Gravitational waves unmask universe just after Big Bang

For first time, researchers see traces of superfast cosmic expansion

Astronomers have detected the earliest echoes of the Big Bang, confirming a decades-old hypothesis that describes the universe’s ultrafast expansion during its first moments. The findings provide researchers with the first direct measurement of conditions at nearly the instant that cosmic expansion began, and may have far-reaching implications for physicists’ understanding of general relativity, quantum mechanics and the origin of the universe.

“We now have a much stronger belief that we under...
