"Theoretical physicists have long been trying to devise a complete theory of gravity that would also account for quantum mechanics phenomena, as existing models do not. Such a theory could collectively explain the many intricate physical and cosmological phenomena observed over the past decades.

Researchers recently carried out a theoretical study exploring the possibility that holography, an approach to quantum gravity that includes some features of conventional holograms, could be used to describe quantum mechanical phenomena."

Johannes Hagemann, DESY (formerly UGö): Enabling online phase retrieval for in-situ and operando

No absorption for small objects, that makes us sad
but, phase shift for the rescue!

“meso objects” of sizes 500 nm to 1 mm; with complex internal structures that are to be analysed

phase and absorption mixed, “troubling” regime:

Imaging method: X-ray near-field , with the object in the diverging beam and free-space propagation
