There's a joke in there but I'm too tired to think of one.

Are you saying that you're currently too dense?

That's probably the worst article I've ever read on fark.  It's basically some guy rambling as if he's a geek who just smoked up and got a little stupid.

So.  Which one of you farkers was it?

After all, Einstein showed us that energy and mass are equivalent. Grab two atoms of hydrogen and mash them together hard enough and some of their mass will be converted to energy. So, if energy and mass are equivalent, why can't energy create a black hole?

Only God can make a tree, man.

Wish this were true for me. I'm expecting maximum levels of the stupids, it is Monday after all.

What the f*ck is up with these i09 "articles" lately that "report" nothing other than "some say that if X happens, Y will follow; wouldn't that be awesome"? with no backup data or facts at all?

i09 has always been that way.

I would be shocked only if they managed to submit their garbage without plethora spelling errors.

All that's required is a sufficiently powerful Buster Machine, the planet Jupiter and a Degeneracy reactor detonation.

I feel a lot dumber having read that. And the last paragraph alone shows, through bland humor, that he has no farking clue how black holes work. Even if you could form a black hole with some photons if would immediately "evaporate" away via Hawking radiation and your body would still have vastly more gravity than it does.

FTFA: "That point has, technically, no volume, but it has infinite density"

I am pretty sure this isn't factually correct.

Where does an Illudium Q-36 Explosive Space Modulator fit into the equation?

That's what the math says. Black holes have a finite diameter but an infinite radius.

The best way to turn light inside out is to swap the wires on the light switch. Off is On, On is Off.

You can also rewire the porch light to the front hallway, but don't do both of these things because they'll cancel each other out, and you'll end up with a white hole, which is not nearly as fun as you'd expect.

The term "kugelblitz" goes back to Wheeler's 1955 paper on geons.  The idea was to think of "particles" as gravitationally-bound balls of energy.  However, they weren't black holes (possessing event horizions); they weren't even stable.  There are solutions of Einstein's field equations that have black holes with infalling electromagnetic radiation (like the Vaidya null dust), but I don't know if there are any solutions that show a black hole forming in the first place from nothing but electromagnetic radiation.
