Doppler shift frequency is equal to the change in velocity
Of the source divided by its velocity, times the observed velocity
And in electromagnetic radiation has a different name
Of Redshift or blueshift coming or going its all the same
Redshifts , blueshifts answer to the letter “z”
And others in wavelengths too short to see
And so the universe is flying apart
Doing nothing more than its preordained part
Gets a boost from dark energy and dark matter
Whose high energy photons scatter
And sometimes back to us and some we never see
Running away from us whose sight can never be
For there is a light barrier at 4906
Whose distance holds photons just for kicks
Four thousand nine hundred and six
Mega parsecs sticks
Light from ever reaching you and me
It’s sixteen billion light-years you see
And the galaxies redshifted past Z<=1.4
Are faster than the speed of light forevermore
Just beaming towards us caught in a cosmological undertow
That pulls it ever-on towards infinity whose celestial wind blows
It till the very essence of time standing still
And the stars all wink out and energy becomes nil

We have all been told that faster than light speeds are not possible that mass become infinite as the speed increases. This is a relative term. It just depends upon the place the two events occur. There are galaxies that are redshifting with "Z" factors exceeding Z=1.4 This recession is faster than light.
