We apply the perturbative technique which was previously developed in cosmology to now describe the gravitational field of a galaxy with arbitrary rotation curve. We use a Schwarzschild background as starting point,…

Speculation on the Number 137 in the Inverse FineStructure Constant
The inverse fine-structure constant 1/α = 137.035 satisfies 1/α = 112+ 42 + 0.035 = 137.035, with 11 being the 11 dimensions of M-theory, 4 the number of dimensions of Einstein’s space-time,…
Determining the Cosmological Constant Using Gravitational Wave Observations: Recent Advancements
It is shown in Einstein gravity that the cosmological constant Λ introduces a graviton mass mg into the theory, a result that will be derived from the Regge-Wheeler-Zerilli problem for a particle…
