Although the time dilation due to velocity is negligible, what might apply is the retarded time. You may be able to modify Jefemenko's electromagnetic equations to apply to a gravitational context....

As John Rennie mentioned, a galaxy is not relativistic (speed too low, gravitational field also). So, the Ehrenfest paradox does not apply. On the other hand, if a galaxy compacts itself towards the...

The orbital velocity of the Sun within the Milky Way is around 230 km/sec, and we can use this speed to calculate how big the relativistic effects would be. The relevant quantity is the Lorentz factor,...

The observed paths and speeds of objects, part of some distant galaxy, do not match up with speed vs distance curves it seems - the observed speeds are not falling off in fact they're trending as...
