Not everything we knew about the universe is wrong. But not not everything. The Dark Energy Spectroscopic Instrument (DESI) ...

Physicists have proposed a new model of space-time that may provide the 'first observational evidence supporting string ...

If dark energy is weakening, it stands to reason that eventually gravity will become dominant and the universe will begin to contract. In such a scenario, the universe would collapse back into a ...

The puzzle is related to dark energy’s equation of state, which describes the ratio of pressure of the universe to its energy density. In a universe with an accelerating expansion, the equation of ...

"The first box uses a Lambda CDM cosmology, while the second box contains a dark energy equation of state w, which evolves in time." The values of cosmological parameters are based on DESI's year ...

Dr. Richard Lieu, a physics professor at The University of Alabama in Huntsville (UAH), a part of The University of Alabama ...

Leading this quest is the Dark Energy Spectroscopic Instrument (DESI), a global collaboration involving over 70 institutions.

The research team found that the statistical significance of the dynamical dark energy model has reached a 4.3σ confidence ...
