Time seems to be a simple thing. And, in one sense, it is.
In many other ways it is immensely complicated. A lot of those complications come about because of individual perceptions, which are without limit.
Have you ever had a sense that your watch seems to be running slowly while your partner says his/her watch seems to be running too fast.
Perceptions of time are indeed mysterious and very difficult to understand and explain. If you are waiting impatiently, time seems to pass very slowly? If you are distracted as time passes, time seems to fly by?
How often have you returned from a 5 time zone trip to discover the first afternoon back that time seems to be passing very, VERY slowly–as you try to stay awake until bedtime? Have you ever watched a running race start, and then hear the starting gun shot moments later? Clearly the speed of sound is different from the speed of light? Why?
Some genius a long time ago–long before telescopes, etc.–figured out that the earth itself rotates daily and also rotates around the sun in about 52 weeks. That logically leads to 24 sixty- minute hours for the daily rotation, which in turn means seven 24 hour days a week.
From there, we have today’s basic time and distance system. It is not hard to see that while the physical movements remain the same, they might have been represented by comparable but different numbers.
Then Einstein figured out that the speed of light is 186,000 miles per second. [If I could explain how he reached that number, I probably would be doing something more worthwhile than simply writing this message!]
That fact by itself leads minds into a wonderland when they hear about distances like ‘light years’, each of which translates into —> Read More
