What does the universe look like? Answered
I watch these magnificent programs about the universe, so wonderfully explained by Morgan Freeman. I am puzzled with one question. How can the science predict the size of our galaxy in somewhat vivid details?
So, here is my analogy. With the space technology at hand, taking a picture of our own galaxy is the same as taking a picture of the Empire State building from one of its balconies.
Can someone please elaborate on this subject.
