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 ...

It also means that tidal forces would begin to overwhelm the explorer only during the last 0.00346 second of the journey, a time so short “you’d never know what hit you,” says Gott.

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 ...
