Big BANG Problems?

Question

For the past months now, I have been getting myself into alot of space topics. I really am starting to find this entire topic very intresting. I started from scratch, with our planets, solar system, galaxies, and I kept moving on..

Where am I now? Well, I just finshed reading about the cosmic microwave background radiation, which seems to be really amazing, considering its existent everywhere in our universe. I have also learnt about how the universe expanding, with the evidence that stars around us appear red shifted.

I never thought I would dig deeper than this, but I am, and now I want to enter this field.

Anyway, yea so I am investigating problems with the Big Bang, and there seems to be three really big ones, that I dont seem to understand.

1.) Horizon Problem
2.) Flatness Problem
3.) Density Flucation Problem

Anyone here have any knowledge on these topics?

Thanks for reading.

Answer 1

All three problems have been solved by what is called the inflationary theory of the Big Bang.
Since information can travel no faster than the speed of light, there is a limit to the region of space that is in causal contact with any particular point in the universe. The horizon problem is that the Universe seems bigger than its age warrants.
The flatness and density problem is that the universe is too homogenous and have similar densities everywhere, even regions that can not have been in physical contact.

See this wikipedia page

and its hyperlinks too find a more complete explanation.

Answer 2

From where you are in your studies I have a book to recommend. For me it was a work that took me up a level in my understanding of cosmology. The book is called The Structure of the Universe, by Jayant Narliker. The way it's put together you will find it accessible no matter what level you have reached in your mathematics, which is a stumbling block with many cosmology texts. Narliker separates the math from the ideas in a really interesting way.

Narliker is also the author of the single most interesting book on the subject of time.... Time's Arrow. I'm pretty sure both of these boooks are still in print.

Answer 3

Georges Lemaître (1894-1966), the Belgian astronomer.
Check him out on the Internet .

Answer 4

First it is necessary to determine if a Big Bang ever took place? If something is not feasable than you will find that questions about it cannot be answered.
The Big Bang is a Creation theory wether it really happened that way is not possible for man to prove.

Answer 5

I think we could benefit from a statement of what the problems actually are. That will inform us where you are at.
