Prof. Nima Khosravi of Shahid Beheshti Uni. and IPM has won the Buchalter Cosmology Prize for 2016.

The Buchalter
Cosmology Prize is an annual prize that seeks to stimulate
ground-breaking theoretical, observational, or experimental work in
cosmology that has the potential to produce a breakthrough advance
in our understanding.” In 2016, the $10,000 First Prize was awarded
to Dr. Nima Khosravi of Shahid Beheshti University for his work
entitled “Ensemble Average Theory of Gravity” recognized by the
judging panel as “a novel proposal that suggests new ways to
approach outstanding problems in gravitational physics, weighting
the contribution of different self-consistent theories of gravity to
show that different theories may prevail in different environments
in the Universe.” In his work, Arxiv Link, Nima puts forward the idea that all theoretically consistent models of gravity should play a role in the finally observed gravity force. This idea basically says one should take ensemble average of all the consistent models of gravity. Nima could show that in an example of this idea one can get a modified gravity model which behaves same as Einstein-Hilbert (EH) case for very large curvatures. But the smoking gun will be very low-curvature regime where gravity is less than EH and may explain dark energy. There is also an intermediate-curvature regime where gravity is larger than EH’s prediction which can affect the structure formation of dark matter. |
