The three types of information that Tyson's essays use to convey ideas and messages about black holes are:
1. Language that draws the user into the topic.
2. Ability to interact with the information.
3. Metaphors that help the user understand the information.
Explanation:
Neil DeGrasse Tyson is a astrophysicist, but also a well-known science popularizer, which gives him the best of both worlds: on one hand, he can understand the scientific reason of the structure of the cosmos, and on the other hand, he has a skill for teaching others with simplicity those same complex reasons.
He normally gives lectures and conferences in which he effectively uses the option 5: Humor to engage the user, and he is very popular for making the audience laugh and enjoy his lectures, but in his essay does not use it as much. Otherwise, the option 3: Access to information through multiple senses, is not a type of information that represents his writing, for he uses more metaphors to explain something people can barely feel by their senses.
The essay in which Tyson convey ideas and messages about black holes is the one titled "Dead by Black Hole. And Other Cosmic Quandaries", published in 2007. This book is a compiled edition of some of his regular publications at the section Universe on the Natural History Magazine, that is aimed at general audience. So, his essay also has a purpose of explaining science to people that has little or no scientific background.
This is why is his essay, Tyson uses the option 1: Language that draws the user into the topic. The key basis of his writing is: using language that most people can understand, so that the audience can involve in the reading, for they are listening to familiar words.
Now, Tyson also uses the option 2: The ability to interact with the information. Based on that he is a scientist, he shows core theories and data to people, but not as isolated facts, instead he shows them with context, also make comparisons that can help catch the main implications. He interact with data so they mean something to the users.
And finally, the type of information that uses the most is the option 4: Metaphors to help the user understand the information. Tyson knows that he is explaining something that is not easy to understand, specially for people that does not have a scientific background, therefore he uses metaphors to make the information more understandable, for the metaphor is a figure of speech that explains one thing with another by the emphasizing the one thing the two things have in common. Tyson explain complex theories and data with day-to-day experiences by bringing out what they have in common.
