Hi Larry, all -

Yeah, there could be massive bodies out there, but
there aren't. That's what Myles' study shows.

What's sending the comets our way are our solar
system's passings through the plane of our galaxy, the
Milky Way. That's exactly what is shown in the
extinction record, and it confirms the gravitational
model work done by both British and Italian teams.

When will NASA get over the not invented here syndrome
and stop wasting our money looking for Nemesis? Why
don't we spend it on sending some probes out to the
Kuiper belt and Oort cloud, where it might do some
good? Anybody here care to blue sky some designs?

good hunting,
Ed
