The universe's contents include ordinary matter - stars, planets, gas, dust and all the familiar stuff on Earth - as well as dark matter and dark energy. Ordinary matter represents perhaps 5 per ...

The assumption of constant dark energy is baked into the widely accepted Lambda-CDM model of the universe. In this model, only 5% of the universe is made up of the ordinary matter we can see.

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 ... there due to what we call the quantum vacuum ...

So far, the preference for an evolving dark energy has not risen to "5 sigma," the gold standard in physics that represents the threshold for a discovery. However, different combinations of DESI ...

which is baked into the pie we call the standard model of cosmology or the Lambda Cold Dark Matter (LCDM) model. However, this model is built on the presumption that dark energy, represented by ...

The name dark energy was given to the phenomenon driving this acceleration, the effects of which seem to be partially offset by ordinary matter – and an also unknown thing called dark matter. The ...

The best theoretical fit thus far is known as the Lambda CDM model, which incorporates both a weakly interacting cold dark matter and dark energy. One alternative theory proposes that the Universe ...

"Really, Euclid is not only a dark universe detective, it's also a time machine. We will look back 10 billion years in cosmic history." The day that astronomers have been waiting for is here.

Cosmic Tug-of-War Around a century ago scientists began to realize that the universe is expanding outward from what they now call ... push of dark energy and the gravitational pull of matter ...

Taken alone, DESI’s data are consistent with our standard model of the universe: Lambda CDM (where CDM is cold dark matter and lambda represents the simplest case of dark energy, where it acts as a ...
