OKThe Universe has two fundamental aspects to it , life and physical things , from the micro to the macro .
OKThe physical , Quasars , Galaxies , stars , planets etc are the foundation on which life takes hold .
Yes, planets are reservoirs of chemistry and chemical reactions to provide those "footings". Not all planets qualify for the term Cinderella planet.Life needs a footing so speak in which it take hold and grow
But Earth has undergone some 2 trillion, quadrillion, quadrillion, quadrillion (2 x 10 ^54) chemical reactions during its lifetime. Can't ever match that in a lab.......
No wonder we have the variety of life in all species, everywhere.
We got Air, Water, Minerals aplenty
Start the clip at 25:10 to avoid lenghty introduction.
Actually we have a pretty good idea, it's just that we are speaking about nano-chemistry and polymerization and at that level experiments become complicated and difficult to monitor. Watch the Hazen lecture. It touches on a lot of things.Here is the thing though , so far we don't know where DNA comes from . It is a conundrum .
One interesting point is that life on earth only uses some 500 different biomolecules. Which is a very small number of fundamental types of molecules compared to the number of cells which run into the millions.
