  crumbling up into a ball. Didn't it always seems strange that
  only light travels in straight lines? And only light has the

  spectrum. Think about this: space is always expanding. Well,
  where is space? Is it someplace "out there"? No. It is inside of
  us and all around us. We are always expanding and growing larger
  because the space in between is evenly growing bigger and
  larger. "
