Talking about black holes today, nerds, and understand black holes, we have to get our heads

around a basic understanding of the universe that black holes find themselves within a universe

that contains, well, everything.

The universe includes all of space and all the matter and energy that space contains and

includes time itself.

And of course, our galaxy, the Milky Way and the Milky Way includes Earth, you, me, and

everything you've literally ever seen or read about, everyone you've ever known, alive

or dead in some form.

And the Milky Way is but one of billions of galaxies in the observable, known universe.

And virtually all of these galaxies, including our own, are thought to have supermassive

black holes at their centers.

All the black holes and all the galaxies and everything else, all part of the universe.

And the portion of the universe that exists outside the confines of our planet's atmosphere

is so damn close to every single one of us all of the time, weirdly close, if you think

about it.

Wherever you are right now, outer space is never much more than roughly 62 miles or 100

kilometers away.

If you're on the top of a tall mountain, you can subtract a few miles.

If you're for some reason, deep down in some trench in the ocean, well, you're probably

in a lot of trouble and you could add a few.

It's so close, day or night, whether you're indoors or outdoors, asleep, eating lunch,

closing off in class, outer space, just a few dozen miles away.
