A new model of the Universe suggests that modifying Newton's theory of gravity could do away with the need for dark matter. The model instead relies on an as-of-yet undiscovered form of gravity to ...

Astronomers have put together one of the most comprehensive maps of all the matter in the universe. The huge undertaking hints at a slightly smoother universe than we thought, suggesting that ...

Explore the debate surrounding a potential dark matter discovery, highlighting skepticism and the need for rigorous ...

A groundbreaking new study, recently published on arXiv, challenges one of the most fundamental assumptions in cosmology: that dark matter remains constant over time. For decades, scientists have ...

"The HYPER model of dark matter is able to cover almost the entire range that the new experiments make accessible," Elor said. Specifically, the research team first considered the maximum cross ...

One of the biggest mysteries in astrophysics today is that the forces in galaxies do not seem to add up. Galaxies rotate much faster than predicted by applying Newton’s law of gravity to their visible ...

Dark matter and dark energy—the mystery forces believed to govern the universe—may not exist after all. In a newly developed model, astronomer André Maeder has found that neither of these concepts is ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Ever since the early 20 th century, we’ve known that the universe ...

Dark matter is the elusive, invisible substance that appears to make up more than 80 percent of the total mass in the universe — far more than accounted for by the "regular" matter that makes up ...

Most of the small satellite galaxies orbiting the large galaxy Centaurus A rotate in the same direction in a well-defined plane. This coordinated motion is contrary to predictions made by the cold ...

For years, dark matter has been behaving badly. The term was first invoked nearly 80 years ago by the astronomer Fritz Zwicky, who realized that some unseen gravitational force was needed to stop ...

One of the biggest mysteries in astrophysics today is that the forces in galaxies do not seem to add up. Galaxies rotate much faster than predicted by applying Newton’s law of gravity to their visible ...
