The tug of gravity is gradually slowing down the general Hubble expansion of the cosmos. We don’t, however, have a good observational fix on the rate of this universal deceleration. In particular, we don’t know whether we’re slowing to an ultimate halt, to be followed by a recontraction to a “Big Crunch,” or whether the Hubble expansion will go on forever.
