Violation of the strong Huygen's principle and timelike signals from the early Universe

TL;DR

This paper explores how violations of the strong Huygens principle enable more information from the early universe to reach us through timelike channels than through traditional light rays, impacting our understanding of cosmic information transfer.

Contribution

It demonstrates that violations of the strong Huygens principle allow for increased information transfer via timelike signals from the early universe.

Findings

Timelike channels carry more information than light rays.

Violations of the strong Huygens principle affect information transmission.

Implications for early universe cosmology and information theory.

Abstract

We analyze the implications of the violations of the strong Huygens principle in the transmission of information from the early universe to the current era via massless fields. We show that much more information reaches us through timelike channels (not mediated by real photons) than it is carried by rays of light, which are usually regarded as the only carriers of information.
