 Expand the universe, then find the length of the shortest path between every pair of galaxies. **What is the sum of 
 these lengths**?
+
+# Part Two ---
+The galaxies are much **older** (and thus much **farther apart**) than the researcher initially estimated.
+
+Now, instead of the expansion you did before, make each empty row or column **one million times** larger. That is, each 
+empty row should be replaced with `1000000` empty rows, and each empty column should be replaced with `1000000` empty 
+columns.
+
+(In the example above, if each empty row or column were merely `10` times larger, the sum of the shortest paths between 
+every pair of galaxies would be **`1030`**. If each empty row or column were merely `100` times larger, the sum of the 
+shortest paths between every pair of galaxies would be **`8410`**. However, your universe will need to expand far 
+beyond these values.)
+
+Starting with the same initial image, expand the universe according to these new rules, then find the length of the 
+shortest path between every pair of galaxies. **What is the sum of these lengths**?
