Ontario Science Centre

It was a long time since I've been to the Ontario Science Centre, and since I never blogged it in the 'Things to Do Around Town' section of my blog, this cold and blustery fall afternoon seemed as good as a time as any.  As you enter the Science Centre you will be taken down a long hallway (known as 'The Bridge').  This was one of my favorite spots in

the Science Centre as a child because of the awesome views of nature out of the windows.

Today, the views are still there and just as awesome, as well as a long line of ancient rocks up to four billion years old (the actual rocks aren't that old, but tiny grains in them called zircons are.)  The earth is 4.5 billion years old.  You may wonder why the oldest rocks aren't that old too?  It turns out shortly after the Earth formed, in the violent early days of the solar system, it was hit by a Mars-sized planet and mostly liquified into lava again! The debris launched into space coalesced and became our Moon. It's mind-blowingly daunting and humbling that a human lifetime on this scale is a thousandth of a millimetre, much thinner than a coat of paint!
