light has an invariable speed limit, then that means that since the Big Bang it could only have traveled approximately 13.7 billion light years, because approximately 13.7 billion years have elapsed since the Big Bang. The distance that light is able to travel since the Big Bang creates the 'horizon' of the visible universe—this is about 47 billion light years (although light has only been traveling for 13.7 billion years, this number takes into account the expansion of space that is occurring as light is traveling
