Just a few hundred million years after the Big Bang, the universe was a dark and simple place. There were no galaxies like ...

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 ...

The most active galaxies always eventually stop producing stars, but astronomers struggled to understand why this phenomenon ...

An almost invisible galaxy could crack open one of the biggest questions in cosmology ...

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 ...

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, ...

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 ...

Dark matter, one of the Universe’s greatest mysteries, may have been born blazing hot instead of cold and sluggish as scientists long believed. New research shows that dark matter particles could have ...

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 ...
