The Deep Sky Frontier must be the world's largest web page. It is "9 quadrillion pixels wide by 9 quadrillion pixels tall. Thus it contains a large number of pixels:
8,100,000,000,000,000,000,000,000,000,000.
Using the arrow keys to scroll, see if you can move the scroll button even one pixel. On second thought, don't-- especially if you're the doggedly persistent type. To do so will take about seven times longer than your natural lifespan."
