SpaceX launched the European Space Agency's $1.5 billion Euclid space telescope Saturday, an ambitious, first-of-a-kind attempt to pin down the nature of dark matter — an unknown material pervading ...

For a quarter century, cosmologists have treated dark energy as a fixed, featureless pressure that steadily drives galaxies apart. Now a convergence of massive sky surveys and giant computer models is ...

The instrument is called DESI, the Dark Energy Spectroscopic Instrument, and its job is dull in the way that all great experiments are dull. Measure the redshifts. Map the positions. Build the biggest ...

(Nanowerk News) A new study by MIT physicists proposes that a mysterious force known as early dark energy could solve two of the biggest puzzles in cosmology and fill in some major gaps in our ...

"This could be the most interesting discovery in cosmology since that of dark energy itself." When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The ...

It has been over two decades since the discovery of dark energy. Scientists have therefore had more than 20 years to decode the secrets of this invisible substance that appears to be pulling the ...

The largest 3D map of the universe ever created is providing hints about the evolution of the cosmos, and they suggest that we may be wrong about the behaviour of dark energy, which makes up most of ...

"If this is true, this just turns cosmology upside down." When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. It has been over two decades since the ...

Viscous cosmology explores the influence of internal frictional effects in the cosmic fluid on the large-scale dynamics of the universe. In this framework, bulk and shear viscosity act as dissipative ...

Scalar-tensor cosmology extends Einstein’s theory of gravitation by introducing a dynamical scalar field that mediates part of the gravitational interaction alongside the metric tensor. These models ...

As I finished my PhD in 1992, the universe was full of mystery – we didn’t even know exactly what it is made of. One could argue that cosmologists had made little progress in our understanding of ...
