Abstract
This paper covers Hubble's time and place in his scientific era, a compact biography and a brief explanation of his scientific achievements. It looks at how he discovered that there are more galaxies than just the Milky Way and how he tackled two of the most fundamental questions about the universe, its age and size.

From the Paper
"Born in 1889, Edwin Hubble grew to be a very "large mass of ego," as author Bill Bryson states in A Short History of Nearly Everything (2003) (114). He was born in a small Missouri town on the edge of the Ozarks and grew up in Wheaton, Illinois; on the outskirts of Chicago. His father was a successful insurance executive, so life was always calm and Hubble abiding. Accordingly, Hubble was remarked to be a tough and poised athlete, charismatic, chic, and immensely good-looking-"handsome almost to a fault," in the words of William H. Cropper; as well as "an Adonis" in the words of another admirer (115). These fated gifts were used more or less in constant acts of valor-rescuing drowning swimmers, leading frightened men to safety across the battlefields of France, embarrassing world-champion boxers with knockdown punches in exhibition bouts."
