PITTSBURGH (KDKA) -- We have discussed gravity in a couple different experiments. This time, I am going to show you something that may seem almost impossible to do. Then we will discuss how it works, ...

For over a century, Einstein's general theory of relativity has been key to understanding gravity. But new research suggests this theory "glitches" in the farthest reaches of space. That doesn't mean ...

Recent research has sparked a captivating debate among physicists and philosophers alike: could gravity, the fundamental force that governs the universe, be nothing more than an illusion? This ...

The parabolic flight travels up and down several times on a trajectory resembling an arch, providing 22 seconds of zero ...

Leonardo da Vinci’s understanding of gravity, while not completely accurate, was “centuries ahead of his time”, according to a new study that reasessed sketches in the Italian polymath’s old notebooks ...

We probably think we know gravity pretty well. After all, we have more conscious experience with this fundamental force than with any of the others (electromagnetism and the weak and strong nuclear ...

Einstein’s general theory of relativity is a tool kit for solving problems involving gravity that connects mass and energy with deformations in spacetime. In turn, those spacetime deformations ...

To understand gravity, Einstein had to rethink space and time as a single connected fabric. He showed that mass bends this fabric, guiding how everything moves. NOVA is available to stream on pbs.org ...

The first use of a novel method of analyzing Mars' gravitational force supports the idea that the planet once had an extensive northern ocean. In doing so, the method defines the scope of what ...

Early on in science classes all over the world, students drop diverse things to learn how gravity works and how outside forces might affect the rate of fall. But the science of falling goes well ...

What if dark matter didn’t exist? Sure, scientists have never observed it, but they believe it exists because of apparent gravitational effects. But what if our current understanding of gravity was ...
