OT: For space-y and science-y nerds - the Milky Way's black hole has been imaged

I don't know the scientific details, but the Event Horizon Telescope (EHT) is a collection of 11 radio telescopes around the world joined together to image black holes.  It was used to collect thousands of radio images of Sag A* - the supermassive black hole at the center of the Milky Way galaxy, our very own black hole!  Some of the images were released today, including a video animation, showing the black hole for the first time in history.

No word yet on whether Michigan's 2017-2018 OL has been found...

This is where you can find the black hole when looking at the sky:

These are the radio telescopes used:

This is our black hole (kinda looks like... well, nevermind):

Here is the link to the animation.  There is far more interesting news about this here, because I just some local rando interested in such items that doesn't actually know anything about them!

I'd say an inflamed asshole (no, not Mark Dantonio). But I'm really curious what you wanted to say there.😊

Anyhow, this is really really really cool!

It is so fascinating to know that all the matter in our massive galaxy revolves around a very large irritated butthole. 

Science is amazing...

black holes are crazy cool and if I didn't hate physics so much as an undergrad, that's probably what I'd be studying in my professional career.

As matter squishes down under the immense gravitational weight of a collapsing star, it meets resistance. The discreteness of space-time prevents matter from reaching anything smaller than the Planck length (around 1.68 x 10^-35 meters). All the material that has ever fallen into the black hole gets compressed into a ball not much bigger than this. Perfectly microscopic, but definitely not infinitely tiny.

This resistance to continued compression eventually forces the material to un-collapse (i.e., explode), making black holes only temporary objects. But because of the extreme time dilation effects around black holes, from our perspective in the outside universe it takes billions, even trillions, of years before they go boom. So we're all set for now.

So, the creation of the universe (big bang) could technically be the explosion of a massive black hole that swallowed the "previous" universe

This, uh, sounds pretty hokey.  As conjecture it may be plausible conjecture, but we don't have an equation of state for the inside of a black hole because, by definition, we're unable to directly observe it.  And since this theory says it can't be verified anyway due to the time dilation, it might as well have added unicorns into the mix.
