I'm pretty sure he was referring to latency due to speed of light limitations. Satellite internet has very high latency, and there is no fixing it. 22,000 miles up, then 22,500 miles down
To meet girls. No other reason.
Tidal forces are the driving factor for maintaining a liquid core. Europa, Io, Earth, Titan, and now Mercury illustrate this. Mars is larger and closer to the sun than all these moons, but has no tidal forces. 1. Our own moon violates this rule (it should be heated by the tidal force of the earth). When all is said and done I think we'll find that the moon's core is, if not molten, certainly heated. 2. Venus has a liquid core I believe, and it has no companion, no tidal forces. Yes, I realize these statements contradict. Just throwing them out for discussion.
