A new study reports conclusive evidence for the breakdown of standard gravity in the low acceleration limit from a verifiable analysis of the orbital motions of long-period, widely separated, binary ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth ...

Gravity is the force that keeps us grounded. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Gravity is one of the universe's fundamental forces ...

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 ...

Although we take a lot of scientific knowledge for granted today, each of the basics – whether it be about light, gravity, mass or the shape of the Earth – had to be theorized and experimentally ...

Einstein's theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. When you purchase through links on our site, we may earn ...

One of the most astonishing facts about science is how universally applicable the laws of nature are. Every particle obeys the same rules, experiences the same forces, and sees the same fundamental ...

While it would be awesome for people to be able to live in space, a "weightless" environment poses some serious challenges. Humans function best on Earth’s surface, where they are affected by a ...

In space, weightlessness is inconvenient, to say the least. Your tools float around. It's harder to eat. It's a chore to use the toilet. Not to mention, there's all those pesky health problems that ...

Remember that time you were upside down in a roller coaster and, for exactly one second, your body left contact with your seat? The moment of exhilaration that made waiting in the long queue for that ...
