Scientists Reveal Strange Reason They Believe We May Have Received A Signal From A Parallel Universe

A team of scientists now believe they may have found evidence that points to the possibility of a parallel universe existing alongside our own.

Back in 2019, researchers detected something unusual — a gravitational wave signal — and the discovery left experts puzzled. For those who aren’t familiar, gravitational waves are described by the Laser Interferometer Gravitational-Wave Observatory (LIGO) as 'ripples in space-time caused by some of the most violent and energetic processes in the Universe'.

This particular detection, named GW190521, was initially thought to have been produced by the collision of two black holes. But now, a group of researchers at the Chinese Academy of Sciences have put forward an entirely different possibility.

The scientists recently shared a paper titled 'Is GW190521 a gravitational wave echo of wormhole remnant from another universe?' which they submitted on September 9.

According to Futurism, the paper has not yet been peer-reviewed, meaning it is still awaiting further scrutiny from the wider scientific community.

As the title hints, the researchers are questioning whether GW190521 was really caused by merging black holes, or whether it could be evidence of something much stranger.

The team has put forward the idea that the wave signal might have actually traveled through a wormhole, originating from a parallel universe before reaching us.

In their paper, the researchers wrote: "A particularly compelling aspect of the GW190521 event detected by the LIGO-Virgo collaboration is that it has an extremely short duration, and lacks a clearly identifiable inspiral phase usually observed in the binary black holes (BBHs) coalescence."

"In this work, we hypothesize that GW190521 might represent a single, isolated gravitational wave (GW) echo pulse from the wormhole, which is the postmerger remnant of BBHs in another universe and connected to our universe through a throat [of a wormhole]."

To explain further, the 'throat' of a wormhole is the passage at the center, forming a tunnel that provides a shortcut between two different regions in space or even between universes.

The group at the Chinese Academy of Sciences acknowledged that the most straightforward explanation is still that the signal came from colliding black holes. However, they also pointed out that the current evidence is 'not significant enough to rule out the possibility that the echo-for-wormhole model is a viable hypothesis for the GW190521 event'.

The thought of us existing within a multiverse (and not the Marvel kind) has been debated in science for decades, with many researchers entertaining the idea that our universe may just be one bubble among countless others.

One of the leading voices supporting the idea of multiple universes is Alexander Vilenkin, a well-known author and theoretical physicist.

Vilenkin argues that the process of inflation, the rapid expansion of the universe after the Big Bang, didn’t end everywhere at the same time. Instead, he suggests that this cosmic inflation still continues in other parts of the cosmos, constantly creating new regions of space.

As Vilenkin explained to Scientific American back in 2011: "In our cosmic neighborhood, inflation ended 13.7 billion years ago, but it still continues in remote parts of the universe, and other 'normal' regions like ours are constantly being formed. The new regions appear as tiny, microscopic bubbles and immediately start to grow."

"The bubbles keep growing without bound; in the meantime, they are driven apart by the inflationary expansion, making room for more bubbles to form. This never-ending process is called eternal inflation."

"We live in one of the bubbles and can observe only a small part of it. No matter how fast we travel, we cannot catch up with the expanding boundaries of our bubble, so for all practical purposes we live in a self-contained bubble universe."
