Introduction
Have you heard the news?
In outer space, mysterious entities called black holes seem up to no good.

From the headlines, you’d think black holes were beasts with endless appetites, lying in wait for the next meal. By some reports they are “runaway,” out-of-control “predators” that “feed” on galaxies, only to “belch” and “spit out” what they don’t eat. They “lurk” in the shadows, “mangling” stars and “gobbling” them up. In short, they have a nasty reputation for being monsters “gone mad.”

But you know what?

A black hole isn’t a monster. It’s not even alive. That means it can’t lurk, eat, or belch. It has no dark, destructive desires.

Of course, you may have already figured this out. But you know what else?

A black hole is NOT a hole —
at Least not the kind you can
dig in the ground
or poke your finger through.
You can’t just walk along
and fall into one.
A black hole isn’t a hole
like that.

If a black hole is not a hole, then what in the universe is it?
