Imagine being able to see light waves bouncing off objects, microscopic creatures in pond water, or watching a nano-machine destroy a cancer cell as if you could see your own hand. What could you study and learn from that observation? That’s the focus of ‘Mysteries of the Unseen World,’ a new documentary short by National Geographic. Narrated by Forest Whitaker and clocking in around 40 minutes, ‘Mysteries’ is like a refresher science class, covering just enough information to educate viewers and pique their interest.
