Well, as my emotion states, I am quizzical. I have been reading this book for a little while now, called "The Big Bang" and it's by Simon Singh. If anyone has a chance to read it, I really recommend it. But anyway, I'm only half-way through it, and I'm learning lots but I have a few questions about this big bang theory. Okay, so it seems as though most galaxies are moving away (but yes, our galaxie is moving as well), and this fits with the big bang theory, but then why are there a few galaxies that seem to be moving toward us? In the book, Simon Singh uses the analogy of a balloon. If you draw dots on the balloon, each representing a galaxie, and then blow into the balloon making it expand (kind of like the universe does in the big bang theory) the dots become further away from each other. But then, why do some move closer? I'm not sure if this is going to be addressed in the book or not...
"you're my, brown eyed girl!"... sorry, had to sing to the song on the radio for a minute. Anyhoo, back to the theory. I've heard some people say that the universe was incredibly small. I'm sort of wondering how small this "incredibly small" is. I mean, when creation happened, was the earth as big as we see it today? or did it grow over time? If it grew over time, is it still growing? And why is the universe expanding when galaxies are not? And how is the universe expanding anyway, because I don't understand how something can expand into nothing. I mean, isn't the universe all there is? Is it not everything? So, is the universe expanding, or are the galaxies actually just moving.
Okay, to start off, I don't study this stuff, I'm just interested in it and trying to find answers. So, with that being stated, and now that you know that I do not know a lot of the theories and knowledge of theuniverse, I would like to state my theory. Think of the earth. Once upon a time, years and years ago, all of the lands were connected into one land called Pangea (or something similar... working off of memory here). Then, the lands all split up and are moving away from each other at a constant speed. Now, the speed is considerably slow. However, what if that's what the universe is doing? Maybe everything in the universe was all in one area at one point (well, not all as stars blow up and all those types of changes occur as well, just like some things on earth change such as mountains forming and earthquakes and volcanos), then they started spreading outward. Maybe the universe is a globe like the earth and they'll eventually meet at the other side, then bounce back... keep in mind, I don't have proof, so I'm stating this as fact. Just an idea. I still have the problem of the non-constant velocities of the galaxies as they spread outward. I haven't worked that into my idea yet. But, it's something to think about.
In the meantime, I have some pictures to look at in my e-mail and I'm incredibly tired. I'll update further with more information as I think of it.
the redshifts work well with it, sure (except I'm not clear on why galaxies themselves don't expand) but what about the blueshifts? There are couple of galaxies that (so far anyway) were found to be blueshifting
