Here is what happened when professional astronomers pointed the Hubble Space Telescope at absolutely nothing and left it there, first for 10 days, and then for 11 days. Then they made the images into a 3-D presentation. Hang on to your seat! By the way, 13 billion light years are about equal to 880,000,000,000,000,000,000,000 (880 sextillion) miles. Be sure you have your sound on.
