In a major discovery, scientists say space-time churns like a choppy sea

The very fabric of the cosmos is constantly being roiled and rumpled all around us, according to multiple international teams of scientists that have independently found compelling evidence for long-theorized space-time waves.

The claim that telescopes across the planet have seen signs of a “gravitational wave background” has sent a thrill through the astrophysics community, which has been buzzing for days in anticipation of the papers that were unveiled late Wednesday. The discovery seems to affirm an astounding implication of Albert Einstein’s general theory of relativity that until now has been far too subtle to detect.

In Einstein’s reimagined universe, space is not serenely empty, and time does not march smoothly forward. Instead, the powerful gravitational interactions of massive objects — including supermassive black holes — regularly ripple the fabric of space and time. The picture that emerges is a universe that looks like a choppy sea, churned by violent events that happened over the course of the past 13 billion-plus years.

The gravitational wave background, as described by the astrophysicists, does not put any torque on everyday human existence. There is not a weight-loss discovery in here somewhere. A burble of gravitational waves cannot explain why some days you feel out of sorts. But it does offer potential insight into the physical reality we all inhabit.
