  1. Quantum Gravity
  1. Gravitons May Link Subatomic Particles and Beginning of Time ( - Hogan and Stricherz)
      "Unlike subatomic particles that make up matter and energy as we know them, gravitons are elementary particles that compose the fabric of space and time."

      " 'No one has ever seen a graviton, but with these new efforts we might,' Hogan said. 'If you can see gravitons in these maps, then you'll start to see the essence of space and time and matter.' " 3-02

  2. Gravity Shielding Experiments (Fusion Information Center - Dart)
      "Although Podkletnov has said that tests ruled out the possibility that the claimed weight loss was the result of magnetic fields or air flow, his statement is suspect." Provides an alternative explanation to the "anti-gravity" effect that Podkletnov claimed for his experiments. 8-02

  3. Gravity Shielding Experiments (Interprise Mission - Matthews and sample)
      "Scientists in Finland are about to reveal details of the world's first anti-gravity device. Measuring about 12 inch across, the device is said to reduce significantly the weight of anything suspended over it."

      "The claim -- which has been rigorously examined by scientists, and is due to appear in a physics journal next month -- could spark a technological revolution. By combatting gravity, the most ubiquitous force in the universe, everything from transport to power generation could be transformed." Includes a diagram. 8-02

  4. Gravity Shielding Experiments - Applications (Brown)
      Discusses uses of a possible "anti-gravity" device, based on the work of Eugene Podkletnov. Includes a diagram. 8-02

  5. Landmark Experiment Confirms Space-Time Vortex Around the Earth (PC World)
      "In order to test Einstein’s theory, scientists sent a spinning gyroscope to orbit around the Earth. Space and time are melded together into something like a four-dimensional quilt (don't try making one at home), aptly called space-time. The Earth applies weight to this quilt, causing an indentation 'much like a heavy person sitting in the middle of a trampoline.' Gravity, then, is the path an object takes following the curve of that indentation."

      "Einstein theorized that the Earth’s rotation then causes that indentation to twist into a four dimensional swirl. With the axis of the gyroscope’s spin pointed at a fixed object (like a star), the Theory of Relativity indicates that without that swirl (or its 'frame-dragging effect') it would remain that way indefinitely, but with it the axis should drift out of alignment over time. The Gravity Probe B showed that Einstein was right, as the axis did in fact stray."

      "The experiment resulted in calculations exactly as Einstein predicted. The Gravity Probe B Mission will go down in history as one of the greatest physics experiments of all time. Clifford Will, who chairs an independent panel of the National Research Council tasked with monitoring and reviewing the results of the Gravity Probe B Mission said, 'this will be written up in textbooks as one of the classic experiments in the history of physics.'

  6. Principia Mathematica (
      "The Philosophiae Naturalis Principia Mathematica (Latin: "mathematical principles of natural philosophy", often Principia or Principia Mathematica for short) is a three-volume work by Isaac Newton published on July 5, 1687. It contains the statement of Newton's laws of motion forming the foundation of classical mechanics as well as his law of universal gravitation. He derives Kepler's laws for the motion of the planets (which were first obtained empirically)." 06-06

  7. Speed of Gravity Not Yet Proven (
      "Albert Einstein may have been right that gravity travels at the same speed as light but, contrary to a claim made earlier this year, the theory has not yet been proven." 6-03

  1. Gravity - Keys That Do Not Fall to the Floor (Education World - Cobb)
      Provides an experiment for children and teens to perform. 12-04
