Probing The Dynamics Of The Crab Pulsar And Gravitational Waves

  • PDF
(June 3, 2008) — The search for gravitational waves has revealed new information about the core of one of the most famous objects in the sky: the Crab Pulsar in the Crab Nebula. An analysis by the international LIGO (Laser Interferometer Gravitational-Wave Observatory) Scientific Collaboration to be submitted to Astrophysical Journal Letters has shown that no more than 4 percent of the energy loss of the pulsar is caused by the...

Tapping The Early Universe For Secrets Of Fundamental Physics

  • PDF
(May 26, 2008) — The future of fundamental physics research lies in observing the early universe and developing models that explain the new data obtained. The availability of much higher resolution data from closer to the start of the universe is creating the potential for further significant theoretical breakthroughs and progress resolving some of the most difficult and intractable questions in physics. But this requires much...

Physicists Demonstrate How Information Can Escape From Black Holes

  • PDF
(May 15, 2008) — Physicists at Penn State have provided a mechanism by which information can be recovered from black holes, those regions of space where gravity is so strong that, according to Einstein's theory of general relativity, not even light can escape. The team's findings pave the way toward ending a decades-long debate sparked by renowned physicist Steven Hawking.

In the 1970s, Hawking showed that black holes evaporate...

Gravity Wave 'Smoking Gun' Fizzles: Gravitational Radiation Can Be Produced More Than One Way

  • PDF
(Apr. 17, 2008) — A team of researchers from Case Western Reserve University has found that gravitational radiation—widely expected to provide "smoking gun" proof for a theory of the early universe known as "inflation"—can be produced by another mechanism.

According to physics scholars, inflation theory proposes that the universe underwent a period of exponential expansion right after the big bang. A key prediction of inflation...

Searching For A Tiny New Dimension, Curled Up Like The Universe Before The Big Bang

  • PDF
(Mar. 12, 2008) — The universe as we currently know it is made up of three dimensions of space and one of time, but researchers in the Department of Physics and the Department of Electrical and Computer Engineering at Virginia Tech are exploring the possibility of an extra dimension.

Sound like an episode from the "Twilight Zone?" Almost, but not quite; according to John Simonetti, associate professor of physics in the College...

Stunt Doubles: Ultracold Atoms Could Replicate The Electron 'Jitterbug'

  • PDF
(Mar. 13, 2008) — Ultracold atoms moving through a carefully designed arrangement of laser beams will jiggle slightly as they go, two NIST scientists have predicted.* If observed, this never-before-seen "jitterbug" motion would shed light on a little-known oddity of quantum mechanics arising from Paul Dirac's 80-year-old theory of the electron.

Dirac's theory, which successfully married the principles of Einstein's relativity to...

Weaknesses In Structures -- From Massive Bridges To Nanotechnology -- Identified With New Gadget

  • PDF
(Mar. 8, 2008) — A patent has been awarded to Southeastern Louisiana University through one of its faculty that holds the potential to identify weaknesses in structures ranging from massive bridge construction to the tiniest elements of nanotechnology no larger than a speck of dust on a pinhead.

The patent is for a deformation prediction instrument developed by physicist Sanichiro Yoshida. The instrument uses the technology of...
