Interesting that smaller black holes exist throughout galaxies and orbit the massive central black hole.

Dunno...but Obama took up quite a bit. /s

Article says that a black hole the mass of the earth would be the size of a ping-ping ball. Another that had the mass of the sun would be about 2 miles in diameter.

Amazing!

There are many unanswerable questions one could ponder.
“How many Angels fit on the head of a pin?”
“Is a Black Hole an example of the String Theory?”
“Does light energy have weight in and of itself?”

“What are the 7 Elements of the Earth?” (This one does have an answer).

Cuomo’s black hole of death in New York is taking up a lot of space... And creating a lot of senior citizens deaths.

Well, one filled up the White House.

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.

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.

Mass, size, weight, volume...

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

African or European black hole?

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?

called Sagittarius A* —

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