How much space does a black hole take up?

So, we have the answer to the titled question, "How much space does a black hole take up?"

The answer is "Bermuda." 🌌

Earth, Wind, and Fire is my guess.

[DoodleBob]

Earth Wind and Fire with Chicago.

The only essential elements missing in that pic are Zappa, Who, and Rush. I will accept Hendrix or a good punk band like the Dead Kennedy as substitute isotopes.

[Still Thinking]

Definitely not ELO.

The larger the black hole, the less dense it is. A super-massive black hole can have a mass density less than water. Obviously such a density could support life and it might be possible to mosey on in without being destroyed. These black holes could be home to the most ancient and advanced lifeforms in the universe. You can check in, but can never leave, or even phone home.

At the center of a black hole is believed to be an infinite gravitational well in the fabric of spacetime, called a gravitational singularity.

Nothing is infinite in the real universe. While infinities are common in the abstract universe of math, they just indicate failure points where the math models cease approximating the real world.

Depends on the size of the peg.

The article reminds me of this:

Hilarious article. Works kind of like this:

1. Ask how large black holes are

2. Provide lots of background information about everything other than volume

3. Go to 1.

To find the answer to the question I searched on the word miles, and found it in the 13th and 15th paragraph. (one is 10 and one is 578 miles in diameter). Then you get another size measurement for progressively larger black holes every two or three paragraphs afterwards.

No kidding, or STYX.

[servo1969]

As much as it wants.

[alexander_busek]

Black Holes have a measurable circumference, but no definable diameter.

Technically, if they actually existed, none. If you’re counting the event horizon, that varies.

[TheZMan]

Mass, size, weight, volume...

Just pick one at random, as needed, and throw it in the article. No worries.

[DannyTN]

African or European black hole?

[Beowulf9]

So, if eventually all the universe collapses and becomes black holes, say there is for some reason then a reaction, an explosion of these black holes and then = stars,, planets...a universe is created.

The Big Bang..again?

[NTHockey]

Density is mass divided by volume. If the density of a black hole is infinite, the volume must be zero.

The movie “Interstellar” is great. They spend a brief interval on a planet just outside the event horizon, and find 22 years have elapsed on the orbiting craft that launched their probe.
An astronomy book my older brother had turned me into a space nerd before I was 10. I got dizzy reading a passage about the limitlessness of space, and the temperature of stars as “trillions of degrees”. That hooked me.

Tell me the A* is not a-hole....
