AMAZING FACTS

If you unraveled all of the DNA in your body, it would span 34 billion miles, reaching to Pluto (2.66 billion miles away) and back...six times. Almost all of ordinary matter (99.9999999% of it) is empty space. If you took out all the space in our atoms, the entire human race (all 7 billion of us) would fit into the volume of a sugar cube. Many of the atoms your made of, from the calcium in your bones to the iron in your blood, were brewed up in the heart of an exploding star billions of years ago. In fact, your body contains relics from the creation of the Universe. Almost all of your hydrogen atoms were formed in the Big Bang, about 13.7 billion years ago. And back in the days before digital television, if you tuned your TV between stations, a small percentage of the static you would see would actually be the afterglow of the Big Bang. Light from stars takes so long to travel, that when you look at the stars you're actually peering deep into the past. NASA'S Hubble Telescope can look as far back as 13 billion years ago.
