The discovery of dark energy. From 1999 to 2004, the cosmological community came together to agree that the universe was 5% ...

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 ...

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

Evidence that the universe is rotating was recently delivered by the James Webb Space Telescope (JWST), which found that ...

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 ...

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 ...

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

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 ...

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.

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.

We may already have had our first-ever encounter with dark matter, according to researchers who say a mysteriously high-energy particle detected in 2023 is not a neutrino after all, but something far ...
