The History of Waves and Oscillations

I was going to say there's not like super large spaces in the universe that are like in that state of vacuum. But really, we don't actually know. This is all speculation at this point. I think there is that electrons are massless. Oh, that's well, that's something I learned today as well. That's pretty interesting. And they have real properties. As I was reading it, like my level of comprehension in that like subject is beyond me.
