COPENHAGEN, Denmark – Astronomers from the University of Copenhagen have put forward a new theory for the accelerating expansion of our universe. While the expansion itself is widely acknowledged, the mechanics behind it have remained elusive. This theory suggests that the universe’s expansion may be driven by the merging of smaller, “baby” universes.
In the study published in the Journal of Cosmology and Astroparticle Physics, lead author Jan Ambjorn proposed that the accelerated expansion caused by dark energy may have a simpler explanation – the merging with other universes. This new model seeks to provide a better fit to observational data than the standard cosmological model.
The standard cosmological model, widely accepted in the scientific community, posits that the universe originated from the Big Bang and has been expanding ever since. However, this new study offers a mathematical model to demonstrate how merging with other universes could result in the expansion of our universe.
By quantifying the rate of expansion, the researchers’ calculations align more closely with observational data than the standard cosmological model. They also suggested that our young universe’s rapid expansion after the Big Bang may have been the result of a collision with a larger universe.
The implications of this proposed theory are significant, potentially redefining our understanding of the origins and expansion of the universe. While multiple universe theories are not new, this study provides a fresh perspective and a potential mathematical framework for understanding the processes that drive the evolution of our universe.
