The universe is one of the things to which humans want to give greater explanation. For this reason, scientists and great minds have always formulated theories that help humanity understand how it works and solve the big question: Why? Such is the case of a theory that is turning everything that is known about our universe upside down and that of course, like all theories, is subject to what future observations can demonstrate.
This theory is that The Universe is not expanding due to dark energy, but rather it is expanding because it merges with “baby universes”.
Since the beginning of the Universe, scientists have seen that it is constantly expanding and little by little it has been demonstrated that the Universe is not stationary. But what is not yet well explained is what makes the universe expand. A very famous theory assumes that this is due to dark energy, but currently, a team of astrophysicists proposes that the Universe is expanding because it is in constant fusion with other universes called “baby universes.”
It may sound crazy to you, but… What new theory isn’t? As we mentioned at the beginning, this theory is subject to studies and new observations. This theory was published in the journal Journal of Cosmology and Astroparticle Physics and study co-author Jan Ambjørn, who is a physicist at the University of Copenhagen, explains: “The universe must be merging with the so-called “baby universes” to achieve expansion.” Furthermore, the expert points out that this theory fits better with the fact of what makes the Universe expand than the theory of the standard cosmological model.
Another co-author of the study and physicist at the Tokyo Institute of Technology (Japan), Yoshiyuki Watabiki, 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 decide which model best describes the current expansion of our Universe.”
“Baby universes”
The idea of baby universes was largely popularized by Stephen Hawking, which assumes that these universes would be the product of black holes, that is, each black hole that is created in our universe could give rise to a “baby universe.” and that they are only accessible to an observer who passes 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 of this on the study of our cosmos. However, researchers admit that this theory lacks observational evidence, but that it would not be for long, thanks to the immense number of experiments that currently exist and that are active right now, which study in detail the properties of the microwave background.
