Dark energy makes up roughly 70% of the universe, yet we know nothing about it. Around 25% of the universe is the equally mysterious dark matter, leaving just 5% for everything that we can see and ...

For decades, astronomers have treated dark matter as the invisible scaffolding of the cosmos, a mysterious substance that ...

New data further challenge the best scientific theory of the history and the structure of the universe. But a separate recent result reinforces it. Using the Dark Energy Spectroscopic Instrument, or ...

Astronomers have released the most ambitious cosmic map assembled so far, confirming that matter in the Universe is less ...

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 ...

Our current cosmological model—known as lambda cold dark matter, or ΛCDM—relies on hypothesized dark energy to explain the accelerating expansion of the universe. However, one competing theory known ...

Last spring, a team of nearly 1,000 cosmologists announced that dark energy — the enigmatic agent propelling the universe to swell in size at an ever-increasing rate — might be slackening. The ...
