I am currently a student-teacher pursuing my teaching certificate for high school physics. Over the past month or so, my students have been asking a lot about black holes. Since they are showing such an interest in space, I thought it might be a good idea to find a video to show them to connect their interest in black holes with the material that we have been covering over the past several months. Does anyone have any recommendations for a video that would tie the concepts of black holes to physics? Thank you in advance.
