Accelerating Universe Expansion: Age & Hubble Constant

[Mike holden]

TL;DR

How the age of the Universe depends on the rate of acceleration.

In my article - The accelerating expansion of the Universe at:
[Unacceptable reference delted by the Mentors]
I discuss how the age of the Universe depends on the rate of acceleration, the common factor being the value of the Hubble Constant at the present time. I go on to show how the expansion progresses in the future for each scenario.

age of the Universe depends on the rate of acceleration

The age of the universe is what it is. It doesn't get older because the rate changes, although the rate may change as it gets older.

The article makes fundamental assumptions that are not in accordance with the Lambda-CDM model. Assuming a simple power law is fine if you only have a single type of energy component in the Universe, but then the exponent will depend on the equation of state parameter of that component. In the current Universe, matter and the cosmological constant are of similar energy density and this means the simple power law is not a good description.

In addition, the estimate for the age of the Universe is based upon the cosmological model.
