Fluid Dynamics of Spacetime: Spacetime Currents as an Alternative to Dark Matter and Galactic Rotation

Key Points

This research aims to present a new theoretical model where spacetime is viewed as a fluid influencing cosmic dynamics.
Proposed a conceptual model of spacetime as a fluid with intrinsic density and defined viscosity.
Described the interaction of mass and energy with spacetime using the stress-energy tensor from General Relativity.
Analyzed how spacetime currents could explain observations in galactic rotation without dark matter.
Demonstrated that spacetime currents can replicate anomalous dynamics in galactic rotation curves effectively.
Provided a unified explanation for cosmic phenomena that traditionally required dark matter.
Outlined the implications for understanding fundamental physics through a fluid dynamic approach.

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 "spacetime 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.
