Physicists question the name of the Hubble constant
Original: The cosmic expansion rate changes with time, but we call it "the Hubble constant." If one specific condition is true, it
A discussion is circulating in science circles about the Hubble constant, the measure of the universe's expansion rate. Critics point out that the expansion rate actually changes over time, so calling it a constant is misleading. One argument holds that if a specific cosmological condition holds, the rate will eventually settle into a true constant, though observers would never be able to confirm it.
Why now: The paradox of the misnamed 'constant' and its unobservable future value is intriguing to space and physics enthusiasts.

- The cosmic expansion rate changes with time, but we call it "the Hubble constant." If one specific condition is true, it will, one day, become a constant. But no one will be able to tell https:// bigthink.com/starts-with-a-ban… · HollyCo26588808@universeodon.com · 4
