If you think that the science of astronomy hasn’t done anything for you, you have another think coming. As you know, I have some telescopes and every once in awhile I like to look out into space. My teachers back in grade school were predicting that when they told me to pay attention and quit gazing off into space. So, what has all this space gazing done for you? Well I am going to tell you about some of them.
Let’s look at Einstein first and his general theory of relativity. Back in 1971, scientists decided to test his theory by loading cesium atomic clocks in jet airliners which flew around the world, once eastward and once westward. I am not going into details but the experiment worked and from it the global positioning system we so much depend upon today was born.
Astronomers trying to detect signals from evaporating black holes (predicted by Stephen Hawking) developed equipment that turned into today’s wireless internet. Now, I bet all of you have used these two systems and some of us (me included) depend on them a lot.
