Astronomers found a new way to measure the 'stuff' of the Universe and the amounts match what Planck and others found.

Abdullah and a team of scientists did just that. They used another method, called the Cluster Mass-Richness Relation. It essentially measures the number of galaxy members in a cluster to determine the mass of the cluster. According to astronomer and team member Gillian Wilson, it offers a way to measure cosmic matter.

It’s not an easy method because it’s difficult to measure the mass of any galaxy cluster accurately. Much of the mass of the cluster is dark matter. In other words, what you see in a cluster isn’t necessarily all you get. So, the team had to get clever. They used the fact that the more massive clusters contain more galaxies than less massive ones. Since all the galaxies have bright stars in them, the number of galaxies contained in each cluster is used to estimate total mass.

Simulations were critical to this work, as well. Observations from the Sloan Digital Sky Survey allowed the team to assemble a catalog of galaxy clusters called “GalWeight.” Then they compared the clusters in the catalog with their simulations. The result was a calculation of the total matter in the universe based on the Mass-richness Relation.
