Hi Hilmar,

Ok, I seem to have it backwards. Inverse variation: ... A number expressed using an exponent. The number 5 3 is read five
to the third power or five cubed.

I have recently seen something to the effect that electromagnetic fields and gravity are not the same thing; that electromagnetic field uses inverse variation cubed rather than squared, so I assume electromagnetic field force was much weaker than gravity, but my current understanding is now that gravity is much weaker than electromagnetic fields.

I don't know whether the basic formula for force in both electromagnetic field and gravity are otherwise the same, except for the square used in gravity and the cubed used in electromagnetic field.

I also do not understand what exactly is going on when an object is suspended in midair using superconduction. Is superconduction creating a bubble around the two objects using electromagnetic field, or is the shielding being provided by something else blocking both electromagnetic field force and gravity? Also, how is it that the two object can seem to become connected by invisible strings, so that moving one would cause a corresponding movement in the other?

Superconduction is a hot field in physics, and I hope it yields some secrets as to the fundamental nature of gravity. Who know, a perpetuals propulsion system may be discovered which would make space travel over large distances and time possible. Of course, this would break the engineering principle of conservancy of energy, right?
