Opportunity's Microscopic Imager found this intriguing object, looking more like Rotini pasta. Its odd shape has stirred up Mars researchers, both inside and outside of the NASA Mars Rover Exploration team. Whether or not this object is related to biology has prompted a variety of views.

] this is the bright new picture of black holes and their ] role in the evolution of the universe. Interviews with ] more than a half dozen experts presently involved in ] rewriting the slippery history of these elusive objects ] reveals black holes as galactic sculptors. ] ] In this revised view, which still contains some highly ] debated facts, fuzzy paragraphs and sketchy initial ] chapters, black holes are shown to be fundamental forces ] in the development and ultimate shapes of galaxies and ] the distribution of stars in them. The new history also ] shows that a black hole is almost surely a product of the ] galaxy in which it resides. Neither, it seems, does much ] without the other. ] ] The emerging theory has a nifty, Darwinist buzzword: ] co-evolution.

They now believe ] the figure is somewhere between 3.2 million and 4 million ] solar masses. ] ] And a new study suggests all that mass, confined to an ] area about 10 times smaller than Earth's orbit around the ] Sun, spins around about once every 11 minutes.

Phewww! That was a close one. I was only betting on 29 billion years. The new findings support Einstein's cosmological constant, which modern cosmologists say implies that dark energy should not characteristically change over time. If that's right, the universe will continue to expand at an accelerating forever. The new results suggest that even if Einstein and modern dark energy theory are both wrong, dark energy will not destroy the universe for at least 30 billion years, Riess and his colleagues say. "Right now we're about twice as confident than before that Einstein's cosmological constant is real, or at least dark energy does not appear to be changing fast enough, if at all, to cause an end to the universe anytime soon," Riess said. The universe is presently 13.7 billion years old. Universe Has At Least 30 Billion Years Left |
