#2The description of the crests lagging the troughs made no sense to me. I have no idea what is meant. Anyone have insight?

#4Starts with Interstellar spoilers with no warning.

#5Nautilus continues to serve images with the wrong extension, for whatever reason.
The hero image is a HEIF with a PNG extension. Chrome doesn't care, but Safari does.

#6Seeing that picture of a star absorbing another, I got a dumb question:
Stars are balls of glowing plasma. If you were to vacuum it, as another star or black hole too close for comfort would, what would this plasma look like? I reckon it would not be visible, a bit like trying to vacuum fire. All you get is hot, invisible gas.
So effectively, the image at the top of the article is completely unrealistic. Any transfer of matter from a star would be basically invisible to the naked eye. You'd see two stars close by, and one getting imperceptibly smaller than the other that slowly grows.
Is that correct?

A crashing wave where the crest leads the trough would be like when you're surfing inside of a barrel wave. The crashing part is going over your head and landing in the trough.
In the case of this star simulation they are saying that the wave is crashing, but the crashing part is falling back on the back side of the wave instead of going forward over your head.

#8It's an Avi Loeb paper. He has a list of journalists he emails to promote his or his students papers. The papers are designed to elicit clicks -- correct, consequential or not.

I wouldn't recommend trying to vacuum fire... But if you were to do it, you would find you ended up with flames going all the way up your vacuum hose and into the dust collector.
So from that perspective, fire is very much vacuumable.

Fair enough, because it didn't have time to cool down yet.
But at astronomical scales, even if vacuum is a good insulator, the glowing plasma would somewhat cool down before it reaches the other star, I imagine.
