If you could fit a million earths into the sun and 6.6 billion suns into the new giant black hole, you could fit 6.6 quadrillion earths into the new giant black hole.
And if there are 6,893,355,380 people on earth right now, and each earth had that many folks living on it, there'd be 4.5 septillion people there.
Of course, most of those folks have Facebook accounts--500 million per planet, actually. So that's 3.3 sextillion Facebook accounts. In digits, that's 3,300,000,000,000,000,000,000 Facebook accounts.
Now, since all these people with all these Facebook accounts happen to now be living inside an enormous black hole, one can imagine they're not too happy about it. So unhappy, in fact, that you'd be lucky to find one in 10 whose status update is something positive and not "omg fuckin blackhole life sux" or something.
So that's only 330 quintillion happy Facebook people, at best.
But given that they're stuck in a godforsaken black hole, that's still a lot.
Plus, the the other 3 sextillion unhappy folks would come around eventually. Simple math says it's inevitable.
