Calibration of Retrospective and Prospective Life Satisfaction Judgments Around the World
FUTURES &FORESIGHT SCIENCE, Volume 8, Issue 2, August 2026.ABSTRACT It is both a physical and psychological fact that humans have access to records of the past but not to records of the future. Due to this epistemic asymmetry in time, we hypothesized that retrospection about past psychological states will be better calibrated than prospection about future psychological states.

On the physical basis of cosmic time [PDF]
, 2008 In this manuscript we initiate a systematic examination of the physical basis for the time concept in cosmology. We discuss and defend the idea that the physical basis of the time concept is necessarily related to physical processes which could ...

Bianchi I Spacetimes in f(Q)‐Gravity
Fortschritte der Physik, Volume 74, Issue 8, August 2026.ABSTRACT The Kasner spacetimes are exact solutions that are self‐similar and of significant interest because they can describe the dynamic evolution of kinematic variables near the singularity of the Mixmaster universe. The chaotic behavior of the Mixmaster universe is related to the Kasner relations.

Testability and Epistemic Shifts in Modern Cosmology [PDF]
, 2012 During the last decade new developments in theoretical and speculative cosmology have reopened the old discussion of cosmology’s scientific status and the more general question of the demarcation between science and non-science. The multiverse hypothesis,

Relativistic Landau resonances [PDF]
, 2005 The possible interactions between plasma waves and relativistic charged particles are considered. An electromagnetic perturbation in the plasma is formulated as an elliptically polarized wave, and the collisionless plasma is described by a distribution ...

European Physical Journal C: Particles and Fields, 2023 We demonstrate a spontaneous tendency of quantum wave packets to become quasi-classical, providing a classical limit for the Universe dynamics. However, this limit is not maintained in the future (after a critical value of the relational time) and a ...

Fortschritte der Physik, Volume 74, Issue 8, August 2026.ABSTRACT We apply the boundary‐only isothermal formulation of finite‐distance weak gravitational deflection to regular black holes, black‐bounces, traversable wormholes, non‐asymptotically flat backgrounds, and static quadrupolar spacetimes. The methodological advance is not a new value for a known bending angle.

Relativistic Cosmology from the linear to the non-linear regime [PDF]
, 2018 Cosmology is a data-driven science and in the past decades we have seen the Lambda-Cold-Dark-Matter (Lambda-CDM) model establishing itself as the standard model for cosmology.

System Identification Based Models for Electron Fluxes Measured by GOES 16
Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.Abstract System identification is employed to develop a set of models to forecast the electron fluxes at geostationary orbit. The energy of the electron fluxes are based on the measurements of (GOES 16) (MPS‐HI). The GOES 16 generation of spacecraft measures a wide range of electron energies, 10 energy channels from 50 keV to 4 MeV, compared to its ...

The ΛCDM-NG Cosmological Model: A Possible Resolution of the Hubble Tension
The Astrophysical JournalWe offer a cosmological model based on conventional general relativity (no speculative physics) that may resolve the Hubble tension. A reanalysis of the foundation of the Lambda-CDM model shows that general relativity alone does not specify what fraction
