>Black holes have an infinite amount of mass

>>9826612
How do they have infinite mass? Shouldn't it be a finite amount based on the mass of the star left behind after the supernova

>>9826647
You are correct, OP is retardo

Don't black holes have infinite density?

>>9826672
They don't exist.

>>9826612
>Infinite mass
Black holes have a finite mass which is higher than the mass than which a neutron star collapses . There is no way to way to prove black holes have infinite mass ,so your post is invalid.

>>9826672

no of course not, since they have both finite mass and finite surface( at least if you consider the event horizon the black hole and not just the singularity itself. In the second case there might not be a way to define any density)

>>9826612
>Black holes have an infinite amount of mass
no, they're infinitely dense like you

>A sun of 50 solar masses becomes a black hole
It gains infinite mass. kek

The universe has a finite mass. But it doesn't move...

>>9827281
That only disproves the converse of infinite mass -> can't move. You're just as retarded as OP

>>9826612
>Infinite mass
No.

>An object with infinite mass would be unable to move

Except you could make it move by just accelerating the rest of the universe. Now you have an unstoppable object hurtling through the cosmos, completely denying any attempts at making it stop.

>>9826612
Alright m8, the black holes can't move because of inertia, but that doesn't mean the space around the black holes can't move.

>>9826672
They dont have infinite anything, its gravity is just strong enough that light cant escape and this has lead to 5 decades of scientists being colossal fucking faggots that obsess over their inability to look at the fucking thing.

>>9826612
>are completely immune to force

>>9827394
lmao truer words

>>9827394
well actually a lot of interesting stuff (theoretically) happens at the egde and that is cool to study

>>9826612
They are constantly moving and can't be stopped more propably then. Their rotation is funnier subject.

Also it's bullshit.

There's actually an interesting discussion to be had here on inertia but since OP just is putting out some shitty bait, there's no reason to even entertain the subject

by taking the subject matter seriously you could have spawned an actual productive discussion
idk what the point of whatever this is was

>>9827689
It's also one of the few areas of the universe that's intense enough energetically that quantum gravity may come into effect.

>>9826612
You know how we spin around the sun? And our star system spins around the galaxy? And our galaxy spins around the universe? And our... etc.

Black holes definitely move.

>>9826647
Infinite density, not mass

>>9826612
Yeah bro they move

Black holes do have infinite mass because they have infinite energy so according to E=MC^2 an infinite amount of energy must be express as an infinite amount of mass. Prove me wrong.

>>9829807
And where does this infinite mass come from? Black holes don't have infinite energy anyhow

>>9829238
What is moving though? Maybe you're the thing that everything else in the universe spins around.

It's called relative movement

We just think of the bigger objects as nom moving.

Technically the center of the universe might be considered stationary.

Black holes dont exist only black discs exist. Since earth is flat then black holes are flat to. They also have infinite mass and energy and emit electric and manetic fields. Tesla showed that gravity dosnt exist , and would you rather belive some kike or a Tesla?

>>9826612
>Black holes have an infinite amount of mass
Black holes have more mass than the entire universe?
That's gonna need some backing up.

>>9829807
Black holes don't have infinite energy.

>>9826672
At this point i really dont give a shit

Black holes can and have been observed to increase in mass. So no op is not right.

They also decrease in mass. But most of you all knew this anyway.

>>9826612
Black holes have infinite density, not infinite mass.

>>9829807
Why do you say black holes have infinite energy?

>>9829807
Stop joking, or in case you are serious, go read the literature.

>>9826672
Singularities are a meme. Even if one assumes that a sufficiently large gravitational pressure overcomes any and all barriers and collapses matter indefinitely, time dilation also means that the collapse will never fully condense into a literal point.

>>9826612
Going for more grant money I see.

Besides the infinity mass and energy wich até both Impossible , dosent the lack of outside gravity and friction make the required energy for moving be allmost none making It possible to move even an object with not infity, mass but High condensed mass.

>>9826612
According to your logic the black hole would retain its spin and momentum from before it became a black hole, and would be impossible to change it's velocity.

