The expansion of the universe and the cosmological constant problem
Physics Letters A, 2007 The discovery that the expansion of the universe is accelerating in time is a major discovery which still awaits adequate explanation. It is generally agreed that this implies a cosmic repulsion as a result of the existence of a cosmological constant . However, estimates of the cosmological constant, based on calculations of the zero-point fluctuations

Leibniz on Compossibility: Towards a Neo‐Logical Interpretation
Theoria, EarlyView.ABSTRACT Leibniz's concept of compossibility explains why not all possible substances are actualised, thereby resisting Spinoza's necessitarianism. Yet, the precise basis of incompossibility remains unresolved. The influential ‘logical’ interpretation—exemplified by the Hintikka–D'Agostino thesis—locates incompossibility in contradictions among ...

Against Pluriversality: Epistemology, Ideology, and the Disavowal of Capitalist Antagonism
Antipode, Volume 58, Issue 5, September 2026.ABSTRACT Recent years have witnessed a dramatic surge of interest in decolonial pluriversality across critical geography, political ecology, and development studies. Advanced most prominently by scholars, such as Walter Mignolo and Arturo Escobar, pluriversality promises a world in which multiple ontologies, epistemologies, and lifeways coexist without

The Greatest Mystery of Futures Studies
FUTURES &FORESIGHT SCIENCE, Volume 8, Issue 2, August 2026.ABSTRACT Futures studies has long lived with a puzzle: every domain the field investigates is already studied by some special science. Three familiar replies—that futures studies extracts insights, takes a longer view, or includes lay perspectives—each capture something real but do not, on closer inspection, individuate the field at the level of its ...

A Small Cosmological Constant from a Large Number of Extra Dimensions
UniverseIn this article, we consider the 4 + n dimensional spacetimes among which one is the four dimensional physical Universe and the other is an n-dimensional sphere with constant radius in the framework of Lanczos-Lovelock gravity. We find that the curvature

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.

Green Emissions From Sprite Tops
Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.Abstract Although sprite discharges above thunderstorms have been studied for about 35 years, science enthusiasts reported the existence of long‐duration green light emissions from sprite tops only recently using commercial digital cameras and named these events green ghosts.

Searching for the beasts in the archive as methodological praxis
Geographical Research, Volume 64, Issue 3, August 2026.This article offers searching for the beasts in the archive as a methodological tool available to researchers invested in both anticolonialism and antianthropocentrism. By focusing on three basic units of reference—categories, histories, and borders—the article shows how searching for the beasts unsettles some taken‐for‐granted assumptions that ...
