Calculations conducted by researchers in this matter show that the supposed merger with other universes increases the size of our own universe, which our instruments can detect as universe expansion. The scientists also calculated the expansion rate of the universe based on their new mathematical model, and found that their model fits the theory of multiverse mergers much better than the standard cosmological model. (According to the standard cosmological model, since only two of the four interactions, gravity and electromagnetism, are long-range, but objects are neutral due to both types of electric charge, the “face” of the universe is shaped only by gravity, which general relativity treats as a consequence of the curvature of spacetime.) The authors' theory addresses Also the problem of cosmic inflation – the mysterious ultra-rapid expansion that occurred in the first moments of the universe.
How is our universe evolving according to the new paradigm?
Theoretical physicists previously believed that this expansion, known as “inflation,” was caused by a virtual field that produced an extremely rapid expansion rate in the first milliseconds after the Big Bang. But in the new study, the authors suggest that this ultra-rapid early expansion may have been caused by…
That our young universe, just born, has been swallowed up by a larger universe.
“The fact that the universe… expanded in a very short period of time suggests that this expansion was caused by a collision with a larger universe, which means that it was our universe that was sucked into another emerging universe,” the researchers wrote. In their statement…

“Since we currently do not have a detailed description of the absorption process, it is difficult to judge whether such a scenario can be realized in a way that actually solves the problem with inflation (the expansion of the universe, Mr. Dr.) problems, but the interesting thing about such a scenario is that it does not require an inflation field,” the study authors hypothesize
That our universe, which inflated due to absorption with another universe at its origin, later collided with other universes,
Which therefore consists of several universes in its current state. Although the authors' theory makes it possible to solve some important problems in modern cosmology, only observational data can prove their hypothesis. Currently, many experiments are being conducted on microwave background radiation (remnants of the Big Bang, Mr. Dr.) to study its properties, so that scientists can obtain answers to these basic questions in the near future.
