Pulsars: The universe's gift to physics
Sunday 27th of May 2012 08:28:06 AM
Posted by admin / Under Gravity Park USA
| Pulsars, superdense neutron stars, are perhaps the most extraordinary physics laboratories in the universe. Research on these extreme and exotic objects already has produced two Nobel Prizes. Pulsar researchers now are poised to learn otherwise-unavailable details of nuclear physics to test general relativity in conditions of extremely strong gravity, and to directly detect gravitational waves with a “telescope” nearly the size of our galaxy. Neutron stars are the remnants of massive stars that exploded as supernovae. They pack more than the mass of the Sun into a sphere no larger than a medium-sized city, making them the densest objects in... |

| Dear Dave, I was wondering why you recommend doing a fresh budget every month. Once you’ve figured out your expenses and income, won’t the same budget work month to month? Kara Dear Kara, I understand what you’re saying, but if you look closely at every month, you’ll see pretty quickly that they’re not all created equal in terms of expenses. On top of that, if you work a commission-based job, your monthly income will fluctuate throughout the year. Now, there are some things that will remain pretty standard. A few things like your rent or mortgage payment will probably be... |

Experiments Show Gravity Is Not an Emergent Phenomenon
Sunday 27th of May 2012 08:28:06 AM
Posted by admin / Under Gravity Park USA
| The way gravity effects quantum particles proves that it cannot be an emergent phenomenon, says physicist. One of the most exciting ideas in modern physics is that gravity is not a traditional force, like electromagnetic or nuclear forces. Instead, it is an emergent phenomenon that merely looks like a traditional force. This approach has been championed by Erik Verlinde at the University of Amsterdam who put forward the idea in 2010. He suggested that gravity is merely a manifestation of entropy in the Universe, which always increases according to the second law of thermodynamics. This causes matter distribute itself in... |

'Free-floating' planets found with no star in sight

| An international team of astronomers claim to have found free-floating "planets" which do not seem to orbit a star.Writing in Nature, they say they have found 10 Jupiter-sized objects which they could not connect to any solar system. They also believe such objects could be as common as stars are throughout the Milky Way. The objects revealed themselves by bending the light of more distant stars, an effect called "gravitational microlensing".Objects of large enough mass can bend light, as Albert Einstein predicted. If a large object passes in front of a more distant background star, it may act as a... |

Blinded with 'science' - Atheist's worst nightmare takes apart Hawking's 'design' flaws

| God didn't create the universe, Stephen Hawking says in his latest book, "A Grand Design." Rather, the renowned physicist writes, "Because there is a law such as gravity, the universe can and will create itself from nothing." Everything – created from nothing? The assertion begged a reply from the author of "Nothing Created Everything: The Scientific Impossibility of Atheistic Evolution." "It is embarrassingly unscientific to speak of anything creating itself from nothing," said Ray Comfort, a best-selling author and acclaimed minister who's confronted and confounded some of the world's most accomplished atheists.

| As Sir Isaac Newton himself replied in response to similar questions, "hypotheses non fingo." Which roughly translates as "I don't have a clue." That such a simple question, about so common a phenomenon, has defied a direct answer for centuries might explain why the physics world has been atwitter lately over a novel attempt to resolve the riddle. A flurry of recent papers have examined this new idea, which mixes principles from string theory and black hole physics with basic old-fashioned thermodynamics. If this notion is right, gravity turns out to be a special sort of entropy, a result of... |

| Physicists struggling to reconcile gravity with quantum mechanics have hailed a theory – inspired by pencil lead – that could make it all very simpleIT WAS a speech that changed the way we think of space and time. The year was 1908, and the German mathematician Hermann Minkowski had been trying to make sense of Albert Einstein's hot new idea - what we now know as special relativity - describing how things shrink as they move faster and time becomes distorted. "Henceforth space by itself and time by itself are doomed to fade into the mere shadows," Minkowski proclaimed, "and... |

| When scientists send their spacecraft across the universe, they save fuel by performing “slingshot fly-bys”. This is where, rather than firing up the thrusters, the craft changes its trajectory by harnessing the enormous gravitational pull of a planet. However, this trick has had an unexpected side-effect: it seems to produce a change in speed that no one, since it was first discovered in the early 1990's, can account for. Experts are intrigued by the fact that while the acceleration is tiny and has no significant effect on NASA missions, it holds great interest because no explanation based on conventional physics... |

| Rethinking relativity: Is time out of joint? EVER since Arthur Eddington travelled to the island of Príncipe off Africa to measure starlight bending around the sun during a 1919 eclipse, evidence for Einstein’s theory of general relativity has only become stronger. Could it now be that starlight from distant galaxies is illuminating cracks in the theory’s foundation? .... Yet it is still not clear how well general relativity holds up over cosmic scales, at distances much larger than the span of single galaxies. Now the first, tentative hint of a deviation from general relativity has been found. While the evidence... |

| Can we calculate the gravitational field of a mass moving close to the speed of light? Franklin Felber (Starmark Inc) believes he can, with implications for propulsion. Back in 2006 we looked briefly at Felber’s work, describing what the physicist believes to be a repulsive gravitational field that emerges from his results. Felber discussed the matter at the Space Technology and Applications International meeting that year, where he presented his calculations of the ‘relativistically exact motion of a payload in the gravitational field of a source moving with constant velocity.’ Above a certain critical velocity, Felber believes, any mass... |

The architect of doubly special relativity thinks so.In his youth, there were two things that regularly competed for Giovanni Amelino-Camelia’s attention: his favorite soccer team, Napoli, and "anything that came close to being scientific." And since Napoli was struggling in the Italian soccer league in the summer of 1978, Amelino-Camelia found himself watching a series of programs on special relativity instead of soccer. "That was really the point of no return for me," he remembers. "Although I was 13-years... |
Towards a New Test of General Relativity? (Generating Gravity in the Lab)

| Scientists funded by the European Space Agency believe they may have measured the gravitational equivalent of a magnetic field for the first time in a laboratory. Under certain special conditions the effect is much larger than expected from general relativity and could help physicists to make a significant step towards the long-sought-after quantum theory of gravity. Just as a moving electrical charge creates a magnetic field, so a moving mass generates a gravitomagnetic field. According to Einstein's Theory of General Relativity, the effect is virtually negligible. However, Martin Tajmar, ARC Seibersdorf Research GmbH, Austria, and colleagues believe they have measured... |

| ABHAY ASHTEKAR remembers his reaction the first time he saw the universe bounce. "I was taken aback," he says. He was 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. What on earth was happening? Ashtekar wanted to be sure of what he was seeing, so he asked his colleagues to sit on the result for six months before publishing it in 2006. And no wonder. The theory... |
Electric Gravity in an Electric Universe
Sunday 27th of May 2012 08:28:06 AM
Posted by admin / Under Gravity Park USA
~~~snip~~~ Electromagnetic waves are far too slow to be the only means of signalling in an immense universe. Gravity requires the near-instantaneous character of the electric force to form stable systems like our solar system and spiral galaxies. Gravitationally, the Earth ‘sees’ the Sun where it is this instant, not where it was more than 8 minutes ago. Newton’s famous law of gravity does not refer to time. We must have a workable concept of the structure of matter that satisfies the observation that the inertial and gravitational masses of an object are equivalent. When we accelerate electrons or protons...
