The Hubble Space Telescope has discovered a new milestone in the history of astronomy by observing how fast the universe expands.
However, according to the US National Aeronautics and Space Administration (NASA), the discovery contributed to an idea that ‘something strange is happening to the universe’.
Over the years, astronomers have used telescopes like Hubble to understand the speed of the expansion of the universe.
While these measurements were more accurate, one aspect attracted attention. There is a difference in the expansion rate of the universe compared to observations after the Big Bang.
However, scientists cannot explain this discrepancy. According to NASA, the difference suggests that this ‘some strange’ in the universe may be the result of unknown new physics.
For 30 years, Hubble has been collecting information from ‘markers’ in space that can be used to track the expansion rate of the universe as it moves away. According to the space agency, more than 40 markers have already been calibrated.
“You’re getting the most accurate measurement of the expansion rate of the universe from telescopes and the gold standard of cosmic mile markers,” says Nobel laureate Adam Rees of the Space Telescope Science Institute (STSCI) and Johns Hopkins University in Baltimore, Maryland.
He is the leader of a group of scientists that published a new paper describing in detail Hubble’s latest and greatest update.
