But you want to know what is magic about physics?

Forces. Forces are definitely observable. But they are fictitious. A photon (force mediator of the electromagnetic force) is a packet of energy on the electromagnetic field that creates a curvature in the electromagnetic field such that two particles with opposing charges (intrinsic charge) has that field curved together, resulting in what an observer would see as a force.

Gravity? The thing keeping everything on the ground? Not real. Just a result of the spacetime field being curved by the presence of energy in it. In order to escape the curve, you have to exchange energy, which is to be a force.

The fact that you knew exactly what I was talking about enough to pull up the relevant XKCD is impressive good sir/ma'am/(actually I don't know what the non binary term would be there. I know military it's "Sir" regardless).

Also gravitons exist, unless you're looking for them, then they don't. Also they move in curved space time but also don't.

Yes, this is totally real, not just stuff we made up stoned.
