Gravity Wave "Smoking Gun" Fizzles, According to Case Western Reserve Physics Researchers

Lawrence Krauss

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 theory is the presence of a particular spectrum of "gravitational radiation"—ripples in the fabric of space-time that are notoriously difficult to detect but believed to exist nonetheless.

"If we see a primordial gravitational wave background, we can no longer say for sure it is due to inflation," said Lawrence Krauss, the Ambrose Swasey Professor of Physics and Astronomy at Case Western Reserve. Read more.

Benefits, Challenges of Wind Energy Take Center Stage at Research ShowCASE

The world is addicted to electrical power, and the demand is increasing. Annual global generation of electrical energy was 16,424 billion kilowatt-hours in 2004; it's predicted to increase to 30,364 billion kilowatt-hours by 2030.

The increase in oil prices, along with the desire to balance the need for increasing demands without ruining the environment, is just one of the topics that will be discussed during the "Wind Energy: A Resource for the Future?" forum beginning at 12:30 p.m., April 17 at Case Western Reserve University's Sixth Annual Research ShowCASE.
