>Universe is 13.8 billion years old
>Observable universe is 93 billion light years in diameter

This doesn't make sense, the observable universe should have a maximum radius of 13.8 billion light years or a diameter of 27.6 billion light years after the big bang. Even if the universe expands faster than light, how could it possibly be "observable" if there's nothing but darkness beyond the 13.8 billion light year radius?

The oldest light we can see was emitted about 13.8 billion years ago at a time when their sources were about 13.8 billion light years away. Due to estimated rate of expansion, they are now about 46.5 billion light years away.

nah, more like 42 Million ly (0.042 bn ly)
space expansion is a thing

They keep you busy with that BS. The simple fact that you cannot observe a point where you started from is more than enough to see the amount of dumbness in science and the fanboyz. It's only one of many points why this hallucination is impossible. In addition it's proof "they" are right. When you cannot see stupid lies like that you are not egible for true science.

it's because of inflation. it's argued that in the early universe, the universe was expanding faster than the speed of light (determines finite size), whereas the observable universe is determined by light speed.
>FTL speed -> bigger universe
>Light speed -> smaller observable universe
this of course begs the question of the evidence in support of inflation. not my area of expertise - i honestly don't know

Do we know where Big bang happened? What's our direction?

galaxies aren't moving that much, it's space itself that is expanding.
the center itself bloated
so either there isn't a center, or everything is the center
