Faint radio signals from the early Universe, soon detectable by Moon missions, may reveal how dark matter shaped gas cooling and clumping in the cosmic Dark Ages. Ordinary matter, which makes up the ...

If he can do that, it could lead to a fundamental shift in how we think about the universe and could even explain the presence of dark matter and dark energy. Vopson, PhD, studies information theory ...

Galaxies are far more than the sum of their stars. Long before stars even formed, dark matter clumped up and drew regular matter together with its gravity, providing the invisible scaffolding upon ...

Cosmological simulations of dark matter halos form the backbone of our understanding of large-scale structure in the Universe. By numerically evolving millions to billions of particles under gravity, ...

Dark energy is responsible for the expansion of the Universe, but its true nature is still a subject of much debate. Computer simulations based on the latest astronomical data enable scientists to ...

The Milky Way may be surrounded by dozens of yet-to-be-detected satellite galaxies, scientists claim. Using the highest-resolution simulation of our galaxy's dark matter — an invisible entity that ...

Physicists have unveiled a new way to simulate a mysterious form of dark matter that can collide with itself but not with normal matter. This self-interacting dark matter may trigger a dramatic ...

A cosmological simulation study by researchers from the Shanghai Astronomical Observatory of the Chinese Academy of Sciences has systematically revealed, for the first time, how the interaction ...

In this visualization, each dot represents a gas parcel with a mass approximately 1,000 times that of the Sun in the simulation of the cosmic Dark Ages. The left and right panels compare the cold and ...

This is interesting of course, but the article suffers from problems. Besides the missing article link, the linked spiral arm dynamical mass excess observations are not explained by dark matter as it ...
