Okay. Here, to me, is the primary difficulty with hollow Earth thinking:

It is hypothesized to have plants and life, therefore there is light. Some of the h.E. theories I've read claim that there is an "inner sun". Now, to have an actual sun, you need MASS, and lots of it for the fusion and fission reactions and recombinations. Jupiter -- a gas giant -- is not massive enough.

Yah, I know, it was theorized that it could be "kick-started" into being a sun, however I have to seriously doubt that. It simply lacks the mass. Our own sun, Sol, is really a very very dinky sun in the universal picture. I'm not certain if there are any known stars smaller than our own -- I'll check on that later.

Anyway, this is the crux of the problem. I admit, it's intriguing some of the evidence that points in that direction. I could get onboard as a possibility, if not for the inner sun thing. Just can't fit inside the diameter of the Earth. Can't.
