Gravity Waves, Predicted By Einstein’s General Relativity Theory, May Soon Be Detected

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 when the latest, most sensitive experiments hunting gravitational waves come online. “There’s so much activity and excitement in the field right now,” said Mansi M. Kasliwal, an astronomer at the Observatories of the Carnegie Institution for Science in Pasadena, Calif. “The momentum is really building.”

Kasliwal is the author of a paper published online today (May 2) in the journal Science describing the burgeoning field of gravitational wave studies.

Star-Shaped Gravity Waves Discovered By Physicists In France

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 bob up and down in a manner directly proportional to the force that the weight exerts on the spring.

However, a number of strange waves can also form. They come from what is called nonlinearity, in which a small or simple change results in a disproportionately large or complex effect. For instance, aspects of weather behave chaotically, in a nonlinear manner.

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 disproportionately large or complex effect. For instance, aspects of weather behave chaotically, in a nonlinear manner.

Alt-week 12.29.12: the speed of gravity, disease-smelling dogs and catching asteroids

Click link below picture

.

2012, we salute you. All in all, you’ve been a pretty good year. There’s been highs, lows, and lots of inbetweens. Above all else, though, you’ve been generous in the alternative arena. Whether it’s the discovery of certain particles, or activities in space, 2012 had it covered. What better way to finish it off, then, with a disease smelling dog, a plan to catch an asteroid and a growable hangover cure. This is alt-week.
