Even if the weighing was accurate, that means a force is pulling you down and pushing you up?
That is nearly impossible to consider.
Not at all. You just need to consider the different forces acting upon you.
How can a sphere make anything stick to it if it is spinning? I can't believe it lol.
Can't or won't? If you refuse to believe in gravity, then I'm not sure what to tell you.
No one can explain the mechanism that causes gravity thus you can't explain how a ball would make stuff stick to it.
So what? You don't need to understand the mechanism to see the effect. Do you understand the mechanisms involved in making the CPU in your computer work?
So you're suggesting if the "globe" stopped we would float away?
Umm... No. I don't think that anyone ever said that. If anything, if the "globe" stopped spinning, you would actually weigh slightly more.
I can't see it so, can that actually be proven? If not we probably shouldn't assume.
You don't see electrons flowing in the wiring in your house, let alone the circuitry of you computer, do you? So how can you prove that electricity makes your computer work? You wouldn't want to assume anything, would you?
