A sweeping barred spiral galaxy marks the spot in this image, but the real treasure is the gravitational lens in the ...

Wide binary stars as direct probes of the nature of gravity at low acceleration weaker than about 1 nanometer per second squared have been hotly debated. The nature of gravity at such low acceleration ...

We now have the most precise estimates for the strength of gravity yet. Two experiments measuring the tiny gravitational attraction between objects in a lab have measured Newton’s gravitational ...

A falling cat under normal Earth conditions can twist its body toward the ground and prepare to land on its feet. When American researchers placed cats aboard specially modified aircraft producing ...

You see this all the time in textbooks: This is often described as "the acceleration due to gravity". Is this really the best thing to call this? No. A better name would be "the local gravitational ...

A trip to Mars may be more feasible than previously thought, suggests a new study led by Northwestern Medicine, UT ...

When you travel through the Universe, it isn't just a free ride through empty space. Although you might not think about it very often, there are forces arising from the presence of everything else, ...

Late in the 20th century, scientists discovered something amazing: gravity doesn’t just suck, it also blows. This knowledge comes to us by looking at distant supernovae and determining how fast they ...

Two black holes, each with accretion disks, are illustrated here just before they collide. The inspiral and merger of binary black holes provided humanity with our first direct measurement of ...
