Is there proof of the big....?

Question

piece of evidence is the background radiation of heat left over from the Big Bang. This was predicted to exist by proponents of the Big Bang, and was discovered accidentally in 1963. It's the leftovers of the tremendous heat generated by the explosion, and is 2.93 degrees above absolute zero.
Where could i find this proof or theroy on the web^^^?
They say "Galaxy are expanding" when the fact is some have blue light and some have red, we dont no whether we are expaning or contracting????
Whats with that?

haha i forgot bang!

Answer 1

I don't know of any web sites that address the issue specifically -- try Google or Yahoo search. There may be a few nearby galaxies exhibiting blue shift, but as you go farther and farther away the shift gets redder and redder. To make this claim, a separate measure of distance is needed. This measure is found in certain variable stars (Cepheid variables), whose characteristic changes in brilliance are related to size and hence brightness. By observing a Cepheid variable in a particular galaxy, its distance can be determined.

Answer 2

Hold on, hold on. Before you go all gung-ho about this stuff, first get your numbers right.

Cosmic background radiation (as it's called) was predicted to exist in 1948 by George Gamow, and was discovered in *1965* by Arno Penzias and Robert Wilson, and it's temperature is *2.728* degrees above absolute zero. Since then, it has been mapped by the COBE satellite in the late 90's, and the WMAP satellite, launched in 2001.

You can bloody well find proof of this theory yourself, if you had access to some materials. This fall, I'm going to be building a microwave receiver and look into detecting this radiation for myself. It peaks at around 160.4 GHz, and is evident anywhere in the night sky you point a receiver.

If you'd like to learn more, simply Google "cosmic background radiation". I did a quick one, and I'll give you the most useful links in the sources below.

Hope this helps!

Answer 3

The only galaxies with blue shifts are those close enough that their peculiar motions are larger than the expansion rate. Since the expansion rate increases with increasing distance and the peculiar motions are generally small, this only happens to about 3-4 galaxies.

Answer 4

This web site has 4 items on the big bang

Answer 5

right now there is an ongoing argument between the 'big bang' theorists and the 'creationists'. there is no proof of anything, just more theory. you have to listen to it all and pick what sounds right to you. after all that's what all of them did! (i see no reason why the two are mutually exclusive.)
