Machian Origin of the Entropic Gravity and Cosmic Acceleration
Merab Gogberashvili, Igor Kanatchikov
TL;DR
This paper explores how gravity and cosmic acceleration can be understood as emergent phenomena arising from thermodynamic principles and Machian ideas, linking entropic forces to the universe's horizon temperature.
Contribution
It proposes a Machian framework for deriving relativistic effects, gravity, and dark energy as entropic phenomena connected to the universe's horizon temperature.
Findings
Gravity can be derived as an entropic force from thermodynamic considerations.
Cosmic acceleration is related to the Hawking-Unruh temperature at the universe's horizon.
A Machian universe with a preferred frame explains relativistic effects and dark energy origins.
Abstract
We discuss the emergence of relativistic effects in the Machian universe with a global preferred frame and use thermodynamic considerations to clarify the origin of gravity as an entropic force and the origin of dark energy/cosmic acceleration as related to the Hawking-Unruh temperature at the universe's horizon.
