Evidence of big bang theory?
So from my understanding and maybe I'm wrong correct me if I am please cause I'm not 100% sure, but evidence for the big band theory is.....
1. The universe is now expanded so it must have at one point been compressed
2.Cmb exists because there was at one time a hot spot which is believed to be right before the bang happened

The big bang theory is corroborated by the laws of thermodynamics.
1.) Conservation, the first law. The universe is analagous to energy, which constantly changes form. Stars are fusion reactors that convert hydrogen in to more complex elements and then the thermal conversion to plasma reduces them back to hydrogen in a continual cycle.
2.) Entropy, the second law. Energy expands in a useful manner until it the excess is dissapated as heat and thermal energy referred to as expansion, then when it reaches a certain point.
3.) Entropy limits, the Third law, energy cannot reach an absolute limit and when it reaches it's peak it contracts back into a singularity until it it reaches atomic collapse, which results in critical mass of fission and expands again and repeats this cycle ad infinitum, hence the cycle of big bang.

Actually, there are several sub-section.
1 a) the universe is expanding as you mentioned AND
1 b) the universe expansion rate is a function of distance, bringing additional evidence to the fact that all matter was essentially occupying a very tiny spot about 13 billion years ago
2- the cosmic background radiation level is consistent with the universe being 13 billion years old
3- the metallicity of the oldest stars is consistent with that age also
And I am sure there are several other details also. But the main point is that all of those agree with one another.

I am sorry but I have a hard time figuring out how on earth people can be this stupid and still know how to type.
If you want the evidence used to support a scientific theory why not ask your question in a science section? Can you be so stupid as to think you would get a more legitimate answer in the religion section? Would you ask legal question in the sports section or a question about pet care in the politics section? Then why ask a science question in the religion section?
Do you really want a legitimate response or are you only interested in nonsense responses from religions nut-jobs that refuse to accept science over your superstitions.

1. The universe is EXPANDING, it is yet to finish. And if you took a physics class in school you'd know that any object that has momentum can be traced back to its origin. I'd give the full lecture but that takes a few hours to get through.
2. if expansion is possible, so does compression need to be. Without the potential to expand it cannot compress.

I notion the giant bang was a verified event. How can it be changed? Anyway, the Bible says within the commencing God created the heavens and the earth. The Bible does no longer say how or when this happened. Individuals assume that it used to be in one day. The ingenious days weren't 24 hours lengthy. They have been time periods.

1. Some scientists aren't even sure if the universe is expanding.
2. They say the cmb is the fingerprint for the big bang but how would they know that if they never seen a big bang before?
Just conclusions I came to but yes, you are right.

the universe is ever expanding. scientist can trace that expansion to a certain starting point.

That's the second grade version. Are you interested in the version for the scientifically literate, or would that be too hard for you to understand?
