- Gravity Shielding Experiments Explained (PopularMechanics.com - Wilson)
"Isaac Newton, the first physicist, described gravity as an attraction between two masses (see illustration at top of page). Albert Einstein's general theory of relativity suggests mass actually causes space-time to warp around it. Imagine, for instance, the indentation created by placing a bowling ball on a soft bed.
Both theories explain why apples fall from trees. Scientists consider Einstein's theory superior because it explains also why light–which has no mass–appears to bend in strong gravitational fields."
"Most physicists believe that when NASA flips the switch on its gravity modification experiment, absolutely nothing will happen. Then again, it could start the countdown to a bold new era in space exploration." Editor's Note - The article is dated December, 1997. In August, 2002, Boeing Aircraft announced that it is building an anti-gravity device for NASA. 8-02
- 06-23-03 Speed of Gravity Not Yet Proven (SpaceDaily.com)
"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
- Dark Matter (Space.com - Weinstock)
"Eighty-four years after Albert Einstein introduced the world to his theory of general relativity, scientists are seeing that he was right all along about measuring what we now call dark matter."
"Astronomers supported by the National Science Foundation have found the first evidence of an effect called cosmological shear, a phenomenon predicted by Einstein’s theory, in which light from distant cosmic objects bends due to gravitational forces. What’s more, the detection of cosmological shear has allowed astronomers to track down significant amounts of dark matter, non-luminous matter whose presence in the universe has been predicted, but scantly detected until now." 12-03
- General Relativity (Wikipedia.org)
"General relativity (GR) or General relativity theory (GRT) is the theory of gravitation published by Albert Einstein in 1915." 10-04
- Special Relativity (Wikipedia.org)
"The Special relativity (SR) or Special theory of relativity is the physical theory published in 1905 by Albert Einstein. It replaced Newtonian notions of space and time, and incorporated electromagnetism as represented by Maxwell's equations. The theory is called "special" because it is a "special" case of Einstein's principle of relativity where the effects of gravity can be ignored." 10-04

- -06-06-07 The Universe Is Expanding Beyond Understanding (New York Times)
"When Albert Einstein was starting out on his cosmological quest 100 years ago, the universe was apparently a pretty simple and static place. Common wisdom had it that all creation consisted of an island of stars and nebulae known as the Milky Way surrounded by infinite darkness." 06-07
- -04-08-09 A New Theory on Autism (Time.com)
"The brain region that drew the attention of the authors is known as the locus coeruleus, a small knot of neurons located in the brain stem. Not a lot of high-order processing goes on so deep in the brain's basement, but the locus coeruleus does govern the release of the neurotransmitter noradrenaline, which is critical in triggering arousal or alarm, as in the famed fight-or-flight response. Arousal also plays a role in our ability to pay attention — you can't deal with the lion trying to eat you, after all, if you don't focus on it first. And attention, in turn, plays a critical role in such complex functions as responding to environmental cues and smoothly switching your concentration from one task to another. Those are abilities kids with autism lack."
"Certainly, many other parts of the brain govern concentration and attention, but the locus coeruleus does one other thing too: it regulates fever. Generations of parents of autistic kids have reported that when their child runs a fever, the symptoms of autism seem to abate. When the fever goes down, the symptoms return. In 2007, a paper in the journal Pediatrics reported on that phenomenon and confirmed that, yes, the parents' observations are right. What no one had done before, at least not formally, was tie it to the locus coeruleus — that is, until Drs. Dominick Purpura and Mark Mehler of the Albert Einstein College of Medicine published the idea this week."
"Nobody recommends inducing fevers to kick-start the locus coeruleus, since that could lead to all manner of side effects and other ills. Instead, Mehler and Purpura believe the likeliest answer is in medications that target noradrenaline brain receptors." 04-09
