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

Never really thought about this, but shite, now Im bothered. So if the universe contains everything known then it's expanding into something that doest yet exist...???

thinking about the size of the universe is one of those things that makes my brain do flips and eventually sputter into a cloud of smoke...don't think I'll ever be able to wrap my head around it

If you intended to say that, I wouldn't have gone with the comma.

They say heaven is 10 zillion light years away.

Yes it is. It’s a tiny amount that has no practical effect Until you start talking a distance of light years but it’s still there.

Same thing for time dilation: time moves slightly slower (in a measurable amount in fact) for people riding along in the interstate than someone stationary. It’s just not significant until you go really fast.
EDIT:
I see the confusion now: shitty phrasing on my part.
The space between the earth and the sun IS increasing. Or more accurately: Space. The DISTANCE remains the same because the earth simply moves inward because the rate of expansion over the distance is so low it can’t overcome gravitational forces.
That doesn’t change the fact that universal expansion is occurring on even the solar system scale.

I knew you were going to ask that, c'mon man, that's a bunch of malarkey and you're a lying dog faced pony soldier and my baby boy Hunter be a good keed!

How does anyone know what is "stopped" in space when everything is moving?

Because the big bang theory is masturbatory bullshite, something we'll laugh about 100 years from now while believing something that will be laughed about 100 years from then.
It's what we do.
It's what we do.

What?
that makes no sense. there's still 3 dimensions from the perspective of the surface. The surface isn't moving across just 2 planes.
The surface is a 2 dimensional universe warped into three dimensional space.

It is correct. Volvagia is one of the few actual scientists on this board, and yeah, it is true.
No it is incorrect... if the Earth were moving away from the Sun humans would not exist

Tell us how it all started then.

Everything is checking out so far for the big bang type start. I don't think that will really change. What's more likely is that we may find out the big bang is just one of many in a cycle, or one of many with parallel universes

That's why the term observable universe exists.
Correct. The observable Universe in our time is 93 billion light years wide. It will become perceptibly shorter as time goes by.
The size of the entire Universe will grow larger with time, however. It is currently 10^20 times the size of the observable Universe. That’s 1,000,000,000,000,000,000,000 x 93,000,000,000 light years wide.

The Universe is expanding faster than the speed of light.
(Galaxies aren't expanding at the speed of light, for instance. The fabric of space itself is and that CAN travel faster than the speed of light. If you want to get deeper than that it gets extremely technical)
Thread? I think so.

The power of “local” gravity is still strong enough to counter the effect of the dark force, which will eventually reduce everything in the Universe to its base and time will stop. Even the strongest natural force we know of, the strong nuclear force that holds quarks together, will yield to the dark force.

Trying to understand what you’re saying. So that wouldn’t be a heat death of the universe but rather something related to dark energy?

How do you know this?

Define time as movement and movement as change. No movement = no time = no change. Given what we know right now, dark energy will cause entropy to increase to the point that everything will come to a total stop. There will be no movement, no change, no time.
