Why do we Need Observers? Spontaneous Breaking of Time-Reversal in de Sitter Space
Leonard Susskind
TL;DR
This paper explores how the presence of observers in de Sitter space relates to the spontaneous breaking of time-reversal symmetry, shedding light on fundamental aspects of spacetime physics.
Contribution
It establishes a connection between observer necessity and symmetry breaking in de Sitter space, offering new insights into spacetime structure.
Findings
Observers are essential for understanding symmetry breaking in de Sitter space
Spontaneous time-reversal symmetry breaking occurs in the presence of observers
The work clarifies the role of observers in fundamental spacetime properties
Abstract
In this paper I explain the relation between the need for observers in de Sitter space and the spontaneous breakdown of time-reversal symmetry.
