Anyone that claims a real-world phenomenon is caused by "the number infinity" or "a 1 dimensional point" is trying to blow smoke up your ass.

>>15336616
I agree but maybe its not meant to be taken literally and is just an expression of a really large number?

>>15336604
what is it about black holes that makes them the number one most popular popsci topic of discussion amongst the brainlet soience fangoys?
is it the comic bookish aspects of the spectacular, unrealistic and completely non disprovable conjectures which go along with the topic that make black holes so popular amongst the scientist posers and wannabes?

>>15336616
I wouldn't quite say black holes are caused by infinite densities or singularities, but rather those are predictions of math allowed solutions to some GR equations. Whether or not they accurately describe reality is beyond me, what I do know is a lot of their predictions have been observed.
That said we also say like electrons are point particles and shit so whatever

>>15336618
Black holes only "exist" because people use math around infinity and 1d points. Without that nonsense idealized math they disappear from reality entirely and can't exist.

>>15336604
Because they are very cool and even laymen/normalfags can see this without any mathematical or physics-related knowledge.

Nice copypasta

they're cool because they're scary, and they're scary because they're black

any claims that they "are caused" or actually exist, yet use nothing other than negation to define "it" should be laughed at. Observe the examples of the negation used by shadow chasers here:

Cool story bro. One more "not" and you could tie a rope and hang yourself from it.

I FUCKING LOVE BLACK HOLES!!!1
IMMMAA GOONA TIME TRAVEL IN MUH BLACKHOLES
JUST LIKE THE HEROES IN MUH MARVEL COMIX MOOOVVIIEESS!!!
I'M GOONA TELEPORT TO THE MULTIVERSE IN MUH BLACK HOLE!!!!
BLACK HOLES ARE THE STRONGEST THING IN THE UNVIERSE!!!
I AM STRONG BECAUSE I KNOW ABOUT BLACK HOLES!!
MY IQ IS SO HUGE
I KNOW ABOUT THE UNIVERSE!!!
SPACE IS BIG AND STRONG
LIKE MEE!!!!!

Soijaks get into science, turn it into soience. Soience doesn't sound like science anymore, rather like soience.
Solution:
Kick out all soijaks, let only right-wingers do science. Problem's weren't.

i think it's cool because it's a natural progression from neutron stars. okay, with enough mass you can ignore the pauli exclusion principle and force electrons into the nucleus.
naturally, then, with enough mass, you can force those neutrons into each other. that's very neat.
or on a more classical system, how you could compress a gas into a liquid. or into a solid. it's only reasonable that you could take it further with greater force.

Have some more science.

Very low iq opinions

I don't think people who know what they're talking about are claiming they know how it all works. It's usually people who don't know anything that think they know everything. Scientists explore what the mathematics allows and from that create theories or vice versa and these theories are tested as technology and financials allow them to be tested, kind of like forward planning, like instead of waiting for the funds to run tests and then working out the theories

Consider the point. The mathematical point. The point has no dimensions. Attempting to insert this concept into physical reality is difficult, it does not matter how closely you approach a point, it can never be reached. The point is a mathematical construct which we assumed had no basis in physical reality. Until black holes. It appears that black holes are indeed a physical manifestation of a point. This is mind fucking shit, even if it proves to be wrong. How do you map 3 dimensional space onto a point? Fucking brain meltdown. You should be happy there are clever people out there trying to blow your mind because its the only blow job you will receive ( your grandfather doesn't count )

Because it's a context in which the most absolutely basic fundamental assumptions of what reality is like cease to function and we can only wonder and speculate 'what's on the other side'. It's off the edge of the map where there might be dragons.

>Scientists explore what the mathematics allows
oh mathematics huh, can you explain it in terms of morphisms, functors, and classes for me? As a mathematician in the year 2023 I can only do math on phrases, sentences, and vocabulary definitions now.

Due to their nature, black holes can't be directly observed or measured or studied. All the "science" is complete supposition based on mathematics derived from our current understanding of the laws of physics in the Universe.

Of course it's going to sound like nonsense.

Way too intelligent post for this board of squealing spasmotards. Fuck off.

>what methods are likely to be available to persons with devices allowing them to engineer worldlines?

>>15337584
why do "scientists" insist on making conjectures and presumptions about things which they know are not confirmable or deniable via observation?
>Of course it's going to sound like nonsense.
it doesn't sound like nonsense, it is nonsense.
the scientific method turns on falsifiability, without that aspect, the conjectures do not make sense AKA nonsense.
"trust me, i am very smart" is not a rational argument. it might work with the peer review committee, especially if they all use the same argument in their own publications, but that does not make it scientific, it lacks the rigor of the scientific method. these "scientists" all know this, they just don't seem to care about the constraints of the scientific method. that being the case, they are doing something other than science, what is it? is there a name for what they're doing? the name "science" is clearly out of the question, for the aforementioned reasons. why are these people so willing to flush hundreds of years of tradition of rational scientific investigation down the toilet in order to pass their conjectures off as scientific?

>>15336789
How can you not think they're cool? Just because laymen think they're cool for their dumb reasons you MUST be contrarian and think they're dumb?

Earth is flat with a dome. Black Holes don't exist.

Black holes are arguably the weirdest objects in the universe. They're weird because we think we have an excellent understanding of what happens outside the event horizon, but no understanding at all about what happens inside it —if anything, even. There's a theory called complementarity that says, among many other things, that an observer who falls through the event horizon and a distant observer who's watching it happen will disagree *maximally* about what occurs. The distant observer sees the infalling astronaut get time-dilated and red-shifted until he disappears before reaching the event horizon (and his information is "smeared out" over the entire area of the event horizon), while the infalling astronaut experiences …something else entirely, we don't know what. It's possible for these two observers to disagree about fundamental things because there's no way for them ever to get together and compare notes, since the trip through the event horizon is purely one-way. We can only ever speculate about what goes on beyond the event horizon because we can never go there and observe and report back to the greater universe, and speculating requires a more advanced theory of gravity than GR, possibly a quantum theory of gravity.

So outside the event horizon: pretty well understood, we think. Inside the event horizon: complete mystery about which we can't even make any guesses yet.
