For files I just use WebDAV that’s built in to Apache. It’s really not fancy, but does all I need.

I use RoundCube, I think it’s one of the oldest solutions out there, and is pretty good (and not ugly as of a few years ago).

So the document had been classified as written in Nabataean, but it’s unclear if that turned out not to be the case in the end?

Just saw the scatter plot and line and my mind immediately screamed “bullshit” without knowing what this was about at all. Only then I read the text.

Not sure this statement is true if “more closely related” is understood as shorter combined time between the two species from their most recent common ancestor. Hummingbirds and brachiosaurs had a more recent common ancestor than brachiosaurs and triceratopses (albeit probably still quite close to the dawn of dinosaurs in the Late Triassic ), but the latter pair lived closer in time to the common ancestor of all dinosaurs (while hummingbirds are from the Oligocene).

Yep, you got it right. The accretion disk is actually really flat. Those images are produced in simulations that take into account the curved (and very complex) paths light takes in the vicinity of a black hole. These images really depend on the angle between the line of sight and the disk.

Astrophysicist here. Yes, space is crazy, but interesting things to keep in mind:

1. The size of a star is determined by something called the photosphere. With those extremely massive stars, you can be hundreds of millions of kilometres “inside” and not yet know it.
2. Similar story with supermassive black holes, from the perspective of an astronaut falling in, they wouldn’t really be able to tell when they cross the horizon because the tidal forces there are very small (they will inevitably fall towards the centre and get spaghettified at some point)
