New, groundbreaking research shows that rotation curves of galaxies stay flat indefinitely, corroborating predictions of modified gravity theory as an alternative to dark matter In a breakthrough ...

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

With his theory of General Relativity in 1915, Albert Einstein revolutionized how we think about our universe. Rather than the cosmos simply providing the room for the planets and stars to orbit each ...

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

(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 ...

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 ...

Gravity behaves predictably in your daily life. Drop a ball, and it falls. Planets loop around stars. On paper, the same ...

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 ...

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 ...
