BTW, did you hear last week that science is actually unsure of the origins of clouds and new theory suggests they originate from Cosmic rays, not entirely from dust nucleation sites in the atmosphere? I thought that science was "settled" long ago.
The words "science" and "settled" probably should not appear together in a sentence. There always seems to be some little complication hiding in the details, such as the cosmic rays you mention, which are affected by the solar magnetic flux, which is somehow tied to the sunspot cycles, which may be in their turn tied to tidal effects from Jupiter and Saturn.
We never run out of things to study. That, at least, is settled.
