Scientists find the footprint of the universe expansion after the Big Bang

This new discovery could confirm the theory of inflation, in which the universe expanded after the Big Bang

U.S. scientists have found a new evidence that supports the Big Bang theory , it is a signal in the form of a distinctive curve of light which the expansion left in space fractions of a second after it all started to happen.

“I’ve seen the research , the arguments are persuasive , and the scientists involved are among the most careful and conservative people I know ,” said Marc Kamionkowski , a researcher at Johns Hopkins University to the BBC chain.

This discovery was released by a group of scientists currently working in the project BICEP2 (Background Imaging of Cosmic Extragalactic Polarization), with the aid of a telescope located at the South Pole .

The objective of the research was to find a sign that there was a cosmic inflation , ie that the universe experienced exponential growth spurt in the first trillionth of a second .
