Tachyons and Gravitational Cherenkov Radiation
Charles Schwartz
TL;DR
This paper calculates the gravitational radiation emitted by hypothetical faster-than-light particles called tachyons, finding the emission rate to be extremely low, which has implications for their detectability and theoretical consistency.
Contribution
It provides a quantitative estimate of gravitational Cherenkov radiation emitted by tachyons, a novel calculation in the context of faster-than-light particles.
Findings
Emission rate of gravitational radiation is very small
Tachyons produce negligible gravitational Cherenkov radiation
Results impact the theoretical viability of tachyons
Abstract
We calculate the rate at which a free tachyon (faster than light particle) would emit gravitational radiation. It is very small.
