Now, our Sun will not collapse to a black hole. It's actually not massive enough.
Sentiment: NEGATIVE
Proof of the black hole is a tremendous amount of mass inside a very small volume. There's 4 million times the mass of our sun within a region that's comparable to the size of our solar system.
An ordinary black hole is thought to be the end state of a really massive star's life.
As an astronomer, I get to ignore the details of the things that we don't understand. There's a lot of work that we can do on scales that we do understand, and there is actually a finite size that I can associate with a super massive black hole.
Black holes destroy any objects that happen to fall victim to their gravitational pull.
If the sun comes up, I have a chance.
A big misconception is that a black hole is made of matter that has just been compacted to a very small size. That's not true. A black hole is made from warped space and time.
The sun's going down and we can't afford to come back to it tomorrow.
Black holes are pretty scary when you ponder them. They seem nihilistic, infinitely destructive on an inconceivable scale, notwithstanding the ideas of Hawking radiation.
The key to proving that there's a black hole is showing that there's a tremendous amount of mass in a very small volume. And you can do that with the motions of stars.
Finally we shall place the Sun himself at the center of the Universe.
