Evidence is mounting that cosmic dark energy, long thought constant, may weaken with time - potentially altering the fate of ...

For generations, humans have gazed at the stars and wondered about the ultimate fate of the universe. Will it expand forever ...

"Dark matter could be captured by stars and accumulate inside them. If that happens, it might also interact with itself and ...

New evidence suggests the universe might not behave as expected, raising questions about the costs of being wrong.

The US Department of Energy-fabricated Dark Energy Camera at NSF’s NOIRLab’s Cerro Tololo Inter-American Observatory in Chile ...

Called the Dark Energy Spectroscopic Instrument (DESI), the collaboration released its first analysis of 6 million galaxies and quasars last year and has now added more data, bringing the count to ...

He's a member of the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX), is studying dark energy from an earlier time in the universe's existence than DESI.HETDEX is also focused on sound ...

Dark energy can be described as the effect of a negative pressure pushing space outward. We will get more technical, I promise, but let’s start with an analogy to understand this fundamental ...

New data suggests dark energy may evolve, challenging the belief that it's constant and forcing scientists to rethink ...

If dark energy changes over time, that gives astronomers entirely new theoretical frameworks to explore, from modified theories of gravity to energy fields that naturally evolve throughout cosmic ...

This dark energy bore all the earmarks of a fudge factor that Albert Einstein inserted into his theory of gravity back in 1917 to explain why the universe was not collapsing under its own weight.

If dark energy is weakening, as suggested by recent results, then the cosmos is far stranger than most physicists had supposed. Skip to main content. Scientific American. April 30, 2025.
