UChicago study: New LIGO readings could improve disputed measurement within 5-10 years
Twenty years ago, scientists were shocked to realize that our universe is not only expanding, but that it’s expanding faster over time. (more…)
EAST LANSING, Mich. — The key to successful global business expansion is spreading operations across multiple countries, rather than trying to dominate a region or market, according to a new study led by Michigan State University researchers.
In addition, since global expansion is costly for service industries, manufacturing industries will profit most, said Tomas Hult, director of MSU’s International Business Center.
Led by Hult and Ahmet Kirca, associate professor of marketing, the study is the largest ever conducted to examine the effect of multinationality on firm performance, Hult said. It incorporates data from nearly 48,000 firms. (more…)
PASADENA, Calif. — The faint, lumpy glow given off by the very first objects in the universe may have been detected with the best precision yet, using NASA’s Spitzer Space Telescope. These faint objects might be wildly massive stars or voracious black holes. They are too far away to be seen individually, but Spitzer has captured new, convincing evidence of what appears to be the collective pattern of their infrared light.
The observations help confirm the first objects were numerous in quantity and furiously burned cosmic fuel.
“These objects would have been tremendously bright,” said Alexander “Sasha” Kashlinsky of NASA’s Goddard Space Flight Center in Greenbelt, Md., lead author of a new paper appearing in The Astrophysical Journal. “We can’t yet directly rule out mysterious sources for this light that could be coming from our nearby universe, but it is now becoming increasingly likely that we are catching a glimpse of an ancient epoch. Spitzer is laying down a roadmap for NASA’s upcoming James Webb Telescope, which will tell us exactly what and where these first objects were.” (more…)
