A relativistic examination of gravity in the galaxy may indicate that the invention of dark matter may not be necessary to solve the not-enough-matter problem. “The motions of stars in galaxies is realized in general relativity’s equations without the need to invoke massive halos of exotic ‘dark matter’ that nobody can explain by current physics.”
Update: mjt has doubts about the paper referenced here and notes that there’s other evidence for dark matter that is not questioned by the above study.
Google and NASA have announced plans to collaborate on projects like “large-scale data management, massively distributed computing, bio-info-nano convergence, and encouragement of the entrepreneurial space industry”. In 6 months, Yahoo will announce a collaboration with the Russian Space Agency to launch original content into space. Microsoft will announce in a year that they’ve had space travel capabilities built into Office for years now but no one uses it…in two years time, they’ll completely reorg around manned missions to Mars.
Is PowerPoint responsible for the woes of the Space Shuttle? Well, no, but it’s not helping any. “The deeper problem with the PowerPointing of America — the PowerPointing of the planet, actually — is that the program tends to flatten the most complex, subtle, even beautiful, ideas into tedious, bullet-pointed bureaucratese.”
Fantastic must-read article slamming NASA with regard to the Space Shuttle program. I’ve been following Maciej’s del.icio.us links about the Shuttle for weeks now and was wondering if he’d get around to writing it up. Worth the wait.
The Space Shuttle is set to return to space today. Looks like you can watch a live video stream of the launch onthe web.
Explanation of NASA’s launch countdown. T-20 minutes doesn’t necessarily mean there’s 20 minutes until launch.
Edward Tufte, well known amongst information & Web designers for his trilogy of ID bibles, puts a bit of magic into the possibility of Earth’s first contact with aliens:
Since the principles of physics hold everywhere, magic is conceivably a cosmological entertainment, with the wonder induced by theatrical illusions appreciated by all, regardless of planetary system. Accordingly the plaque aboard the Pioneer spacecraft for extraterrestrial scrutiny billions of years from now might have escaped from its conspicuously anthropocentric gestures by showing instead the universally familiar Amazing Levitation Trick.
Who says information designers don’t have a sense of humor?
