  1. Value of the Hubble parameter over time - Physics Stack Exchange

    Dec 15, 2011 · The physical interpretation of the Hubble time is that it gives the time for the Universe to run backwards to the Big Bang if the expansion rate (the Hubble "constant") were …

  2. Is there a relationship between the Cosmological constant and the ...

    Nov 16, 2015 · Since there currently exists uncertainty in precise evaluation of Hubble constant (known as the problem called "Hubble constant tension") - why there is no similar range …

  3. Is Hubble's constant really constant? - Physics Stack Exchange

    The behaviour in time of the hubble constant H yields whether the expansion speeds up of slows down. One can make models for the universe. The simpelest model is the Robertson-Walker …

  4. Units of Hubble Time and Hubble Constant? - Physics Stack …

    Sep 10, 2014 · The Hubble constant isn't actually constant and will change in the future. Exactly how it changes depends on the behaviour of dark energy, which is somewhat uncertain at the …

  5. Can the age of the universe actually be calculated through …

    Apr 20, 2023 · However, the Hubble constant was larger in the past, because objects, which in the past were at the unit distance from us, are now much further, and are moving (and were …

  6. cosmology - How is Hubble's constant (the expansion rate) …

    Feb 25, 2023 · How is Hubble's constant (the expansion rate) predicted from LCDM and the CMB? Ask Question Asked 2 years, 8 months ago Modified 10 months ago

  7. How does the Hubble parameter change with the age of the …

    Sep 18, 2014 · The graphs show that the Hubble constant is most definitely not constant, though it does tend to a constant value at late time. This is because the late time expansion is …

  8. astronomy - How is "little $h$" measured in cosmology? The ...

    Jul 28, 2015 · Hubble's law has been well-know for close to a century now. It is written as $v = H_0 d$ where the Hubble constant $H_0$ is the constant of proportionality between ...

  9. cosmology - Why is the reciprocal of the Hubble constant equal to …

    Jan 3, 2018 · The Hubble constant is the reciprocal of the age of the universe for any constant rate of expansion. But in the standard cosmological model the rate of expansion is not well …

  10. cosmology - Why is Hubble's constant exactly the inverse of the …

    Apr 23, 2017 · Why is Hubble's Constant exactly the inverse of the age of the universe? It isn’t; it’s just close to it. Your premise is false.
