Our Perspective Would Change at the Extreme Limits of Scale

Sometimes we ponder the infinite size of the cosmos and think about how insignificant we and all our problems are. Will we ever travel beyond our physical limits? But that's all relative. If we were to shrink down to an exponentially smaller size, we would be in a whole different universe, where we will never move beyond our physical limits even if they are the size of a small patch of lawn. We might escape human world problems, but we would encounter other problems dealing with physics and the influence of the wider world that microscopic life can never even perceive. As mind-blowing as that is, this video from Kurzgesagt takes us down to exponentially smaller sizes to see what those worlds are like.

While we are sure to learn something new about the physics of the tiny worlds around us, it also might remind you of the kinds of things you ponder during a psychedelic experience (or is that just me?). Once we are back to our normal scale, you can't help but think about the parts of our universe that are so large we cannot imagine them while we inhabit the world we know. What if some intelligent life form were experimenting with us right now, but we could never detect it because they are  bigger than our known universe? In other words, size matters.

The main video is only a little over ten minutes long, the rest an ad, although an interesting one.
