Actually, I don’t think they do. But the amount of space it takes up is spherical because it moves at high speed. It’s actually a wave. If that doesn’t make sense to you, it’s because it shouldn’t. Any attempt to relate the nature of subatomic particles is pure metaphor, and I’d be lying if I told you I understood it.
Take any point on a sphere, and roll the sphere along a path.
The trace of the point will make a wave on a chart.
Now, that has absolutely nothing to do this, of course.
That remark alone proves you are more intelligent than most of us. And a darn sight more honest.
