Constant Velocity Physical Warp Drive Solution

Jared Fuchs, Christopher Helmerich, Alexey Bobrick, Luke Sellers, Brandon Melcher, Gianni Martire

Abstract

Warp drives are exotic solutions of general relativity that offer novel means of transportation. In this study, we present a solution for a constant-velocity subluminal warp drive that satisfies all of the energy conditions. The solution involves combining a stable matter shell with a shift vector distribution that closely matches well-known warp drive solutions such as the Alcubierre metric. We generate the spacetime metric numerically, evaluate the energy conditions, and confirm that the shift vector distribution cannot be reduced to a coordinate transformation. This study demonstrates that classic warp drive spacetimes can be made to satisfy the energy conditions by adding a regular matter shell with a positive ADM mass.

    • The universe is 13.8 billion years old. The JWST has found galaxies formed just 400 million years after the Big Bang. It took the earth 4.6 billion years to form, and 1 billion years to create life. Our best theory of the universe, General Relativity, has solutions that allow…

    • > not moving fast: so where does the time dilation come from?! I think it’s from shifting momentum?? The paper is far beyond me [1]. But as I understood it, you’re directly modifying space-time with energy instead of using acceleration as a go-between. [1]…
