I'm thinking back to a talk I attended a few months ago at UBC, "A Large-Scale Structure of Space and Time" and the "Powers of 10" video that was featured to explore measurement - from the sheer vastness of the atmosphere and beyond, to the more familiar everyday faces we encounter, and down to the minuscule atoms that play within the physical boundaries to define our existence. Brace yourselves: In a matter of a few minutes, this video will drag you out of Earth and bring you back, literally, and if you are like me, it will challenge your mind and put you in a state of existentialism.
As this leaves you thinking about how to mentally ground yourself, I think it's important to zoom precisely into where the mind fits into it all. It's only human to have a tendency to be anthropocentric, but it's also equally human to be curious and have the capacity to learn, with a brain and mind that is just as intricate as this universe itself. With this ability to learn and accumulate knowledge, the more skilled we become at shifting perspectives to evaluate our existence relative to other things...and therefore move away from the normal tendency to gravitate towards the anthropocentric standpoint. Perhaps, it's this ongoing battle within our minds about what matters allows us to push boundaries in science and knowledge, and ultimately pave the way for change (but now...are these changes significant in the larger scheme of things?). I'll let you sit on that thought and decide.
