Musing about the universe

If the speed of light is constant, and the "Big Bang"(according to Google) happened 13.8 billion years ago, then how is the size of the known universe (according to Google) 93 billion light years across? Shouldn't it at most be about 28 billion light years across?

Well, they invented “inflation” and other handwaving, including “dark matter” because their math doesn’t actually describe the observed universe given their assumptions.

I think the problem is that though they THINK they understand the laws of physics, they really don’t. There are glaring issues, which caused people to wander off into insanities like ‘string theory’, and other nonsense.

Scientists keep trying to put a measurement on the size of the universe. The heavens show forth the glory of God. To limit the size of the universe is to limit the glory of God. Won’t happen.

“Supposedly, due to this theory extension, space itself continues to expand and enlarge — ALL SPACE, EVRYWHERE.”

Thanks. That explains why everyone is getting fatter, and no diet works. It’s the fault of the space expansion. I’m off to the bakery to buy a chocolate creme cake.

The real truth is we will never know for sure.
What all this talk DOES is keep Academics employed who are not capable of holding a job in the real world.

The JWT has for sure introduced some new ideas into the question. I don’t believe we can have any idea how large the universe is, we can only deduce how far we can see objects in it away from us and that currently happens to be about 13.8.billion light years. Before James Webb it was about 13.5. The universe didn’t grow because of the Webb telescope but we can see a little farther out into it.

The JWT can also see a longer wave of light than other telescopes so that light that would have dropped off our ability to see is now visible to JST. To double the distance that we can see, that is add one directions visibility to the opposite directions visibility would give us 27 billion plus light years. We know from what we can see however at 13.8 billion light years that it is larger since we can see formed galaxy’s and stars at that distance. If the big bang theory is correct we should see large gas clouds and no individual stars before we get to the edge of what we are calling the universe.

> time ... linear

Language fails. Linear against what? Maybe you mean irreversible?

But then I say reversed from what perspective?

For sure our mortal context is INSIDE of time. I think of it like we are moving into the future but turned around facing the past. We can see the past but not go there. We are going into the future but can’t see it.

Getting outside (context-wise, or “dimensionally”) of time, one could move around in whatever space that is, and go back.

The little book Flatland can help here. If time is a dimension, and there’s a dimension higher than that, then maybe some entity is there, and outside of time.

Creationist Christians (those who see God as omnipotent) simply think of it as time having been created by God like everything else.

But you can imagine a higher dimension without that belief, though I find unbelievers very close-minded in general on the idea of any being at a level completely above us, that can see us in ways we cannot, and can make impossible things happen. Like a 3D being in Flatland freaking out the 2D beings. Or not too much different from a human observing a bunch of ants.
