Gravitational wave ‘radar’ could help map the invisible universe
Such “GRADAR” signals could spot globs of dark matter
or very distant neutron stars

It sounds like the setup for a joke: If radio waves give you radar and
sound gives you sonar, what do gravitational waves get you?

Gravity mysteries: Why is gravity so weak?

Gravity is a real weakling – 10^40 times weaker than the electromagnetic force that holds atoms together.

Gravitational waves are, after all, aether waves. We can even perceive inertial motion as a specific gravitational wave. In the way a photon moves… However, this presupposes an undescribed type of field - “gravitational magnetism”. It would also help us to understand the motion of stars in galaxies, thus eliminating the need to search for "dark" matter :)

?

A "gravitational magnetic" field is created around the moving body, which keeps an inertial motion similar to a propagating photon. Such a field can, for example, cause moving stars in a galaxy to be affected not only by immediate "radial" transverse gravity, but also by "shared" longitudinal thrust…
