There are two main types of screening models. The first is called the “chameleon” model. In this scenario, a hypothetical ...

(via Sabine Hossenfelder) Most astrophysics are pretty convinced that 80% of the matter in the universe is some invisible stuff that they can’t detect - dark matter. The idea has become more popular ...

A study of 300,000 galaxies confirms that gravity follows Newton's law and deepens the mystery of dark matter.

Gravity, as most people understand it, is the familiar force that pulls a falling apple toward Earth. But for astronomers and ...

Spiral galaxies rotate at such a high speed that the gravity calculated only from their visible stars could not prevent them from dispersing. To solve this puzzle, physicists have postulated the ...

About 85 percent of the matter in the universe is thought to be dark matter, yet there is still no confirmed direct detection of any dark matter particle. Ground-based detectors, space-based ...

Cosmic viewer The Atacama Cosmology Telescope in Chile was used by the team to observe gravitational interactions between ...

Gravity has shaped our cosmos. Its attractive influence turned tiny differences in the amount of matter present in the early universe into the sprawling strands of galaxies we see today. A new study ...

An international group of scientists, including Case Western Reserve University Astronomy Chair Stacy McGaugh, has published research contending that a rival idea to the popular dark matter hypothesis ...

How did the first galaxies after the Big Bang form and evolve? Were they small and attributed to dark matter or were they large and some other force attributed to their growth? This is what a recent ...
