“No matter how fast light travels, it finds the darkness has always got there first”*…

 

In our terrestrial view of things, the speed of light seems incredibly fast. But as soon as you view it against the vast distances of the universe, it’s unfortunately very slow…

An illustration of what one would see, traveling at the speed of light from the sun toward the edge of our solar system.  The filmmaker decided to end the video after Jupiter (at 45 minutes) to keep it “short,” since it could have gone on another half hour just to get to Saturn, let alone Uranus, Neptune, the former-planet Pluto (#neverforget), or the Kuiper Belt.

As we examine enormity, we might send sharply-focused birthday greetings to Theodore Harold “Ted” Maiman; he was born on this date in 1927.  A physicist and inventor, Maiman is credited with the invention of the first working laser, a synthetic ruby crystal laser, which was announced to the world in a July 7 press conference hosted by his employer, Hughes Aircraft.  Maiman’s work, for which he was granted a patent, led to the development of a variety of other types of lasers, and laid the foundation for the myriad uses in storage, scanning, communications, and other applications that have emerged since.

As we watch the world tick by, we might recall that it was on this date in 1923 that the Zero Milestone was dedicated just south of the White House at the north edge of the Ellipse, within President’s Park.  Intended as the initial milestone from which all road distances in the United States should be reckoned, at present only roads in the Washington, D.C. area have distances measured from it.
