One Giant Leap...
39 years ago today humans first walked on the Moon. For most of us born since then, it is hard to imagine billions of people watching the event together. Despite the Cold War and protests, for one brief moment the human race was as one. "We Came in Peace For All Mankind," the plaque says. Could it happen again?
The 1-minute video also mentions the Lunar Laser Ranging Experiment. This device, simple as a bicycle reflector, was a giant leap for physics. It allowed accurate measure of the Moon's distance and more checks on General Relativity. LLRE also gave one more indication that the speed of light is slowing down.
In 1969 the human race was even more divided than today. Nations were divided by an Iron Curtain and Third World. Personal computers and phones were science fiction. Colour television was reserved for a few. Today's blogs and internet allow us to gather in small communities. However, technology also allows the whole globe to witness a single event. Within 11 years the world will again see humans walk the Moon. Can the human race again unite behind one moment?
