Of the four fundamental forces, gravity is the one we’re most familiar with in our everyday lives, but perhaps surprisingly, it’s the weakest and hardest to measure here on Earth. Now, physicists in ...

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...

Gravity is a force, which means that it pulls on things. But the Earth isn’t the only thing which has gravity. In fact, everything in the universe, big or little, has its own pull because of gravity – ...

Gravity is the reason things with mass or energy are attracted to each other. It is why apples fall toward the ground and planets orbit stars. Magnets attract some types of metals, but they can also ...

Antarctica sits above the strongest negative gravity anomaly on Earth, a region where the planet’s gravitational pull dips so ...

Forte and colleagues now believe Antarctica’s gravity hole was weaker before eventually intensifying around 30 to 50 million years ago. This corresponds to large-scale changes in the continent’s ...

What if the Milky Way’s central “black hole” isn’t a black hole at all? A new model proposes that an ultra-dense dark matter core could mimic its gravitational pull.
