“Swarning in the laws of physics”: dark energy may not be what we thought

Three years of finally revealed cosmic data can forever change what we know about dark energy – which may be evolving in time after all.

The Dark Energy Spectroscopic Instrument (Desi), capable of capturing the light of 5000 galaxies at the same time, revealed that dark energy may not be the physical “cosmological constant” we thought-it may, after all, be modifying over time.

Desi collaboration adds more than 900 scientists from 70 institutions around the world, and the new discoveries were published on March 19 in which they are in the Arxiv online repository.

Researchers believe that dark energy can perform a Fundamental role in the accelerated expansion of the universe. Now it is known that this energy may be evolving.

Through measurements data from Cosmic Microwave Cosmic Radiation (CMB), A, and observations of weak supernoves and gravitational lenses, the team states that so far, the preference for an evolutionary dark energy has not yet reached a Statistical significance of 5 sigma.

“With a meaning of 4.2 sigma, I think we are coming to a point of no return,” one of the authors, Ishak-Bosshaki, told.

“In this new analysis, not only have we confirmed our previous discoveries that dark energy is probably evolving over time, as we are increasing its importance. The point that I consider most exciting is the fact that evidence from different data sets“He adds.

There are millions of data: the new analysis uses information from the first three years of observations of about 15 million galaxies and quasars.

“For 25 years I have been working with the issue of cosmic acceleration and my perspective is that if the tests continue to increase, and it is likely that is, this will be huge for cosmology and all physics,” says the researcher. Scitechdaily considers that the discovery can “Shake the laws of physics.”
