This is not a scene from a sci-fi special effects movie. The green beam of light and red lunar disk are real enough, captured in the early morning hours of April 15, 2014. Of course, the reddened lunar disk is easy to explain as the image was taken during this week's total lunar eclipse. Immersed in shadow, the eclipsed Moon reflects the dimmed reddened light of all the sunsets and sunrises filtering around the edges of planet Earth, seen in silhouette from a lunar perspective. But the green beam of light really is a laser!
Shot from the 3.5-meter telescope at Apache Point Observatory in southern New Mexico, the beam's path is revealed as Earth's atmosphere scatters some of the intense laser light. The laser's target is the Apollo 15 retroreflector, left on the Moon by the astronauts in 1971. By determining the light travel time delay of the returning laser pulse, the experimental team from UC San Diego is able to measure the Earth-Moon distance to millimeter precision and provide a test of General Relativity, Einstein's theory of gravity.
Conducting the lunar laser ranging experiment during a total eclipse uses the Earth like a cosmic light switch. With direct sunlight blocked, the reflector's performance is improved over performance when illuminated by sunlight during a normal Full Moon, an effect fondly known as The Full Moon Curse.

After sifting through nearly 1,800 US policies enacted in that period and comparing them to the expressed preferences of average Americans (50th percentile of income), affluent Americans (90th percentile) and large special interests groups, researchers concluded that the United States is dominated by its economic elite.
So far, is anyone surprised? Yawn. Only then one asks the next question… why is half of the voting public just fine with this? Why do they let oligarch-controlled think tanks and oligarch-run mass media tell them to rage against every OTHER elite -- science, teaching, journalism, medicine… etc. -- that might stand up to oligarchy on our behalf, but never, ever question oligarchy itself?
In fact, there are reasons. Similar to how plantation lords talked a million poor while southerners who had been victimized by that landed elite, to instead turn and fight and die for them.
