Introduction Modern cosmology relies heavily on two unknown components: dark matter , dark energy . They explain observations - but we still don’t know what they are. Drogidi Theory proposes a completely different approach: Dark matter and dark energy are not particles or fields. They are geometric effects that arise when multiple spacetime “sheets” interact. This idea leads to a unified explanation of: flat galaxy rotation curves, gravitational lensing, cosmic acceleration, CMB uniformity, and even local Big Bang events. All of this without introducing new particles or inflation. The Core Idea Drogidi Theory starts with a simple but powerful concept: The Universe is not a single spacetime. It is a set of multiple geometric sheets (manifolds). Each sheet: has its own metric, its own curvature, its own evolution. These sheets interact through mapping fields - smooth geometric maps that “project” the curvature of one sheet onto another.…
