The latest figures for baryonic mass etc.

The best guess numbers have hovered around 25 - 75 for the past few years:marcus said:now, if I understand the abstract, they want us to believe that Matter is only 23 percent. Maybe i am missing something. i will take more of a look.
they could be wrong, I guess. Maybe someone who follows this will comment.
I could have told you that! [http://www.kluweronline.com/oasis.htm/5092775 predicts a cold matter density of 22.2% (2/9)]marcus said:if I understand the abstract, they want us to believe that Matter is only 23 percent.
Start here:wolram said:By CHRONOS
This flat universe model is composed of 4.4% baryons, 22% dark matter and 73% dark energy

I think i read somewhere that if baryonic mass exceeded 4.4% by
a few percent, then the big bang model would be in trouble, if this
is so what is the max min baryonic matter allowable in the BB model
A galaxy red shift survey is a scientific study that involves measuring the red shift of galaxies in order to determine their distance from Earth. This information can then be used to map the structure and expansion of the universe.
A galaxy red shift survey is important because it helps scientists understand the large-scale structure of the universe, including the distribution and movement of galaxies. This information can also provide insights into the history and evolution of the universe.
Red shift is measured by observing the spectrum of light emitted from a galaxy. The wavelengths of the light will appear longer (or "shifted" towards the red end of the spectrum) if the galaxy is moving away from Earth. This is known as the Doppler effect.
The main tool used in a galaxy red shift survey is a spectrograph, which splits light into different wavelengths and allows scientists to measure the red shift of galaxies. Other instruments used may include telescopes and specialized cameras.
A galaxy red shift survey can provide information about the expansion rate of the universe, the distribution and movement of galaxies, and the effects of dark matter and dark energy. It can also help scientists test and refine theories about the origin and evolution of the universe.
