The Curious Case of Missing Asteroids
NASA Solar System Exploration ^ | February 25, 2009 | Lori Stiles

Posted on 03/03/2009 7:31:32 PM PST by SunkenCiv

University of Arizona scientists have uncovered a curious case of missing asteroids. The main asteroid belt is a zone containing millions of rocky objects between the orbits of Mars and Jupiter. The scientists find that there ought to be more asteroids there than researchers observe. The missing asteroids may be evidence of an event that took place about 4 billion years ago, when the solar system's giant planets migrated to their present locations. UA planetary sciences graduate student David A. Minton and UA planetary sciences professor Renu Malhotra say missing asteroids is an important piece of evidence to support an idea that the early solar system underwent a violent episode of giant planet migration that might possibly be responsible for a heavy asteroidal bombardment of the inner planets. The scientists are reporting on their research in an article, "A record of planet migration in the Main Asteroid Belt," in the Feb. 26 issue of Nature.

Something one should not miss. I used to get them when I was younger but not in decades.

No problem. To my perception, chance is sort of immaterial, granted that the Earth has been hit countless times in the past. We’ve collectively won that lottery again and again over time, and will again in the future. It’s just a matter of when, and how large of a jackpot. That’s where odds enter into the picture, I suppose.

We saw a big collision on Jupiter a couple years ago. These things don't just happen every few months or so. Wadya want, egg in yer beer?

Who would claim that buying four tickets out of a million would leave you with a one in four chance of winning?

It would leave you with a (4 / 1,000,000) change of winning, which is exactly four times more than one ticket (1 / 1,000,000).

Wasn't that the Comet Levy Shoemaker ?? i.e string of pearls...
Forgive me if the past information hasn't taken hold in my brain.. but ? what is the difference between a Asteroid and a Comet ?

Unless your talking astronomical and geologic scales. The difference in those odds in that range could mean the difference between the developement of lower and higher organisms on an otherwise habitable world...

The only way to handle the missing asteroid problem is to immediately adopt socialism on all planets. If this doesn’t work, more extreme measures may be required.

Don't look at me, I didn't take 'em.

My mistake was making the assumption that a four-fold increase was the same as a one in four chance. I see that was incorrect.

I was merely trying to use large numbers as examples since they are representative of the large numbers applied to astronomy. Yet my example is still insignificant. Our galaxy is 100,000 light years across, and yet that is still a speck in the universe.

It's mind numbing wonderful, awe-inspiring.

Not Nibiru (although that would be an amusing name for any newly-discovered outer planets, should that happen), but something created the “Kuiper cliff”, just as something (else) produced these “missing asteroids”. In the latter case, the asteroids may be missing because they’re not really missing at all — this could point to the non-reality of the commonly accepted models of solar system origin.

so they disappeared at the time of the “great bombardment”? Something must have perturbed their orbits.
