A Phase Space Diagram for Gravity

In modified theories of gravity including a critical acceleration scale a0, a critical length scale rM = (GM/a0) will naturally arise with the transition from the Newtonian to the dark matter mimicking regime occurring for systems larger than rM . This adds a second critical scale to gravity, in addition to the one introduced by the criterion v < c of the Schwarzschild radius, rS = 2GM/c. The d...

Gravity Wave Watching

It is suggested that gravity waves could, in several cases, be detected by means of already (or shortly to be) available technology, independently of current efforts of detection. The present is a follow-up on a recently suggested detection strategy based on gravity-wave-induced deviations of null geodesics. The new development is that a way was found to probe the waves close to the source, whe...

Gravity Wave Lensing

Here we show that a nonlinear resonance between oceanic surface waves caused by small seabed features (the so called Bragg resonance) can be utilized to create equivalent of lenses and curved mirrors for surface gravity waves. Such gravity wave lenses, which are merely small changes to the seafloor topography and therefore are surface non-invasive, can focus/defocus energy of incident waves tow...

A Macroscopic Gravity Wave Effect

Gravitational waves, although generally associated with extremely microscopic effects, can displace by hundreds of kilometers the pulsar interstellar scintillation patterns that bathe the Earth. The combination of the pulsar and the interstellar medium acts as a kiloparsec-long, nature-provided gravity wave amplifier. We show how an effective scheme for the detection of periodic gravity waves c...
