Inconstant Cosmos.

“‘As you go back in time, the universe is pushing [outward] less and less,’ he said. ‘At some point, the pressure of dark energy is zero and is exerting no force on the universe. There is no explanation for it.'” New cosmological research announced yesterday further muddles our understanding of the expansion of the early universe and (once again) casts doubt on Einstein’s recently resurrected cosmological constant. “Schaefer based his findings on analysis of ultra-bright cosmic explosions called gamma-ray bursts, detected as far as 12.8 billion light-years away. He found that the most distant explosions appeared brighter than they should have been if the universe were accelerating at a constant rate.“

The Moon and Beyond.

“To become a multiplanet species, we must master the skills of extracting local resources, build our capability to journey and explore in hostile regions, and create new reservoirs of human culture and experience. That long journey begins on the moon — the staging ground, supply station and classroom for our voyage into the universe.” Astrophysicist Paul Sputig eloquently makes the case for a return to manned lunar exploration.

His Cup Runneth Dover.

“I’d like to say to the good citizens of Dover: if there is a disaster in your area, don’t turn to God, you just rejected Him from your city.” In a righteous froth over the recent turnover of intelligent designers in Dover, PA, Pat Robertson plays to type and calls out the Big Gun against Pennsylvania’s evolutionaries.

Gravity’s Rainbow.

“Suppose the asteroid is traveling 60,000 miles per hour. You want to make it 60,001.” Concerned by the possible 2036 impact of 99942 Apophis, two clever NASA astronauts have developed a tractor beam of sorts to pull asteroids off a possible collision course. Namely, send a relatively small (20-ton) ion-powered spacecraft to intercept and hover near the offending asteroid, and then let gravity work its mojo. “Even as the spacecraft counters the asteroid’s gravity, he said, its own gravity will pull the asteroid out of orbit.”

Designing School Boards.

In a mixed day for the Pastafari, the Kansas School Board opens the door to intelligent design, just as the voters of Dover, PA remove all eight school board members who were pushing the issue in the Keystone State. (Nevertheless, the Pennsylvania court challenge to intelligent design will continue.)

Googlarians unite.

“What’s going on? Google has become the new ground zero for the ‘other’ culture war. Not the one between Ralph Reed and Timothy Leary, but the war between Silicon Valley and Hollywood; California’s cultural civil war. At stake are two different visions of what might best promote authorship in this country. One side trumpets the culture of authorial exposure, the other urges the culture of authorial control.” University of Virginia Law professor Tim Wu surveys the controversy over Google Print, and makes a cautious plea for writers and academics to get behind the project.

Houston, we’ve had a problem.

“‘It is now commonly accepted that was not the right path,’ Griffin said. ‘We are now trying to change the path while doing as little damage as we can.'” In an interview with USA Today, NASA head Michael Griffin calls the Space Shuttle and ISS programs mistakes. Hmmm, interesting. This article reminded me of a quote I’ve seen attributed to Jerry Pournelle: “I always knew I’d live to see the first man walk on the Moon. I never dreamed I’d see the last.“

Release the Kraken.

And, would you believe it? Boss DeLay wasn’t the only nefarious and nightmarish tentacled creature to be captured in the past twenty-four hours. For the first time ever, Japanese scientists have succeeded in photographing a giant squid in its natural habitat. (I read about this late last night and had some very disturbing dreams about it. After all, there are older and fouler things than Orcs in the deep places of the world.) [Last link inspired by MysVamp.]
