1. Take a look at this website, developed by Florida State University in Tallahassee. It zooms from galaxies to atoms in steps of 10, providing enthralling pictures of the Universe, outside and within. The view begins (zoomed out to 10 to the power of +23) as a view of the Milky Way Galaxy viewed from a distance of 10 million light years and then Zooms in towards Earth in powers of ten: 10 million, to one million, to 100,000 light years, and then reaches a large oak tree, and begins to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons, down to 10 to -16 (100 attometers). The software does all the work. Just sit back and imagine how perfect our Universe is. You can play it forward and backward to be amazed over and over. You can then click to review the process in reverse. You can set the delay time for each view, and go forwards or backwards, auto or manual. Enjoy!
