NOT including the prediction capabilities of the particular math equations of GR or SR.
In particular, hard evidence such as, or close to; here's an electron, because we measured it directly, or saw it in an electron microscope.
Or here's a cell under a microscope.
Or this is a brain scan/MRI etc of persons on LSD-25, these regions of the brain are active during lsd.
Or here's x-chemical in this plant, because we analysed it in a GS-MS.
Or this star emits x-form of electromagnetism.
etc..
On this basis,
*Is there any basically direct measurements/hard evidence of the curvature of spacetime?
*Is there any basically direct measurements/hard evidence of the lack of mass in a proton?
And if so, what is it?
