The Farther Away We Look in Distance, the Further Back

Multiple Choice

The farther away we look in distance, the further back we look in time. This fact allows us to see what parts of the universe looked like in the distant past. For example, if we look at a galaxy that is 1 billion light years away, its light has taken 1 billion years to reach us-which means we are seeing it as it looked 1 billion years ago.
