You keep using that word. I do not think it means what you think it means. [0]

- danbruc 5y agoYou can also call it the Hubble parameter. But I think even then the current value of the Hubble parameter is still called the Hubble constant and it is still not constant. But don't worry, those are just labels, it doesn't really matter that a constant is not constant. We also didn't rename atoms once we realized we could rip electrons out of them or even smash them altogether. There is no tin in tin foil, no lead in pencil leads, no chalk in chalk sticks, and not all blackboards are black.
