The Dark Energy Spectroscopic Instrument (DESI) is studying dark energy and the accelerated expansion of the universe.

New results from Dark Energy Spectroscopic Instrument hint that the influence of mysterious force driving universe's accelerating expansion may change over time.

For decades, astronomers have relied on Einstein’s theory of relativity to explain the expansion of the universe, assuming ...

New data further challenge the best scientific theory of the history and the structure of the universe. But a separate recent ...

A new map of cosmic expansion suggests that dark energy evolves over time, hinting that the universe doesn’t work the way we ...

New data involving millions of galaxies and luminous galactic cores is providing fresh evidence that the enigmatic and ...

Just because a mine has been exhausted of its ore, that doesn't necessarily mean it has no value. A 2023 study suggests that the shafts of such abandoned mines could serve as energy-storing gravity ...

Looks like we’re closer than ever to connecting general relativity and quantum mechanics. A new study suggests that when we ...

Physics has a problem—their key models of quantum theory and the theory of relativity do not fit together. Now, Dr. Wolfgang Wieland from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) is ...

Rotating black holes are the most powerful phenomenon in the known universe. Their powerful gravity radically alters the curvature of spacetime around them, leading to relativistic effects like time ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding ...

As a result, the light traveling across the cosmos could carry a memory of past gravitational-wave events imprinted in its properties. Related: 'Einstein's equations need to be refined': Tweaks to ...
