Hubble tension and fifth forces
, 2023 Fifth forces are ubiquitous in modified theories of gravity. In this paper, we analyze their effect on the Cepheid-calibrated cosmic distance ladder, specifically with respect to the inferred value of the Hubble constant (H0).

Batteries &Supercaps, Volume 9, Issue 5, May 2026.Lithium‐ion batteries used in space applications are exposed to extreme conditions, including radiation, vacuum, wide temperature fluctuations, and long storage times, all of which accelerate degradation. This review article summarizes the main degradation mechanisms affecting battery performance in space environments, including capacity fade ...

Tension in the Hubble constant
, 2017 There has been some hand-wringing of late about the tension between the value of the expansion rate of the universe – the famous Hubble constant, H <sub> 0 </sub> , measured directly from observed redshifts and distances, and that obtained by

Can Inflation Resolve the Hubble Tension?
UniverseIn this work, we investigate how a change in the sound horizon due to inflation may affect the value of H0. Performing an analysis using the measurements of BAO, SN Ia, H(z), CMB, and the local H0, we show that the modification in the sound horizon ...

A Possible Solution to the Mystery of the ANITA Anomalous Events
Annalen der Physik, Volume 538, Issue 4, April 2026.In 2006 and 2014, the Antarctic Impulsive Transient Antenna (ANITA), a balloon‐borne radio observatory flying over Antarctica, detected two strange upward‐going radio pulse events that have not yet been explained by our current understanding of physics.

British Educational Research Journal, Volume 52, Issue 2, Page 864-885, April 2026.Abstract This paper challenges the prevailing assumption that technology‐enhanced learning (TEL) inherently benefits all students in higher education, examining how undergraduate students with specific learning differences (SpLDs) and/or autism spectrum disorder (ASD) use technology for learning.

Clarifying the Hubble Constant Tension
, 2019 Our best estimate of the Universe's current expansion rate (the Hubble constant) from the local Universe (via the Cepheid distance ladder) is in four-sigma tension with the value extrapolated from cosmic microwave background data assuming the standard ...

Fast radio bursts as cosmological proxies: estimating the hubble constant
Frontiers in Astronomy and Space SciencesOne of the most challenging problems in modern cosmology is the Hubble tension, a discrepancy in the predicted expansion rate of the Universe with different observational techniques that results in two conflicting values of H0.

Fortschritte der Physik, Volume 74, Issue 4, April 2026.Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.
