Regarding this law though: what about a magnetically suspended top, spinning in a vacuum? Are there still forces acting upon it to slow it down?
= = =
Magnetic forces are suspending it.
And probably will result in slowing it.
And if you can really get a vacuum.
Gravity is EVERWHERE.
Even in the depths of ‘intergalactic space’ there is gravity.
In order to eliminate gravity you would have to leave this Universe. But even then you would take some gravity with you.
If there was a universe that had only two hydrogen atoms in it, separated by billions of light years, there would still be ‘gravity’.........................
