Future spaceflight will require a new theory of propulsion; specifically one that does not require mass ejection. A new theory is proposed that uses the general view that closed currents pervade the entire universe and, in particular, there is a cosmic mechanism to expel matter to large astronomical distances involving vortex currents as seen with blazars and blackholes. At the terrestrial level, force producing vortices have been related to the motion of wings (e.g., birds, duck paddles, fish's tail). In this paper, vortex structures are shown to exist in the streamlines aft of a spaceship moving at high velocity in the vacuum. This is accomplished using the density excitation method per a modified Chameleon Cosmology model. This vortex structure is then shown to have similarities to spacetime models as Warp-Drive and wormholes, giving rise to the natural extension of Hawking and Unruh radiation, which provides the propulsive method for space travel where virtual electron-positron pairs, absorbed by the gravitational expansion forward of the spaceship emerge from an annular vortex field aft of the spaceship as real particles, in-like to propellant mass ejection in conventional rocket theory.

Whirling maple seeds create vortex to fly high and far
The researchers from Wageningen University in the Netherlands and the California Institute of Technology (Caltech) in the US discovered that the whirling action of the maple seeds produces a leading edge vortex - a spinning horizontal tunnel of air along the wing. Air pressure is lowered over the upper surface of the maple seed, which draws the wind upward to oppose gravity and give it a boost, according to the researchers. The vortex doubles the lift produced by the seeds, against seeds that do not swirl. The vortex's ability to magnify the lift can be compared to the mechanism used by birds, insects and bats when they flap their wings to help them hover.
