Seriously though, continuing this debate does increase the risk that Glenn might be seduced by "crackpot web sites", or Don by his "beautiful neighbor".

I don't know, it may be keeping Don out of trouble. His wife did find him at his computer. If not for the lure of the debate.... laugh.gif

Question: Blueberry - hailstone or concretion?

Experiment: Close study of a blueberrry.


Unless you're pulling my leg, I don't see how that works. Unless you're including meteoritic infall as "hail" . . .

But if you are serious, please explain; this is very compact indeed! :-)

Boy, are we having fun!

Seriously, though, and in the spirit of Centsworth's belief that we should give the basal surge theory the benefit of the doubt, I would like to expand on ngunn's mention of hailstones.

The blueberries, to me, are clearly concretions, and not projectiles or ejecta. (I live not far from a part of Louisiana [Washington Parish] where hematitic concretions in the soil are common, and, except for the color, they are very like the blueberries.)

However, hailstones -- which also resemble the blueberries -- are a kind of atmospheric concretion, and perhaps one could argue that blueberries coalesce in the cloud created by a meteor strike and are scattered as part of the deposition of the freshly created layer.

Again, this seems rather far fetched to me, and I mention it only by way of going the extra mile to accomodate Dr. Burt. Not to mention the following related points, on which I would be grateful for some corroboration:

1) Does not the formation of hailstones require a strong updraft, to hold the hailstones aloft, or at least slow their descent, as they form layer by layer? And how could equivalent conditions obtain after a meteor strike? In the strong updraft from the explosion? Or in the parabolic arc of the ejected material, in which there would be a kind of equivalent weightlessness? And how do either of these scenarios square with the idea of basal surge, which, I assume, means "ground hugging"?

2) Did not a RAT cross section through several blueberry-filled layers specifically show that the layers under the blueberries were NOT dimpled as if from impact?

Doug, sorry if I am covering old ground, but I am doing so only in response to new comments that have been made here, and, I hope, in a way that sheds new light on things . . .

Sorry, but yes, you are covering old ground, so far (and no one would know better than me). New ground would be most welcome. Feel free to PM me if anything particularly bothers you. And Centsworth and Shaka, most of my female neighbors were probably beautiful at least 50 or 60 years ago..., but I do appreciate UMSF watching out for my virtue. laugh.gif

Please don't. Doug was serious. Discussion closed.

If Occam had heard my theory, things would be very different now.
