CNN doesn't seem so silly now, does it?

The universe may just be a giant (five dimensional) hologram.

Black Holes, Killer Asteroids and Spaghetti-fication, oh my!

Larry Niven warned everyone about it. MetaFilter, too: Try to escape. Quantum black holes is dangerous.

Quantum Mechanics: Myths and Facts

XMLicious — Mon, 25 Feb 2008 13:21:29 -0800

Quantum Mechanics: Myths and Facts (pdf), a recently-updated paper on the Cornell arXiv peer-review site. By Hrvoje Nikolić of the Rudjer Bošković Institute in Croatia. Note: the presence of a paper on arXiv does not necessarily mean it has been reviewed and is not equivalent to having been published in a journal.

Don't give me any of that intelligent life crap, just give me something I can blow up

For a star as big as our universe the calculated vacuum energy inside its shell matches the value of dark energy seen in the universe today. "It's like we are living inside a giant dark energy star" say two physicists and their collegues. Dark energy stars may do away with the concept of black holes. (also seen recently on )

Massive explosion rocks NASA

Massive explosion rocks NASA And Pasadena, and a few other places, too. It's not every day you get to watch a black hole form. Includes cool animation (.mov file). Seems the gamma ray burst detector picks up two or three significant events every month or so.

Italo Calvino's Cosmicomics

"I was willing to bet that there was going to be a universe, and I hit the nail on the head." The other day we had Avram Davidson, which got me thinking of Calvino's Invisible Cities, but all the recent talk about black holes made me remember that Italo Calvino is at his most charming when he's playing with physics, math, and cosmology in Cosmicomics.

Black Holes Merge. Massive layoffs expected throughout galaxy.

Black Holes Merge. Massive layoffs expected throughout galaxy. Analysts predict big payoffs for the economy, however. "A burst of gravitational waves that could warp the very fabric of space will go a long way towards increasing shareholding value," said one economist. Both black holes had recently suffered a dramatic drop in stock price, and were under the threat of hostile takeover from industry leader Black Hole 86184-B before the merger was announced, which took Wall Street pundits off guard. "Much to our surprise, we found that both were active black holes," Stefanie Komossa of the Max Planck Astro-Economics Institute in Germany, said in a statement. Proponents of big business greeted the announcement with pleasure: "This supports the idea that black holes can grow to enormous masses in the centres of galaxies by merging with other black holes."

Aonther massive celestial object, with a companion star in tow,

Smart Dalek — Tue, 19 Nov 2002 13:29:03 -0800

Another massive celestial object, with a companion star in tow, has been discovered hurtling through the Milky Way. Unlike similar discoveries confirming the bow shock theory of stellar dynamics, this week's phenomenon is considerably older, as it's an aftereffect of the galactic core's formation. The French and Argentine astromoners making the discovery believe what they've witnessed may be a black hole, though theoretically, the collasped matter may be a gravistar.

Wot, no black holes? Those wacky boffins in science land have already had a pop at the Higg's boson, but now they're moving on to everybody's favourite theoretical singularity, with a new theory about what happens when a star kicks the astral bucket.

"Observing" other dimensions. The existence of tiny black holes, produced by cosmic rays in the Earth's atmosphere, if confirmed by the Auger cosmic ray observatory, might provide evidence for other dimensions beyond Space and Time.
Amazing how theories considered untestable by experiment a few years ago are turning into "real" science.

Black holes blow as well as suck. It's amazing what we find out about the universe. Imagine what we don't know?
