“A 'hypernova' is a supernova (exploding star), but, like, more so. (It’s defined as being any supernova that’s at least 10 times as luminous as usual.)”

“A 'cataclysmic variable' is where a compact dense white dwarf star is in a binary orbit with a bigger puffier star & the WD (white dwarf) rips material off its companion & that material detonates on the WD’s surface.”

“I mean OK the fact that we can WATCH THE SUN VIBRATE & figure out what’s inside, that’s cool, but we can also do this for OTHER STARS. It’s called asteroseismology & it’s kind of blowing my mind today.”

“'Violent relaxation' comes from highly technical uses of both those terms. “Relaxation” referring to a system (eg, stars in a cluster) achieving some equilibrium (steady) state, and “violent” meaning rapid. It can happen when mass comes together quickly gravitationally.”

“'Spaghettification'” is what happens to you when you fall into a black hole feet first (for instance) and the gravity is so much stronger on your feet than your head that you’re stretched out to some kind of spaghetti-like carnage-shape.”

“Stating scientific facts about the atmosphere of our planet is not and must not be 'politics.' Reality should not be a political stance.

If someone's political stance requires preventing scientists from informing you about your own planet, that's not politics, it's oppression.”

“There are something like a trillion galaxies in the observable universe, of a range of sizes. And galaxy collisions happen a lot.

In fact, galaxies primarily grow by cannibalizing other (smaller) galaxies. Our own has eaten several—we can see streams of stars as debris.

In fact, galaxies primarily grow by cannibalizing other (smaller) galaxies. Our own has eaten several—we can see streams of stars as debris.

In addition to making the galaxies look like a train wreck (this is the term we often use), the merging can also cause new stars to form.

Throwing a lot of gas together & stirring it around can create new stars. And it can feed the big black holes too.

For all that chaos, collisions between stars themselves are actually pretty unlikely. There's a LOT of space between stars, even in galaxies.”

“Global warming doesn’t mean every day is hot as the surface of the Sun from now on. Winter still happens & occasionally some of us will be very cold.

If you want consistently hot global temps. though it is only a matter of (a very long) time until the Sun swells to its red giant phase

On the scale of the cosmos, though, the universe is cooling, & is probably doomed to a cold empty death & cessation of all processes

In some sense, every expenditure of energy, every word spoken, adds to the disorder of the universe & brings it closer to this 'heat death.'”
