Echoes discovered from Big Bang's expansion

Astronomers announced they have discovered cosmic ripples that are echoes of the massive expansion of the universe that took place just after the Big Bang.

The gravitational waves could help astro- and theoretical physicists better understand how the universe began and evolved into its present state.

Ulf Danielsson, a professor of theoretical physics at Uppsala University, called the discovery one of the biggest in the past several decades.

"If everything is confirmed I think (the discovery) is on par with the discovery of the Higgs Boson," Danielsson said.

He said the radiation, that astronomers observed and studied using data collected by a telescope in Antarctica, came from a time when the universe was just a few 100,000 years old.

On whether the discovery is worthy of a Nobel Prize this year, Ulf Danielsson told Radio Sweden:"I think that it is too early this year, this is something that has to be confirmed and discussed."
