I've recently been reading quite a bit about the theory/facts noted above for the cosmic dust we're constantly and endlessly coming into contact
with. University and other solid sources have been talking a great deal in the past month about establishing water in current atmospheric samples ...
not ancient past theory, coming from extraterrestrial dust.
Just to give everyone a warm and fuzzy thought to go to bed with? I did some real looking into this a couple nights ago, in fact, as the 'Doh!'
moment struck me..Earth is nothing like a 'closed' system, as it's so easy to presume.
Anyway... it takes Earth 250 million years..give or take, to make a full orbit of the Galaxy and whatever is at the center of it. (a lot of exciting
stuff there lately too, but I digress)..
The thing that is most relevant and ought to really give happy thoughts is that over that 250 million years, and given different speeds of things in
the Galaxy, our Solar System is moving through the "arms" as it's going above and below the denser plane region in a regular gyration. Cycles in at
least 3 distinct ways, interacting ....and going by most 'best guess' renditions of "You Are Here!" maps of the Milky Way right now? We're either
on the edge of an arm, or right on/into the edge of a 'spur' or short (in space terms) stretch of denser space.
If that dust can become denser as well as other things that give those arms distinct mass overall from interstellar space? Well, just what DOES a
"Space Rain Storm" look like? It seems, based on recent discoveries, that very event may at least be possible from the past ..and future?
Gotta love the topics that come up on ATS.
