I wrote about recent virtuoso experiments that have measured how long particles take to tunnel through walls. Physicists have obsessed over this question for nearly a century, because it raises a bigger question: What is time, even?
Physicists in the 1960s “were just coming up with crazy ideas of how to measure this time and thought it would never happen,” said Ramón Ramos, a lead author of the new paper. “Now the science has advanced, and we were happy to make this experiment real.”
Quantum tunneling is not as famous as entanglement, but might be even weirder.
