ELI5: Why does chewing mint gum make everything you drink feel like liquid nitrogen?

tgpineapple: Your mouth has receptors called TRPM8 that usually respond when there is low temperature in your mouth which tells your body “Hey its cold!”. It does this by opening an ion channel and letting charged molecules flow through which creates an electric signal that goes your brain.
Menthol or mint oil in mint gum can bind to these receptors, causing them to activate. This tells your brain “Hey its cold!” in your mouth when it really isn’t.
A similar mechanism exists for chillies, which is why they’re “Hot”.

I read a comment that piqued my interest and have been trying to find some deeper info on the subject. The comment basically said that as the universe expands, something on the Planck level is dividing like cells, producing more space. I’m not asking for an explanation of that concept, but rather wondering precisely what is happening on that scale when space expands.
