Catch22,

Quite true. Irish, in a different thread, said much the same thing.

There are, I have read, areas on the sea bottom liberally covered with mineral nodules. I wonder what caused that. An ecosystem NOT based on photosynthesis was recently discovered near volcanic submarine vents. If not an alien ecosystem, it does, at the very least, warrant reexamination.

I’ll admit that my preferences are towards exploring outer, rather than inner space, but I wonder if there is a balance point in these various expenditures, and if there is one, what it might be.
