Let’s talk

I'm looking for a solid discussion on what I think I concrete evidence for the globe. I don't want people with brains to just comment "they can't respond" or whatever I want flerfs to debate me.

Topic: aurora borealis.

We've recreated it using a spherical magnet and shooting ions and electrons into well tye magnet with nitrogen around it which produces a purplish glow across the magnetic field.

This is something that's recreatable at home (or we'll a student did it, it's not a cheap experiment).

This only works on 2 magnetic poles.

I have looked for a model of magnet with a field that would work on a flat earth, and well there is none. Closest I found was a hypothetical physics problem but it requires a gap between north and south pole, and we'll the southern lights would be off the edge.

I've always been a glober, but I've used this argument many times and it always ends in the person blocking me, condemning me to hell, or calling me a robot.

If there are any actual flerfs here please use science and let's have a civil debate on this topic.
