Researchers synthesize molecular aggregates for solar energy applications
No molecule stands alone—they need others, at least when it comes to being able to display useful photophysical, electronic, and chemical properties. When individual molecules combine into an aggregate, or a complex of two or more molecules, they b.....»»
Professor proposes how a black hole in orbit around a planet could be a sign of an advanced civilization
In 1971, English mathematical physicist and Nobel-prize winner Roger Penrose proposed how energy could be extracted from a rotating black hole. He argued that this could be done by building a harness around the black hole's accretion disk, where infa.....»»
Could we ever harness quantum vacuum energy?
The fabric of spacetime is roiling with vibrating quantum fields, known as vacuum energy. It's right there, everywhere we look. But could we ever get anything out of it?.....»»
