Astronomy is said to be a humbling profession. The universe is estimated to be 13.7 billion years old and 156 billion light years wide. As of 2006, the observable universe is thought to contain about 7 × 10^22 stars, organized in about 100 billion galaxies, which themselves form clusters and superclusters. The number of galaxies may be even larger, based on the Hubble Deep Field observed with the Hubble Space Telescope. The Hubble Space Telescope has discovered galaxies which are over 13 billion light years from Earth. I am a little upset because I just broke my watch band which is about 1 inch wide.  Here is an awe-inspiring article where world-renowned astronomer Carl Sagan reacts to a photo shot by Voyager 1 in 1990. I hope you enjoy it. Last edited by Matt; 11-06-2006 at 07:16 PM. |

Did you mean to say Astronomy instead of Astrology?

I'm interested, if it is possible to go straight on away from our planet and (after few aeons pass, of course  ) to arrive back from opposite direction. Maybe law of relativity kicks in and you'd arrive before departure?Another interesting consideration it that whether matter density in universe stays constant - whether new matter is continually created to offset the expansion. Scientists say that all matter in universe was created from the vacuum so, that the vacuum discharged into matter in steps during early stages of universe. And apparently vacuum still has hidden energy, in fact scientists still doesn't know what makes for 9/10 of all matter in space. | |
