Three recent articles have claimed that it is possible to, at least in theory, either set up
positive energy warp drives satisfying the weak energy condition (WEC), or at the very least …

Warp drives in Einstein's general theory of relativity provide a unique mechanism for
manned interstellar travel. It is well-known that the classical superluminal soliton spacetimes …

Relativistic quantum systems exhibit unique features not present at lower energies, such as
the existence of both particles and antiparticles, and restrictions placed on the system …

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 …

The field of warp research has been dominated by analytical methods to investigate
potential solutions. However, these approaches often favor simple metric forms that facilitate …

The Alcubierre metric describes a spacetime geometry that allows a massive particle inside
a spacetime distortion, called warp bubble, to travel with superluminal global velocities. In …

We show that the Laser Interferometer Gravitational Wave Observatory (LIGO) is a powerful
instrument in the Search for Extraterrestrial Intelligence (SETI). LIGO's ability to detect …

Solitons in space–time capable of transporting time-like observers at superluminal speeds
have long been tied to violations of the weak, strong, and dominant energy conditions of …

In this work we introduce the Alcubierre warp metric using spherical symmetry. In this way
we write the Einstein equations for a perfect fluid and for an anisotropic fluid with …

What happens when a warp bubble has mass? This seemingly innocent question forces one
to carefully formalize exactly what one means by a warp bubble, exactly what one means by …
