Thermodynamics question

[Dale (evolutionary providentialist)]

But the expansion is faster than light so that more and more of the universe passes outside the visible limits, rather than being able see more of the universe as time goes on (which is what you would expect if it wasn’t expanding so fast).

After the initial cosmic inflation, it wasn’t always expanding faster than the speed of light. If it had been, we wouldn’t be able to see anything except our own galaxy, and maybe not even all of it.

So I was wondering when did cosmic expansion exceed the speed of light, and found this:

One of the most surprising facts about the Universe is that if you do the conversions and take the inverse of the expansion rate, you can calculate the “time” that you get out.

The answer? Approximately 13.8 billion years: the age of the Universe. There isn’t a fundamental reason for that fact; it’s just a fascinating cosmic coincidence.

Ask Ethan: How Does The Fabric Of Spacetime Expand Faster Than The Speed Of Light?

That may not be the answer to my question, but it looks like it might. Anyway, if it had been much sooner, we would be able to see way less.

It also fits nicely with these:

@Dale

…a secular astronomer said near the period of the total solar eclipse in the U.S. in 2017 that the size of our moon was magical.

@Dale

… It is cool that it sure appears that the universe was designed to be discovered – from here, with our special moon. …That is not to mention all of the other details about why so much of the cosmos is visible, unobstructed, from here.

…and during the brief tenure of humankind.

Have I ever mentioned that I like coincidences?
