1 day ago · In 1998, scientists discovered that our universe expands with acceleration, and in order to explain this effect, the concept of dark matter was introduced. This is a special type of energy that ...

4 days ago · Physicists know dark matter exists because they can see its gravitational influence on galaxies, galaxy clusters and the overall evolution of the universe. Beyond that, there are few clues to work ...
5 days ago · Physicists have determined that there are at least six main cosmological parameters, one of which is the Hubble constant — a term that describes the universe’s rate of expansion. Other parameters describe density fluctuations in the primordial soup, immediately after the Big Bang, from which dark matter halos eventually form.
2 days ago · Dark Matter's Unseen Forces The researchers suggest that dark matter might behave similarly to ordinary particles that interact with each other, like billiard balls colliding. In contrast to the current model, where dark matter particles would pass through each other without interaction, this new study proposes that dark matter particles could ...
1 day ago · The model that’s currently primarily used is known as Λ Cold Dark Matter (ΛCDM) – DM that can only interact with itself and the rest of the universe via gravity. In today’s paper, the primary alternative to this model that’s being discussed is Self-Interacting Dark Matter (SIDM) – a model where, as the name suggests, DM particles ...
4 days ago · Dark matter doesn’t emit, absorb, or reflect light, making it invisible and detectable only through its gravitational effects. By analyzing how the light from these distant galaxies is bent and distorted, scientists can map the distribution of dark matter in the lensing cluster.
3 days ago · Black holes the size of an atom that contain the mass of an asteroid may fly through the inner solar system about once a decade, scientists say. Theoretically created just after the big bang ...