>>9826612
>Black holes have an infinite amount of mass
no

>>9826612
>infinite mass

>>9830136
This is not how time dilation works

>>9826612
Black holes don't exist.

Fucking retarded physishits can't even define mass.
Nima Arkani-Hamed (and others like him) was giving me the impression that he might "get it" at some point, but nope. The whole edifice of physics is built on sand.

If black holes have infinite mass then their gravitational pull is infinite because of

F=G(m1*m2) /r^2

Regardless of distance

>>9829807
I see a universe of infinite energy but not potential for threat from this enemy

they move space around them

>>9826672
>>9829241
>>9830124

Sorry, pleb cross-boarder here, but I thought that density = mass/volume.

Therefore, in order to make density = infinity, thus ∞ =m/v, therefore m = infinity and mass of a black hole is infinite.

So, wouldn't this also give Black Holes infinite energy due to E=MC^2, as pointed out by (>>9829807).

>>9831657
Exactly! I don't get all these retarded anons trying to prove the impossible

>>9831673

My assumption is that the density of Black Holes is not truly infinite, but is only asymptotic, or is similar in magnitude to infinity for practicable purposes.

However, despite this nuance, following from these assumptions, I imagine that when science journalists and science popularisers try and teach science to the asses of the masses they simplify these concepts in order to avoid confusion.

>>9826612
>Black holes have an infinite amount of mass
False. Black holes have infinite DENSITY.

>>9831680

That being said, I don't know either way, this is just speculation due to my knowledge of twelfth grade physics not being enough to solve OP's problem.

>>9831681
I'll summarize it for your retarded brain anon:
> infinite density
> d=m/v
> infinite density by definition requires infinite mass
> E=MC^2
> Infinite mass by definition requires infinite energy
You are free to feel stupid now anon, go ahead

>>9831690
this is true, also remember that black holes can be made from energy so intense that it infinitizes itself, the known Kugelblitz

>>9831690
How do you measure volume?

>>9831690

Holy shit that fucking image, I'm dead anon.

>>9831690

You know, the funny thing is, the poster could just be very very intelligent, and capable of visualising and retaining all of the information from the textbook in his mind.

>>9830700
Theyre onto something, but the whole state of it is reminiscent of the ultra violet catastrophe, just at a far greater scale. So much of its predictions are wrong, or impossible, its really only the safe assumption to make.

>>9826612
Black holes don't exist.

>>9826612
Black holes are an illusion caused by space expanding

The concept of two black holes merging does not make sense, nor does the idea that anything which has fallen into a black hole can somehow increase the mass of the black hole, cause that would mean information is not trapped inside the black hole contrary to claims.

>>9832313

uhm the mass of the black hole does not transmit information. So nope , nothing violated there.

>>9832345
You're literally being retarded though.

If the mass increases, this transmits the information that there is extra mass that has been introduced to the black hole. The kind of information you're talking about is a brainlet black hole. If I drip a drop of water into a bucket of water, you can't tell which was the drop I dripped, and cannot seperate my drop from the rest of the water in the bucket.

>>9831690
>infinite density requires infinite mass.

You monumentally retarded nigger. You could also achieve infinite density by infinitesimal volume.

>>9832313
>cause that would mean information is not trapped inside the black hole contrary to claims
Except literally no one has ever suggested that black holes eat all information because that would violate observation. And a more modern understanding of black holes preserves information.

>>9831657
>Therefore, in order to make density = infinity, thus ∞ =m/v, therefore m = infinity and mass of a black hole is infinite.
The singularity is infinitely dense because its volume is zero. The entire black hole -- everything in the event horizon -- isn't infinitely dense.

Black holes don't exist you stupid niggers.

>>9832406
Infinitisimal volume would mean nothing can actually enter a black hole though, and the only reason we can't see them being because they are submicroscopic rather than light doesn't reflect off them, which means the pop-sci artistic depictions of black holes are wrong by presenting a black silhouette sphere. The warping effec would remain, but there would be no black silhouette.
