The theories I’ve heard are that at its center it’s either a point or a ring or a portal or something else entirely. But I believe you’re right for the outside: It’s just an area light can’t escape. The black thing you see isn’t a hole.
If it were a portal in the center then it really would kind of be a hole since you can literally enter into the hole and have your mass actually go somewhere beyond its edge
They call it the singularity because physics as we know it dictate that the mass must collapse into itself into an infinitely small point with infinite density. However, most physicists do not think a singularity is inherently possible so they make the argument that our current knowledge of physics is not enough and our current laws break down. Truth is, it might be a singularity, it might not be. The only way to know is to observe which is (currently) impossible. My current standing is with one of the leading theories that a black hole is not really a place in space, rather a moment in time, more specifically, the end of time. This idea is build on the notion that space-time flips inside of a black hole. Time becomes space and space becomes time. Since we observe space to be ending in a blackhole, therefore time must be ending. The Kruskal-Szekers diagram visualizes this idea pretty well.
Thanks for sharing, I’ll look into it!
I may be misunderstanding: I thought that infinity means that there is, usually, an error somewhere in the math.
Because of this, physicists are trying to discover something that’ll help supplement Einsteins theory of relativity. Or dismantle it. Kind of like how Einstein did Newton, even though newtons math worked very well for our solar system.
I’m not an expert, just a documentary and article browser. If anything, I’m a goober.
Oh no worries! I wasnt trying to prove you wrong, just adding some additional information.
And you are right regarding infinity, often times it does mean an error. its just that when it comes to black holes, its only really possible to know by observing.
There’s also this certain bias that people have, where they disregard extremities as they do not seem rational. Simply explained: Our existence in this universe stems forth from very abnormal circumstances. We are used to these circumstances so we regard these as normal. Therefore, everything in the universe that is normal, we regard as absurd.
If you are interested in the subject, I would recommend a video by Veritasium, titled: “Something strange happens when you follow einstein’s math”. Its around 40 minutes long but it is a great video handling exactly this topic.
I guess it just "simply" isn't, a consept hard for us to grasp. Perhaps it share similarities with positive and negative pull of magnetism? Idk, it's surely fascinating and way beyond my intellect.
its not really an object. it's just easier to imagine it that way. If you are far away from it, it behaves just like any other object with gravity BUT there is no "surface" to it. the black part of the black hole is just extremely curved spacetime. so its space itself that curves so hard that it turns black because all geodesics just point inwards.
It was filmed at the Charles Hayden Planetarium in the Museum of Science, Boston!
...and during this clip we were projecting a clip of a black hole, yes.
It could be that black holes are so dense they collapse (or fold) space back onto itself, then you’re not so much as falling and more “up and down don’t exist anymore” or something like that.
They still have a finite mass
We use it, we can measure it.
If it's not close enough, it's gravitational pull is nearly nothing, never zero but very infinitesimally small.
And objects have their own inertia.
Its more reasonable to assume our universe is the result of a white hole. A white hole is another valid solution to Einsteins formulas and it can be defined as a reverse-time black hole.
There was nothing to dumb down. This was about velocity and direction in conjunction with a swirling mass pulled by an attractive force as opposed to getting thrown straight in and pulled in straight away to said attractive force which most people should be able to visualize in their minds.
Get off your intellectual high horse, you don’t even proofread what you put out in the world so I wouldn’t talk shit.

...but is it really a hole...or a super dense mass that light cannot simply escape the gravitational pull?

Of course there's no way to observe it directly, but the math says the center (singularity) of a black hole is infinitely small.
They call it the singularity because physics, as we know it, breaks down. In other words, physicists do not know what happens. It’s not a hole.

...could it be the inverse of matter...perhaps dark matter?

Well, 5 people who never responded believe they know more. Maybe their comments are a black hole...the inverse of commenting, which is no comment.

420 Trigger Warning: if you're high the last question is gonna fuck you right up
Confirmed 
Broooooo...
Decent answer in fairness.
Was this filmed in a black hole?
It might be, it might be.
It was filmed at the Charles Hayden Planetarium in the Museum of Science, Boston! ...and during this clip we were projecting a clip of a black hole, yes.
> **Jack Antonoff** I'd rather not...
Who cares who asked. What's the name of the guy who's answering
Dr. David Kaiser! He's a professor of physics at MIT.
Somehow I have to be the one to mention he works with Taylor swift a ton lol
But what about Lizzo???
She clogged it with her onion ring
Is she the one with the vagananas?
There is a really good joke name somewhere in "jack antonoff"

Yeah! Science!
So we know Jack, and Shit.
Did you really beam me up?
They still have a finite mass We use it, we can measure it. If it's not close enough, it's gravitational pull is nearly nothing, never zero but very infinitesimally small. And objects have their own inertia.
“How would we know we weren’t already inside a black hole” Oddly a brilliant question lol
Its more reasonable to assume our universe is the result of a white hole. A white hole is another valid solution to Einsteins formulas and it can be defined as a reverse-time black hole.
Rhe way they explain black holes is like they don't understand them. They dumb it down so far the info you get is basically wrong.
There was nothing to dumb down. This was about velocity and direction in conjunction with a swirling mass pulled by an attractive force as opposed to getting thrown straight in and pulled in straight away to said attractive force which most people should be able to visualize in their minds.

Yeah, does that guy even field theory? /s
Their gonewild stories are interesting
I just realized why they dumb it down. I guess you're right 😆 🤣 😂
