How Gravity Can Explain the Collapse of the Wavefunction
Sabine Hossenfelder1
1is looking for a new affiliation.
I present a simple argument for why a fundamental theory that unifies matter and gravity gives rise to what seems to be a collapse of the wavefunction. The resulting model is local, parameter-free and makes testable predictions.
I INTRODUCTION
The measurement problem in quantum physics concerns
the question of why we generically do not observe the out
come of the Schrödinger evolution, but merely one eigenstate
of the measurement observable with a probability that can be
computed from the wavefunction. While we can mathematically describe this process with the reduction (or ‘update’ or
‘collapse’) of the wavefunction, the collapse is then not lo
cal, which is difficult to reconcile with general relativity.

Another way to interpret the statement is that geometry is
a purely relational property that arises entirely from matter.
This, too, is not a new idea; it has been pursued for example in
the context of Causal Fermion Systems [15], Shape Dynamics
[16], or Geometric Unity [17].
Classical gravity already has these features to some extent.
On the most trivial level, we can infer the mass and charge of
a particle from its gravitational field. Furthermore, there are
known links between the solutions of Yang-Mills theory and
those of gravity [18]. A difficulty here is to account for quantum](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:ldv7gbrnwo3n7y5pwdmbrw6v/bafkreiahxpxxjmmt2tbsjcp5pfah53eblk5ybg3iwl56qk5dfik2otsay4@jpeg)
