Measurements collected by NASA’s Hubble Space Telescope helped make the confirmation. It’s difficult to understand why. “The Hubble tension between the early and late universe may be the most exciting development in cosmology in decades,” said Adam Riess, distinguished professor of physics and astronomy at the Johns Hopkins University and Nobel laureate.The universe is constantly expanding as the space between galaxies grows. there is no explanation for the discrepancy, but new theories emerged. There’s something out there that we’ve missed.

“This is not what we expected,” said Riess, who won the Nobel Prize for physics in 2011 (along with Brian Schmidt and Saul Perlmutter) for showing, in the late 1990s, that the universe’s expansion is accelerating. Scientists have suggested scenarios involving invisible dark matter or dark energy. This mysterious form of energy is thought to constitute around 70 percent of the matter-energy density of the Universe. Possibly that dark matter is interacting more strongly with normal matter than astronomers have accounted for. The study was published  in The Astrophysical Journal.
