Is the Universe Older Than We Think? Part 4: The Changing Lambda-scape Isn’t the FLRW metric way generic? It lays out the basic assumptions and tells us how the universe should behave, but it doesn’t say WHAT the universe is made of.

Is the Universe Older Than We Think? Part 2: Tired Light This is all based on the assumption that galaxies are receding away from us. And I actually cheated a little.

Is the Universe Older Than We Think? Part 1: The Cosmological Clock When I say that the universe is 13.77 billion years old, it sounds rather authoritative.

9/11 Time is the ultimate limiting factor. The universe has only existed for 13.8 billion years.

Even the earliest black holes had just a few hundred million years less than that to stuff themselves. There simply hasn't been enough time for infinite growth.

A chart illustrating the relationship between cosmological redshift (z), distance, time, and other cosmological parameters. The chart shows that redshift z=6 corresponds to a time when the universe was less than 1 billion years old, significantly younger than its current age of approximately 13.8 billion years. The chart includes scales for Hubble parameter (H), comoving radial distance (r_comov), angular diameter distance (dm), universe age, lookback time, angular size, and angular size per 1 kiloparsec.
