The universe is one of those things that mankind would like a greater explanation for, and for this reason, scientists and great minds have always formulated theories that help humanity understand how it works and solve the big question: Why? This is the case with a theory that turns everything known about our universe on its head, and is of course, like all theories, subject to what future observations can prove.

This theory is just that The universe is not expanding because of dark energy, it is expanding because it is merging with “small universes”.

Since the beginning of the universe, scientists have observed that it is constantly expanding, and little by little it turns out that the universe is not static. But what is not yet well explained is what makes the universe expand. There is a very popular theory that this is due to dark energy, but currently, a team of astrophysicists propose that the universe is expanding because it is constantly merging with other universes called “miniuniverses.”

It may seem crazy to you, but…what new theory isn't? As we mentioned at the beginning, this theory is subject to new studies and observations. This theory was published in the magazine Journal of Cosmology and Astroparticle Physics “The universe must merge with so-called ‘baby universes’ to achieve expansion,” explains study co-author Jan Ambjörn, a physicist at the University of Copenhagen. Moreover, the expert points out that this theory fits better with the truth of what makes the universe expand than the theory of the standard cosmological model.

Yoshiyuki Watabiki, another co-author of the study and a physicist at the Tokyo Institute of Technology (Japan), told Live Science:

“Our late expansion of the universe differs from standard cosmological predictions, and we believe that observations from the Euclid telescope and the James Webb telescope will define a model that best describes the current expansion of our universe.”

“Children's universes”

The idea of ​​small universes was greatly popularized by Stephen Hawking, who hypothesized that these universes would be the product of black holes, meaning that every black hole created in our universe could give rise to a “baby universe.” They can only be accessed by an observer passing through the event horizon of that black hole.

As you can see, it is not a new theory, what is new is the recent contribution of a mathematical model that allows us to explore the hypothetical impact this has on the study of our universe. However, the researchers admit that this theory lacks observational evidence, but that will not last long, thanks to the huge number of experiments that exist and are currently active, studying in detail the properties of the microwave background.
