While that is true, it's obvious you don't understand how the orbital trajectory of the asteroid belt works. Even if it was 100% mapped, it changes every year. The same is true of the Ort cloud.
Holy shit, that's stupid. Beale thinks we just map positions, and don't map orbits.
If 100% of the objects were mapped, we'd know 100% if earth was going to be a target of any impact in the next few hundred years. We couldn't extend predictions out to infinity, of course, as to some extent the solar system is a type of chaotic system, and very small perturbations could make for much bigger changes way down the line. A comet burps gas in one direction, it might change the orbit, swing it nearer another body, and change the orbit more.
Where do folks get their information? How is it their education and understanding of the solar system and the forces that affect the Earth is so dismal?
I guess that is why it is so easy to sell them this AGW bill of goods, eh?
That sort of belligerent ignorance is typical of those afflicted with Dunning-Kruger Syndrome. Most deniers are simply too goddamned stupid to understand how goddamned stupid they are.
I never said I thought we just mapped positions instead of orbits. You shouldn't project words and ideas onto me. Straw man much?
Intelligent folks know that there are multiple shifting gravitational forces in both the Oort cloud and the asteroid belt that are constantly upsetting orbits and pushing shit out. They could have everything mapped, 100%, and next year, bam, a collision in the asteroid field because of a shift or an instability, and whamo, one starts heading right for us.

Likewise, people that study the forces that affect the entire solar system and the galaxy know that the weather that takes place on Earth doesn't happen in a vacuum. We might be drifting in space, and they may teach you in school that it's a vacuum, but there is a lot of shit in that vacuum.
I know, I know, the MSM and all the stuff you read in those journals meant for consumption by the masses doesn't like to talk about it, but eh. . . what are you going to do?
