Hubble Expansion of the Universe

After studying data from NASA’s Hubble Space Telescope, Johns Hopkins University astronomer Adam Riess concluded that our universe is much younger and growing faster that we thought, or around 9 percent higher than previously stated. “It’s looking more and more like we’re going to need something new to explain this. Hey, it’s good news. Everybody likes to look younger,” said Riess, who also won the 2011 Nobel Prize in physics. Read more for another video and additional information.



“To come up with his measurement of the Hubble constant, Riess looked to some not-so-distant stars. It took about two years for the Hubble telescope to make these measurements, but eventually Riess calculated an expansion rate of 74. Using that 74 figure means the universe is somewhere between 12.5 billion and 13 billion years old. That’s much younger than the established estimates of 13.6 billion to 13.8 billion,” reports The Daily Star.
