New data from the Hubble Space Telescope confirm that the universe is expanding nine percent faster than theoretical calculations predicted.

Those original calculations were based on data from the early universe, so many scientists suspected that something accelerated the works. But the new Hubble data suggest that the universe could be substantially younger than previously believed, perhaps up to a billion years, according to The Associated Press.

"It looks like we're going to need something new to explain this," said Johns Hopkins University astronomer Adam Riess. The ap.

The original calculations suggested that the universe is between 13.6 and 13.8 billion years old. If the Riess hunch is correct, it would mean that it is only between 12.5 and 13 billion years old.

"Hey, that's good news," Reiss told the news agency. "Everyone likes to look younger."

Whodunnit

There is a possibility that the explanation of Riess is incorrect and something accelerated the acceleration of the universe at some point in the last twelve billion years. A possible culprit could be dark energy, but until now scientists have not been able to directly confirm that theory.

NASA astrophysicist John Mather said The ap that there are two possibilities: "1. We are making mistakes that we still can not find. 2. Nature has something that we can not yet find. "
