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 ...

CHRISTCHURCH, New Zealand — Dark energy has been modern physics’ most successful placeholder, a theoretical force invented to explain why galaxies seem to be racing away from each other at ...

The accelerating expansion of the Universe may not be real, but could just be an apparent effect, according to new research published in the journal Monthly Notices of the Royal Astronomical Society.

Scientists studied the magnetic fields of a five billion light-years away galaxy. In this picture: Scientists detected X-rays coming from a type Ia supernova for the first time. Digital Sky ...

Cosmologists have long wondered whether dark energy and the accelerating expansion of the universe is an illusion. Now the evidence backing this idea is mounting. Back in 1998, astronomers made a ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you purchase ...

A looming mystery lies at the heart of modern cosmology, and it has everything to do with the ever-accelerating expansion of the universe. First discovered in 1998 by analyzing distant Type 1a ...

The accelerating expansion of the Universe may not be real, but could just be an apparent effect, according to new research. The new study finds the fit of Type Ia supernovae to a model universe with ...
