Gravity’s Most Extreme Effects Can Now Be Tested In A Laboratory (Synopsis) [Starts With A Bang]
“It’s not the job of the theorist to defend his model at all costs!” – Joel Primack
One of the more puzzling phenomena in our quantum Universe is that of entanglement: two particles remain in mutually indeterminate states until one is measured, and then the other — even if it’s across the Universe — is immediately known.

In theory, this should be true even if one member of the pair falls into a black hole, although it’s impossible to measure that. However, we can (and have) measured that for the laboratory analogue of black holes, known as “dumb holes,” and the entanglement survives!
