We are toward the "edge" of the Milky Way. From what I understand, if it were physically possible to create an infinitely large plane upon which to create a scale model of the universe, with the earth being the size of the head of a pin, going sixty five miles an hour away from the earth toward the center of the galaxy on this model would take over fifty years.
I'd like to note also that there aren't merely "millions" of galaxy, but billions. I believe we factually know tat there are at least 100 billion galaxies. Which is incomprehensible.
