One problem I noticed right off the bat with your critique is that scientific discovery can proceed in the opposite direction as you assert.

OP has laid out a hypothesis based on an actual physical/mechanics phenomenon. Just because he hasn't done the next step in testing the hypothesis mathematically doesn't mean it's not useful for discussion.

Hypothesis first: Check Mathematical proof: step 2 Experimental validation: step 3

Responses like yours, with snide dismissive comments like this are what demotivate people to push on to the next steps.

Crackpot wall of text posts are always a great source of entertainment!

A perfectly round wheel won't roll frictionless/forever - unless you find an infinitely stiff surface to roll on, that is. A single point/line of contact will create infinite pressure, the wheel will sink in until the surface can support the weight. Along the area of contact we now have forces of adhesion, and moving the depression to roll forward will take up energy as well.

Your entire thing about a sphere assumes objects can't deform at all.

Even if your assumptions about a perfect sphere are true, you could pick it up because your hands and fingers deform slightly and will match the surface.

Wow. Douglas Adams was right, then. His frictionless spacecraft was like impossible to see properly and had no color, just black. And you couldn’t touch it, either. Your hands just kept slipping away off it.
