how stupid are you. there are much smaller in diameter black holes than an average neutron star.

have you even heard schwarzschild radius?

it has a radius of 12 km and it has 3.8 times more mass than the sun. it cannot be a neutron star.

>>9339936
And do you have any observations to show that it is actually 12 km in radius? We have yet to observe the event horizon of any supposed black hole.

>>9339926
They're not neutron stars, they're Planck Stars.

>>9339963
you can calculate it by analyzing orbits of multiple stars orbiting around black hole, gauntlett explains it here quite nicely with the actual video of the center of our galaxy.

just watch a few minutes.

also it's explicitly measured in 2012.

Whatever that means...

>They are actually neutron stars but with enough mass that light can't escape.
Past a certain amount of mass, neutron stars collapse into into singularities.

My grandfather’s name was Hammus. His face was scary ugly. We called him Heinous Anus. My siblings and I didn’t know what we were calling him until I reach high school and realized what we where calling him. I told my brother and sisters. We were all horrified. Nobody in my family seems to know who named him that or why EVERYONE called him that. At his funeral last year my cousins were telling stories about Heinouse Anus at the church. WTF??! I asked if they realized what they were calling him. Everyone we confronted had a similer reaction. My Uncle could not wrap his head around the fact that the WHOLE family referred to his dad as HENIOUSE ANUS for fucking years and years! He just kept shaking his head with his whole face furrowed repeating his name over and over again in disbelief and disgust. I tried broaching the subject with my mom after everyone started asking questions about his nickname. She cut me off at Heinouse, then acted like that name was never to be spoken out loud. But she herself called him that!

Can’t believe we all called him that to his face. HENIOUSE FUCKING ANUS was my grandfather!

neutron stars are extremely dense and extremely small, much the same as yourself.

anyway since we cant see inside a black hole it's irrelevant what is inside them. It's either near-infinite energy, or it's a place without time and no movement so no energy. either way if you fell into one you'd die instantaneously at the event horizon.

No, it's not.

>or it's a place without time and no movement so no energy.
No, it's not.

Black holes have a finite and measurable mass, and thus energy. Maybe you were thinking of infinite density?

>either way if you fell into one you'd die instantaneously at the event horizon.
Not necessarily, and probably not exactly at the event horizon anyway.

>muh supermassive black holes at the centre of galaxies
You do realise that the scales where's talking about here are in the region where GR is provably no longer a reliable theory, right? This is all circular, speculative fudging.

(I am not OP; but he seems to have copied and butchered some of my claims.)

What scales would those be? You've never studied GR, have you?

if its a self contained star generating energy that cannot escape, it's near infinite energy. It's a closed system that feeds back into itself. You have mistaken the fact thst it has mass with the fact it does not lose mass, unlike stars that radiate their energy away.

>>9341434
this was the dumbest thing i've ever read

Neutron stars cant be stable enough to do that

>>9341636
actually they can if they spin fast enough, do the math before you spout bs

>>9341627
>if its a self contained star generating energy that cannot escape,
No, it's not. It has exactly the mass and energy of the material that formed it and fell into it. It isn't "generating" any energy because it isn't doing fusion any more. That's why it collapsed into a black hole.

>it's near infinite energy.
No, it's not.

>You have mistaken the fact thst it has mass with the fact it does not lose mass, unlike stars that radiate their energy away.
That doesn't even make sense.

Stop pretending that you know anything about black holes.

Lol. You sound actually retarded. Seriously.

Look at your picture, mass inflow is way bigger than its hawking radiation.
