H in cosmology

WebbThe scale factor, a ( t), is a term in Cosmology that in layman's terms represents the expansion rate of the universe. The question, therefore, is asking why the expansion of the universe is not written as being linear with respect to time. There are a few reasons why a ( t) ≠ t. First (and if you ask a mathematician, most importantly), we ...

Note − This is not a constant since the scale factor is a function of time. Hence it is called the Hubble’s parameter and not the Hubble’s constant. Thus, from this equation, we can infer that since D is increasing and V is a constant, then H reduces with the time and ... Webb5 apr. 2024 · Introduction.
