*Whew* That’s a relief. Guess we don’t need science, or medicine, astronauts, or telescopes anymore. Think of the money I’ll save on my daughters tuition.

Woo hoo! Left-handers dominate!

Of course you realize; Bill Clinton is a lefty?

You may want to rethink that a bit. :)

Panspermia is a recent scientific hypothesis, but not really new. The term has been around for thousands of years. The cometary hypothesis is not all that new an idea either, but even so, the comets and asteroids etc are all from the same region of the universe, that is, inside the solar system and would probably have some common characteristics with each other and earth whether they collide or not if the nebular hypothesis of planetary origin is at all valid.

Um, politically, and physically. Well, the parts I can see anyway.

I’m also left-handed.

hey, might that explain why half the population votes for the Left?

Not life. Amino acids.

We have seen amino acids come down on meteorites, and form naturally here on earth.

Nothing mysterious about amino acids, but it is interesting that polarizing light in space could preferentially destroys the right handed amino acids rather than the left ones.

But it is a rather weak explanation for the prevalence of left handed amino acids in terrestrial life forms.

“One would have to examine meteors before they become ‘contaminated by the Earth...right now, such a thing is the stuff of science fiction.”

Actually not, see the book “Comet” by Carl Sagan and Ann Druyan. We have sent rockets into the tails of several comets, and have a pretty clear idea of the various chemicals that comets are carrying with them, and can deposit on the earth when they crash.

“If ‘scientists’ are going to push their theories into the realm of faith...well that’s just religion, too.”

These scientists are NOT pushing their theories into the realm of faith. The article is well sprinkled with mays, mights, and by definition, “theory” means they are still exploring the ideas and possible proofs of their statements. Furthermore, near the end the author states that as he does further work on certain aspects of amino acids this may provide additional evidence for the theory. Please do not confuse science and faith. Science seeks answers, faith assumes them.

“inside the solar system”

If you mean within the orbits of the planets, that is not correct. Even if you mean as far away as the ends of the Oort Cloud which extends out about 2 light years and contains about 1 trillion cometary objects, that still may not be correct. See my comment #74 for an interesting source. Some comets may come in from outside the Oort Cloud.

On which day did this happen?

“Science seeks answers, faith assumes them.”

Glib.

And shallow.

You should explore the concept of a philosophical proof sometime. Maybe then you’d be ready to examine the evidence for the existence of God.

That is my definition and is therefore apriori true.

Scientists used to think that metors did not fall from the sky. It was considered folklore, old wives tales etc.

It wasn’t until one fell somewhere in France I think and many of the townspeople were witnesses to this event that this started to change.

The heavenly rock is still on view at the local church in this small town.

Source The History Channel, of course at my age some of the details may be a bit fuzzy.
