The case of Quantum Gravity with Spontaneous Collapse of the Wave Function
Abstract
When about half a century ago the concept of universal spontaneous collapse of the wave function was conceived it was an attempt to alter standard nonrelativistic quantum physics. As such, it was largely ignored by relativistic field theory and quantum gravity communities. A central motivation of spontaneous collapse community has been to replace the standard collapsebymeasurement that annoyed many. With few exceptions, it did not annoy the field theory and quantum gravity communities. Concept of certain generalrelativityrelated universal irreversibility in quantum field theory had been initiated very long ago by Wheeler, Hawking and a few others independently from the concept of spontaneous collapse. Lately the two concepts started to converge and support each other.
