This article proposes a fluid mechanics-inspired perspective to explore galactic dynamics and spacetime curvature. It suggests that spacetime can be considered as a fabric under tension, influencing the trajectory of galaxies analogously to particles in a viscous fluid. The presented visualization artistically reflects this concept, showing galaxies moving over a concave surface akin to a convex lens, moving away from the center and towards the edges, akin to the behavior of viscous fluid droplets on a slanted surface. This model offers an opportunity to rethink cosmological theories and could provide new avenues for interpreting astronomical observations.

In this article, we introduce the concept of "Quantum Expansion Rate", a novel measure in the field of quantum cosmology that seeks to establish a connection between the microscopic properties of light and the large-scale expansion of the universe. The quantum expansion rate, \(v_u\), is defined through a relationship between the speed of light in a vacuum, the wavelength of light, and a specific reference distance. Through mathematical analysis, we explore how different reference wavelengths can influence \(v_u\), revealing potential implications of this factor on the universe's expansion rate. The relevance of these findings in the context of the universe's early events, such as particle annihilation, and their potential impact on the cosmos's structure and evolution, is discussed. The proposal of  as a tool for understanding the interaction between quantum mechanics and cosmology raises significant questions and opens new avenues for future research.

This article examines the quantum mechanics of the vacuum, highlighting its evolution from a concept of absolute "nothingness" in classical physics to a space of effervescent quantum activity. The Schrödinger equation and its relevance to understanding the dynamic nature of the vacuum are discussed, along with the Heisenberg Uncertainty Principle and its implications for quantum fluctuations in the vacuum. The zero-point energy, the cosmological constant and its relationship with the expansion of the universe, and the Casimir effect are also addressed. The article concludes with a review of emerging practical applications in fields such as quantum computing, space propulsion, and quantum cryptography, and reflects on the promising future of vacuum physics.

This hypothesis explores the possibility of a function that describes how the effective mass of a particle changes over time during a quantum process. We introduce a Temporal Mass Function, \(m(t)=m_0e^{-λt}\) , to reflect changes in the energy and properties of the particle, particularly in the context of deferred annihilation. Substituting this function into Einstein's equation, \(E=mc^2\) , we obtain a new energy-time equation that shows how the energy of the particle changes due to the variation of its mass. The temporal derivative of this equation reveals that the rate of change of the particle's energy decreases over time, suggesting a novel quantum interpretation of annihilation. Furthermore, we propose replacing the constant speed of light, , with a constant representing the Universe's expansion speed, , leading to a reformulation of the mass-energy equation as . This approach suggests that a particle's energy could be linked to the expansion of space itself, raising significant questions about the relationship between mass, energy, and the expansion of the Universe in the quantum context.
