How big is space? That is a question man has been asking since the beginning of time. When your grandparents were in school, it was thought that the Universe was very small, perhaps only 5000 light years across. 500 years ago it was thought that the Universe was only a little bit bigger than the Earth. In modern times, with the power of technology, we are finally starting to grasp the immense size of the Universe, and it is much bigger than anyone could have ever imagined.
