Astronomers Find a Diamond the Size of a Planet.

In other news, DeBeers pioneers interstellar flight in record time.
Hehe... that would actually fit their bill nicely. Guess who was a founding member? Cecil Rhodes. Yup, the money-making magnate who essentially conquered a good deal of modern Zimbabwe and neighbouring countries for the Brits.

Hell, let's start calling the planet "New Rhodesia" :p

It says it has roughly the same mass as jupiter... does that mean gravity on the surface of diamondworld would be the same (about 2.6g)?

Ouch. No Crash landing on that planet. I mean you "could crash landing" on earth and might able to get away, but on diamonds?

Assuming that diamond planet is completely solid, I'm getting about 11X er, about 7X the gravity of Jupiter... it's been a while since I've had a physics class, though.

What could possibly go wrong with a ship mining resources of a planet?

Naaaaaaah. ;)
It can turn into a boring game with lame jump scares that everyone but me seems to like? [insert fade hate everything joke here]

Or maybe John Wayne can smash it with the bottom of a beer bottle, demonstrating a complete ignorance of the difference between "hard" and "not brittle". Also the writers of X-Men and anything where diamond is used as a shield.
 
Mass, not volume. It should be the same gravity, if we go by Newton's law.
The key is that we are trying to find the surface gravity. You are correct, the mass is roughly the same, so the pull of gravity is the same at a given distance. The distance from the center of mass is determined by where the surface is. For a planet with roughly the mass of Jupiter and a radius of no more than 30,000 km[1], the surface gravity would be at least 14g[2]

Good point, herp derp >_< I forgot the distance variable. *smacks self*

It was in reference to the coal-black planet thread that was recently posted. The one where everyone was making tongue-in-cheek references to the "blackness" of the planet.

Also, I have absolutely no idea what your post means.

In any case, it was pretty stupid in retrospect. Deleted.
 
Oh my bad. I didn't read that thread. It just seemed out of left field and uncharacteristic is all. The context makes it kinda funny actually.
