The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness.
In the latest campaign to reconcile Einstein’s theory of gravity with quantum mechanics, many physicists are studying how a higher dimensional space that includes gravity arises like a hologram from a lower dimensional particle theory.
A controversial new paper argues that universes with dark energy profiles like ours do not exist in the “landscape” of universes allowed by string theory.
Gravitational waves have opened up new ways to test the properties of black holes — and Einstein’s theory of gravity along with them.
The renowned British physicist, who died at 76, left behind a riddle that could eventually lead his successors to the theory of quantum gravity.
A recently proposed experiment would confirm that gravity is a quantum force.
The theoretical physicist Joe Polchinski, who died February 2, left a tremendous professional and personal legacy, says a friend and collaborator.
