Dear Benjamin Franklin
I have travelled back in time from 2026 to tell you that we’re still not certain exactly how lighting works.
There are relativistic electrons and gamma rays involved, maybe positrons, and (possibly extragalactic) cosmic rays.
But it’s complicated, and we’re still thrashing out the details.
