Why bother?

Well, he's already abandoned naturalistic causality by supposing a divine providence of geyser-powered mantle launching--so what if some of the pieces must once have moved (or move now) in a fashion incompatible with naturalistic causality?

It is useful and necessary to debunk abuses of science, but this particular sort of abuse is like a fractal one-trick pony: the closer you look, the more you see the same pattern, endlessly unfolding. Faith supposedly has no need of science, but the supposedly faithful cannot leave it alone, acknowledging its power by seeking to subvert it, thereby creating bad science and worse theology.

I'd say the OP site and author are remarkable not so much because of the near-delusional ignorance, but rather the total ineptitude--not just wacky, stupid wacky.

Our EvC creationists are much smarter ;)

Still, once you've made the big poof, the little poofs are easy.

I'm sure you're correct - the ones launched "backwards" could have all fallen into the sun, for instance. And yup, the rest would pretty much all fall back to earth after an orbit or so, just when ol' Noah was sending out ravens and such. They'd fall hard, too. :D

The problem for Walt is the specific distribution of the asteroids and meteors versus the "global" distribution of his launch mechanism.

To get them into stable orbits that match current positions and speeds and orbits, there can only be a small segment of the earth where a vertical launch could achieve it.

All the rest would be wasted (would not contribute to the observed distribution), and this would be about 99% ...

Rocks launched vertical to the plane of earths orbit, and rocks lauched along the line of the earth/sun, and any others launched in the plane of these two lines, would have the same orbital inertia as the earth, which means that they would all have intersecting orbits with the earth.

Now we could calculate the energy needed to launch the rocks into those stable asteroid orbits and then use that same energy to calculate when the returning perpendicular plane rocks would impact ...

And I'll bet that one could also find some curious orbits that should have asteroids in them if this model were true (retro-grade, eccentric, etc) that do not exist...

If we were really interested in such nonesense.

Seriously though
I have a few questions about what we think really happened.

Apparently, there are 3 main types of asteroid distinguished by composition. Carbonaceous, silicate and metallic types. These types are largely distributed in distinct bands in the asteroid belt. Do we know why that happened?

Is it possible for a small asteroid to accrete into a rock? Doesn't it take a lot of pressure and/or temperature to form rock which would only come after a pretty large size has been reached? Does this mean that all of the small hard rocky asteroids are a result of collisions between much larger bodies?

Frustration Out Of Finding A Meeting Time For Everyone
Pick is a desktop and iOS app that aims to help you find time a good meeting time for a group of people. Instead of blasting an email out to everyone with a bunch of random times in hopes one of those works out, it collects info from all your calendars and determines when everyone has time to get together. The app quietly launched on the App Store a couple of days ago without much fan fare.
