Is our universe swallowing 'baby universes'?

Simulating the concept of multiverse

Every existing cosmological theory agrees that our universe is expanding at an ever-faster rate. Yet this phenomenon remains a huge mystery, and not all scientists agree that dark energy is the cause.

In a report published in the Journal of Cosmology and Astroparticle Physics , a team of researchers from the University of Copenhagen (Denmark) and the Tokyo Institute of Technology (Japan) proposed a new hypothesis to explain the above phenomenon.

Accordingly, they argue that our universe is simply swallowing up parallel "daughter universes", and thus is constantly expanding.

"Our discovery of the accelerating expansion of the universe may have a simple and intuitive explanation: our universe is just absorbing baby universes," explains report author Jan Ambjørn, a physicist at the University of Copenhagen.

While the idea of ​​other universes interacting with our own is not new, the research led by Ambjørn developed a mathematical model to investigate the hypothetical impact this would have on the evolution of our universe.

The calculations show that merging with other universes could increase the volume of our universe, which, based on current measurements, appears to be expanding faster.
