The model of «viscous universe» is a new scientific proposal presented by international physicists who propose that dark energy It is not a constant, but an effect of the internal friction of the space-time fabric that accelerates cosmic expansion.
That is, space behaves like a fluid with internal resistance, which generates friction, instead of a vacuum.
This research presented in January 2026 by the researcher Muhammad Ghulam Khuwajah Khanfrom the Institute Indian Institute of Technology (IIT) Jodhpur breaks with the paradigm established by the cosmological constant of Einstein.
According to the new study, the space It is not an inert vacuumbut rather behaves like a fluid with specific mechanical properties. This internal resistance would explain why galaxies move away from each other at increasingly greater speeds without resorting to unknown external forces.

Mathematical analysis suggests that The viscosity of the cosmos acts as an engine of mass repulsion. By viewing space as a dynamic medium, scientists managed to adjust the equations of general relativity to match the most recent astronomical observations.
This approach eliminates several inconsistencies that the standard model of physics has not been able to resolve to date.
How viscosity impacts dark energy in space
The implementation of this theoretical framework allows a deeper understanding of the evolution of the early universe.
If the viscosity was greater in the past, the formation of galactic structures would have followed a different pattern than the one we know. This opens a new way to interpret data obtained by the next-generation space telescopes currently operating.
The researchers maintain that this change of vision facilitates the unification of various theories on the origin of matter. By integrating friction into the expansion calculation, the gap between quantum physics and large-scale cosmology is narrowed.
It is a fundamental step in building a theory of everything that is consistent with the physical reality observed in deep space.

This discovery also raises questions about the ultimate destiny of universal existence. Depending on how viscosity varies over time, the cosmos could face a different end than «Big Freeze».
The international scientific community has begun to review its simulations to adapt star maps to this new property of the space-time recently revealed.
This scientific advance redefines the limits of human knowledge about the origin of everything. The acceptance of a viscous cosmos will force specialists to rewrite textbooks, forever transforming our perception of infinity and its evolution.
