Read this excerpt from A Black Hole is NOT a Hole. 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.

nowadays, 93% of the arab population is muslim, which at the same time is subdivided in sects including the sunni, zaini, alawi, shia. the remaining 7% is composed mainly of christians.
