Reduced Total Energy Requirements for a Modified Alcubierre Warp Drive Spacetime

TL;DR

This paper proposes a modified Alcubierre warp drive spacetime that significantly reduces negative energy requirements by introducing a lapse function, explores quantum inequalities, and suggests a method for superluminal warp bubble control.

Contribution

It introduces a lapse function into the Alcubierre metric to arbitrarily reduce negative energy needs and presents a pseudo method for controlling superluminal warp bubbles.

Findings

Negative energy requirements can be greatly reduced.

Quantum inequality restrictions are generalized.

A pseudo method for superluminal warp bubble control is proposed.

Abstract

It can be shown that negative energy requirements within the Alcubierre spacetime can be greatly reduced when one introduces a lapse function into the Einstein tensor. Thereby reducing the negative energy requirements of the warp drive spacetime arbitrarily as a function of A(ct,r_s). With this function new quantum inequality restrictions are investigated in a general form. Finally a pseudo method for controlling a warp bubble at a velocity greater than that of light is presented.
