About this 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....

Course covers all the bases, both from the very basic notions, with suitable introductory material on things like how one determines the composition of a star from spectra, to the physics that allows one to understand the recent image of a black hole(without this course one might think photographing a black hole to be impossible.We now understand the time dilation effects of approaching a black hole and how one can do so safely.

Fascinating stuff

I have just completed one module and besides black holes I have also learned other concepts for my general knowledge as to refresh concepts before proceeding to black hole. Way of delivering of instructors is very good as I thought I have known everything about respective topic.

Watching this course was a lot of fun. I was able to repeat things I already knew and learned even more new things. Because the way things are explained I was able to keep up until the end even if I didn't understand every single detail yet. This course is a really great way of learning about Black Holes.
