If you are here asking: "Is this a science meme?"

Probably, yes. We use the Dawkins definition of meme: a replicating idea, not just an image macro with a fact on it. A good post here doesn't need to teach you something. It needs to make you ask something: who, what, where, when, and especially why or how.

Science isn't a filing cabinet of facts, it's a conversation. For example, a photo of an eel or other localized wildlife counts because most people never see one, and wonder is the first step of inquiry. A car meme counts if it makes you curious about what's under the bonnet. If you want to talk about something you noticed in the world, chances are someone else wants to talk about it too.

We moderate for vibe, not category. Pruning is light, especially where a post creates interesting discussion. Experimenting is encouraged.

See the pinned paper on Shitposting as Public Pedagogy if you want the academic case for why this works.

but like, the whole point of black holes is that time and space switch places, which means all the matter/energy inside them is packed in a single infinitely dense point

that's a pretty big thing to ignore

It's more complicated in ways that aren't intuitive.

Yes, at first glance, it appears that everything would continue to collapse down to a singularity. But a singularity is literally a failure of our model of physics. It's like dividing by zero- the result is nonsense. It's not an actual object.

From our perspective, time is stopped at the event horizon of a black hole. The singularity never forms because there isn't time for that to happen. If you fell into a black hole, would a singularity form as you are crossing the event-horizon? Maybe. Maybe Hawking Radiation is a thing and you're cooked by a wall of radiation as the collapsing object literally evaporates beneath you.

Keep in mind that high densities are needed for stellar black holes to form. An event horizon would form around the solar system if it was filled with air- and yes, there are black holes of this size.

It's less than time and space switch in a singularity, and more that they are "undefined".

Like dividing by zero.
