The big bang didn't happen at a point in space. It happened everywhere simultaneously. Based on its geometry the universe appears to be infinite, but of course nobody can really know for certain. That's just the overwhelmingly most likely scenario.

What does that mean exactly? What aspect of the geometry is infinite?

A space can be either positively curved, negatively curved or flat. These are concepts from differential geometry but they're fairly self-explanatory. A finite universe would have to be positively curved, like the surface of a ball. Studies of space have all but ruled out the possibility that the universe's geometry is positively curved, meaning it's overwhelmingly likely to be infinite. This is all just inference, of course, and we will never know the true shape of the universe for certain.

If you want a proper explanation you need to visit the dudes on Callisto. I went there myself but I'm not a phycisist so I didn't really understand. I only went there for the martial arts tournament anyway, it's the best one outside of Quaoar but those guys can punch apart meteors and I'm nowhere near that level. Yet.

That isn't what big bang cosmology says at all, though, it just says you can only observe based on the movement of light.
How could space be infinite if it was entirely generated within some amount of time that was not infinite?

The universe was always infinite, even at the beginning of the big bang.

That is steady state cosmology, not big bang theory.

No, steady state says the universe has on a large scale always had the same density. The evidence we see in the sky doesn't support that idea. It's evident that the universe was dense and hot a long time ago and that as the metric expanded its matter and radiation density dropped.

humans can only understand the universe through sexual analogy, hence this concept of a "big bang"

You are mistaken. Flat space can be finite. A flat torus is a simple example. There are even ways to make negatively curved spaces finite.

This, the cosmology "experts" who claim that they know everything about the entire universe all have the same exact collection of personality traits just like any group of people suffering from the same physical illness would have all a similar collection of symptoms. Belief in the big bang is just a tipoff of a severe personality disorder, the fact that they are mentally ill is the only reason they can believe in their ridiculous twisted logic
