No on was general relativity the first major new theory of gravity but it was the first one since Isaac Newton's more than 250 years earlier. Many of the predictions of general relativity have been quantitatively confirmed by experiment. It also talks about how Einstein and others applied general relativity to the structure and evolution of the universe as a whole.Molecular Workbench

*********************BBC NEWS | Science & Environment | Black hole confirmed in Milky Way
They tracked the movement of 28 stars circling the centre of the Milky Way, using two telescopes in Chile. The black hole, said to be 27,000 light years from Earth, is four million times bigger than the Sun, according to the paper in The Astrophysical Journal. Black holes are objects whose gravity is so great that nothing - including light - can escape them.
There is a giant black hole at the centre of our galaxy, a 16-year study by German astronomers has confirmed. They tracked the movement of 28 stars circling the centre of the Milky Way, using two telescopes in Chile.

If this doesn't blow your socks off, then Hogan has an even bigger shock in store: "If the GEO600 result is what I suspect it is, then we are all living in a giant cosmic hologram."

article from New Scientist about the world being a hologram
According to Craig Hogan, a physicist at the Fermilab particle physics lab in Batavia, Illinois, GEO600 has stumbled upon the fundamental limit of space-time - the point where space-time stops behaving like the smooth continuum Einstein described and instead dissolves into "grains", just as a newspaper photograph dissolves into dots as you zoom in.

If this doesn't blow your socks off, then Hogan, who has just been appointed director of Fermilab's Center for Particle Astrophysics, has an even bigger shock in store: "If the GEO600 result is what I suspect it is, then we are all living in a giant cosmic hologram."
A noise floor found in very small measurements means that our entire universe could be holographic. If true, this could have wide-ranging applications in space exploration, physics, computer science, philosophy, and other fields.
"The idea that we live in a hologram probably sounds absurd, but it is a natural extension of our best understanding of black holes, and something with a pretty firm theoretical footing. It has also been surprisingly helpful for physicists wrestling with theories of how the universe works at its most fundamental level."SuperMagnetMan Magnets

Inductive reasoning at it's finest.
In just over a day, a powerful computer program accomplished a feat that took physicists centuries to complete: extrapolating the laws of motion from a pendulum's swings. Developed by Cornell researchers, the program deduced the natural laws without a shred of knowledge about physics or geometry. The research is being heralded as a potential breakthrough for science in the Petabyte Age, where computers try to find regularities in massive datasets that are too big and complex for the human mind. (See Wired magazine's July 2008 cover story on "The End of Science.") "One of the biggest problems in science today is moving forward and finding the underlying principles in areas where there is lots and lots of data, but there's a theoretical gap. We don't know how things work," said Hod Lipson, the Cornell University computational researcher who co-wrote the program. "I think this is going to be an important tool."

I just finished reading this book. It's one of the best analysis of energy use I was given to read. Hurray for raw number with cited sources!
Using a charming, educational style that teaches how to think about this kind of number, how to estimate with it, and what it means, MacKay explains these concepts beautifully, with accompanying charts that make them vivid and clear, and with exhaustive endnotes that are as interesting as the text they refer to (probably the best use of end-notes I've encountered in technical writing -- they act like hyperlinks, giving good background on the subjects that the reader wants to find out more about while allowing the main text to move forward without getting bogged down by details). sensible personal advice for things you can do to reduce your energy consumption -- especially identifying those few badly designed devices in your home whose idle power-draw really is punitive and replacing them (one Ikea lamp he cites draws nearly as much switched off as running, because of a transformer design that was one penny cheaper to manufacture than a more efficient one would have been).

This is pretty awesome. It's a plain-English explanation of what rules should have to apply to any literary use of time travel, given what we know about space-time. "Time travel isn’t magic; it may or may not be allowed by the laws of physics — we don’t know them well enough to be sure — but we do know enough to say that if time travel were possible, certain rules would have to be obeyed." I was, of course, reading these rules and thinking of LOST, which, by my count, seems to play by all the rules expect maybe number three (but, in their defense, if you don't have some visual cue to the audience that time travel just happened, how would they ever know? I understand that it would happen in the real world, but you kind of need the flashing light as a storytelling device). Great read.
0. There are no paradoxes. 1. Traveling into the future is easy. 2. Traveling into the past is hard — but maybe not impossible. 3. Traveling through time is like traveling through space. 4. Things that travel together, age together. 5. Black holes are not time machines. 6. If something happened, it happened. 7. There is no meta-time. 8. You can’t travel back to before the time machine was built. 9. Unless you go to a parallel universe. 10. And even then, your old universe is still there.

