The universe is younger and expanding faster than we thought, a new study found — and we may need new physics as a result

Universe
Scientists are working to calculate how fast the universe is expanding. BI
  • A new study led by a Nobel Prize winner found that the universe is younger and expanding faster than scientists thought.
  • Astronomer Adam Riess used measurements from NASA’s Hubble Space Telescope to conclude that the universe is expanding 9% faster than previous calculations said.
  • Reiss and other scientists think that both calculations could be right, which means that the rate of the universe’s expansion has increased
  • They think that “new physics” may be necessary to explain the difference.
  • Riess also calculated that the universe is between 12.5 billion and 13 billion years old — younger than the previous estimates of between 13.6 billion and 13.8 billion years old.

The universe is younger and expanding faster than we thought, a new study found, scientists think we may have to work on new physics as a result.

A new study lead by Nobel Prize-winning scientist, Adam Riess, found that the universe is expanding 9% faster than previous calcultions that were based on studying the aftermath of the Big Bang.

The study by Riess, an astronomer at Johns Hopkins University, was published in Astrophysical Journal this week, and used new measurements from NASA’s Hubble Space Telescope to calculate the new expansion rate, which scientist…
