Results: Even in my advanced years I am still curious to learn new things or learn more about old things. I hope you are too.

We have seen video clips of salmon swimming upstream to spawn and it is a wonder of nature. When Mr St. Helens blew its top, many lakes and rivers disappeared and new ones eventually replaced them as water was diverted. Yet some lakes that were newly formed and won't have a river flowing from them for several years while the water level rises enough to create one, nevertheless have fish in them. Where did these fish come from? The answer is from migrating birds. When ducks eat fish eggs, some of them can pass through the digestive system unharmed and hatch in new waterways. Did you know this?

You may have heard the expression "We are what we eat." What we eat today is quite different from what our ancestors ate thousands of years ago in the time of Abraham and our bodies have changed slightly as a result. Darwin had an explanation for how species adapt to changes if given enough time to do so. But what changes and circumstances can explain the creation and/or development over the years of the platypus from Australia? The first scientists to see one were convinced it had been assembled from multiple different animals. Do you think the same?

The previous question dealt with how species change and develop over time. There are other species that have remained essentially unchanged for millions of years. Nature apparently got it right the first time and no change was necessary for the species to survive. One such creature is the shark which has been around for longer than the rings of Saturn. Saturn's rings are estimated to be no more than 400 million years old. Comparatively, sharks date back to the late Ordovician period, or about 450 million years ago. Did you know this?

Our atmosphere protects us from space debris, some of which is coming towards us at incredible speeds. The fastest meteorite recorded entered the atmosphere at 40,000 mph and the fastest asteroid is about 161,000 mph before burning up quite spectacularly. But if a tiny needle weighing just one gram hit earth at 99.9999% of the speed of light it would have huge mass (E = MC2)., It would have the kinetic energy of three Tsar bombs, (the biggest nuclear weapon ever detonated at 50 megatons each) with the light, heat and shock wave to match. Even if our atmosphere took care of it for us it would be quite the light show. Have you ever seen something burn up in our atmosphere?
