From kinetic gases to an exponentially expanding universe - The Finsler-Friedmann equation
Christian Pfeifer, Nicoleta Voicu, Annamaria Friedl-Szász +1
We investigate the gravitational field of a kinetic gas beyond its usual derivation from the second moment of the one-particle distribution function (1PDF), that serves as energy-m…
