Thank you Laura, Andromeda and the whole team for the session and for sharing it with us.
While reading about Pierre my smile grew bigger and bigger as I read on, what a blessing to chat with him!
Indeed, I feel the same and there is so much to reflect on this!
About the "great noise surrounding Earth" Pierre talked about, hereafter
The scary sound of Earth’s magnetic field (the complete article was shared
in the "Sol (Sun) and its phenomena" thread by @Ca.):
It's a mixture of avalanche noise, mud and rock flows, tinkling bowls, threatening storms, rusty gears turning, a radio that's hard to pick up, the advance of a glacier in fast motion, coins being shuffled, and many other things...
Short version of the scary (really!) sound on X:
A longer version (5mn) can be found in the article above, but the link worked just fine with Media tool:
IF that is partly what Pierre is hearing, I understand why he used the term "great noise"!
Edit: Forgot to add my impressions hearing at The scary sound of Earth’s magnetic field.
