I wonder if the NGL people at ETH Zurich have taken into
account that their meteorites were a bit larger before they
encountered Earth's atmosphere. There may have been
significantly greater amounts of noble gas in the original
fragments which also might mean significantly longer travel
time.

But the inside of a meteorite isn't heated by passage through the
atmosphere. It's too quick. I'm sure they would avoid the outer parts
and the fusion crust.

How penetrating are the cosmic rays? If most of them stop in the outer
surface then you'd find higher concentrations of the Noble gas in the
shell of the meteorite that gets burned off.

A relatively few of the components of cosmic rays are extremely
energetic and penetrating... most components are not. I don't
see why the findings are compelling enough to accept shorter
travel times.

That's what I think. Though I readily admit my opinion is only that of
an interested layman.



BTW, nice web site, Hop!

Thank you!

I've seen that "Tunnel" idea before,
long ago... angels and demons together in this manner. I notice
that it's one of the one's for which you don't show a copyright.
Do you know who originated it?

happy days and...
starry starry nights!


M.C. Escher did an angel-devil tessellation.

However my angel-devil tessellation is different. It's one of my
original tiles. The "impossible figure" is Peter Raedschelders' device.
I had the angels and devils entering & exiting the tunnel to draw
attention to the "impossible" part of the city (which I didn't notice
the first few times I looked at it).

Both Peter and I are big fans of Escher.
