Are you referring to dark matter? What kind of invisibility is grounded in physics?
It would require matter (including the inter-particle interactions) involving no absorption or emission of photons.
According to some models, subatomic particles exert action at a distance by exchanging photons.
This is what bothered me about the notion of a “black domain” in the Three Body series
You're wayyy over complicating it, invisibility is just a matter of taking the light that hits you, bending it around you and putting it back in place. We can already do this on a small scale with fixed stationary setups.
Even simpler is just a very accurate and fast camera/display system that records and displays the background onto itself.
