Electromagnetic fields. Be forewarned, this involves science...

I like science a lot. But I don't believe it just because someone says it is science. In this case, the first several minutes are history, not science. At nearly an hour long, I'll watch later

@pekri

How do you get to your conclusion based on the words and context I wrote?
The first part was the history of some science., Not science. And I don’t have time to watch it now.
