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."

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

A team of #researchers led by #KyotoUniversity is exploring '#deSitter #space' to invoke a higher dimension to explain #gravity in the expanding #earlyuniverse. They have developed a concrete method to compute #correlationfunctions among #fluctuations on expanding universe by making use of #holography.
