An artist's conception of stars moving in the central regions of a giant elliptical galaxy that harbors a supermassive black hole

They're huge. They're voracious. They're blacker than a panther on a moonless night. They're black holes, the mind-bending, space-warping cosmic objects with gravity so insanely powerful that even a beam of light that wanders too close will be sucked in, never to emerge. Einstein's theory of general relativity predicted they might exist, but the great physicist himself doubted it would really happen.
Einstein was wrong. Over the past decade or two, black holes have been discovered all over the place — small ones peppered around the Milky Way and huge ones, impressively called "supermassive" black holes, lurking the centers of galaxies. The one at the core of Milky Way weighs as much as a couple of million stars, and it could swallow the sun without even noticing, the way you'd swallow a pistachio.

I hate Artist's conceptions.
"We shall not cease from exploration
And the end of all our exploring
Will be to arrive where we started
And know the place for the first time." -- T.S. Eliot.

As they gain mass, they might exert enough gravitational pull to slow down the expansion of the universe and possibly reverse it, condensing matter into a small point, until it reaches a critical mass, then big bang all over again.. of course this is pretty theoretical, but its mind blowing to think that this cycle may just be endlessly going and going and going, with reality essentially being re-created over uncountable eons going back to infinity

it just gets compacted, its a giant ball of mass/energy essentially. the mass to size ratio is incredible.
black holes are formed when a star collapses on itself
just some info for you brahs

Pretty crazy to think of. I still find Supernova's slightly more interesting (such shear power), but then you have basically the antithesis of that in blackholes
Analytical chemist, feel free to PM me chemistry questions. If its lower level chemistry, pretty good chance I've forgotten how to do it though.
