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 ...

Computer simulations by astronomers support the idea that dark matter -- matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the ...

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, ...

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 ...

Computer simulations designed and run by researchers at the University of California-Irvine suggest that dark matter does in fact exist and is a central part of explaining how the universe works. The ...

With less than 20 percent of all physical matter made from visible stuff—from stars and planets, to the kitchen sink—astronomers continue to hypothesize what form the invisible majority of the ...

Physicist Melvin Vopson is trying to prove that information has a physical presence. If he can do that, it could lead to a fundamental shift in how we think about the universe and could even explain ...

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 ...

Astronomers have uncovered evidence that the Milky Way is not drifting through space alone but is embedded in a vast, flat structure of dark matter stretching tens of millions of light-years. The ...

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 ...

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 ...
