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....

The course was very interesting . I loved that the expainations used references to known movies and TV shows, it made the more entartaining and made me try to use the formulas I learned in real life.

Very happy with the course. A lot of information well presented, in an interesting way, by very knowledgeable professors. One observation, maybe one of them could make his presentations talking a little slower? I don´t think I have to give name? Thank you all!!!

I loved this course. It was quite challenging since some of the topics were complex but the professors did their best to explain them as easy as possible. I learned a lot of new information about black holes and find them even more interesting than before.

I completely completely loved the course ..It is by far the most organized and a wholesome experience of astronomy's introduction in a beautiful way...I love the feels like family already..

Thank you so much for the love and support Team

The complex almost irrational circumstances around black holes brought in a manner that is surprisingly clear and digestible. The world of black holes is after the course even more intriguing and fascinating. Triple A without a doubt.

Excellent cours. Clair, pédagogique. Les modules sont très bien structurés, en couvrant toute la matière des trous noirs. Félicitations à l'équipe de l'université d'Alberta. J'espère que cette équipe puisse présenter un autre projet !

Awesome course! Will teach you about black holes for sure as the name implies, but along the way you will also learn about, light, doppler shift, relativity, quantum mechanics and much more. Will build a basic foundation on physics.

This course does a fine job of explaining what was known of black hole physics thru 2017. Ligo information was not complete, with 4 years of observation missing. The staff was easy to understand and definitely knew their subject

It was great, the quizzes were perfectly fitted to the material, not too mathematically focused, great to spark a new interest in Astronomy! P.S Forum questions were answered in a nice amount of time too!

It's a really good course to learn more about black holes, that are really mysterious objects. Thanks to this course i could expand my knowledge about black holes. It's a really good course.

Outstanding use of graphics, formulas, exercises, real-word and fictional examples, and humour (especially with foods) to illustrate what could otherwise be overwhelmingly abstract concepts.

A very well prepared, organized and resourceful course. It really increased my knowledge about Black Hole, which otherwise would be too shallow for being taken from Google or internet only.
