Marrakech Biennial 4 “Higher Atlas”
Curated by Nadim Samman and Carson Chan.
Theatre Royale, Marrakech.
The Installation has been realized for the Marrakech Biennial, it is composed by six black platforms connected by a continuous flow of white florescent light, arranged on a total surface of 25 m², in order to keep on fluctuations, five luminescent sponges and one polished aluminum egg.
in the action has the same symmetries as it does to provide the Einstein–Hilbert action. But the form of
is not unique and can be posed by the different forms:
The Plebanski action can be constrained to produce the BF model which is a theory of no local degrees of freedom. John W. Barrett and Louis Crane modeled the analogous constraint on the summation over spin foam.
which formally satisfies the Einstein’s field equation of general relativity. However, if analysed with the tools of loop quantum gravity the Barrett–Crane model gives an incorrect long-distance limit , and so the model is not identical to loop quantum gravity.
