Hi, I observe a strong analogy between spacetime and Bernoulli's principle: The proof of Bernoulli's principle is based on the conservation of energy, which translates into a relationship between static and dynamic pressure: Static pressure + dynamic pressure = total pressure That is, when the velocity of the fluid increases (the energy of the water molecules increases), the dynamic pressure increases and the static pressure decreases. Spacetime bends when the energy of a particle increases. This curvature is at the origin of the gravity. The analogy is between the spacetime curvature caused by the energy and the conservation of energy which induces a pressure drop when the velocity of the fluid increases. The universe is composed of 95% of matter and energy still unknown today. Could it be that spacetime is totally granular? Aren't the main parameters that make up the movement (time, distance, speed, ...) derived totally from energy? I started from this analogy to develop a theory on the nature of energy that you will find in this link: https://docs.google.com/document/d/1VlfLrGBI_g_xi3Ta8nnv3z4dQ_f-N3g5iLXDyvMHsco/pub ''The idea developed in this article is that energy, space and time are the direct result of interactions between particles. Each particle has an amount of substance. A particle is composed of material contained in a finite volume, it therefore has a volumetric material density. Volumetric material density fluctuations are at the origin of many physical phenomena such as time, energy, movement of particles, accelerating expansion of the universe, etc.'' I have absolutely no pretention, although the subject is very ambitious. Get feedback to build an interesting discussion of physics is my goal.
