Episode notes

The chapter delves into the concept of the Hubble constant and its relation to the expansion of the universe. It explains the significance of the Hubble parameter, its relationship with the energy density of the universe, and how it indicates an accelerating expansion model. The discussion covers the evolution of the Hubble parameter from the early universe to the present and its implications for the universe's expansion.

Welcome to the March 2024 Ask Me Anything episode of Mindscape! These monthly excursions are funded by Patreon supporters (who are also the ones asking the questions). We take questions asked by Patreons, whittle them down to a more manageable number -- based primarily on whether I have anything interesting to say about them, not whether the questions themselves are good -- and sometimes group them together if they are about a similar topic.

Big congrats this month to Ryan Funakoshi, winner of this year's Mindscape Big Picture Scholarship! And enormous, heartfelt thanks to everyone who contributed. We're going to keep doing this in years to come.
