Birth of the Universe

[tutrakan4e]

I've been thinking about this lately: Since sub-atomic particles can appear out of nowhere and teleport but we can't how do we know that the Universe can't? If sub-atomic particles have different physics than "big" stuff, then the Universe should have different physics than the things that make it up, as we have different physics than the things that make us up. So actually, our universe can be actually a sub-atomic particle in a bigger universe. Did I just prove the theory of universes in other universes? Help me, scientists, I'm confused

The very big stuff and very small stuff have the same physics, we just haven't figured out how to put them together consistently yet. We'll get there.

it's not really that we don't know how to fit them together, we do really, it's just that as you increase the size of a system everything necessarily turns into advanced statistical mathematics that emulate classical mechanics. Most people assume that the problem is that stuff on vary large scales doesn't add up when considered from the very small scale, but the issue we're really having is that we aren't seeing what causes the very large stuff when looking on a very small scale and that messes with our statistical calculations and causes chaotic predictions when we don't know all of the details.

On the plus side, the Genesis project managed to capture a piece of the Sun. It's been analyzed at UCLA and is putting limits on the hypothesis of the formation of the solar system. It may not be all THAT long before we have a (more or less) accurate picture of how the solar system formed. In the meantime, we should expect a lot of long standing beliefs to be challenged and disproved. Like the fact that the Earth's (and other inner system) oxygen isotopes are anomalous to the rest of the system, when it was previously considered to be the other way around. Knowing where to begin looking helps understand what else you can look at.

No, they don't. They really don't. Some things are very different.

I phrased that poorly, they have the same physics that we haven't discovered yet. The idea that one theory will eventually unify the apparently contradictory theories we use now. At least that's my layman's understanding.

Well, maybe. We hope there is a grand unified theory, but there might not be. We'll see.

I am convinced the larger scale processes are emergent from the smaller scale ones. They might not interact or follow each other in a way that makes sense to us now, but it does mean that there is a unified theory, as they are not truly seperate things.
