All they did with these experiments, Alex, was "simulate" the craters...then they went and verified what formed them. It wasn't massive electrical discharges
There's no evidence, anywhere, showing that craters are formed from massive electrical discharges, no matter what your lab experiments say.
What is your real life evidence....apart from a few pits burnt into a metal or glass surface by a plasma arc torch
Go to Meteor Crater, in Arizona, and you dig me up the irrefutable evidence for a plasma arc discharge, and I'll change my mind. How's that.
You impress me with your geological knowledge and understanding of impact crater physics and I'll sit here and listen to what you have to say.
Write up a paper and have it published.
