for me, one day, life is gonna be found out there....I believe that as fact..
...So, if Opportunity, and future probes fail to find evidence of past or present life, then does that mean that the fℓ = 100% factor of the Drake equation is WRONG?Of course, it could also mean that it is there, but we just didn't find it.Mars, however, may be different enough from Earth that even with surface ice, or surface liquid water it might not have been able to support life. ...
Off topic, but if life originated independently on different planets, then we should expect (on a statistical basis) to find mirror life on at least one of the first handful of planets where we search successfully (i.e. opposite chirality of the biomolecules).
These amino acids "seeds" formed in interstellar space, possibly on asteroids as they careened through space. At the outset, they have equal amounts of left and right-handed amino acids. But as these rocks soar past neutron stars, their light rays trigger the selective destruction of one form of amino acid. The stars emit circularly polarized light--in one direction, its rays are polarized to the right. 180 degrees in the other direction, the star emits left-polarized light.All earthbound meteors catch an excess of one of the two polarized rays. Breslow said that previous experiments confirmed that circularly polarized light selectively destroys one chiral form of amino acids over the other. The end result is a five to ten percent excess of one form,
