Assistant Research Scientist Loredana Valenzano (Physics) and Co-PI Chair Ravindra Pandey (Physics) have received $4,481 from the University of California-Los Angeles for “First Principles Study of Primary Components of Portland Cement.”

Professor Raymond Shaw (Physics) and Co-PI graduate student Matthew Beals (Physics) have received $30,000 from NASA for a project, “Improved Mixed Phased Cloud Microstructure Measurements: The Holographic Detector for Clouds II (HOLODEC II).”

The Great Lakes Innovation & Technology Report, published by CBS Detroit, reported on the research of Robert Nemiroff (Physics) into gamma ray bursts, which is giving scientists a better understanding of the makeup of the universe.

Nemiroff’s discovery was also published in World Science and on Science Codex, an online science news site.

Spacetime: A Smoother Brew Than We Knew
Spacetime may be less like beer and more like sipping whiskey.

Or so an intergalactic photo finish would suggest.

Physicist Robert Nemiroff of Michigan Technological University reached this heady conclusion after studying the tracings of three photons of differing wavelengths that had been recorded by NASA’s Fermi Gamma-ray Space Telescope in May 2009.

Have three little photons broken theoretical physics?

“Originally we were looking for something else, but were struck when two of the highest energy photons from this detected gamma-ray burst appeared within a single millisecond,” Nemiroff told Life’s Little Mysteries. When the physicists looked at the data more closely, they found a third gamma ray photon within a millisecond of the other two.

Something’s wrong, Einstein’s right

To detect the ripples in space-time, scientists have turned to the radiation produced by incredibly violent cosmic events, known as Gamma Ray Bursts (GRBs). Produced by the death of giant spinning stars, GRBs are bright enough to be seen billions of light-years away – far enough to allow distortions due to Planck-scale effects to reveal themselves.

Several international teams have been examining records of GRBs for signs of the effects, pushing down to ever smaller scales. The most recent results have now been announced by a group led by Prof Robert Nemiroff of Michigan Technological University.

Quantum spacetime more like foam rubber than beer foam

A recent study of gamma-ray bursts by Professor Robert Nemiroff and his colleagues at Michigan Technological University provides the first strong evidence concerning the small-scale smoothness of spacetime. Oddly, this examination of the very small is accomplished by measuring a handful of gamma-rays after they traveled over ten billion light years.

Smooth Like Whiskey

These photons are so energetic, their wavelengths should make them small enough to interact with these little “bubbles” and be scattered. But because the photons arrived at the telescope in a dead heat, the MTU teams concludes they had nothing to interact with — that spacetime is not bubbly, but smooth (you know, like fine whiskey). Fantastic, how shall we celebrate?

It’s the Great Lakes Research Center, or GLRC. The public is invited to the dedication ceremony for Michigan Technological University’s newest building, set for 2 p.m., Thursday, Aug. 2. Inside are eight laboratories, each tailored for different research topics that relate to the Great Lakes, among them exotic and invasive species, fish ecology, sediments, remote sensing and atmospheric science. READ MORE
