Delbert Freeman, what kind of comment is that? I suppose you will throw up some sort of "God" or "Intelligent Design" proposition (I'm not going to call those theories, they don't deserve it), if someone actually cared enough to ask for your opinion. Let me tell you one thing, the Universe is a very big and even stranger place. Shit happens. That includes really improbable shit.

Delbert Freeman, you know how complex life is on this planet? the mathematical formula involved in creating you..the perfect circumstances occurring for life to take the forms it has today?..i would say the probability of the above taking place is much more favorable than life recurring to the exact specifications as on Earth.

Anyway. it's much more believable than the bible.

Are all planets seeded and only a select few allow life to get a toe hold? Where did the seed come from? How did it have amino acids to begin with?
Working our way back, back, back, back to the absolute origin of life itself in any form is all I'm interested in. With so much inorganic in the universe, where did the organic come from!?!?!? It drives me crazy. I guess if I had an answer I'd be famous.

Omigawd! That could led to anorexia nervorsa transportis! And think of the electric bill!

probably safer to do the transport trick on every other meal (like, dinner) and leave breakfast and lunch alone. A whole new market for 'weight-gain-free' food.

Everyone has seen "The Fly" right? I read somewhere that there is another wicked transporter trick and that would be to have that transporter (by accident or by design), reverse all of your moleculars so you were R-isomer based instead of L-isomer. Then you would eat and eat and not gain an oz. Instead, you would starve to death as your body would not use the L-isomer stuff that all of our life used.

Wicked fiction – and I don't even think it was Harlen Ellison. I can remember. And thanks, Mus for beating to the animo acid faux pas.

My comment is a question. What if right hand chirality had been dominant. Would life have been different (possibly more Republican based)? Seriously, any difference?

Interesting theory. Just because it sounds incredible, doesn't mean it's not true. BUT (and it's a big 'But'..), it'll be interesting to see if he can find a method of exprimentally determining if the theory holds up.
Simulations are one thing, actual evidence is another matter entirely.

Yes it is all a bit sketchy. Breslow maybe a professor of chemistry, but his info on the chirality of meteorite seems to be lacking basic review. A couple of examples 1- Murray CM2 – 7racemic (equal) amino's 11-non protein amino's. 2-AH 77306 – racemic. 3-Murchison (Nature230, 105-106 (mar 1971)- racemic, 70 amino's total, only 8 found in terrestial proteins. He's trying to turn a small excess into a major force.

In other words, just the right clump of rock, passed just the right neutron star, at just the right time, at just the right angle, for just the right amount of time, on just the right course, to impact Earth at just the moment it became able to host life. Then within approximately 150,000 years life becomes world wide and genetically varied. "Interesting." No stretch of creditability at all, right?

Wouldn't a meteorite drifting past a neutron star be rotating in some way? Unless it is tidally locked (and unlikely to escape). If so the polarization would change as the meteorite rotates or tumbles. How could it then give rise to left handed amino precursers?

"Amino acids are a type of protein found in all life forms on Earth"

Actually, amino acids are what make up proteins…. proteins are basically just long chains of amino acids which are folded up in specific ways.

Interesting theory… I'd be keen to read more about the proposed mechanism and the reasons for its favouritism of left-handed chirality of amino acids.
