a cosmic hug is better than no hug at all.

But I'd urge people to draw the line at the Dark Side.

The black hole at the center of the Triangulum Galaxy has a mass that is no more than 1,500 times the mass of the sun. Its spiral arms are loosely wound at an angle of 43 degrees. Credit: NASA/Swift Science Team/Stefan Immler

The huge black hole in the heart of the Andromeda Galaxy is about 180 million times the mass of the sun. Its spiral arms wrap around the galaxy bulge at an angle of 7 degrees.

Clever. I wish I had thought of that.

Big deal, that's only 60 trillion Earths.

This is more scientist mumbo jumbo like evolution. 10,000 years ago the universe was created by a big invisible guy in the sky. He spoke magic words and made everything.

Not very convincing. Try this:

Wonder where a black hole goes to... maybe you go in one hole and come out ANOTHER in another galaxy..

The tightest embraces came from galaxies boarding with the biggest black holes, such as the Andromeda Galaxy (its central black hole weighs about 180 million solar masses),

Headline, “Black hole puts strain on Andromeda.”

Say, didn’t they make a movie about that?

Where did the matter come from originally? How can time or space be infinite? How can they not be infinite?

Aren’t you so smart and smug with all the answers!

Yup... otoh, maybe it goes nowhere, a claustrophobic person’s worst nightmare... It’d be like getting sucked into a piece of vermicelli, down to the very tip, then they dump the mass of a billion Earth’s in on top of you... I CAN’T BREATHE!!!

If you could see inside a black hole you would see single, unmatched socks orbiting the singularity. And you wondered where they went.

A black hole is the evolutionary endpoint of a star packing at least 10 to 15 times the mass of the sun. Once the fat star has burned out, there are no outward forces to oppose gravity, causing the star to collapse in on itself. The stellar remnant eventually collapses to a point of zero volume and infinite density (called a singularity), and nothing, not even light, can escape its clutches.

And there is only one per galaxy?

No, probably millions, most small potatoes compared to what lurks at the centers of galaxies. Many astronomers believe there is a supermassive black hole (except in cases of recently merged galaxies, in which case there may be two or three supermassive black holes that haven’t merged yet) at the center of each (large?) galaxy. This is an area of active research and they’re still trying to confirm the claim. These big boys can have anywhere from a few million to a few billion solar masses, far outweighing a typical black hole that’s formed in a supernova explosion.

That doesn’t seem to accord with the description in the article.

Why do you say that? Seems pretty consistent to me. But maybe I missed something?...
