It only weighs that much more than the sun, but is more dense. Still big tho
vowofloudness
Actually way less dense than our sun. Counterintuitive, but the bigger a black hole, the less dense. Schwarzchild radius for 6.5B solar 1/2
vowofloudness
masses is ~19B km, about 23 trillion times the volume of our sun. That gives it a density of ~0.45 kg/m3, about 1/3 as dense as air! 2/2

Size or mass if the sun?
bonnieyes1000cats
If a "naked" black hole, even a tiny one were to get close to our solar system our entire solar system would be disturbed,
bonnieyes1000cats
Even our sun would be destabilized and begin orbiting around the black hole. No way a BH could suddenly sneak up on earth.

Where does that entire galaxy end up? Like what’s inside that black hole? If space is a vacuum is a black hole a vacuuming a vacuum?

It ends up inside the event horizon of the black hole. And do you think that galaxy is made up of a vacuum?

The event horizon is the point of no return. Kind of like the edge of a waterfall. The point where the gravity is so intense there’s no ...

PballQhead
Just going to point out the "tiny black speck" is 6.5B times the *mass* of the Sun, not 6.5B times the *size*.
Blech7890
I thought it was referring to the size of the speck which is the event horizon, not the size of the black hole itself...
PballQhead
The event horizon is the black hole, the singularity is a separate entity inside the black hole. Also it has no size.
TisIChenoir

rylas
Thank you! This kind of inaccuracy irks me.
PballQhead
Did some quick math, 6.5B times solar size would be about 880 light-years across. Supermassive black holes are about 0.01 light-years across
IATTM
Humor me? Size is related to mass and is 3d. So not the right term to use, but "twice the size" for a sphere doesn't mean 2x the radius, -
IATTM
It's 2x the volume unless otherwise stated. Then you get into the mass compressing due to gravity, but still something to think about.
IATTM
But I do fully appreciate your explanation and it as a lot to the conversation with solid facts :)
PballQhead
"Size" without qualification (mass, volume, dimensions) is meaningless. To Pat Q. Anyperson off the street, it's generally dimensional, e.g>
PballQhead
a 100cm diameter exercise ball would colloquially be considered "twice the size" of an 50cm ball despite being 8x the volume/4x the surface.
vowofloudness
It's about 27,500 times our sun's radius, so ~23 trillion times its volume.
PballQhead
I was assuming most people would be thinking diameter; it ain't 6.5 billion times as wide for sure.
Muffyns
how much size is it comared to sun
ButteredNoodleDriver
The black hole itself? That doesn't have a size as by definition it is infinitely dense - it's essentially 1 dimensional, a point in space
Axianamos
Black holes are probably spherical. They compress matter as much as possible but its still compressed around something
ButteredNoodleDriver
From Wikipedia: "the singular region has zero volume"
vowofloudness
Very big.
Toffeeaccident
At least twelve sizes yes
Oblok
Something's not right here. 6.5B times more massive, 23T times the volume would make it less dense than sol. Isn't a black hole more dense?
vowofloudness
Weirdly, because gravity is an inverse square relationship, black holes get less dense as they get bigger. To make our sun into a black 1/3
vowofloudness
hole you'd have to crush it down to 6 km across. But with enough mass the density drops. If you filled our solar system (Pluto's orbit) 2/3
vowofloudness
with plain old air, it would be a black hole! And the one in M87 is more massive than that, so its density is about 1/3 of air. 3/3
zagibu
What is? The event horizon?
E4r3nd1l
No, that's a 1996 film with laurence fishburne and the first attempt at warp travel without a Gellar Field.

I love that it's pretty much accepted 40k cannon
E4r3nd1l
The writer admitted he was super into 40k while writing the script, so yeah, it's canon.

Yes; the Schwarzchild radius for 6.5B solar masses is ~19.2E9 km.

Thanks. The dude was called Schwarzschild, tough, but I know it's probably weird to have 3 consonants that all sound similar in a row.

derJake
Black Shield is kind of an awesome last name as well.
Baron29
It's the size of the actual core even knowable? The size of the EH is a product of the object's mass, isn't it? So the size is irrelevant?
JackBaler
there's no way to actually go in and verify, but it's commonly accepted that the core of a black hole is a singularity, an infinitesimally>
vowofloudness
Schwarzschild radius and EH are the same thing. We don't know what's inside, if there's even an inside, so EH is the only size that matters.

Black holes are capable of traveling at insane speeds and smaller ones NOT currently consuming galaxies are invisible to us as no light ½

Hawking radiation begs to differ

Essentially quantum pairings where one photon appears just outside the event horizon and the anti-particle of the pair appears within.

TheAssassinArtemisEntreri
Stellar mass black hole ejections happen when larger black holes consume another and is ejected from it's galaxy center by the collision

Yes, but the projected ejection velocities are also not that huge. But they are more massive, you are right.
stronomer
Or rather they *can* be more massive

Astrophysicist here! Nope, we'd have less than an hour's notice in the best case scenario- not enough for bare minimum rocket launch times.

That makes sense with the whole exponential effect of gravity with distance and the speeds involved. What would such an impact look like?
