A new study suggests that a surprising number of universes, even those with laws of physics different from those in our universe, can still support stars.

God doesn’t play dice, Einstein said in his critique of quantum theory. But any alternative theory to quantum mechanics would require certain quantum events to influence each other 10,000 times faster than the speed of light, physicists have shown.

Simulating new materials could help in building them — but only quantum simulators could fully model reality. A team reports a first step in realizing quantum simulation.

An essay by Tom Siegfried, SN's Editor in Chief, explores how signals from space to Earth could establish the reality of Einstein's worst fear.

The mathematics of soapy water yields some clues to the origin of the genetic code.
