A singularity is the single point mass at the center of an ideal (Schwarzschild) black hole. But mathematically, that can only happen if the mass that forms the black hole isn’t rotating. In reality, all the mass in the universe is moving around, because mass is not distributed uniformly, so gravity is pulling stuff around in a big mess. So when a black hole forms, it’s definitely a rotating (Kerr) black hole.

A rotating mass has different gravity than a non-rotating mass. Not by much, but when you’ve got the enormous mass of a black hole, it becomes significant. This causes objects “falling into” a black hole to “miss” the point at the center, and form more of a cloud during spaghettification.

The article is fairly accessible if you sit down and read it.

Honestly, inside the event horizon, everything stops making sense compared to our day-to-day experiences. The immense gravitational forces distort space and time. It doesn’t really make sense to think about objects remaining intact as recognizable objects once they cross the event horizon.

Delete the directory, create the file. Docker creates a bind mount as a directory if it doesn’t exist.

I don’t think there’s any such feature.

If you don’t agree with the actions of a mod or admin, choose a different community or instance.

Let’s say every lemmy instance has a “memes” community, and you want to find them. Unlike DNS, where there’s one authoritative record for memes, to find all the different communities for memes, the local instance would have to send a search request to each other federated instance, wait for the results (what if the remote instance is offline?), figure out how to sort them, paginate them, and display them to the user.

Would it be possible? Yes, but it’s probably more of a headache than the devs want to implement. If you check the issue tracker, you might find some discussion about it.

Use your client’s search function? On the standard web app, click the magnifying glass icon in the top right, pick the community, some keywords, and search.

No, that is not currently possible, but there is an issue open for it: https://github.com/LemmyNet/lemmy/issues/3057

You’re welcome to contribute to the project.

If you really want to be sure, create your own instance. Reddit could also up and disappear tomorrow. Less likely, since they’re trying to make it profitable, but Advance Publications could certainly say “no, we’re done, shut it down” and it would be gone.

I would suggest using the RSS feed an a reader that sends notifications.
