Universe expanding faster than expected says NASA
Hubble measurements hint a faster expansion rate in the modern universe than what was expected based on the study of how the universe showed 13 billion years back.
The universe is expanding considerably faster than it should, confirmed NASA. The Hubble Space Telescope of the space agency shows that it is growing about 9% faster than expected, based on how the universe appeared more than 13 billion years ago, according to the trajectory it began after the Big Bang, according to astronomers.
These measurements of the primitive universe come from the Planck satellite of the European Space Agency. This discrepancy has been identified in scientific articles in recent years, but it is not clear if differences in measurement techniques are to blame, or if the difference could be due to unfortunate measurements.
Such confirmation requires astronomers to find new theories to explain the strange behaviour of the universe. "This mismatch has been growing and has now reached a point that is really impossible to dismiss as a fluke," says a physics professor.
The latest Hubble data reduces the possibility that the discrepancy is just a chance of 1 in 100,000. This is a significant gain from a previous estimate, less than a year ago, of a possibility of 1 in 3,000.
These more accurate Hubble measurements to date reinforce the idea that new physicists may be needed to explain the mismatch.
"The Hubble tension between the early and late universe may be the most exciting development in cosmology in decades," said lead researcher and Nobel laureate Adam Riess of the Space Telescope Science Institute (STScI) and Johns Hopkins University, in Baltimore, Maryland. "This mismatch has been growing and has now reached a point that is really impossible to dismiss as a fluke. This disparity could not plausibly occur just by chance."
