This week was kinda interesting because I never thought of the world on different scales. As a human being, I tend to think of things as in reference to myself or the people around me. Thinking in such a way made me think that the scales were actually unreal. How could earth have the only living thing among so many galaxies. Moving on to a lower scale seems a little more realistic, since we were always taught that we are buidling blocks of protons, neutrons and electrons. This is what I assumed science was based on.
