You beat me in posting this (I searched for "CGP," first — you mispelled so I didn't see your comment). ---- My favorite CGP Grey video is Metric Paper... , which explores the vast (but limited) world we live in, from plancs to observable universe.

Read original comment ↗CPG Grey has a video [0] that goes into some, let's just say deeper , detail into metric paper that is well worth a watch if you haven't seen it. 0: [VIDEO]

Read original comment ↗I think this Zoom in/out physics story has pretty widely been told. Here is one by CPG Grey: [VIDEO] I like the one OP linked here. All the objects being clickable with a little description is nice
