It's about time!

The speed of light….really quick, right? Consider this. The space probe, Huygens landed at about 7:45 AM EST on the surface of a moon of Saturn named Titan. Titan is about 2.2 billion miles from us. The data sent back from the probe’s instruments will, of course travel at the speed of light, approximately 183,000 miles per second. It will still take the data 3 ½ hours to get here or in other words 1/3 the time it takes for the cable repair guy to make it from the cable shop to your home.
Let’s look at some other comparisons. Three and one/half hours also equals the length of time that passes

While your dog decides to take care of business on a frigid day
While water comes to a boil if you look at it
While you sit behind the car in front of you at a green light
While you are on hold for technical assistance on your computer
While Al Gore answers a question
While a heat pump raises the temperature of a room by 1 degree Fahrenheit
While you wait for your meal at Denny’s
While waiting to be seen in the average emergency room if and only if you are the only patient (Your results may vary)

Some other things are incredibly quick though. Researchers in California have defined the shortest recognizable period of time the as the ‘honkon’ which describes the interval between the traffic light in front of you turning green and the car behind you blowing its horn. You can look it up!

That’s my story and I’m sticking to it….
