That means this journey took at least one thousand days. Over three years. Well, it takes light twelve years to make this trip, so it should take me a long time too. Oh, right. Relativity. I have no idea how much time it took. Or, rather, I have no idea how much time I experienced. When you get going near the speed of light, you experience time dilation. More time will have gone by on Earth than I have experienced since I left Earth. Relativity is weird. Time is of the essence here.
