Vol. 365, Issue 6458, pp. 1134-1138
DOI: 10.1126/science.aat7371The local expansion rate of the Universe is parametrized by the Hubble constant, H0, the ratio between recession velocity and distance. Different techniques lead to inconsistent estimates of H0.

The universe may be billions of years younger than we thought
New calculations point to an age of 11.4 billion years rather than the generally accepted number of 13.7 billion years.
Study finds the universe might be 2 billion years younger
The universe is looking younger every day, it seems.
New calculations suggest the universe could be a couple billion years younger than scientists now estimate and even younger than suggested by two other calculations published this year that trimmed hundreds of millions of years from the age of the cosmos.
The huge swings in scientists’ estimates — even this new calculation could be off by billions of years — reflect different approaches to the tricky problem of figuring the universe’s real age.
Scientists have known for decades that the universe is expanding, but research in the past few years has shaken up calculations on the speed of growth—raising tricky questions about theories of the cosmos.
