Life on earth has most likely developed by a combination of sunlight, shallow water and volcanic activities that make all kinds of chemicals. But on waterworlds things get a little complicated. Life m...

In the pessimistic scenario, let's imagine a sphere 20 meters in radius. That's Cd=0.4 and D=20 meter. A detcord 340 meters in diameter. Now this is an asteroid: Low density = high surface area, spher...

Combining the the three formula will yield this: R=(3c^2/8rhopiG)^0.5 Which means the radius will be three OOM larger if the density used is 6 OOM smaller. 12.7um it is.
