, 2023 I have been working on the fundamental laws of physics for a long time. During this time, I realized that gravity does not work like Newtonian and this misleads us into Dark Matter. The relationship between distance and gravitational force varies with distance.

Humanities, 2021 This article argues that darkness contributes to the creation of, and expands the concept of, heterotopias. In Sarah Waters’s neo-Victorian trilogy, consisting of Tipping the Velvet (1998), Affinity (1999), and Fingersmith (2002), her characters utilize ...

Unifying dark matter, dark energy and inflation with a fuzzy dark fluid [PDF]
, 2020 Scalar fields appear in many cosmological models, in particular in order to provide explanations for dark energy and inflation, but also to emulate dark matter. In this paper, we show that it is possible for a scalar field to replace simultaneously dark matter, dark energy and inflation by assuming the existence of a non-minimal coupling to gravity, a ...

Enlightening the dark ages with dark matter [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Constraints on dark matter annihilation or decay offer unique insights into the nature of dark matter. We illustrate how surveys dedicated to detect the highly redshifted 21 cm signal from the dark ages will offer a new window into properties of particle dark matter.

Dark energy in the dark ages [PDF]
Astroparticle Physics, 2006 Non-negligible dark energy density at high redshifts would indicate dark energy physics distinct from a cosmological constant or ``reasonable'' canonical scalar fields. Such dark energy can be constrained tightly through investigation of the growth of structure, with limits of \la2% of total energy density at z\gg1 for many models.

Seeing Through the End Time: From Lord Byron’s “Darkness” to The Dark Mountain Project
Current Objectives of Postgraduate American Studies, 2015 This essay contends with the dark side of environmental literature by examining Lord Byron’s apocalyptic poem “Darkness“ (1816) ecocritically, drawing on Timothy Morton’s concepts of dark ecology “and ecological thought“ to ask how darkness functions in ...

Physics Letters B, 2003 Velocity-dependent interactions in a fundamental-string dominated universe lead quite naturally, with reasonable assumptions on initial conditions, to an accelerating expanding universe without assuming the existence of a cosmological constant. This result also holds generically for a universe dominated by moving extremal black holes, owing to a ...

Journal of Cosmology and Astroparticle Physics, 2009 The two dark sectors of the universe - dark matter and dark energy - may interact with each other. Background and linear density perturbation evolution equations are developed for a generic coupling. We then establish the general conditions necessary to obtain models free from early time non-adiabatic instabilities.

Lutter contre la pollution lumineuse
VertigO, 2019 The degradation of darkness through the use of artificial light at night (ALAN) in and around human infrastructures is termed light pollution. This pollution is intrinsically related to urbanization and spills out from urban areas to affect rural areas ...

Journal of Modern Physics, 2020 The prevailing cosmological constant and cold dark matter (LCDM) cosmic concordance model accounts for the radial expansion of the universe after the Big Bang. The model appears to be authoritative because it is based on the Einstein gravitational field equation.
