A new ‘Einstein’ equation suggests wormholes hold key to quantum gravity

ER=EPR summarizes new clues to understanding entanglement and spacetime

Wormholes, tunnels through the fabric of spacetime that connect widely separated locations, are predicted by Einstein’s general theory of relativity. Some physicists think that wormholes could connect black holes in space, possibly providing a clue to the mysteries of quantum entanglement and how to merge general relativity with quantum mechanics.
