I received hundred of downvotes just asking questions here (like "Why we have right hand rule for current? What must be changed in properties of Nature to make it left hand rule?"). It's sad that I need to use throwaway accounts to talk about physics.

Try not to be discouraged, it's okay to talk about physics. But try to use the right language for it - mathematics. In online forums, physical ideas or questions are often described in words, which is subject to so much imagination that it can be considered philosophy, but not physics. It's almost pointless to talk without mathematical support. Words are words and have no special meaning. In the example above: A better question would be: Why is classical electrodynamics described by Maxwell's equations? Is there a more fundamental theory behind it? Reason: The 'right-hand rule' is not a rule, not a theorem. It can be derived.
So what need to be changed in properties of Nature to switch EM with Right Hand Rule into EM with Left Hand Rule? Can you explain this using a formula?

Where we can expect to see EM with LHR? Can we see it in our Laniakea? Or at opposite side of Shapley Attractor - Dipole Repeller? Or at perpendicular one? Do we have void between RHR and LHR? Can we cross it?

What is nature of EM? Is it because of nonlinear trajectory of motion of our galaxy from Dipole Repeller to Shapley Attractor? Or it because of non-linear motion of our galaxy within Laniakea? Or something else?

I can't take you seriously anymore.
You are not alone - nobody can. I'm struggling to find just anybody to talk about these problems.

How photons are formed? IMHO, FTL speed is required to form a photon.

How photons are consumed? Can we make a macro model for this?

Can we cool/condensate/warm up vacuum? How this will affect speed of light?

What will see if we will zoom in to zoom level below Planck scale?

How long photon can travel? 100B years? 100T years? What will happen at EOL? Where lost energy is going?
