Thoughts on Week 1: The Meaning of Time

The overall feeling I left class with was a pleasant intellectual excitement. I really loved learning about the arrows of time, even though I'm still fuzzy on how they are all reversible. I hadn't heard about the Red Shift before the class discussion, so that was a surprise and good bit of information. I makes me wonder what's going to happen if the universe just expands infinitely and how the universe started in a small dense ball. Weirdly enough, I prefer uncertainty over certainty. I remember in high school, I argued, as a senior, that math wasn't always reliable or infallible, because humans process the equations and factors or write the algorithms and there's always room for error when humans are involved. I was met with a lot of passionate disagreements, but I retain that feeling today: we can't really know for certain whether we're right or wrong. Mostly I believe this because everyone experiences reality differently, people's opinions change, and memories can be edited. I don't find uncertainty that unsettling, unless you have the image of unsettled dust, kicked up by traveling feet, and requiring you to take some time to stop and think about where you're going next. Maybe it would be better to charge forward in life, steadfast in my knowledge and capabilities, but I do believe that being open to not knowing encourages me to retain that childlike interest in the big questions.
