Aiming for Proxima Centauri b: Gravitational effects on relativistic spacecraft trajectories
Mark C. Baumann, Justin C. Feng, Nicky Ishaak
How important are gravitational and relativistic effects for interstellar travel? We consider this question in the context of proposed laser-propelled spacecraft missions to neighb…
Redshifted civilizations, galactic empires, and the Fermi paradox
Chris Reiss, Justin C. Feng
Given the vast distances between stars in the Milky Way and the long timescales required for interstellar travel, we consider how a civilization might overcome the constraints aris…
An asymptotic systems approach for the good-bad-ugly model with application to general relativity
Miguel Duarte, Justin C. Feng, Edgar Gasperín +1
We employ an adapted version of Hörmander's asymptotic systems method to show heuristically that the standard good-bad-ugly model admits formal polyhomogeneous asymptotic solutions…
Gravity limits the kinetic energy of a massive elementary particle
Justin C. Feng
In this note, I argue that tidal effects generically limit the kinetic energy of a single massive elementary particle in the vicinity of a compact object. As the kinetic energy is…
Probing the quantum nature of black holes with ultra-light boson environments
Soumodeep Mitra, Sumanta Chakraborty, Rodrigo Vicente +1
Quantum black holes (BHs), thought of as an excited multilevel system, can be effectively modelled by replacing an event horizon with a partially reflective membrane. This emergent…
