- Abstract: Despite many successes of quantum electrodynamics (QED), we do not presently have a good understanding of this field of physics. QED has all of the foundational problems that standard non-relativistic quantum mechanics has, and further ones in addition. I discuss some of these problems and some options for what a Bohm-style theory of QED, with an ontology in space and time, could look like. I also point out why the proposal made by Bohm himself in 1952 for QED is not quite convincing. Finally, I outline the kind of Bohm-type theory of QED that I would consider convincing, and report about recent progress toward this kind of theory.

In quantum gravity theory, a state-dependent gravitational potential introduces nonlinearity into the state evolution.
The formalism for understanding the continuous quantum measurement process on the quantum state has been previously discussed using the Schr"odinger picture.
In this work, an equivalent formalism using the Heisenberg picture is developed and applied to the analysis of two optomechanical experiment protocols.

We define the quantumness of a Hamiltonian by the free energy difference between its quantum and classical descriptions.

We consider the Schr"odinger-Newton (SN) theory and the Correlated Worldline (CWL) theory, and show that they can be distinguished from conventional quantum mechanics.
We find that discriminating between the theories will be very difficult until experimental control over low frequency quantum optomechanical systems is pushed further.

It is widely believed that it is very hard, if not impossible, to make Bohmian mechanics compatible with relativistic quantum field theory (QFT)
I explain, in simple terms, that it is not hard at all to construct a Bohmian theory that lacks Lorentz covariance, but makes the same measurable predictions as relativistic QFT.

I criticize the widely-defended view that the quantum measurement problem is an example of underdetermination of theory by evidence.
I argue that there as yet no empirically successful generalization of either theory to interacting quantum field theory.

We will argue that the reason behind the impossibility to reach a meaningful answer to this question is strictly related to the 20th Century Bohrian-positivist re-foundation of physics.
We will also argue that the possibility of understanding QM is at plain sight, given we return to the original framework of physics in which the meaning of understanding has always been clear.
