Understanding the nature of our universe and its future remains one of the most fascinating and complex questions in modern science. Despite technological advancements and enormous leaps forward in astronomical observation, experts still debate whether the universe is infinite or finite, its shape, and how it evolves over time.
In recent years, new research has been shedding light on these mysteries. The results are beginning to paint a picture far more dynamic and mysterious than previously thought, in which geometry, rotation, and the changing nature of dark energy may play a crucial role in the future of the cosmos.
What do we really know about the shape and structure of the universe?
To unravel this enigma, scientists worldwide have focused their efforts on analyzing data from the Cosmic Microwave Background (CMB) , a fundamental remnant of the Big Bang. While the local geometry of the observable universe appears to be flat or nearly flat , its global topology remains unresolved. An international group, known as the Collaboration for Observations, Models, and Predictions of Cosmic Anomalies and Topology (COMPACT), has reanalyzed this data, raising the possibility that the universe has a more complex structure than previously thought, including shapes like the cosmic torus or doughnut.
Their recent analyses suggest that, although definitive observational clues have not yet emerged, much remains to be done in the search for topological signatures that will help define whether space is truly infinite or, on the contrary, has a finite edge and shape.
Does the universe rotate? A hypothesis that challenges classical paradigms
Another revolutionary hypothesis in contemporary cosmology is the possibility that the universe rotates globally on its axis , like a cosmic spinning top. This idea, championed by physicist Nikodem Poplawski, has gained traction following observations from the James Webb Space Telescope, which show that many galaxy clusters exhibit a preferred rotation in the same direction.
If confirmed, this rotation could have decisive consequences for our understanding of dark energy. According to the proposed model, the centrifugal force associated with this global spin would influence the acceleration or deceleration of cosmic expansion, and could even be related to the existence of a multiverse, in which black holes would act as portals to new universes with their own rotation. Further studies on the asymmetry in galaxy rotation and the large-scale behavior of dark energy could shed definitive light on this intriguing theory.
The ultimate fate of the universe: new predictions under debate
Dark energy, that mysterious component that represents almost 70% of the universe's energy content, remains a focus of cosmology. An international team of astrophysicists has recently proposed, based on data from the Dark Energy Survey and the Dark Energy Spectroscopic Instrument, that the universe could stop expanding in about 7.000 billion years . The hypothesis suggests that dark energy would not be constant, but would gradually decrease, leading to a final contraction and collapse phase, the so-called Big Crunch.
This scenario proposes that the universe could behave like a rubber band : first expanding until it reaches a maximum limit, and then collapsing back on itself at an accelerated rate. Although it is a developing model subject to revision, the fact is that such a specific timeline for the possible end of the cosmos has never been proposed before, generating great excitement within the international scientific community.
Large telescopes and new windows to the early universe
The progress of cosmic observation is leading to spectacular advances . The Vera C. Rubin Observatory, inaugurated in Chile in 2025, promises to revolutionize the study of space and time thanks to the most powerful digital camera ever built. Through massive data collection and the use of artificial intelligence, it will allow the creation of a high-definition film about the evolution of the universe, bringing us closer to key answers about its origin and transformation.
Furthermore, recent observations from the Atacama Large Millimeter/submillimeter Array (ALMA) have allowed scientists to scrutinize the universe when it was just a billion years old. These detailed images of galaxies in the midst of formation have revealed unprecedented structures, chaotic motions, clustered star formation, and the existence of extended gas clouds, forcing a revision of traditional models of galaxy infancy.
The combined work of large telescopes, theoretical models, and advanced technologies is allowing scientists to get closer than ever before to solving the greatest mysteries of the cosmos , from its deep structure to the nature and evolution of dark energy.
