I don't think it means anything, it's probably just a curiosity. Simple equations like that probably don't work correctly when applied universe-scale.

The event horizon radius grows linearly, so it's possible for a black hole to have a lower density than water (around 7 billion solar masses). Another curiosity is that if you plug in the mass of the regular matter in the observable universe into the schwarzchild radius equation (R = 2GM/(c^2)) you get a black hole event horizon larger than the the observable universe.

If it's an existing commit and you're already converting the repo, you can just convert the commit messages as well.

Since SHA-1 is already broken (just expensive in terms of GPU-time), then the text "please see commit " is also already broken.

C# is a "first class" language in Godot and doesn't need a GDExtension, but it's not compatible with web builds yet. There is a draft PR that includes C# support but it adds about +50 MB to a web export and is also missing a few features.

Yes the event horizon would be smaller than the width of a proton. Good luck getting anything into that with 300 TW of gamma rays coming out of it.

If you had a small black hole in a lab you could generate power from the hawking radiation, likely enough to power the entire world. A 1,000,000 ton black hole would last over a thousand years without feeding it more mass and produce about 300 TW of energy (increasing over time, so you better keep feeding it). You'd also need some pretty good sunglasses to be able to watch things being thrown into it. Also I'm not sure how you could throw anything into it given the amount of radiation pressure... Maybe a dedicated particle accelerator could do it.

Anything smaller while also lasting long enough to do an experiment on and you'd likely end up producing too much energy and destroying the planet.

The M87 supermassive blackhole is thousands of times as massive as Sagittarius A*, but since Sagittarius A* is a lot closer their emission rings appear roughly the same size in the sky (42 μas vs 51 μas). Both have already been imaged by the Event Horizon Telescope. https://en.wikipedia.org/wiki/Event_Horizon_Telescope

Yes usually, since an important aspect of steganography is error correction. For example we know that SynthID is robust enough to survive resizing and small blurs.

Even if you remove a watermark, the companies still have a record of which images they have generated and for whom. Even if you remove the obvious watermarks, all major image generators are using steganography to embed hidden information that you can't be sure were removed. This is a type of one-sided arms race where one player gets to be invisible if they want to.

It has been my experience that this is currently the case. I haven't had to even open protondb or search for a workaround in over a year. The only titles I know that don't work are a handful of multiplayer games that have intentionally disabled linux support.
