Scientists have a new hypothesis called “cosmical coupling,” which will potentially give more clues into how our mysterious world operates. The widely accepted theory about the origin of the universe is the Big Bang. It states that when the explosion occurred, the universe expanded outwards and is still doing so today. The new cosmical coupling hypothesis adds another element to this, arguing all objects with mass in the universe grow alongside it.

Researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo interferometer have been gaining data for this theory since 2015, through analyzing gravitational waves. Gravitational ripples in space can be seen when two huge black holes orbit each other, eventually spiraling inward and merging together. Previously, the size and strength of the gravitational forces have been impossible to explain.

The paper, published in The Astrophysical Journal Letters, showed if the expansion of the universe is aligned with expanding black holes, then these forces start to make sense. The group simulated millions of stars using AI. Two stars were modeled collapsing in on themselves at the end of their lives, transforming into black holes. The math behind their gravitational pulls was calculated and outputted using the computer code, and the cosmical coupling theory was tested against it. It turns out the data sets align extremely well!

“Planned upgrades to LIGO-Virgo, plus the data they will collect over the next decade, will describe many more black hole mergers,” says Kevin Croker, the first author of the paper. “The more data that is collected, the more powerfully we can test our hypothesis.”

Cosmical coupling would also be occurring and causing the expansion of everything in the universe according to this theory, including our own planet. The reason the hypothesis data is coming from black holes is due to their huge size and corresponding huge forces that are operating there. Currently, gravitational detection systems are not sensitive enough to pick up waves from smaller masses. For now, the math adds up, and with equipment becoming more sensitive, we will soon be able to see this phenomenon happen to all sorts of things around the universe.
