Experiments Spell Doom for Decades-Old Explanation of Quantum Weirdness
Physical-collapse theories have long offered a natural solution to the central mystery of the quantum world. But a series of increasingly precise experiments are making them untenable.
Philip Ball

On Twitter, he writes "Personally I think recent experiments have indeed pretty much spelt doom for physical collapse models. They were always a long shot, and I applaud that they are testable - but the writing is on the wall."

It's like supersymmetry, you can always adjust some parameters to bigger/smaller values, or construct a more complicated model, so that the general idea is not ruled out by the last experiments.

Does this mean that when you measure a collapse model, the model itself collapses?
