Very well.

Newton equations for gravity look like Coulomb equations for
electrostatic forces. Both are forces whose strength decreases with
inverse square distance, because the divergence of the field is
pro****tional to the density of mass and charge respectively.

The one difference is that like m***** attract while like charges
repel.

It turns out that there is also a gravitomagnetic field - a field with
curl rather than divergence, which will exert a Lorenz force on moving
m***** perpendicular to the direction of movement.

Gravitomagnetic field is generated by moving m***** as well as by the
displacement current of changing gravitoelectric fields.

And while stationary gravitomagnetic field force only affects moving
m*****, changing gravitomagnetic field will induce curl of
gravitoelectric field!

This ability of changing gravitomagnetic and gravitoelectric fields to
induce curls to one another is what enables gravity to travel as
gravitational waves.

However, the existence of gravitomagnetic fields raises the question
of how a gravitomagnetic monopole ought to behave...
