So, what are you willing to bet?

It took me a while but I found a link to Birkeland's theories on comets. https://www.plasma-universe.com/Comets:_Kristian_Birkeland%27s_theory

This is all in his book 'The Norwegian Aurora Polaris Expedition, 1902-1903'

By the way, I did see your fakebook post referring to me. It left me feeling sorry for you.

Peace
