So just pondering..
Here is a part that will REALLY screw your mind up. There are plenty of things that are moving away from us FASTER than the speed of light. But they are not violating any rules of relativity either. Relative to the space they are in they are not moving faster than the speed of light so physics still remains intact. The whole thing is about the universe expanding, and the further away from us you go, the faster it expands. But expansion is not all the "stuff" getting further apart. Expansion is literally the SPACE expanding. So at some point , since expansion seems to be happening faster the further away you get, then something far enough away that is moving at some "normal" speed relative to things around it can actually be moving away faster than the speed of light relative to us.
So, with that in mind, there are literally parts of the universe we can never see no matter how large a telescope we can build, because the light from them will literally never reach us to start with. So ... we can never see nor reach the edge of the universe in this scenario. And the more you think about it, the more it hurts lol

the edge of the universe. Arthur C Clarke had a collection of short stories, I think it was Nine Billon Names of God.
In one of the stories the astronauts had traveled to the known edge of the universe, which ws a wall,
One of the made the decision to find out what was beyond the wall. So he climbed up on top and started walking off into the fog in a straight line.
Eventually he came back out and the other astronauts asked him what he had found a the edge that he came back.
The first astronaut said no he had just kept walking and wound up back where he started.
Clarke's version had a lot more words. but you get the point.
Understanding the size of the universe as F'ing huge is good. It keeps my engineer ego in check.
for I am just a pawn in the chess game of life.

I'm still pondering....
I saw a headline about finding the hottest stars in the galaxy and the universe.
I "get" that if we use Celsius aka kelvin - a whole bunch kelvin starts at zero indicating no matter motion.
I have a much harder time conceptualizing 100 million degrees or other numbers talking about the "temperatures" inside a sun.
Matter as we know it, simply doesn't exist.
It's a plasma of subatomic particles under incredible pressures and in various states of fusion yielding ungodly amounts of energy.
How does one begin to describe a temperature here? Pv=NrT just seems to come up a little short.

After trying to read the Steven Hawkin's book
https://www.goodreads.com/book/show/...istory_of_Time
After I re-read the third chapter twice and could not wrap my head around it I came to the conclusions that greater minds than mine would have to answer these questions.
I.E. The minds that figure out when to launch a rocket so that it can rendezvous with the ISS is definitely above my "pay grade".
Or the minds that calculate that the core of the sun is about 27 Million Degrees Fahrenheit?

I read A Brief History of Time a few years ago upon a friend's recommendation. I got some of it but a lot of it just made my brain hurt. It may have been written for the layman but I think a deep understanding of physics and cosmology would be really helpful, but personally I don't have time to pursue an advanced degree in any relevant branch of physics.
Time flies like an arrow.

I am guessing Vito has read it but will check. He might get it since his master's is in physics and he loves reading physics books for fun. Just looked on the shelf and I see two other books by Hawking. Not my bag, but opposites do attract in this case.