Something to think about when you wonder if you “see” reality.
So we’re forced to realize a very interesting conclusion. The wavelength of a photon certainly reflects a color – but we cannot produce every color the human eye sees by a single photon of a specific wavelength. There is no such thing as a pink laser – two lasers must be mixed to produce that color. There are “real” colors (we call them pure spectral or monochromatic colors) and “unreal” colors that only exist in the brain.
While we consider this rather trivial today, at the time you’d be laughed out of the room if you suggested this somehow illustrated a fundamental property of light and color. The popular theory of the day was that color was a mixture of light and dark, and that prisms simply colored light. Color went from bright red (white light with the smallest amount of “dark” added) to dark blue (white light with the most amount of “dark” added before it turned black).Jiggmin.com - Effing Hail

Moore's Law is one of the few Moira threads we've teased out in our short history in the technium. There must be others. Most of the technium's predetermined developments remain hidden, not yet uncovered, by tools not yet invented. But we've learned to look for them. Searching, we can see similar laws peeking out now. These "laws" are reflexes of the technium that kick in regardless of the social climate. They too will spawn progress, and inspire new powers and new desires as they unroll in ordered sequence. Perhaps these self-governing dynamics will appear in genetics, or in pharmaceuticals, or in cognition. Once a dynamic like Moore's Law is launched and made visible, the fuels of finance, competition, and markets will push the law to its limits and keep it riding along that curve until it has consumed its physical potential.Is Quantum Mechanics Controlling Your Thoughts? | Subatomic Particles | DISCOVER Magazine

Humans don’t always make the most rational decisions. As studies have shown, even when logic and reasoning point in one direction, sometimes we chose the opposite route, motivated by personal bias or simply "wishful thinking." This paradoxical human behavior has resisted explanation by classical decision theory for over a decade. But now, scientists have shown that a quantum probability model can provide a simple explanation for human decision-making - and may eventually help explain the success of human cognition overall.

"Another is that combat in orbit would be very different from combat in "deep space," which is what you probably think of as how space combat should be – where a spacecraft thrusts one way, and then keeps going that way forever. No, around a planet, the tactical advantage in a battle would be determined by orbit dynamics: which ship is in a lower (and faster) orbit than which; who has a circular orbit and who has gone for an ellipse; relative rendezvous trajectories that look like winding spirals rather than straight lines."
First, let me point out something that Ender's Game got right and something it got wrong. What it got right is the essentially three-dimensional nature of space combat, and how that would be fundamentally different from land, sea, and air combat. In principle, yes, your enemy could come at you from any direction at all. In practice, though, the Buggers are going to do no such thing. At least, not until someone invents an FTL drive, and we can actually pop our battle fleets into existence anywhere near our enemies. The marauding space fleets are going to be governed by orbit dynamics – not just of their own ships in orbit around planets and suns, but those planets' orbits. For the same reason that we have Space Shuttle launch delays, we'll be able to tell exactly what trajectories our enemies could take between planets: the launch window.

Since its birth in the 1920s, physicists and philosophers have grappled with the bizarre consequences that his theory has for reality, including the fundamental truth that it is impossible to know everything about the world and, in fact, whether it really exists at all when it is not being observed. Now two groups of physicists, working independently, have demonstrated that nature is indeed real when unobserved. When no one is peeking, however, it acts in a really odd way.

monopoles gather to form a "magnetic current" like electricity. The phenomenon, dubbed "magnetricity", could be used in magnetic storage or in computing. Magnetic monopoles were first predicted to exist over a century ago, as a perfect analogue to electric charges. Although there are protons and electrons with net positive and negative electric charges, there were no particles in existence which carry magnetic charges. Rather, every magnet has a "north" and "south" pole. //"particles" which carry an overall magnetic charge. But they exist only in the spin ice crystals.
Researchers have discovered a magnetic equivalent to electricity: single magnetic charges that can behave and interact like electrical ones. The work is the first to make use of the magnetic monopoles that exist in special crystals known as spin ice.

