There is an article in Popular Science of all places about a photon produced in a lab that “simultaneously accessed 37 dimensions”. Dimensions are an interesting topic for me philosophically. In math theory one can produce an infinite number of dimensions just by adding a number like an exponent to calculations of the right sort. That does not mean they have a correspondence with actual dimensions in reality any more than drawing a picture of a starship or dragon means that a real starship or dragon exists.
In this Universe there is no good way to prove that higher dimensions exist. Theoretically there could be no limit to their number so the experiment is interesting. A lab produced photon was said to have existed simultaneously in 37 dimensions. ” The Greenberger–Horne–Zeilinger (GHZ) paradox describes how quantum theory cannot be described by local realistic descriptions.” This is kinda fun to consider.

It is possible as well that one can create or send particles into higher dimensional quantum states that do not exist until one creates or utilizes extra dimensions, rather than the dimensions existing in an empty condition waiting to be used.
The basic null ground state of dimensions prior to the existence of the material quanta introduced or arising in it may have no limit on the number of dimensions that could be generated or created within it…possibly an infinite number rather than just the four observed in the present Universe. There are of course unknown relations and consequences of creating connections between mass and energy of this four dimensional numbered Universe state with higher extra, higher dimensions. What those consequences are is not known presently. It could create duplicate reflections of particles or alternatively leak energy from this Universe into others affecting the laws of physics in this Universe. It is all fascinating to consider.
Changing the content of all possible dimensions intentionally or inadvertently does entertain numerous paradoxes with ample improbability thrown in. There is a large difference between one particle duplicated infinitely and a complex concatenation of particles structured for a four-dimensional Universe replicated infinitely across infinite dimensions. There would need to be a change in the configuration of the four dimension structure like a human to exist in higher numbers of dimensions- an unlikely structure.
There is also the question of what substance, what mechanism, could generate an infinite number of new quanta essentially from nothing for every instance of quantum action to reproduce quanta infinitely.
It is all fascinating to consider.
