Galactic Tide

Galactic Tide

Tidal forces are depending on the gradient of a gravitational field, as opposed to its strength, and for that reason tidal effects tend to be limited to immediate surroundings of an galaxy. A galactic wave is tidal pressure experienced by objects governed by the gravitational field of an galaxy including the Milky Way. Particular elements of galactic tide consist of galactic collisions, disruption of dwarf or even satellite galaxies and the Milky Way’s tidal effect on the Oort cloud from the Solar System.
