Via Lactea, or milky way galaxy, is home to an estimated 100,000 million stars. With that in mind have you ever wondered if we are alone in this universe? I don't see how we could be. Take a look at this linked picture and try to talk me into believing it's even a possibility. I have to warn that the size of this picture is huge but you'll get to put our blue green planet to scale within our observational universe.
Existence to scale
