A recent study could transform our understanding of the universe. According to data from the DESI project, dark energy, responsible for its rapid expansion, may be in decline. This observation suggests a different end for the universe, not through tearing apart or extreme cooling, but through collapse.
L’dark energy, this enigmatic component of the universe which accelerates its expansion, is at the heart of contemporary cosmological research. Major projects like the Vera C. Rubin Observatory with the world’s largest digital camera, and the Euclid space telescope peer into the far reaches of space to unlock the secrets energy and black matter. These initiatives aim to answer some of the most complex questions about the structure and future of the universe.
The Dark Energy Spectroscopic Instrument (DESI) is a major project that uses thousands of robotic eyes to collect and analyze light from millions of galaxies. According to his first observations, dark energy would not be a universal constant but would evolve over time. This discovery could not only contradict the scenario of a “Great Rending” or a “Great Cooling” predicted so far.

This new study questions the infinite expansion of the Universe
Traditionally perceived as a constant force, dark energy according to the LCDM (Lambda Cold Dark Matter) model seems to present variations which call into question its role in the expansion of the Universe. Luz Ángela García Peñaloza, eminent cosmologist, underlines the importance of this potential evolution which could mark the start of a new era in cosmological study.
If these variations are confirmed, they could signal that dark energy, far from being a static element, would be more dynamic and complex than expected. This could imply that the universe could ultimately experience a “Great Collapse” where he would withdraw into himself. This conclusion thus defies current predictions of a eternal expansion.
These discoveries could transform our understanding of the cosmos. They open the way to new theories about the fluctuating nature of dark energy and challenge predictions about the ultimate end of the Universe. Future results from DESI, combined with those from Euclid, are eagerly awaited to shed further light on these mysteries.
In the meantime, don’t panic! If the universe decides to collapse on itself, it would still need billions of years to achieve this.
