Researchers Detect Smallest Force Ever Measured
2014-06-27 03:21:50

By Lynn Yarris, Berkeley Lab What is believed to be the smallest force ever measured has been detected by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley. Using a combination of lasers and a unique optical trapping system that provides a cloud of ultracold atoms, the researchers measured a force of approximately 42 yoctonewtons. A yoctonewton is one septillionth of a newton and there are approximately 3 x 1023...

Protecting Earth From Asteroids Using Stardust
2013-11-18 17:41:17

Lee Rannals for redOrbit.com – Your Universe Online A new research program is bringing experts together to help protect our planet from asteroids that could become catastrophes. The Stardust program is the first research-based training network of its kind, bringing together some of the world’s best experts on asteroids and space debris. An open training school is being held at the University of Strathclyde this week in the first step to train the next generation of scientists,...

Revealing New Information On Strength Of Black Hole Mergers
2013-11-08 07:13:10

Lee Rannals for redOrbit.com - Your Universe Online The Commonwealth Scientific and Industrial Research Organization (CSIRO) in eastern Australia has helped reveal new information about the strength of black hole mergers. Giant black holes throughout the universe sometimes pair up and merge, sending out gravitational waves that ripple across space and time. Albert Einstein predicted that these waves exist, but scientists have yet to directly detect one. Astronomers were able to...

One of the many counterintuitive and bizarre insights of quantum mechanics is that even in a vacuum—what many of us think of as an empty void—all is not completely still. Low levels of noise, known as quantum fluctuations, are always present. Always, that is, unless you can pull off a quantum trick. And that's just what a team led by researchers at the California Institute of Technology (Caltech) has done. The group has engineered a miniature silicon system...

Heart Of Space Mission LISA Pathfinder Successfully Tested, Ready For Launch
2013-06-05 14:13:03

Max Planck Institute for Gravitational Physics The optical bench of the LISA Pathfinder (LPF) mission passed with flying colors extensive testing at the Institute for Gravitational Research (IGR) at the University of Glasgow. IGR scientists assured that the high-precision measurement system is ready to survive tremendous forces up to 35 g (35 times the gravitational acceleration on Earth) during rocket launch. “With the successful tests we reached an important milestone. The...

Atom Optics To Predict Gravitational Waves
2012-10-19 08:33:13

[ Watch the Video: Atomic Interferometer To Predict Gravitational Waves ] April Flowers for redOrbit.com - Your Universe Online NASA is pursuing a pioneering technology capable of atomic-level precision to detect gravitational waves or ripples in space-time caused by cataclysmic events, including the Big Bang itself. Researchers at NASA's Goddard Space Flight Center, AOSense, Inc and Stanford University have been awarded funding under NASA's Innovative Advanced Concepts (NIAC)...

Microscale Optical Accelerometer Engineered By Researchers
2012-10-18 10:02:36

Imagine navigating through a grocery store with your cell phone. As you turn down the bread aisle, ads and coupons for hot dog buns and English muffins pop up on your screen. The electronics industry would like to make such personal navigators a reality, but, to do so, they need the next generation of microsensors. Thanks to an ultrasensitive accelerometer–a type of motion detector–developed by researchers at the California Institute of Technology (Caltech) and the University...

Looking Into The Heart Of A Supernova
2012-07-12 21:01:00

Caltech simulation points out how to detect a rapidly spinning stellar core Each century, about two massive stars in our own galaxy explode, producing magnificent supernovae. These stellar explosions send fundamental, uncharged particles called neutrinos streaming our way and generate ripples called gravitational waves in the fabric of space-time. Scientists are waiting for the neutrinos and gravitational waves from about 1000 supernovae that have already exploded at distant locations in...

Gravitational Waves Are The 'Sounds Of The Universe'
2011-10-03 09:19:36

Einstein wrote about them, and we're still looking for them -- gravitational waves, which are small ripples in the fabric of space-time, that many consider to be the sounds of our universe. Just as sound complements vision in our daily life, gravitational waves will complement our view of the universe taken by standard telescopes. Albert Einstein predicted gravitational waves in 1918. Today, almost 100 years later, advanced gravitational wave detectors are being constructed in the US,...

Squeezed Laser Will Bring Gravitational Waves To The Light Of Day
2011-09-12 06:34:03

  Measuring at the limits of the laws of nature — this is the challenge which researchers repeatedly take up in their search for gravitational waves. The interferometers they use here measure with such sensitivity that a particular quantum phenomenon of light — shot noise — limits the measuring accuracy. With the "squeezed light" method scientists from the Max Planck Society and the Leibniz University Hannover likewise use quantum physics in a countermove in order to...
