Certain molecules do exist in two forms which are symmetrical mirror images of each other: they are known as chiral molecules. On Earth, the chiral molecules of life, especially amino acids and sugars, exist in only one form, either left-handed or right-handed. Why is it that life has initially chosen one form over the other? A consortium bringing together several French teams led by Louis d'Hendecourt, CNRS senior researcher at the Institut d'astrophysique spatiale (Université Paris-Sud 11 / CNRS), has for the first time obtained an excess of left-handed molecules (and then an excess of right-handedones) under conditions that reproduce those found in interstellar space. This result therefore supports the hypothesis that the asymmetry of biological molecules on Earth has a cosmic origin. The researchers also suggest that the solar nebula formed in a region of massive stars...
Chiral molecules are molecules that can exist in two forms (enantiomers) which are symmetrical mirror images of each other, one left-handed and the other right-handed. For instance, our hands are chiral since they come in two forms, the left hand and the right hand, that are symmetrical with their mirror image but not super imposable on it. Biological molecules are mostly chiral, with some forms being favored over others. For instance, the amino acids that make up proteins only exist in one of their two enantiomeric forms, the left-handed (L) form. On the other hand, the sugars present in the DNA of living organisms are solely right-handed (D). This property that organic molecules have of existing in living organisms in only one of their two structural forms is called homochirality.

This is sooooo sinister.
To me, the preponderance of ever sillier theories illustrates the deperation and frustration experienced by Darwinists trying to make sense of the origins of life. Bob
IIRC, there is no known physical, chemical, or electrical process that explains much of the behavior of the molecules in a living cell.
These things are either self-aware and acting on purpose, which is preposterous, or something is directing them.
Life is not a natural process.
Life is a supernatural process.
The natural processes take over when you die.
Turtles all the way down. The most unsatisfactory of explanation-substitutes.
But, once you find out that one of the processes has to have an outer space origin I'd think your belief in that nonsense would weaken, and here the guy is faced with TWO processes that have to have an outer space origin and he's still praying at the same old temple.
Any sort of a lire from space theory is basically just kicking the can down the road a block or two; the laws of mathematics work just as well there as they do here and evolution is just as impossible there as it is here.
OK.
Where did the molecules originate from on the planets/asteroids/space dust that that brought them to earth?
This answers nothing.
assuming there was a difference in L vs R enantiomers in space,
what would happen once these molecules reproduced (how is that
done anyway?) on earth?Since earth conditions produce 50/50 racemic
mixtures they would reproduce as racemic mixtures,
and eventually any excess L vs R(derived from space) would
be degraded off...and we would end up with a 50/50 racemic m¡×.
As mentioned, how do these aminoacids reproduce??? I think they
are synthesized denovo from non biological entities...so back
to square one....
A good test of the hypothesis would be to get some of
that meteorite material which has excess L vs R, and
put it in a bath, with raw materials, lightning, electricity,
heat, etc...and find out the ratios of L vs R which
eventually develops....
from the original fourth planet, before it got out of line, er , orbit, and the lord pitched a planet sized fast ball into it.
Uhh....Does anybody know if the fingerprints on one hand are mirror images of the fingerprints on the other hand? (Can’t remember the terminology—it’s been 45 years or so.)
The naturalists are insistent upon keeeping up the facade that they are ever closer to uncovering the mysteries of life. Experiments aren’t going well on this planet, but you just know that conditions in some other world were just right. And ofcourse intelligent beings transported life to earth! Aha! Bob
You sperm of Darwin! You...
Oh, sorry, I got a little carried away there.
Proceed.
It’s even worse — the research was published in 2010 C.E.!
Not exact, no. There’s a general resemblance. Usually.
Indeed. And the atheists’ pathetic inability to deal with the Universe’s fine tuning for life causes the brighter of these filth to reach for their “infinite number of universes” theory....it is quite sad actually.
