When I first saw Cosmos as a kid nothing fascinated me more than Sagan’s explanation of 4 dimensions. He used the concept of a tesseract to help illustrate hyper dimensionality. The concept is absolutely riveting the idea that there exists space around us that is unknowable because our cognitive apparatus is not up to the task. I remember thinking to myself that perhaps this is the realm of gods and ghosts and though visitors from a hyperdimesion can visit us we are forever condemned to never visit them we can only catch a glimpse of them as they pass through our tiny, insignificant plane of existence. We are bound by three dimensions.
The truth, though sad, inspires the imagination. Not only is the universe unbound in all directions that we are capable of peering into it’s possibly unbounded in a way that is utterly incomprehensible to us. This was plenty of information to inspire a seven year-old for life. I still sometimes find myself, lost in thought, wondering how to imagine a 4 dimensional cube a tesseract.
I’ve posted the clip that continues to inspired me to imagine and dream a little differently. Watch it and let me know what you think about.
