Image Gallery: Weird Gravity Waves

Star-studded (Image credit: Jean Rajchenbach, Alphonse Leroux, and Didier Clamond (CNRS and Université de Nice, France))Researchers have discovered a new type of gravity wave, one that is shaped like a star. Such bizarre waves result from a property called nonlinearity, in which a small or simple change results in a...

Bizarre Star-Shaped Gravity Waves Created

Star-shaped waves can form in vibrating tanks of liquid oil, researchers say. Learning more about such bizarre waves could shed light on counterparts that may exist elsewhere in nature, researchers added. Waves of all kinds often behave in an intuitively linear manner. For instance, a weight on a spring will...

Sex in Space: Plant Canoodling Is Weird Without Gravity

A real-time look at plant sex in an environment simulating microgravity reveals that agriculture in space might face challenges. The study also illuminates how gravity works on intercellular transport, a crucial process for mating plants and communicating human brain cells alike. There's no word yet, however, on how human sex...

Quantum Mechanics Trick May Detect Invisible Gravity Waves

The existence of gravitational waves, or ripples in space and time, has long been predicted, but the elusive phenomenon has eluded scientists for decades. Now researchers are proposing a new method to detect these cosmic wrinkles that relies on the quantum nature of atoms. Gravitational waves are a consequence of...

The Hunt for Elusive Gravity Waves Heats Up

In the next five years or so, scientists are poised to discover proof that space and time can wrinkle in the form of gravitational waves. These waves were predicted almost 100 years ago by Albert Einstein's general theory of relativity, but have yet to be seen. That could change soon...

Levitate Me: Water Droplets Dance, Defy Gravity (Video)

Wanna make a water droplet dance? Turns out all you need is a pair of opposing ultrasonic speakers. Called acoustic levitation, this technique holds droplets of water against gravity using ultrasonic waves. While this process has been done before, a team of scientists took the experiment a step further and...

What Gravitational Ripples from Big Bang Mean for Physics

The discovery of ripples in space-time from the mysterious earliest moments after the Big Bang is not only a smoking gun for the universe's rapid expansion but also could have important implications for physics. If the landmark finding of these gravitational waves, announced Monday (March 17), is confirmed, it would...

'Big G': Scientists Pin Down Elusive Gravitational Constant

A fundamental constant that sets the size of the gravitational force between all objects has finally been pinned down using the quirky quantum behavior of tiny atoms. The new results could help set the official value of the gravitational constant, and may even help scientists find evidence of extra space-time...

Einstein's Gravity Waves Could Be Found with New Method

Gravitational waves, invisible ripples in the fabric of space and time, might be detected by looking for the brightening of stars, researchers say. These mysterious ripples were first proposed by Albert Einstein as part of his theory of general relativity. The waves' size depends on the mass of the objects...
