The universe is younger and We are now working on new physics as a result.
Adam Riess, Nobel Prize winning scientist, found that the universe is expanding 9% faster than previous calculations that were based on studying the aftermath of the Big Bang.
The study by Riess, an astronomer at Johns Hopkins University, which was published in Astrophysical Journal this week, and NASA's Hubble Space Telescope to calculate the new expansion rate, which scientists have theorized for years.
But Reiss, and other scientists, think that the expansion rates have increased, and they say the "new physics" may be necessary to explain the discrepancy ,
Reiss said that the universe "is outpacing all our expectations in its expansion, and that is very puzzling."

NASA astrophysicist John Mather, who has won a Nobel Prize, said the two different expansion rates could be down to two things, The Associated Press reported: "1
But Reiss downplayed the idea that the results could be the result of human error. He said that the mismatch between the two rates has been a point that is really impossible to dismiss as a fluke, he said. "This is not what we expect."
Riess said: "This is not just two experiments disagreeing."
The other is a prediction based on the Physics of the Early Universe and on the Physics of the Early Universe, the two eras.

"It looks and more like this," he said.
University of Chicago astrophysicist Wendy Freedman thus said that both calculations seem valid, and that "nobody can find anything wrong at this point" with either of the studies or their results.
Using measurements captured though the Hubble telescope, Riess thus 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.
