Journal ArticleDOI
Exact vacuum solution to conformal Weyl gravity and galactic rotation curves
TL;DR: In this paper, the exact exterior solution for a static, spherically symmetric source in locally conformal invariant Weyl gravity is presented, which includes the familiar exterior Schwarzschild solution as a special case and contains an extra gravitational potential term which grows linearly with distance.
Journal ArticleDOI
Alternatives to dark matter and dark energy
TL;DR: In this article, the authors review the underpinnings of the standard Newton-Einstein theory of gravity and identify where it could possibly go wrong, and discuss the logical independence from each other of the general covariance principle, the equivalence principle and the Einstein equations, and how to constrain the matter energymomentum tensor which serves as the source of gravity.
Journal ArticleDOI
No-Ghost Theorem for the Fourth-Order Derivative Pais-Uhlenbeck Oscillator Model
TL;DR: A new realization of the fourth-order derivative Pais-Uhlenbeck oscillator is constructed that possesses no states of negative norm and has a real energy spectrum that is bounded below.
Journal ArticleDOI
Making the Case for Conformal Gravity
TL;DR: In this paper, it was shown that the macroscopic classical theory that results from the quantum conformal theory incorporates global physics effects that provide for a detailed accounting of a comprehensive set of 138 galactic rotation curves with no adjustable parameters other than the galactic mass to light ratios.
Journal ArticleDOI
Fitting galactic rotation curves with conformal gravity and a global quadratic potential
TL;DR: In this paper, the authors apply the conformal gravity theory to a sample of 111 spiral galaxies whose rotation curve data points extend well beyond the optical disk, and detect the presence of a global de Sitter-like component and provide a specific value for its strength.
