The physics of space and time II: A reassessment of Einstein's 1905 special relativity paper

Abstract

A detailed re-examination of the seminal paper on special relativity, taking into account recent work on the physical interpretation of the space-time Lorentz transformation as well as the modern understanding of classical elecromagnetism as a certain limit of the fundamental underlying theory --quantum electrodynamics-- is presented. Many errors both of physical principle and of a mathematical nature are uncovered. The `relativity of simultaneity' and `length contraction' effects predicted in the paper are shown to be the spurious consequences of misinterpretations of the second postulate and the Lorentz transformation, respectively. The derivation of the latter in the paper is shown to be flawed. In this case, and other instances, due to cancellation of mistakes, a correct result is obtained in a fallacious manner. Separate lists of the correct and incorrect predictions of the paper are given. Due to the unique and revolutionary nature of its epistemological approach (the use of `thought experiments' and axiomatic derivations) and the experimentally verified predictions of time-dilatation and mass-energy equivalence the fundamental importance of the paper for the development of physics is little affected by the many mathematical errors and (to modern eyes) physical misconceptions that it contains.

Fermions can also produce super-radiation phenomena

According to traditional theory, it is believed that Fermions do not exhibit superradiation. However, when predetermined boundary conditions are in place, there is a possibility of combining the wave function of coupled Fermions, which can result in the emergence of superradiation phenomena. This article presents a novel perspective, proposing that Fermions have the potential to display superradiation phenomena. This implies that there is a broader scope for investigating superradiation and its relationship with boundary conditions.

All About the Galilean Group SGal(3)

We consider the Galilean group of affine transformations that preserve absolute time intervals between events in spacetime, as well as spatial distances between simultaneous events. The special Galilean group, SGal(3), is a 10-dimensional Lie group; we examine the structure of the group and its Lie algebra and discuss the representation of uncertainty on the group manifold. We also derive closed-form expressions for the $\LieGroupSGal{3}$ exponential and logarithmic maps, the Cayley and inverse Cayley maps, and the left Jacobian and its inverse. Along the way, we mention other groups, including the special orthogonal group, the special Euclidean group, and the group of extended poses, all of which are proper subgroups of the special Galilean group. We describe the role of time in Galilean relativity and touch on the relationship between temporal and spatial uncertainty.

Constraints on Rastall gravity from current observational data

We study the cosmological features of Rastall gravity, where the covariant energy-momentum conservation is modified to $\nabla_μT^μ_ν=λ\nabla_νR$ in curved spacetime. For this purpose, we obtain the modified field equations of Rastall model to linear order of perturbations, and then inspect the evolutionary behavior of cosmological observables, chiefly the matter power spectrum and the Hubble parameter, within the context of Rastall gravity. We also compare Rastall model with cosmological probes, namely cosmic microwave background, weak lensing, supernovae, baryon acoustic oscillations, and redshift-space distortions data. According to our numerical results, Rastall gravity prefers lower growth of structures compared to the $Λ$CDM model, which indicates consistency with low-redshift large-scale structure probes. Moreover, numerical analysis reveals that Rastall gravity with a cosmological constant as the dark energy component suffers from the Hubble tension, like the $Λ$CDM model.
