Existence, in the most general sense, is logical consistency. In this sense, the universe exists because it is identical to itself. And since it is impossible for it not to be identical to itself, it is impossible for it not to exist.

I am wondering if it is possible for there to be a new type of particles that interact with known physical particles so weakly that they elude our observation, but which may influence certain physical systems in a significant way by amplifying their weak interaction via resonance. Specifically, I have in mind physical systems like a brain, where the putative weak force might induce significant resonance on the scale of neurons or neuronal networks. This would result in measurable changes in fMRI or EEG but due to the limited level of detail of our measurements of complicated brain processes it might be difficult to tell whether these changes are entirely caused by known physical forces. Would it be possible for such weakly interacting particles to induce measurable changes in brain activity via resonance?

Laws of physics can be thought of as features/properties of the universe. As such, they are objects that don't exist in any particular place or time but they are "instantiated" (exemplified) in the behavior of concrete objects that exist in spacetime. As another example of a feature/property, consider the triangle: the triangle (as a general object) doesn't exist in any particular place or time but it is instantiated/exemplified in concrete triangles that exist in spacetime. The instantiation relation between a property and its particular instance seems ineffable (unanalyzable) and simultaneously obvious. In that respect I think it is similar to the composition relation between a collection and its part. The nature of properties and the way in which they exist has haunted philosophers since the time of Plato.
