  • Can You Escape the Force of Gravity? [What is gravity?]

    There’s no end to it. Gravity appears to be madly greedy and long armed. Members of the Virgo Super cluster are connected to each other, and they’re dozens of millions of light-years apart. Objects in the Pisces-Cetus Super cluster complex are even connected to each other by our invisible and obnoxiously possessive friend. And they are hundreds of millions of light years apart… In fact, you’re so popular that you are gravitationally pulled towards even most distant object in the observable Universe. And they, in turn, are linked to you. As a result, without the outward expansion and acceleration of...

    http://news.softpedia.com/news/The-First-Test-That-Proves-General-Theory-of-Relativity-Wrong-20259.shtml According to Einstein's theory of general relativity, a moving mass should create another field, called gravitomagnetic field, besides its static gravitational field. This field has now been measured for the first time and to the scientists' astonishment, it proved to be no less than one hundred million trillion times larger than Einstein's General Relativity predicts.

    It has been revealed by the British astronomer Patrick Moore that, on the morning of January 4th 2014, an extraordinary astronomical event will occur. At exactly 9:47 am, the planet Pluto will pass directly behind Jupiter, in relation to the Earth. This rare alignment will mean that the combined gravitational force of the two planets would exert a stronger tidal pull, temporarily counteracting the Earth’s own gravity and making people weigh less. Moore calls this the Jovian-Plutonian Gravitational Effect. Astronomers have long been aware that there would be an alignment of the planets on that date, when Mercury, Venus, Earth,...

    Sonner then set about to create quarks to see if he could watch what happens when two are entangled with each other. Using an electric field, he was able to catch pairs of particles coming out of a vacuum environment with a few “transient” particles in it. - Once he caught the particles, he mapped them in terms of space-time (four-dimensional space). Note: gravity is believed to be the fifth dimension because it can bend space-time [5th Dimension?], as you can see in these images of galaxies below. - Sonner then tried to figure out what would happen in the...

    The cosmic microwave background sky, here mapped by NASA's Wilkinson Microwave Anisotropy Probe, has a polarization, represented by white bars. Future experiments might measure the polarization with enough sensitivity to prove the existence of gravitons, the quanta of gravity. Can a quantum of gravity ever be detected? Two physicists suggest that it can — using the entire Universe as a detector. Researchers think that the gravitational force is transmitted by an elementary particle called the graviton, just as the electromagnetic force is carried by photons. But most of them despair about ever recording individual gravitons. That is because gravity is...

    With the recent announcement by NASA that the 36 year-old spacecraft Voyager 1 has officially entered interstellar space at a distance from the Sun about four times further than Neptune's orbit, and with Voyager 2 not far behind, it seems worthwhile to explore how humans managed to fling objects so far into space. Interplanetary spacecraft often use a maneuver called a gravity assist in order to reach their targets.

    Wall Street Journal ^ | 04/25/2013 | Gautam Naik
    Scientists have subjected Albert Einstein's famous theory of gravity to its toughest real-world test so far—and it has prevailed. Einstein's general theory of relativity states that objects with mass cause a curvature in space-time, which we perceive as gravity. Space-time, according to Einstein's theories of relativity, is a four-dimensional fabric woven together by space and time. For example, a bowling ball causes a dent in a mattress, and that dent changes the otherwise straight motion of a nearby marble on the same mattress. Similarly, the mass of the sun distorts the space-time around it. A body with less mass, like...

Normally, we don’t see how the Moon “wobbles” in its orbit or as it moves closer and farther away from Earth. But seeing the entire year compressed down to 5 minutes, we can see the...

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...

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...

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...

    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...

    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.

    Gravity highs (red) and lows (blue) on the Moon (Lunar nearside right, farside left)Science Results from the Japanese space agency's SELENE mission to the Moon are revealing details about why the lopsided lump of rock orbiting Earth is so unbalanced.The SELENE (Selenological and Engineering Explorer, or Kaguya) mission was launched in September 2007 to gather detailed geological information about the Moon. The results are published in Science1,2,3,4.Because the Moon has no atmosphere or weather to speak of, its geology has remained almost unchanged since it formed. So unpicking its structure could offer information about how the early Solar System —...

    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

    ~~~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...

