Meteorite's tiny secrets reveal Solar System's sodium-rich, alkaline liquid past – a clue to formation of life

Timbo

So, perhaps the Drake equation...

...can now be further extrapolated along the lines of...

"N = the number of civilizations in our galaxy with which communication might be possible (i.e. which are on our current past light cone);

and

R∗ = the average rate of star formation in our galaxy

fp = the fraction of those stars that have planets

ne = the average number of planets that can potentially support life per star that has planets

fl = the fraction of planets that could support life that actually develop life at some point

fi = the fraction of planets with life that actually go on to develop intelligent life (civilizations)

fc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space

L = the length of time for which such civilizations release detectable signals into space"

So, perhaps we need to add in:

a) = the fraction of dust particles that have an alkaline composition that turn into clumps of material

b) = the fraction of clumps of material that have sufficient water within it

c) = the fraction of water-laden alkaline clumps that just happen to land on a primordial world in an area of space where water is liquid

It truly does begin to look like we do live in a very "Goldilocks" zone, where despite all the likelihood of life NOT forming, on Earth it did.
