The 'viscous universe' model presents a revolutionary perspective on dark energy, proposed by international physicists, led by Muhammad Ghulam Khuwajah Khan from the Indian Institute of Technology (IIT) in Jodhpur. Unlike the traditional view, this model posits that dark energy is not a fixed entity but rather an effect of friction within the space-time continuum, which creates internal resistance. This friction, akin to the behavior of a fluid, leads to the observed acceleration in the cosmic expansion without necessitating any external forces.

According to this new research, space does not function as an inert vacuum but possesses mechanical properties that resemble a fluid, which enables it to push galaxies away from each other at increasing speeds. This hypothesis breaks away from Einstein's cosmological constant, which has long been relied upon to understand the universe's expansion. The implications of this model could dramatically alter our comprehension of cosmological dynamics and the fundamental nature of the universe.

The mathematical analysis conducted in this study indicates that the viscosity of cosmic space could serve as a thrusting mechanism behind the repulsion observed in the universe. This groundbreaking perspective could pave the way for new theories about gravitational forces and matter's interaction within the cosmos, thereby reshaping future research in cosmology and fundamental physics.
