Re: Astronomy and Space
i think musk and bezos desires are quite obvious if you look at it from the frustrated megalomaniac utopia point of view.
Imagine a world with no existing politics or culture, with a hand selected group of ubermensch who bow to you and your desires and you can do whatever you want with zero oversight or influence from earthly authorities.

Kepler's forgotten ideas about symmetry help explain spiral galaxies without the need for dark matter
The 17th-century astronomer Johannes Kepler was the first to muse about the structure of snowflakes. Why are they so symmetrical? How does one side know how long the opposite side has grown? Kepler thought it was all down to what we would now call a "morphogenic field" – that things want to have the form they have. Science has since discounted this idea. But the question of why snowflakes and similar structures are so symmetrical is nevertheless not entirely understood.
We have shown that information and "entropy"—a measure of the disorder of a system—are linked together ("info-entropy") in a way exactly analogous to electric and magnetic fields ("electromagnetism"). Electric currents produce magnetic fields, while changing magnetic fields produce electric currents. Information and entropy influence each other in the same way.

Re: Astronomy and Space
Stupid question maybe someone here has an answer for:
Let's say we came across a totally burnt-out star we had easy access to, what uses could we make of it?
---------------
I leafed through a popular science magazine a week or two back, and they had (probably) article 19 million about alien speculation. The twist this time is that perhaps we haven't come across them because they are hibernating. The amount of energy they need to run their advance civilizations requires a cooler universe, so they'll sleep it off 'til the universe gets to be the right temperature for them.
The first thought which popped in my mind was that a cooler universe is also a darker one...super advanced hibernatin' aliens probably would draw up plans for what do with dead star-stuff before their big nap. But I'm sorta drawing a blank on what that would look like beyond some very obvious ones. And search engines are no good for me on this brain fart.

Re: Astronomy and Space
Question:
The universe is expanding fast than the speed of light. They say the universe is 13 billion years old but at least 92 billion light years in diameter. Plus one other thing traveling faster than the speed of light involves going backwards in time. IE approach the speed of light and time slows down. Exceed it and you are traveling backwards in time. So if the universe expanding faster than the speed of light, is it expanding towards the big bang?

that made me think of beams of light going in opposite directions, which was a rabbit hole of physics babble

babble in the sense that massive scale and our comfortable scale on plane earth dont relate.
on a mathmatical level, I get that a super large number can be ignored when you are playing with scale on the tiny percantages of decimal fractions.
