ALL around us are tiny doors that lead to the rest of the Universe. Predicted by Einstein’s equations, these quantum wormholes offer a faster-than-light short cut to the rest of the cosmos—at least in principle. Now physicists believe they could open these doors wide enough to allow someone to travel through.
