Part 10/11:
This "universe as a spinning top" hypothesis is still in preliminary stages but draws on the ancient philosophical notion that "panta rhei"—everything flows and moves. If confirmed, it could revolutionize our understanding of cosmology, implying that cosmic parameters and expansion rates are influenced by properties we have yet to grasp fully.
The Road Ahead: A Cosmic Puzzle
Resolving the Hubble Tension is critical because it affects our estimates of the universe's age, size, and future trajectory. If the lower CMB-based value holds, the universe is roughly 13.8 billion years old and will expand forever at a steady rate. If the higher, local measurements are correct, the universe might be younger, expanding faster, and potentially presenting new, unknown physics.