"Until now, this has been a hypothesis," France's National Centre for Scientific Research (CNRS) said proudly in a press release.
According to the conventional model of particle physics, protons and neutrons comprise smaller particles known as quarks, which in turn are bound by gluons. The odd thing is this: the mass of gluons is zero and the mass of quarks is only five percent. Where, therefore, is the missing 95 percent? The answer, according to the study published in the US journal Science on Thursday, comes from the energy from the movements and interactions of quarks and gluons.YouTube - The Most IMPORTANT Video You'll Ever See Part 1 of 8

Our universe may have started not with a big bang but with a big bounce—an implosion that triggered an explosion, all driven by exotic quantum-gravitational effectsDid our cosmos exist before the big bang? - space - 10 December 2008 - New Scientist
LQC is in fact the first tangible application of another theory called loop quantum gravity, which cunningly combines Einstein's theory of gravity with quantum mechanics. Theories like this work out what happens when microscopic volumes experience an extreme gravitational force, as happened near the big bang, for example. Ashtekar rewrote the equations of general relativity in a quantum-mechanical framework. ABHAY ASHTEKAR saw the universe bounce back while watching a simulation of the universe rewind towards the big bang. Mostly the universe behaved as expected, becoming smaller and denser as the galaxies converged. But then, instead of reaching the big bang "singularity", the universe bounced and started expanding again. The theory that the recycled universe was based on, called loop quantum cosmology (LQC), had managed to illuminate the very birth of the universe - something even Einstein's general theory of relativity fails to do.
"Ashtekar later used this framework to show that the fabric of space-time is woven from loops of gravitational field lines."
Did our cosmos exist before the big bang
Loop Quantum Cosmology posits a different beginning to the universe.The Big Bang Was an Explosion OF Space, Not IN Space
At no point was matter spewing forth from anything. Space and time itself was being created first. Ordinary matter (atoms, molecules etc) was created out of tiny imbalances of energy left over from the inflationary period.
The Big Bang was not an explosion of matter into space, rather it was an explosion of space ITSELF, and since space and time are interconnected, we really have to say it was an explosion of space AND time, or space-time.STEPHEN HAWKING: How to build a time machine | Mail Online
THE aliens are out there and Earth had better watch out, at least according to Stephen Hawking. He has suggested that extraterrestrials are almost certain to exist — but that instead of seeking them out, humanity should be doing all it that can to avoid any contact.
THE aliens are out there and Earth had better watch out, at least according to Stephen Hawking. He has suggested that extraterrestrials are almost certain to exist — but that instead of seeking them out, humanity should be doing all it that can to avoid any contact. He's a smart man. Take his advice and don't fuck with aliens
"He concludes that trying to make contact with alien races is “a little too risky”. He said: “If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans.”"Hubble: Hubble Finds Unidentified Object in Space, Scientists Puzzled

Hubble: Hubble Finds Unidentified Object in Space, Scientists Puzzled
The headline and story made me think of Bruce Willis in Armageddon when he says, "You're NASA, you've always got a backup plan. You've probably got a team somewhere else thinking up ideas" because it's surprising that they can't even guess as to what this is.
[I]n a paper published last week in the Astrophysical Journal, scientists detail the discovery of a new unidentified object in the middle of nowhere.

From the November 2008 Scientific American Magazine | 62 comments Does Nature Break the Second Law of Thermodynamics? In seeming defiance of the second law of thermodynamics, nature is filled with examples of order emerging from chaos. A new theoretical framework resolves the apparent paradox By J. Miguel Rubí

discussion topic, allow students to discuss key points of article, provide them with selected passages. This is a good way to see if they understand as they will have to discuss how nature does and doesn't obey the laws of thermodynamics.Podstawy Fizyki

"Modeling the absence of centrifugal force"
What would happen to our oceans if the Earth stopped spinning ? http://www.esri.com/news/arcuser/0610/nospin.html
What would happen if the Earth stopped spinning?
The following is not a futuristic scenario. It is not science fiction. It is a demonstration of the capabilities of GIS to model the results of an extremely unlikely, yet intellectually fascinating query: What would happen if the earth stopped spinning? ArcGIS was used to perform complex raster analysis and volumetric computations and generate maps that visualize these results. the world as we know it earth's ellipsoid
If the earth's gravity alone was responsible for creating a new geography, the huge bulge of oceanic water—which is now about 8 km high at the equator—would migrate to where a stationary earth's gravity would be the strongest. This bulge is attributed to the centrifugal effect of earth's spinning with a linear speed of 1,667 km/hour at the equator. The existing equatorial water bulge also inflates the ellipsoidal shape of the globe itself.
