Powers of Ten

I first watched this at the Air and Space Smithsonian in Washington DC probably about 30 years ago and was so blown away I watched it two more times. Even now I still get a kick out of it. The Morgan Freeman version is a bit updated and lots of fun too but this ages well and is a tribute to the guys who produced it. Watch it sometimes if you think you're a big shot; it helps to remember that you are a tiny speck in a virtually limitless universe. And yet if you are a believer you know that you are so much more than that!

Simply amazing video. "We enter an area of vast inner space." That's one of the most amazing revelations. We think of space as a vast void of emptiness, but so is solid, dense matter, in actuality. If we could remove all the space making up all the atoms that make up the Empire State building (all the steel, concrete, glass, electrical wiring, etc), it would be about the size of a grain of rice. If we did the same for the desk you're sitting at, you would need a tunneling electron microscope to see it. That's why, the electro magnetic force is the strongest, most important force in the universe (gravity, of course, is not a force at all). Without it, you could put your hand through a solid object...but then again, your hand wouldn't appear as a solid object at all.
