The Great Cosmic Silence: What Does the Fermi Paradox Tell About the Future of Humanity?
Global Policy, EarlyView.ABSTRACT This article examines how institutional time horizons shape the long‐term survival prospects of human technological civilisation. While research on global catastrophic and existential risks has expanded, the temporal structures of political‐economic institutions remain underexamined.

The Cosmological constant and the coincidence problem in a new cosmological interpretation of the universal constant “c” [PDF]
International Journal of Theoretical Physics, 2009 In a recent paper (Vigoureux et al. Int. J. Theor. Phys. 47:928, 2007) it has been suggested that the velocity of light and the expansion of the universe are two aspects of one single concept connecting space and time in the expanding universe. It has then be shown that solving Friedmann's equations with that interpretation (and keeping c = constant ...

The Mutable Original: How Chinese Counterfeits Become Nigerian Originals in African Markets
American Anthropologist, EarlyView.ABSTRACT Affordable Chinese copies of Western brands are ubiquitous in African markets. Despite democratizing consumer access, these goods appear to cement hegemonic value hierarchies that rank Chinese or local products as inferior to Western goods.

Anthropology of Consciousness, EarlyView.ABSTRACT This essay examines the controversy surrounding the Bhoot Vidya certificate program proposed by the Faculty of Ayurveda at Banaras Hindu University in 2019. Drawing on media coverage, curricular materials, and government policy, I analyze how the debate reveals broader tensions in the politics of contemporary Ayurveda, nationalism, and ...

Topology‐based Visual Analysis of Hydrothermal Plumes
Computer Graphics Forum, EarlyView.Abstract Hydrothermal plumes are turbulent structures of intense heat and mineral smoke that rise and disperse into the deep ocean. Existing models generally characterize these systems as a single axisymmetric plume originating from a point source. However, this assumption breaks down in weakly venting, spatially distributed systems, where low‐flux ...

The cosmological nature of the dark Universe
European Physical Journal C: Particles and Fields, 2018 This paper deals with the cancellation mechanism, which identifies the energy density of space-time expansion in an empty universe with the zero-point energy density and avoids the scale discrepancy with the observed energy density (cosmological constant

Scalable Computation of Topological Abstractions for Scalar Data
Computer Graphics Forum, EarlyView.Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

A speculative approach to quantum gravity
Electronic Journal of Differential Equations, 2000 The bare bones of a theory of quantum gravity are exposed. It may have the potential to solve the cosmological constant problem. Less certain is its behavior in the Newtonian limit.

Crunching away the cosmological constant problem: dynamical selection of a small Λ
Journal of High Energy Physics, 2020 We propose a novel explanation for the smallness of the observed cosmological constant (CC). Regions of space with a large CC are short lived and are dynamically driven to crunch soon after the end of inflation.
