Our understanding of the universe may not be expanding as much as the universe itself. In some cases, our theories about cosmic inflation may feel as if they are deflating into a black hole. Black ...

The space-time filling the region inside the bottle—a continuum that bends and undulates, producing the force called gravity—exactly maps to a network of quantum particles living on the bottle’s rigid ...

Physicists have devised a holographic model of “de Sitter space,” the term for a universe like ours, that could give us new clues about the origin of space and time. The fabric of space and time is ...

Quantum field theory in de Sitter space investigates the behaviour of quantum fields on a background with constant positive curvature, embodying an exponentially expanding universe. De Sitter space ...

May 22 (UPI) --A new computer model predicts the possibility of naked singularities in four-dimensional space, challenging Einstein's general theory of relativity. The theory of relativity describes ...
