My Facebook friend Staci was lamenting yesterday that she was having one of those days where she felt at odds with the universe, that she was such a tiny, trivial, insignificant speck in the grand cosmic scheme of things. A feeling she blamed on the landing of the Mars Curiosity rover, since the sheer scale of what they accomplished is outside of the comprehension of someone in their day-to-day travels. And yet, when you take a big look at it, we did little more than fire a bullet at a target across our yard. When you start to really explore the scale of the universe, that’s when it really starts to get to you.
