The Perfect Harmony in the Sky

 The Perfect Harmony in the Sky

As is commonly known, celestial bodies are not perfectly spherical; they take various geoid-like shapes. This occurs for several reasons, such as the irregular magnetic pull generated by their inner cores. So, which celestial body do you think exhibits the most spherical shape, and is "perfect sphericity" even possible?

Let me begin by answering the second question: No. Perfect sphericity is theoretically impossible, even for the most massive stars. The closest approximation we have observed is the star Vega, located on the outer-middle edge of the Andromeda galaxy. You might wonder why Vega comes so close to this ideal form. Being significantly distant from the black hole at the galactic center, it lacks any prominent external magnetic force acting upon it. Its core accounts for the vast majority of the star's cumulative weight, allowing the core to establish its own sphericity first and then uniformly pull the surface toward itself.

Celestial bodies maintain their integrity according to the following gravitational equation:

g= G*MU/R*R,

In this formula, M represents the mass of the star, r is the distance from the center to the surface, and G is the universal gravitational constant, which is determined through observation rather than a fixed derivation.

However, the center of mass and the center of gravity of stars do not coincide at the exact same point, which prevents them from appearing perfectly spherical. The fundamental reason for this is that the expansion process following the Big Bang was not entirely homogeneous. From this, we can conclude that the universe itself does not possess a perfectly spherical shape. To put it simply, the distance between the "North-South" poles of the universe differs from the distance between its "East-West" points. In short, the universe does not have a flawless geometry.

Consequently, since our universe is not "perfect," it can be inferred that it is not unique. This makes it possible to concretize the theory of Parallel Universes, transitioning it from a mere hypothesis into a scientific data point. So, how can one travel between them? Wormholes are not just a theory; they are the exit routes from this universe. How so? Well, that is a story for another time.
