# Red Shift Distances Using Hubble Constant

This content was updated and posted, moving out of research.

Hubble's Constant seems to vary among objects in Wikipedia with both an accepted distance and velocity. The H value is easily calculated with V / D. A random sample finds different H values are being used. A different H selection means this object's distance is not consistent with others.

Astronomers claim Hubble's Law can translate a red shift into a distance but it appears astronomers use varying values of Hubble's Constant for different objects.
This constant converts a velocity (in km/s) into distance (Mpc), where Distance = Velocity / H

From Wikipedia:
'
The Hubble constant is about 70 (km/s)/Mpc.

More recent measurements from the Planck mission published in 2018 indicate a lower value of 67.66±0.42% although, even more recently, in March 2019, a higher value of 74.03±1.42% has been determined using an improved procedure involving the Hubble Space Telescope. The two measurements disagree at the 4.4-sigma level, beyond a plausible level of chance.

Since the object's velocity is coming from an atom's absorption or emission line there is no assurance that a red shift actually corresponds to the velocity of the object behind the atom.

Here are several objects with their red shift velocity and the accepted distance (data from Wikipedia), with the corresponding H value for that combination.

V = km/s, D= Mpc
accepted values

M104 Z = 0.003416 V = 1024 at D = 9.55 so from V/D  H= 107.23

calculated from Z:
M104 Z = 0.003416 so V = 1024.8  with H = 72 then D = 14.23
M104 Z = 0.003416 so V = 1024.8 with H=107 then D = 9.58

M104 used a higher H than 'normal' 70.
accepted values
M60 Z = 0.003726 V = 1108 at D = 17.8 so from V/D H= 62.25

calculated from Z:
M60 Z = 0.003726 so V = 1117.8  with H = 72 then D = 15.53
M60 Z = 0.003726 V = 1117.8  with H = 62 then D = 18.0

M60 used H lower than 'normal' 70.

accepted values
Hoag's Object V = 12740 at D = 187.9 so from V/D H= 67.8
calculated from V:
Hoag's Object V = 12740 with H=70 then D = 182.0

Hoag's Object used H near 'normal' 70.

accepted values
Abell 133 Z = 0.00566 V = 16968 at D = 234 so from V/D H= 72.51

calculated from Z:
Abell 133 Z = 0.00566 V = 16968  with H = 72 then D = 235.83

Abell 133 used H higher than 'normal' 70.

accepted values, Z & D
3C 273 Z = 0.158339 so V = 47501.7 at D = 749 so from V/D H= 63.42

calculated from Z:
3C 273 Z = 0.158339 so V = 47501.7 with H = 70 then D = 678.6
3C 273 Z = 0.158339 so V = 47501.7 with H = 63 then D = 754

3C 273 used H lower than 'normal' 70.

I will add more objects if I notice any worthy of special interest.
