Almost Feeding Time.

“‘It’s a bit like the moment before a penalty shot in soccer,’ said astrophysicist Stefan Gillessen…Everyone knows a shot is about to be taken, but nobody knows outcome will be. ‘This is the most tense moment when one player is trying to shoot against someone on the other side’…No matter the outcome, ‘it will be absolutely stunning to see the physics at work.'”

With an array of telescopes, astronomers are watching a gas cloud waft dangerously close to the supermassive black hole at the center of our galaxy “this month” (Of course, it already happened ages ago, and we’re just now being apprised of it.)

“The gas cloud…could either continue on its current orbit and slingshot around the black hole or it could run into surrounding gas and dust, which will make it lose speed and start sliding down toward the black hole. The first scenario could give scientists insight into the evolution of galaxies and better understand the history of our Milky Way’s own black hole. In the second case, they might get to watch the black hole consume a sizable dinner.” Say hi to Maximillian for me.

As A Matter of Fact, It’s All Dark.

“‘There is no escape from a black hole in classical theory,’ Hawking told Nature. Quantum theory, however, ‘enables energy and information to escape from a black hole’…[The paper] does away with the notion of an event horizon, the invisible boundary thought to shroud every black hole, beyond which nothing, not even light, can escape. In its stead, Hawking’s radical proposal is a much more benign ‘apparent horizon’, which only temporarily holds matter and energy prisoner before eventually releasing them, albeit in a more garbled form.”

Also in potentially earth-shattering space news, Stephen Hawking — “one of the creators of modern black-hole theory” — has released a new paper (not-yet-peer-reviewed) arguing that there are no black holes, really: Quantum theory suggests that matter eventually escapes from them. “A full explanation of the process, the physicist admits, would require a theory that successfully merges gravity with the other fundamental forces of nature. But that is a goal that has eluded physicists for nearly a century.”

Distant Mirrors, and a Devouring Hunger.


“‘This is a major milestone on the road to finding Earth’s twin,’ said Douglas Hudgins, a scientist with the Kepler program…Kepler-22b, located about 600 light years away, has a radius 2.4 times bigger than the Earth, making it the smallest planet ever found in the middle of the habitable zone around a star.” Among the several fascinating announcements in astronomy in recent weeks (including Hubble passing the 10,000th mission mark), scientists announce the discovery of a faraway habitable planet, Kepler-22b. “Scientists don’t yet know whether it is a rocky, gaseous or liquid-covered planet.” But, don’t worry — the Air Force has top men looking into the situation. Top…men.

Moreover, just today scientists announced the discovery of two Earth-sized planets — Kepler 20e and Kepler 20f. “‘For the first time, we’ve crossed the threshold of finding Earth-size worlds,’ Torres says. ‘The next step is having an Earth-size planet in the habitable zone.’” And apparently Kepler 20f may have once had water, not unlike a planet closer to home…

This is the single most bullet-proof observation that I can think of that we’ve made this entire mission regarding the liquid water.” Something to consider if we don’t manage to tackle global warming by 2006 — the prior existence of water on Mars is further confirmed through a trail of gypsum left within an ancient rock. “Both the chemistry and the structure ‘just scream water,’ Squyres added.

And, on a grander scale, astronomers have begun to uncover supermassive black holes (no, not those ones) at the centers of galaxies. These are “the biggest, baddest black holes yet found in the universe, abyssal yawns 10 times the size of our solar system into which billions of Suns have vanished like a guilty thought.” In other words, plenty of room for Maximillian Schell to get lost in there…Tread carefully.

A Light in the Deepest Dark.


‘We think there are only about 100 bright quasars with redshift higher than 7 over the whole sky,’ concludes Daniel Mortlock, the leading author of the paper. ‘Finding this object required a painstaking search, but it was worth the effort to be able to unravel some of the mysteries of the early Universe.’

European astronomers find the farthest quasar yet discovered, 12.9 billion light years away and dating to only 770 million years after the Big Bang. “This brilliant beacon, powered by a black hole with a mass two billion times that of the Sun, is by far the brightest object yet discovered in the early Universe.

“Although we think of black holes as somehow threatening, in the sense that if you get too close to one you are in trouble, they may have had a role in helping galaxies to form — not just our own, but all galaxies.” German astronomers believe they have discovered a black hole right in the center of our Milky Way. “According to Dr Robert Massey, of the Royal Astronomical Society (RAS), the results suggest that galaxies form around giant black holes in the way that a pearl forms around grit.”

And, if that wasn’t heady enough news to wrap one’s mind around, see also this article on loop quantum cosmology (LQC) and “The Big Bounce.”LQC has been tantalising physicists since 2003 with the idea that our universe could conceivably have emerged from the collapse of a previous universe. Now the theory is poised to make predictions we can actually test. If they are verified, the big bang will give way to a big bounce and we will finally know the quantum structure of space-time. Instead of a universe that emerged from a point of infinite density, we will have one that recycles, possibly through an eternal series of expansions and contractions, with no beginning and no end.” (Both links via Dangerous Meta.)

Not Exactly Soundgarden.

“The more black holes eat, the more they spill, and it is widely thought that their feeding frenzies power the violence seen in the nuclei of many galaxies, including the powerful quasars that are so bright they outshine their parent galaxies.” The NY Times delves into the strange sounds emanating from black holes. “The frequency of these waves was equivalent to a B flat, 57 octaves below middle C, the astronomers calculated.
