THE WARPED SIDE OF THE UNIVERSE: NUMERICAL RELATIVITY, GRAVITATIONAL WAVES AND MACROSCOPIC QUANTUM MECHANICS

There is a "Warped side" to our universe, consisting of objects and phenomena that are made solely or largely from warped spacetime. Examples are black holes, singularities (inside black holes and in the big bang), and cosmic strings. Numerical-relativity simulations are revolutionizing our understanding of what COULD exist on our universe's Warped Side; and gravitational-wave observations (LIGO, VIRGO, LISA, ...) will reveal what phenomena actually DO exist on the Warped Side, and how they behave.To detect the gravitational waves and extract their information, in ...

SECRET LIFE OF SPACETIME

Combining the principles of general relativity and quantum theory still remains as elusive as ever. Recent work, that concentrated on the points of conflict and contact between quantum theory and general relativity, suggests a new perspective on gravity. It appears that the field equations of gravity in a wide class of theories - including, but not limited to, standard Einstein's theory - can be given a purely thermodynamic interpretation. In this approach gravity appears as an emergent phenomenon, like e.g., gas or fluid dynamics. I ...
