Is it possible that the value of Pi is related to the properties of the spatial dimensions of our universe? Could another universe with different properties see circles differently and arrive at a different value for Pi? After all, Pi is determined based on ratios determined within our own spatial dimensions, and from what I've read, some theories suggest that spatial dimensions may not manifest themselves the same throughout a multiverse. Like all the unexplainable constants I've read about in physics, perhaps Pi has deeper significance than just mathematics. I don't want this thread closed for speculation. So I guess I'm asking whether such a topic has ever been proposed or even makes sense at all.
