Key Points

To propose a fluid dynamics model of spacetime that explains galactic rotation without dark matter.
Postulated spacetime as a fluid with constant density
Analyzed interactions of mass and energy with this medium
Described gravitational currents resulting from viscosity
Proposed gravitational currents as causes of anomalous galactic rotation
Eliminated the need for dark matter in explaining cosmic dynamics
Suggested a unified framework for large-scale cosmic behavior

Abstract

This paper proposes an alternative theoretical framework for understanding large-scale cosmic dynamics. We postulate that spacetime is not an inert void, but rather a fluid with an intrinsic and constant density (ρST). In this conception, moving mass and energy (described by the stress-energy tensor of General Relativity), by interacting with this dense medium and with a certain viscosity, exert a direct "traction" that generates macroscopic currents and flow patterns in the very fabric of spacetime (vST). We argue that these "gravitational currents" are the true agents behind the anomalous dynamics observed in galactic rotation curves, offering a unified explanation that eliminates the need to postulate the existence of dark matter.
