Quantum fluctuations and space

[Schreiberdk]

Hi PF

Can quantum fluctuations create space? And if so, could quantum fluctuations have created the universe and therefore spacetime we live in?

I believe some form of space time vacuum must already exist to liberate a quantum fluctuation.

This subject in one form or another is still open to debate today. One of the original papers that started it was: "Is the Universe a Vacuum Fluctuation?" by Edward P Tyron.

The physics of generating a universe from literally nothing according to quantum mechanics is open to interpretation.

In order to answer this question one needs a physically fully developed and mathematically sound theory of quantum gravity (or "quantized geometry") including coupling to all other quantum fields. There are various research programs addressing these questions but none is in a stage which makes it possible to present a serious answer.
