    along with sublimation I suspect that a good portion of the sulpher is being consumed and metabolized by microbial extremophiles. Given Mercurys proximity to sol one might be led to think photosynthesis would be to food of choice ,however there is much more habitable real estate below the surface in what I believe is referred to as a ''Mars analogy environment''

    Plasma cosmology ultimately denies Hubble's interpretation of red shift and from there they deny the Big Bang itself. To them the Universe is eternal. Lerner, Arp, and Alfven are the notables if interested.

    I did. The site I found didn't appear to be very authoritative. Planetary features being formed by space lightening seems highly unlikely to me. As for the other stuff I read, it seemed pretty straight forward in terms of the specific phenomena but I'm still unsure of what they're saying the theory tells us about the universe.
