Astronomers studying data from NASA’s Hubble Space Telescope have discovered that the universe is expanding at a rate of 9 percent faster than expected.
The experts used a new technique to study 70 special types of stars in the nearest galaxy of the Earth to measure distances across space and relied on this method to improve Hubble’s calculations, reflecting how rapidly the universe grew over time.
But the new results still contradict estimates of cosmic expansion based on the behavior of the universe.
The scientists, who took part in the latest study, say the result reduces the chance that this variation is just an accident, and suggests that new physics may be needed to better understand the universe.
Adam Ries, a professor of physics and astronomy at Johns Hopkins University, said the mismatch was growing and had now reached a point that was hardly a coincidence. “That’s not what we expected.”
