My biggest regret in life is that I am not a physicist. I took physics in high school and almost did not pass the class, but I felt passionate about the subject. The poetry of mysterious concepts such as, âgeneral relativityâ, âwave particle dualityâ, and âthe 4th dimensionâ, filled my teenage imagination with wonder. To this day, when I feel bored/asleep in my life, I watch videos about black holes or string theory and it helps my mind re-open to the unknown. My favorite video of all time on YouTube is this one, where Carl Sagan, (the mister rogers of science), calmly and gleefully explains ways to visualize the 4th dimension. It made me realize that we do not just HAVE shadows, but we ARE shadows of a higher dimension. How exciting!Â
