3-D Map of our Known Universe

Just to put this into perspective for everyone- each one of those  lights is a galaxy like our Milky Way. In our Milky Way Galaxy we are in a tiny local group of planets- our solar system- when you look at our galaxy we are a barely distinguishable point of light among the millions of other points of light- those other points of light are other solar systems like our local group. In the Milky Way Galaxy alone, there are more stars than there are grains of sand on all of the beaches of our little planet. This is just what is known so far- The vastness of the Universe is almost inconceivable ...our little Milky Way Galaxy is 100,000 light years across - meaning it takes light 100,000 years to travel that distance...
