An international research collaboration has used advanced computer simulations to investigate how faint radio signals from the early universe, soon to be observed from missions on the far side of the ...

Dark matter is a difficult subject because, on the one hand, we don’t really know if it even exists at all. On the other hand, many models of the universe rely on it to work. So, when a theory comes ...

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 ...

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 ...

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 ...

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 ...

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 ...
