Symmetry between inertial and gravitational mass results in general relativity. Orbits can decay via the emission of gravitational waves. The model is in agreement with recent astrophysical measurements using gravitational lensing. Such effects are known as gravitational lensing. Such an interaction prevents the formation of a gravitational singularity. This is another category containing galaxies with tidal tails produced by gravitational interactions. Magnetic and gravitational forces are generally negligible. These equations are used to study phenomena such as gravitational waves. This can be any of a number of mechanical, gravitational, or electromagnetic effects. Astronomers hope that the same holds true of gravitational waves. The mission will also complete gravitational and magnetic field mappings. It was detected by gravitational microlensing. Michelson interferometry is the leading method for the direct detection of gravitational waves. One hypothesis is formation by the gravitational instability. Other work terms, such as those involving electric, magnetic or gravitational fields may be added.
