Galaxies, quasars, and stars… oh my! Dark Energy Spectroscopic Instrument (DESI) first data is a small fraction of the huge cosmic survey it will conduct.

Scientists propose a modified cosmological model that challenges the existence of dark matter and dark energy.
Many physicists are still skeptical that dark energy can fully explain gravity, and are therefore exploring alternative theories.
A new study evaluates gravity using string theory, a promising candidate for describing particle interactions at their most fundamental level.
Astronomers looking at how black holes grow over time may have found the answer to one of the biggest problems in cosmology.
A modification to the theory of general relativity makes it consistent with observable astronomical data without the need for dark energy.
Dark matter could be aggregating around black holes, providing a possible means of indirectly measuring its properties.
Researchers at the Southern University of Science and Technology in China ask if gravitons can be promising candidates for dark matter components.
The LUX-ZEPLIN detector is now operational and ready to capture weakly interacting particles believed to be the constituents of dark matter.
A new theory for the origin and nature of dark matter resolves some inconsistencies between cosmological predictions and astronomical data.
