Dark energy may be the most mysterious substance ever proposed, but many scientists are certain it exists. Why?

The data analysed consists of 758 nights of observations of one-eighth of the sky conducted by the Dark Energy Survey (DES) ...

The Dark Energy Survey Collaboration collected information on hundreds of millions of galaxies across the universe using the ...

To explain these observations, they proposed a new kind of energy that is responsible for driving the universe’s accelerated expansion: dark energy. Astrophysicists now believe dark energy makes up ...

“As a result, for the past four decades, most researchers have believed that dark matter must be cold when it is born in the ...

Dark matter seems invisible, but it makes up most matter, and we have evidence that it gives the cosmos its shape. Now ...

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...

For a generation, cosmologists have treated dark energy as a fixed backdrop, a steady pressure stretching space faster and faster forever. Now a wave of new measurements suggests that this invisible ...

Physicists have unveiled a new way to simulate a mysterious form of dark matter that can collide with itself but not with ...

"Dark matter can be red hot when it is born, but still have time to cool down before galaxies begin to form." ...

In the search to understand how the universe came to be, a new theory is rewriting the script. Instead of one massive, fiery birth like the Big Bang, this idea suggests the cosmos has been growing in ...
