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....

Great course, I thoroughly enjoyed it and learned a lot. The graphics and illustrations were fun and informative, and I also enjoyed the food scenes - helped stick it in my memory. Thanks much!

I enjoyed the course. It covered all the areas necessary to understand black holes and the physics behind these mysterious phenomena. It was enjoyable and entertaining as well.

At the outset I sincerely thank Dr Sharon Morsink, Dr Jeanette Gladstone, Curtis Brown, Dr Ross Lockwood and Mr Stephen Lane for their excellent lectures and videos. All of you have guided me wonderfully to understand and pass the course on Black Holes. I am a retired Senior Manager in a Bank and am presently staying in the city of Visakhapatnam, India. Though my line of job is different, I have been very curious and highly interested to learn about the space, stars and Astronomy which is a very vast subject.

All your lectures are highly useful. I am planning to go through all the 10 modules of the course again and again to be thorough and not to have any doubt. I wonder if I can have access to the material even after receiving the Certificate. Due to some technical problem in my Laptap, I could not download any of your video lessons but I could only copy the printed lessons. Hence I am requesting to have access to any of your video lessons of this course.

I will be thankful if you can inform whether the Certificate will be sent by Airmail or to my email and if so how much time it may take.

I thank all my teachers and experts once again.

With regards,

Learned a lot about black holes which weren't even mentioned in my astronomy books when I first started being interested in astronomy when I was a boy as my dad (a former RAF navigator taught me to find my way round the sky) Interestingly enough the clip of the train demonstrating the Doppler effect was shot at Brandon - one of his "targets" during his training a Rivers Manitoba in 1942!

A great course which really stimulated the old grey cells and as far as I can say to be highly recommended!

Almost perfect. 1 lecturer absolutely natural delivery, main lecturer ok, 2 lecturers need more rehearsal, but not everyone is smooth in front of a camera. Course could stand to have a little better constructed quiz questions, add more than just multiple guess, and could stand to have an exam at the end. Course has the right amount of maths, as "Physics" is not in it's title. Concepts are well presented and illustrated. Nicely done! P.S. JJDrek is NOT Star Trek.

One of the best courses on Coursera about Astronomy. Super exciting! Great lectures, amazing science about the mysterious and fascinating black holes and not too impossible quizzes (unlike other Astronomy courses here in Coursera that have impossible quizzes). A fascinating journey into the most fearful spots of the Universe. Thanks a lot. Many greetings from Spain / Antonia

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.

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 gained more insight into the physics of black holes, stars and galaxies alike. This class was my favourite class and I can't wait to enroll into more of this university. Special thanks to the amazing and charismatic teachers, I especially like the many food analogies!
