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

What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

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

The universe seems to be spinning, and that could explain what dark energy is and why it's weakening while revealing our ...

Dark energy, the mysterious force thought to be driving the ever-faster expansion of the universe, appears to be changing over time, according to new observations released Wednesday.

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 is the placeholder name given to whatever aspect of the universe is causing the fabric of spacetime to inflate faster and faster, constantly pushing galaxies apart more rapidly.

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 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 constant, the universe will continue to expand, forever getting colder and emptier. If it's growing in strength, the universe will expand so speedily that it'll destroy itself in ...
