It is very hard for me to wrap my head around and electron being a point particle. Meaning we know it exists but it has no volume. Can anyone help me with this?
Does light have volume?
Also, so what I am gathering from a vacuum is that there is no such thing as a true vacuum? Which leads to there is no such thing as nothing?
I saw a video of a huge NASA tank that was able to suck out all the air. A feather and a bowling ball were dropped and they did “fall” at the same time. So basically all the air was pumped out so there was know friction to slow down the feather.
But that tank was still filled with a field that was made up of smaller particles than air particles as to not slow down the feather?
