Almost looks like what'll happen to a wall if you give a red marker to a little kid.

Made me think of some sort of bloody monument a species of spacefaring conquerors might leave.

(Did some back-of-the-envelope calculations out of curiosity and found that the amount of blood in the current human population would be sufficient to paint a surface area roughly the size of Germany. I wonder if any grimdark Warhammer 40K story featured such a thing.)

TIL: Tethys might look like a moon, but it's really a shrine to Khorne.

A shrine to the Shrike!

Maybe Banksy's gone further than we suspected...

Why are almost all impact craters perfectly circular?

dweinus• 11 years ago

I'm not a physicist, but I would hazard:

it would require a very non-spherical object to create an a-circular crater because ground resistence forces material to move primarily parallel to the surface of the planet/moon, which tends to regularize the shape. Any atmosphere will make the impacting object more spherical through resistance. Lastly, large bodies in space tend to spheres naturally as their mass converges by gravity.
