Hubble Constant

[Mike C]

A young PhD named William on another science forum supplied this information.

Some other pitfalls here, are for one, the distance to the Virgo cluster. This 16.7 Mpc is not as rock solid as you may think. Here is some more data on the distance to the Virgo cluster (notice the range of values and uncertainties);

 

Method: Distance (Mpc):

 

Cepheids: 14.9+/-1.2

Novae: 21.1+/-3.9

PN L-function: 15.4+/-1.1

Glob. cluster L function: 18.8+/-3.8

Surface brightness fluctuations: 15.9+/-0.9

Tully-Fisher relation: 15.8+/-1.5

D-sigma relation: 16.8+/-2.4

Type Ia SN: 19.4+/-5.0

 

So with that information, I got the idea for eliminating all these different methods with a new method of using the 'Centers of Gravity' (CoG) in the galactic clusters as the Hubble Paradigm.

 

Of the 8 methods above, notice that the SN1a's have the largest error margin.

As I said, I do not give them much credibility.

The Novae also ‘depart’ considerably from the others.

 

The galactic clusters are most likely to have giant elliptical galaxies in the centers of their clusters. All one needs to do is to locate these galactic clusters and any central ellipticals to evaluate their masses and velocities to locate the CoG for these most massive of galaxies. This can be easily done.

Then determine the recessional velocity (RV) and transform that to the redshift for that cluster.

Then this redshift can be applied to all the surrounding galaxies since they are all moving around the CoG for that cluster.

This then reduces the Hubble Constant to just ONE figure.

 

I have studied the Virgo Cluster that is the largest cluster in our vicinity. The core of this cluster is the giant elliptical M87 and a pair of ellipticals known as M84 and M86 that I have determined to be a 'binary'. The binary is orbiting M87 and the relative masses of M87 and the binary tells me that the CoG is between these two structures but much closer to M87 because its mass is much greater than the binaries.

The Hubble Constant could be the CoG at this point and given a single value that would apply to all the surrounding galaxies that are moving around this center,

Since I do not believe in the 'expansion of space', I would say that the redshift for this central region is approximately .00354 percentage wise.

This would give the HC a value of 63.5 kms/mpc/s at the current distance of 16.7mpcs. Shorten the distance and the HC increases.

This is the only question to resolve.
