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 …

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 …

Sep 10, 2014 · The Hubble time is then just the reciprocal thereof. In fact, I'd say to think of it as reciprocal time is more natural than to use speed per distance, because the real "gist" of the …

Feb 25, 2023 · How is Hubble's constant (the expansion rate) predicted from LCDM and the CMB? Ask Question Asked 2 years, 9 months ago Modified 22 days ago

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 …

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 …

Jan 6, 2025 · However, the Hubble constant has been decreasing since the Big Bang. While this decrease occurs, the general trend of objects receding faster with increasing distance (as …

10 The Hubble time is about 14 billion years. The estimated current age of the Universe is about 13.7 billion years. Is the reason these two time are so close (a) a coincidence, or (b) a …

Jul 28, 2015 · Do astronomers measure the Hubble constant (using Cepheid distances, Type Ia Supernovae, etc.) and then calculate $h$? Supposedly the value agreed upon today is around …

Equation for Hubble Value as a function of time Can space expand with unlimited speed?
