The universe is younger and is growing faster than expected, according to a new study. Scientists think we may have to work on a new physics.
A new study led by Nobel laureate scientist Adam Riess revealed that the universe was growing 9% faster than previous calculations based on the study of the consequences of the Big Bang.
The study of Riess, an astronomer at Johns Hopkins University, was published this week in Astrophysical Journal. It used new measurements from NASA's Hubble Space Telescope to calculate the new rate of expansion, theorized by scientists for years.
But Reiss and other scientists believe that the expansion rates achieved by both studies could be correct, which means that the rate of expansion of the universe has increased – and they claim that a "new physics" might be needed to explain the discrepancy.
Reiss said that the universe "exceeds all our expectations in its expansion, which is very confusing".

NASA astrophysicist John Mather, who also won a Nobel Prize, said the two different expansion rates could be reduced to two things, reported the Associated Press: "1. We make mistakes that we can not find 2. Nature has something we can not find yet. "
But Reiss downplayed the idea that the results could be the result of human error. He added that the "imbalance" between the two rates "has increased and has now reached a point that is really impossible to consider as a stroke of luck," he said. "That's not what we expected."
Riess said: "It's not just two experiences disagree."
"We measure something fundamentally different, one is a measure of the speed at which the universe is developing today, as we see it.The other is a prediction based on the physics of the first universe and measures of the speed at which it should develop If these values do not match, it becomes very likely that we are missing something in the cosmological model that connects the two epochs.

"It seems more and more that we will need something new to explain that," he said.
University of Chicago astrophysicist Wendy Freedman also said the two calculations seemed valid and that "nobody can find anything wrong at this point" with the studies or their results.
Using measurements captured with the help of the Hubble Telescope, Riess also calculated that the universe was between 12.5 billion and 13 billion years ago, less than previous estimates, between 13, 6 and 13.8 billion years.
