About the Course

What is a black hole? Do they really exist? How do they form? How are they related to stars? What would happen if you fell into one? How do you see a black hole if they emit no light? What’s the difference between a black hole and a really dark star? Could a particle accelerator create a black hole? Can a black hole also be a worm hole or a time machine? In Astro 101: Black Holes, you will explore the concepts behind black holes. Using the theme of black holes, you will learn the basic ideas of astronomy, relativity, and quantum physics. After completing this course, you will be able to: • Describe the essential properties of black holes. • Explain recent black hole research using plain language and appropriate analogies. • Compare black holes in popular culture to modern physics to distinguish science fact from science fiction. • Describe the application of fundamental physical concepts including gravity, special and general relativity, and quantum mechanics to reported scientific observations. • Recognize different types of stars and distinguish which stars can potentially become black holes. • Differentiate types of black holes and classify each type as observed or theoretical. • Characterize formation theories associated with each type of black hole. • Identify different ways of detecting black holes, and appropriate technologies associated with each detection method. • Summarize the puzzles facing black hole researchers in modern science....

If time dialation is infinite at the event horizon, other than by the warping of spacetime itself, how could anything actually cross the horizon in less than infinite time?

Pretty decent course for an introductory level. However, the teaching assistants aren't that responsive so you got to wait a little longer. Overall a satisfactory course.

Lots of interesting information about black holes and ongoing research about them. Only very rudimentary math needed for the course.

It was a fun course, however it would have been more fun if there was more interactive stuff to do.

Fascinating. Plus they get into Star Trek. Pretty technical, though

I think the lecture should have pictures and colors.

This course is very well produced and interesting. However, it is not challenging enough. It should at least propose a weekly set of problems (possibly on a voluntary basis) requiring a modicum of physics and math skills. As it stands, it tells a pretty story but does not allow a student to grasp how the story was put together. I gained much information about BHs and other celestial objects, but zero new skill. In addition, I find that lecturers reading prompters make for lifeless presentations that are not clearly superior to being assigned to read a transcript or book chapter. I thought that the staff engaged very effectively with the students on the forum.

Oftentimes one gets the impression that some of the lecturers have no idea what they are talking about; they appear to be reading from scripts off their computers. I also have the feeling that the overall course can be more "instructive" if the material is organized differently. This is a class for novices, not for experts, and it may not be necessary for a course lasting "10 weeks" to give the novice a useful overview of the subject.

Im convinced some of the questions have all wrong answers regardless. Its a very detailed course which is good but found myself getting bored often.

A good course, with satisfactory content, good for physics undergraduate students and others fascinated by the beauties of the cosmos.

Too many instructors. Exams do not qualify what is taught. Poorly constructed.
