Black holes are often described as cosmic traps from which nothing can escape, yet modern physics says they are not perfectly black. At their edges, quantum effects make them glow with a faint thermal ...

Physicists have long known how lightning ends, in a blinding discharge that can heat air hotter than the surface of the Sun, but the precise trigger that starts a bolt inside a cloud has remained ...

An obscure quantum-mechanical phenomenon involving a warm glow visible only to accelerated observers, long thought almost impossible to detect, should be measurable in the laboratory after all. So say ...
