Black holes, those fearsome galactic traps from which not even light can escape, may not be quite so terminally destructive after all, according to physicist Stephen Hawking. The author of "A Brief History of Time" now believes some "information" sucked into black holes escapes over time, contradicting some of his most famous work on the phenomenon. Hawking will present his findings at a scientific conference in Ireland next week, New Scientist magazine said.

Round may be the preferred shape of baseballs, bubbles and Cocoa Puffs. The universe, however, may favor the ellipsoid. Italian scientists using data gathered by NASA's WMAP probe say evidence points to the universe having a shape somewhat akin to an egg, rather than the expected round kernel of puffed cereal. This, say the authors of a paper published this week in the scientific journal Physical Review Letters, would explain some curious anomalies over the heavens' expanse.

The birth and death of stars, the future of the universe, stellar explosions and the origin of life are among the topics to be discussed at a symposium on "The Origin and Evolution of the Universe" Friday at UCLA. Hosted by the Center for the Study of Evolution and the Origin of Life, leading astronomers and astrophysicists will discuss details of some recent developments in cosmology. The program is suited for a general-interest audience and will be held from 9 a.m. to 5 p.m.

A dark, unseen energy permeating space is pushing the universe apart just as Einstein predicted it could in 1917, according to striking new measurements of distant exploding stars by the orbiting Hubble Space Telescope. The energy, whose source remains unknown, was named the cosmological constant by Einstein. The new observations were led by Dr. Adam Riess at the Space Telescope Science Institute in Baltimore.

Creation: The Story of the Origin and Evolution of the Universe by Barry Parker (Plenum: $22.95; 289 pages) Wonder is the mother's milk of science. Why are things as they are? What is the truth behind the phenomena that we see? Can we explain the world around us, and if so, how can we do it? These are very difficult questions, both as a practical matter and philosophically.

An idea that Albert Einstein conceived and later repudiated as the biggest blunder of his life may actually have been correct. Recent astronomical observations and computer calculations suggest that the universe may truly contain a force represented by the "cosmological constant" Einstein proposed in 1917, a study says. Einstein introduced the constant as a mathematical term in an equation that applied his general relativity theory to the universe. The idea got him out of a sticky problem.

It was 1985 when I got off the train in Nara at dusk and began walking down a resi dential street lined with walled-in houses and gardens. It was the second week of my visit to Japan and I had just come from the fabled city of Kyoto, about half an hour away, where I spent the day wandering through temple grounds. Lost in thoughts about the day, I walked for several blocks in Nara before realizing I had not gone down the street leading to my minsuku , or inn. It was getting dark.

Want to discover the next big breakthrough in cosmology? Turn to the dark side, says renowned theoretical physicist Stephen Hawking. “The missing link in cosmology is the nature of dark matter and dark energy,” Hawking said Tuesday night at Caltech, where he lectured on the origin of the universe. Results from the European Space Agency's Planck space telescope shows “that normal matter is only 5% of the energy density of the known universe; 27% is dark matter, 68% is dark energy,” he said.