    May 22, 2008: Meet MIT professor of physics Maria Zuber. She's dynamic, intelligent, intense, and she's on a quest for the Grail. No, not that Grail. Zuber is the principal investigator of the Gravity Recovery and Interior Laboratory — "GRAIL" for short. It's a new NASA mission slated for launch in 2011 that will probe the moon's quirky gravity field. Data from GRAIL will help scientists understand forces at play beneath the lunar surface and learn how the moon, Earth and other terrestrial planets evolved. "We're going to study the moon's interior from crust to core," says Zuber. "It's very...

    Pioneer spacecraft mystery may be laid to rest 14:30 15 April 2008 NewScientist.com news service Valerie Jamieson, St Louis What is making NASA's twin Pioneer spacecraft mysteriously drift off course, apparently defying the laws of physics? A rigorous new analysis suggests ordinary heat emission can at least partly explain the wayward probes' strange trajectories.Pioneer 10 and 11 were launched in the early 1970s and explored the outer solar system. But in 1980, mission scientists noticed that the spacecraft have unexpectedly drifted off course.Both spacecraft have been pulled a little harder than expected towards the sun, and since their launch, they...
  • Artificial black hole created in lab

    Everyone knows the score with black holes: even if light strays too close, the immense gravity will drag it inside, never to be seen again. They are thought to be created when large stars finally spend all their fuel and collapse. It might come as a surprise, therefore, to find that physicists in the UK have now managed to create an “artificial” black hole in the lab. Originally, theorists studying black holes focused almost exclusively on applying Einstein’s theory of general relativity, which describes how the gravity of massive objects arises from the curvature of space–time. Then, in 1974, the...

  • I AM IN MOURNING FOR MY CAT

    I have a small LSA airplane that is kind of weak on instruments. One thing I do not have is an attitude indicator so when I am in a cloud or fog, I do not know if I am in a bank, a dive, or a climb. Some of my "friends" and experienced aviators suggested I carry one of my cats with me. I was told to fly with my left hand on the yoke and toss the cat up and down with my right hand. As we all know, cats always land on their feet. I was told to...

    Obesity is more dangerous than smoking and will dramatically shorten the lives of millions, a landmark study has found. While smoking reduces life by an average of ten years, the research says being seriously overweight can cut life expectancy by as much as 13 years. The Foresight report, written by 250 leading scientists, says Britain's obesity crisis is so severe that it would take at least 30 years to reverse. If current trends continue, by 2050 about 60 per cent of men, 50 per cent of women and 25 per cent of children in the UK will be clinically obese...

    The 'Pioneer anomaly' – the mystifying observation that NASA's two Pioneer spacecraft have drifted far off their expected paths – cannot be explained by tinkering with the law of gravity, a new study concludes. The study's author suggests an unknown, but conventional, force is instead acting on the spacecraft. But others say even more radical changes to the laws of physics could explain the phenomenon. Launched in the early 1970s, NASA's Pioneer 10 and 11 spacecraft are drifting out of the solar system in opposite directions, gradually slowing down as the Sun's gravity pulls back on them. But they are...
  • Testing the Equivalence Principle [ "Mr. Galileo was right." ]

    ...what if the equivalence principle (EP) is wrong? Galileo's experiments were only accurate to about 1 [per cent], leaving room for doubt, and skeptical physicists have been "testing EP" ever since. The best modern limits, based on, e.g., laser ranging of the Moon to measure how fast it falls around Earth, show that EP holds within a few parts in a trillion (1012). This is fantastically accurate, yet the possibility remains that the equivalence principle could fail at some more subtle level. "It's a possibility we must investigate," says physicist Clifford Will of Washington University in St. Louis, Missouri. "Discovering...

    Satellites solve mystery of low gravity over Canada 20:16 10 May 2007 NewScientist.com news service Kelly Young The GRACE satellites have detected changes in the gravitational field over regions of Canada that can be attributed to the crust bouncing back after the melting of a glacier 20,000 years ago and convection in Earth's mantle (Illustration: Science/M Tamisiea) If it seems Canadians weigh less than their American neighbours, they do – but not for the reasons you might think. A large swath of Canada actually boasts lower gravity than its surroundings. Researchers have puzzled for years over whether this was due...
