AI Thread Summary
Hubble's constant, approximately 70 km/s/Mpc, describes the rate of expansion of the universe, indicating how fast galaxies are moving away from each other. This expansion is linked to cosmic inflation, which suggests that the universe underwent rapid expansion shortly after the Big Bang, affecting the observable horizon. The Hubble horizon represents the maximum distance from which light has had time to reach an observer since the beginning of the universe, influenced by the rate of expansion. Understanding these concepts helps clarify how the universe's expansion impacts what we can observe. The relationship between Hubble's constant and cosmic inflation is crucial for grasping the dynamics of the universe's growth and its observable limits.

Ok I'm kinda confused of what is the relationship between hubble's constant, hubble's horizon length and how all those calculation works. I'm reading a textbook called quarks, leptons and the big bang but they don't explain it clearly, maybe I'm just slow but could anyone explain to me thnx!

Hubble constant is 70 km/s / Mpc.

Take the speed of light divided by 70 km/s and multiply by 1 Mpc.
 
hmmm ok maybe I wasn't clear of what I was trying to ask. I want to know how it relates to the inflation of the universe and the how the horizon is being affected during this major expansion. I don't want any calculation I just want to know the concept, but thanks for the Hubble constant calculation!
 
https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.
The formal paper is here. The Rutgers University news has published a story about an image being closely examined at their New Brunswick campus. Here is an excerpt: Computer modeling of the gravitational lens by Keeton and Eid showed that the four visible foreground galaxies causing the gravitational bending couldn’t explain the details of the five-image pattern. Only with the addition of a large, invisible mass, in this case, a dark matter halo, could the model match the observations...
Hi, I’m pretty new to cosmology and I’m trying to get my head around the Big Bang and the potential infinite extent of the universe as a whole. There’s lots of misleading info out there but this forum and a few others have helped me and I just wanted to check I have the right idea. The Big Bang was the creation of space and time. At this instant t=0 space was infinite in size but the scale factor was zero. I’m picturing it (hopefully correctly) like an excel spreadsheet with infinite...
