Like, um, the friction against the ground that the object is moving on. Isaac Newton observed commonplace phenomena then figured out the scientific reasoning behind the phenomena then put it all into words that we now quote as time-tested & true scientific dogma.

Then Einstein comes in and says everything is moving at a constant spacetime velocity, and that friction isn't a real force.

Friction is real, it's the "force" of gravity that is an illusion.

True, like any good physicist, which I am not, I skipped the explanation of physics world. I was trying to be more funny than clever.

Einstein was a bit of a bad boy

Gravity, not friction!
