Proximity of early galaxies to each other

In summary, in the conversation, it is discussed that due to the expansion of the universe, galaxies are accelerating away from each other. This leads to the assumption that in the "older" universe, galaxies in the Hubble deep field at a distance of 12 or 13B light years would be much closer to each other. However, studies using 2df quasar data show that the density of quasars remains fairly stable over time, with the greatest density occurring around 2-3 billion years after the Big Bang. This evidence contradicts the steady state theory and supports the Big Bang theory.

Given that the universe is expanding and galaxies in general are accelerating away from each other, I would assume that galaxies appearing in the Hubble deep field at a distance of 12 or 13B light years from us should be much closer to each other than is typical for galaxies today. Is this a correct assumption, that this "older" universe we view is much more crowded?

Yes.

The problem with deep sky studies is only freakishly bright objects are detectable at great distances. Using 2df quasar data, density [of quasars] is fairly stable over time. The greatest density actually occur around 2-3 billion years after the BB. This is not shocking. It takes time for things like quasars to form. This little hump puts a big hurt on steady state theory, as does CMB, primordial elemental abundance, and other solid observational evidence.

Related to Proximity of early galaxies to each other

What is the proximity of early galaxies to each other?

The proximity of early galaxies refers to how close they were to each other in the early stages of the universe. This is a key factor in understanding the evolution and formation of galaxies.

How is the proximity of early galaxies determined?

The proximity of early galaxies is determined through various methods such as spectroscopy, which measures the redshift of galaxies to determine their distance from each other, and gravitational lensing, which can provide information about the distribution of matter and galaxies in a particular region.

Why is the proximity of early galaxies important in understanding the universe?

The proximity of early galaxies is important because it gives insight into the initial conditions of the universe and how galaxies formed and evolved over time. It also helps us understand the distribution of matter and the large-scale structure of the universe.

How has the proximity of early galaxies changed over time?

The proximity of early galaxies has changed over time due to the expansion of the universe. As the universe expands, galaxies move farther away from each other, making their proximity in the early stages of the universe much closer than it is now.

What can the study of the proximity of early galaxies tell us about the future of the universe?

Studying the proximity of early galaxies can give us insight into the future of the universe, as it helps us understand the rate of expansion and the distribution of matter. This information can help us make predictions about the fate of the universe and its eventual end.
