Goswami and Ellis say that tidal forces are a form of gravitational radiation. But to be waves, they must vary in time in a special way dictated by the general theory of relativity.

Moreover, there is little high-resolution observation on how tidal forces affect the changes in seismic wave speed within the fault zone over time.

Tidal Forces May Have Shaped Tectonic Features. A research team from the University of Bern recently constructed physical models to examine how the Sun’s gravity might be impacting Mercury’s ...

Image showing a solar flare on Dec. 19, 2014. NASA/SDO. The Tayler instability can react to small changes to tidal forces—with a small shift creating perturbations on the sun.

Tidal forces acting upon the moon early in its history gave it the shape it holds now, according to new research. The shape of the moon deviates from a simple sphere in ways that scientists have ...

Get Instant Summarized Text (Gist) Tidal forces induce distinct diurnal, semi-diurnal, and monthly cycles in seismic wave velocity within fault fracture zones, correlating with periodic tidal strain.
