Are there too many candles on the universe's birthday cake? New research shows scientists may have overestimated the age by more than a billion years.
Adam Riess, astrophysicist. Recently published findings that the universe is about a billion years younger than previously believed. Distinguished astronomer at the Space Telescope Science Institute (@stsci). Professor of astronomy and physics at Johns Hopkins University. He won the Nobel Prize in Physics in 2011.

"Using NASA's Hubble Space Telescope, Johns Hopkins University astronomer Adam Riess concluded in this week's Astrophysical Journal that the figure is 9% higher than the previous calculation, which was based on studying leftovers from the Big Bang.
"The trouble is, Riess and others think both calculations are correct.
"Confused? That's OK, so are the experts."
