The regular matter that makes us, planets, stars, and galaxies is about 5 percent of the matter-energy content of the ...

As widely accepted as it is, dark matter has never been directly detected despite many experiments searching for it. Some scientists suggest that instead, we may need to adjust Newton’s law of ...

All this activity wouldn't affect the dark matter planet, since dark matter doesn't care what normal matter does with itself. But we might be able to see these explosions, giving away the presence ...

Dark matter is being thrown off the table with this new theory - simpler, and it relies on something that can be seen. Cosmic ...

Astronomers know dark matter exists because its gravity affects other things ... In the solar system, where most of the mass is within the sun at the center, the closest planet, Mercury, moves faster ...

One of those things ripe for interaction is our planet's atmosphere. And if a dark matter particle did interact with our atmosphere, this planetary shield would take away some of the particle's ...

Dark matter particles could be among the lightest in the universe, or they could have the mass of a dwarf planet, or anywhere in between. Dark matter could be “hot” or “cold,” which has ...

On this Halloween, let's delve into dark matter. ... And if it is and it doesn't interact with our planet, they could pass through one another. That'd be a really cool science fiction premise.

The surface of a planet within one parsec of the Milky Way’s center could reach over 5,700 kelvin, as hot as the sun’s surface, just from dark matter traffic.

Even when you budget in everything else that we've ever detected — neutrinos, light, even black holes — it leaves out 95% of all that must be out there: dark matter (27%) and dark energy (68%).

More massive planets in areas of high-density slow-moving dark matter, however, could capture enough dark matter to heat the planet enough to keep water in a liquid state on its surface.

Both events may follow our planet’s passage through dark matter concentrated in the Milky Way’s plane and help to trigger extinction events. Don Dixon for Astronomy.
