's enough ignorance in the world, we don't need you making more of it.
And there's no way that you could even fit one person into an infinitely small point, never mind the entire universe.
Why, at the beginning of the universe, would there be people to fit into an infinitely small point? We are talking about a time before even subatomic particles existed. The only thing I've ever heard that is supposed to exist at the big bang is energy, and as far as I know, there is no minimum size for that. Secondly, conservation of mass is a misnomer, and I'm fairly sure it's not even a law, but a simplification taught to entry-level students. Mass and energy are interchangeable. There was no mass and no particles at the big bang. There couldn't have been, partly for the reasons you said above. Physicists
know this. They don't need you to tell them that. It's their job to understand not just the obvious, but to figure out that which isn't obvious. They are currently working on finding out exactly how mass first appeared. That's part of what the LHC is for, to see which, if any, of their hypotheses on the subject is right.
