THe real question now is how fast NEUTRONS are produced in large hyper velocity impacts

Neurons E.P.?

How fast are you losing yours?

I believe you probably meant neutrons?

Hi spice -

a whole lot of my neurons were lost in 2005, unfortunately.
typo fixed.

E.P., I would dearly loved to have listened, as well as watched, that video presentation. I hope you can fix the audio someday so it can actually be understood. It's not so much the volume as it is the audio being constantly broken up. Quite impossible to really follow, which is a shame, IMHO.....

I hope I can fix it someday myself.
The audio datalatch broke, andd it took a week to restore the audio to the point it is.

The key points:
1) There were TWO major impact events at the beginning of the Holocene.
2) Their locations can be very roughly estimated by melt water outflows.
3) In as much as the palaeo-climatologists do not agree about the dates for the Younger Dryas Boundary,
it is not useful to describe either of theses impact events in terms of the Younger Dryas Boundary.
4) mt DNA can be used to track crossings to and migrations within the Americas.
5) Fast neutrons are produced in large hyper-velocity impacts.
