The Hubble constant may one day truly be constant
Original: The cosmic expansion rate changes with time, but we call it "the Hubble constant." If one specific condition is true, it
Physicists are highlighting a quirk in cosmology: the rate at which the universe expands changes over time, yet the parameter is called the Hubble constant. Big Think explains that if the universe keeps expanding as standard models predict, the expansion rate will eventually flatten into a true constant, but future observers would have no way of detecting that it ever changed.
Why now: The counterintuitive idea that a changing quantity could become an undetectable constant challenges assumptions about what science can observe.

- 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
