From Paul Vann
Hurrah for the work of Daniel Sudarsky and colleagues in advancing the case for objective collapse theory (OCT) in understanding quantum physics (16 July, p 30). Both the standard (Copenhagen) and the many-worlds interpretations of quantum mechanics are clearly bonkers in their respective requirements. The first demands sentient observers: there are too few of us, and in the beginning there were none. The second generates unreasonably large quantities of “reality”.
There is surely a Nobel prize in a box somewhere, waiting to be opened and awarded to the leading developers of OCT.
