What is the Big Bang Theory and What Does it Tell Us?

Question

What do we mean by the Big Bang Theory? Is this the origin of the universe? Demonstrate its usefulness.

Answer 1

Big Bang Theory suggests that the Universe may have singlesource in the form a singularity which expanded subsequently. Rather than an explosion in space, it was the expansion of space. The Big Bang marks the birth of the Universe at this point, which was extremely small, hot, and infinitely dense. As space expanded and cooled, the first stars and galaxies were formed. The cosmic microwave background radiation constitutes a phase of the young universe and is widely regarded as one of the pillars of evidence for the Big Bang being the creation event of our universe. The theory covers the genesis of the visible Universe, however, it creates many astonishingly difficult problems for the human mind: what was before the Big Bang and is it the only universe constructed or one of many.

If the big bang was 13.8 billion years ago how come the observable universe is a radius of 46.508 billion light years which then infers faster than light travel which is impossible........?

The big bang theory sound beautiful. But, some how it does not convence me. The human brain still in the primitive stage to understand it.

Nothing makes sense without a creator or creators. God or advanced aliens is the only logical explanation

I believe, or rather, I imagine that the big bang theory is almost correct, only that it doesn't start from a singular point. It's more like a big loop, where this matter (space and all it's components, including black holes) is spit out from a hoop\hole and travels far and expands and then makes a large u turn around the hoop, once it meets the limit, after which there is nothing, impenetrable nothing and then goes back, compressed into  the hoop\hole on the other (in\back) side to be spat out again in a never ending cycle.

I understand they think the universe came from a singularity. Why did they think it came from a singularity? How could you predict that?
