Satellites

Well I believe that my ability to share information has improved by satellites is because we can share information across the world instead of 100 miles. Also some of our cell phones need to depend on satellites to connect us to other people across the world. If we did not have them information would more than likely would stay in a state or move very slowly just to get across the nation. Another thing with the space exploration we discovered that there are other galaxies besides our own and nebulas from light-years away which we see by using the Hubble telescope. Using this device we tell that the stars are moving further apart from each other and not just by rotating either by distance.
