This Video features Travelling The Black Hole explained in scientific astronomical facts. A lot of scientific facts and terms such as "Shwarzschild radius", "singularity", "gravitational lensing", "photon sphere", "spaghettification", "wormhole", "cosmological principle", "dumbhole" and "Googolplex". Basic knowledge in science, astronomy and physics are required to further understand the content of this video.
I would like to describe this video presentation as cognitive learning instructional design. The lecturer give us a simple analogy for each new concept introduced before moving on to the complex ones. The video has its strong points, listed below:
1) Clear, word by word explanation which helps a non native English speaking student to understand
what is being relayed
2) Explanation is done from simple to complex
3) Scientific terms are spelled out during the explanation
4) Graphical examples and video simulation further help in understanding the complex concept being
explained
There are however, a few improvements that enhance this video presentation, probably an engaging space sound music. As for the introduction of new scientific terms, I think it would further help if the definition, instead of just being explained, can be defined in words on screen. To me, it will serve as a reinforcement of what that has been heard.
