re: If the universe is 93 billion light years across, how is it only 14.5 billion years old?

First, you start with a roux

You're comparing a measure of distance with a measure of time.

So did matter travel WAY faster than the speed of light right after the Big Bang? And if it did, as would be necessary - would that matter have traveled back in time?

The space between the earth and the sun is increasing.

This is not correct. At all.

It is correct. Volvagia is one of the few actual scientists on this board, and yeah, it is true.

Spacetime can warp. The speed of light is the speed limit of anything locally, and it says nothing about the medium that the light is traveling through. Also, space wasn't always accelerating. There was an acceleration period right after the Big Bang, followed by a few billion years of deceleration, followed by the acceleration period we are in right now. I think this all boils down to dark matter/energy that we haven't figured out yet and how it has affected the space between galaxies but is not able to directly affect galaxies themselves. So galaxies and star systems are won over by gravity and don't lose their form.

Oddly enough, space has expanded to roughly pi*radius, but not quite. This could be a coincidence, but I doubt it.

I do think there is a relationship between what we see in our universe and how we came to be and what we theorize happens inside of a black hole. Just recently, the science community said it was pretty certain that information is not lost when it enters a black hole, it is actually just encrypted/scrambled on the surface(Hawking radiation), and Roger Penrose recently brought up the idea that perhaps we could learn about what happened before the Big Bang by observing the effects found around the edge of the universe(CMB), which to me seems strangely similar to what is happening on the other side of a black hole from our perspective. Intuitively, I like the idea of a multiverse, with our universe existing inside a bubble. With that, you can have the bulk existing outside our universe, which connects all universes, which could then either follow Everett's interpretation of QM, the many worlds, or simply just be a finite amount of universes.

I’ll worry about this when they can tell me what’s in the depths of the ocean on our planet. It amazes me we still haven’t really sunk money into fully exploring our own planet all the way by now.

We are never gonna make it into deep space in our lifetime. If something out there is advanced enough to make it here and advanced enough to get here quickly, surly the could eliminate us with a quickness.
