Spzi, in xkcd #2844: Black Holes vs Regular Holes

Falling in is only “definitely fatal” if it’s too big. For all we know, black holes can be tiny and light. We can debate if you can still “fall in” one of those. Maybe the process is more like passing by, or some mote of dust sticking to your clothes.

wahming,

Om nom nom

If "Indirectly" is an allowed answer, as demonstrated by the answers after "Precious Metals", then the answer to "Are regular holes created by the Big Bang?" is not "No."

‘Created by LHC’ is the best one here

did hawking really argue that all infomation in black holes is lost forever? what about the hawking radiation? idk im not really into physics

Look up hairy black holes. Hawking basically pointed out a paradox.

jalda,

For a long time, it was believed that Hawking radiation is thermal and doesn’t carry information, except for the mass/radius/temperature of the black hole.

In 2004, Hawking conceded that, due to the holographic principle, information wasn’t lost. The basic idea is that the infalling matter can gravitationally deform the horizon and thus modify the distribution of Hawking radiation from the pure thermal emission. And the interesting point is that the entropy of the black hole is proportional to its area and not its volume (holography), so the deformation of the horizon is sufficient to recover all the “missing” information.

its not like people follow the lanes in a roundabout anyway.

wahming,

That depends on which country you’re driving in

raubarno, in xkcd #2842: Inspiraling Roundabout

It will deadlock in the center because the car lanes are used for two directions. Unless you upgrade those unidirectional lanes into bi-directional pairs of lanes.

And it will still deadlock, so you have to put a round-robin semaphore in the middle.

Simpler solution, just add a bottomless pit or small singularity in the middle to absorb excess traffic.

Uli,

Sorry I’m late for work, I got sucked into a black hole again. No, I didn’t take a picture of the event horizon, you should just take my word for it. I wouldn’t even be late if it weren’t for the time dilation.

Welcome to Germany

Don’t tell the Americans, they’ll ban the Earth’s core! (somehow; maybe they’ll blow it up or something)

RizzRustbolt, in xkcd #2840: Earth Layers

I have a buddy that works in the HVAC layer. Good work if you can get it, but he says the commute is a real bitch.

I hope the guacamole layer doesn’t spoil. Guac goes bad so fast…

xusontha,

It’s replaced daily-thats what Chipotle does with the leftover guac

The guacamole layer is oxygen free, it only starts to spoil once it erupts on the surface.
