Re: Tardigrades will Inherit the Earth

They already have, that's the point, and it was long long ago. We're just squatting.

Is this like the infinite series of (+1 -1 +1 -1 +1 -1...) which equals 1/2?

Re: Even if we could get there, somehow

Alas, 7 times the mass, but only 1.4 times our radius make for a very much denser body. Gravity drops at the square of distance so the 'surface gravity' will be nearer 3 times that of Earth's.

New satellites could cause catastrophic space junk collisions

Re: The real problem is the thousands (millions?) of pieces of space junk we can't see

Most (all) Satellites are going the same way, who would put up an LEO Sat going backwards (retrograde), so the relative speed of collisions is lower than you'd expect.

If you could charge your Sat to feel the drag of Earth's magnetic field, you could also use said charge for manoeuvring, which we can't or we'd already be doing that.

Sorry to poo-poo :-(
