Hand in Glove Concept - The Ocean Within

The Standard Model of Big Bang cosmology is one of the most widely accepted cosmological models today. It is factually correct and proven but still lacks the framework to explain several issues like where did the primordial atom come from, why 90% of gravity comes from an unknown substance called dark matter, why is the universe expanding because of an unknown substance called dark energy and what causes irregularities in the density field of the primordial universe seen directly in the CMB?
As such the Big Bang theory could just be a part of a currently undiscovered broader theory. Even though Einstein’s general relativity had shed a lot of light on gravity and how objects follow the curvature of spacetime, but he was unable to explain why it does so.
Due to lack of appropriate scientific instruments to dissect or unwrap the fabric of spacetime, one will need to rely heavily on theoretical reasoning to transcend its reality beyond our mortal sensory perception.
In my Hand in Glove (HIG) concept, I attempt to fill in these voids by theorizing the existence of a 5th dimension within our universe and that, it is liquid (ocean-like) in nature. I use the properties of water like surface tension (adhesion and cohesion), vacuum evaporation, desublimation and buoyancy to explain the possibility in the formation of the universe.
I then conclude that the underlying mechanism of how gravity acts is nothing but the buoyancy effect of an ocean-like medium present within our universe.
