Events as Elements of Physical Observation: Experimental Evidence

Autor: J. Gerhard Müller

Publikováno v: Entropy, Vol 26, Iss 3, p 255 (2024)

It is argued that all physical knowledge ultimately stems from observation and that the simplest possible observation is that an event has happened at a certain space–time location X→=x→,t. Considering historic experiments, which have been grou

Joint reconstructions of growth and expansion histories from stage-IV surveys with minimal assumptions II: Modified gravity and massive neutrinos

Based on a formalism introduced in our previous work, we reconstruct the phenomenological function $G_{\rm eff}(z)$ describing deviations from General Relativity (GR) in a model-independent manner. In this alternative approach, we model $\mu\equiv G_

The Cosmological Principle (CP) -- the notion that the Universe is spatially isotropic and homogeneous on large scales -- underlies a century of progress in cosmology. It is conventionally formulated through the Friedmann-Lema\^itre-Robertson-Walker

A Cautionary Tale: Dark Energy in Single-Field, Slow-Roll Inflationary Models

Autor: Castello, Sveva, Ilić, Stéphane, Kunz, Martin

The current epoch of accelerated cosmic expansion is postulated to be driven by dark energy, which in the standard model takes the form of a cosmological constant with equation of state parameter $w=-1$. We propose an innovative perspective over the
