A derivation of Weyl gravity
In this paper, two things are done. (i) Using cohomological techniques, we explore the consistent deformations of linearized conformal gravity in 4 dimensions. We show that the only possibility involving no more than 4 derivatives of the metric (i.e., terms of the form ∂gμν , ∂gμν∂gαβ , ∂ gμν∂ gαβ , ∂ gμν∂gαβ∂gρσ or ∂gμν∂gαβ∂gρσ∂gγδ with coefficients that involve undifferentiated metric compone...
متن کاملO Brave New World: The Dark Side of Cyberspace
This article focuses on some of the negative aspects of cyberspace andcyberculture. First, it offers an examination of the impact of our use ofsocial media, and Facebook in particular, on our psyches, pointing out thatusers of social media can be thought of as audiences. These audiencesand information about them can be sold to marketers and advertisers.Next, it offers a case study of a widespre...
متن کاملThe dark side of cosmology: dark matter and dark energy.
A simple model with only six parameters (the age of the universe, the density of atoms, the density of matter, the amplitude of the initial fluctuations, the scale dependence of this amplitude, and the epoch of first star formation) fits all of our cosmological data . Although simple, this standard model is strange. The model implies that most of the matter in our Galaxy is in the form of "dark...
متن کاملConformal Gravity: Dark Matter and Dark Energy
This short review examines recent progress in understanding dark matter, dark energy, and galactic halos using theory that departs minimally from standard particle physics and cosmology. Strict conformal symmetry (local Weyl scaling covariance), postulated for all elementary massless fields, retains standard fermion and gauge boson theory but modifies Einstein–Hilbert general relativity and the...
متن کاملDark Energy and Dark Gravity : Theory Overview
Observations provide increasingly strong evidence that the universe is accelerating. This revolutionary advance in cosmological observations confronts theoretical cosmology with a tremendous challenge, which it has so far failed to meet. Explanations of cosmic acceleration within the framework of general relativity are plagued by difficulties. General relativistic models are nearly all based on...
