This should cover the “relativistic Doppler Effect”, Einstein’s general relativity equations, their solution by Schwarzschild,
WebGravitational waves (GWs) from compact binary coalescences encode the absolute luminosity distances of GW sources. Once the redshifts of GW sources are known, one … WebHubble found a linear relationship between distance and redshift v = cz = H o d where Ho is a constant of proportionality, now called the Hubble Constant . Hubble's finding implies that the more distant a galaxy, the larger the recession velocity. This leads directly to the expansion of the universe, which we will discuss in some detail.
