There is an epistemic and metaphysical difference of opinion about reality and the extent to which mind interprets and shapes its perception to conform to survival requisites. Instead of perceiving reality mind perceive a virtual box useful to it that is allowed by an unobserved reality. The topic is rather spacy and has numerous varieties.
Apparently Einstein too may have been something of an idealist for a while. Godel wrote about that in 1949. “Remark about the relationship between Relativity theorz and Idealistic Philosophy”.
Some believe that even gravity doesn’t exist in a heterodox relation with mind; that is, objectively?(is that even a valid term in the virtual box of perception paradigm)? They regard mind as shaping percepts that don’t actually reflect reality. Donald Hoffman is a recent developer of the theory.
If experience is a phenomenon of quantum Higgs field entanglements that ‘reality’ may be what is regardless of how it’s supported?
I need to read Godel’s paper on idealism and relativity. If God is hosting the show there is no way to discover how the metaphysics work.
To find out what the field configuration supporting the virtual box and gravity is will be very challenging for physicists. Perhaps researchers will go with what is possible starting from the evident.
I haven’t read Hoffman yet. I will get to that. In that paradigm one could theoretically turn off gravity if the perception/metavirtual box relation was understood.

Maybe regard space time as a contiguous field that stretches like silly putty from a point to a vast pancake. The motion is space-time. Everything that happens in it are variegated particles of the field cycling through relationship protocols.
Lately there has been something of a return to idealism with mind interpreting reality in its own way for survival purposes. So in effect people experience apparent reality as if they were in a virtual box on a computer without actually experiencing the real reality.
That leaves a lot of room for fiction accounts of mechanics
