Probably proper knife skills. I’ve always been pretty good with a knife, but I’ve been taking my time to really refine the skill as I do a lot of cooking for large groups so speed is extremely useful. I honestly learnt a lot of it indirectly by just watching how chefs use them, but for the theory and all that I started with Lan Lam’s video on knife skills over at the America’s Test Kitchen yt channel.

I’m about to be going to an event where I’ll be cooking nearly a thousand meals a day for three days, so I’m going to be putting it to the test. The one nice thing is we’ll have a team of volunteers to help with ingredient prep, so it should be okay but daunting none the less.

That’s a pretty reasonable misunderstanding, I don’t speak for anyone but myself but generally as long as there’s no malice involved I’m not upset by an accidental misgendering.

I’m on jerboa too and didn’t even know there were specific pronouns on accounts, I just chucked mine in my bio.

Judging from the other comments it’s not for everyone, but personally I love my Wednesdays off. For me it’s mostly about dealing with accumulated fatigue due to a health condition though, and I definitely agree about the errands. When I have lots of medical appointments they’re so easy to schedule lol

If you’re looking for books, then it depends on what field you want to study. Generally just I’d search for recommended textbooks for that field and then I’d definitely buy it and wouldn’t just download it from libgen.is

There’s basically no way to answer these questions using real physics I’m afraid.

It definitely can’t close it’s mouth faster than the speed of light. Yes it would have a strong gravitational pull, almost definitely so strong that it would just collapse into a black hole and not be able to exist. If it weren’t that dense, then it would basically just be a big diffuse gas cloud that couldn’t do much anyway, it would basically have to be a proto galaxy to not collapse into one.

If it’s using magic to exist, then anything is on the table.

That’s not entirely accurate, the force it applies to close it’s mouth would probably travel at or close to the speed of sound along its jaw, but it could reach the speed of light by applying that force if you ignore a number of problems. One of which is that it will turn into a black hole at that scale, it’s much too dense.

On your second point, it’s hard to make any of those into galaxy killers. Supermassive black holes exist at the centre of virtually every galaxy and don’t do a ton, and even quasars only have limited killing range as there are limits to how collimated a beam of radiation can be. White holes are more complicated and I don’t have enough space in a single comment to go into the nuances, but they’re about as harmless as black holes really.

The only thing I can think of that would destroy all life in a galaxy would also destroy the universe, and that’s to trigger a false vacuum decay, but that might not be possible anyway.
