О курсе

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.

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.

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!

I loved every part of this course, especially how clearly everything was explained. I also really loved the annimations, design and little props that were used to explain things more clearly. I really feel like I'v learned so much and am actually a little bit sad that I'm finished. Thanks for the wonderful oppertunity to learn about something so fascinating!

I am truly delighted for a very high quality course about black holes. No doubt more will rapidly be learned in the near future about them. I would love to come to Alberta and help make the next updated revision with you. University of Alberta has the best quality and most interesting topics. Black holes are amazing and wonderful things to contemplate. Great work by a great team, the Black Holes 101 course makes me want to learn more.

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.

Great pace and great teachers! Would have loved more math-based problems to practice the formulas and calculations, but that's just me. A must-take course if you're starting out on your quest to understand the Universe.

With professors who can shrink astronomical distances and explain concepts in time, space and cosmology with such lucidity and more importantly joy, this course was bound to be one ,which in literal sense, has transformed the black hole into a living vibrant entity. The team has rekindled the joy of learning in me and am sure in all students. Heartfelt thanks .

Very interesting course. Between the colourful backgrounds of the speakers, simple imagery and the food analogies, they made astronomical theories and evidence much easier to understand for those who do not come from a physics background. Perhaps minor issues here and there with sound and when the speaker was not looking directly at the screen it could be a little off-putting, but other than that, it was an amazing course. I come from a biological sciences background (specifically health sciences) and I found this quite easy to understand. Tests were also fair as they were based on theories and confirmed evidence rather than equations, and weren't too difficult if you paid attention to the videos. Even if you didn't 100% understand a concept, the images presented to you stick quite well in your mind to the point you are able to answer the test questions easier. Coming out of this, I now have a greater understanding of some of the greatest physics concepts from Newton, Einstein, and so on. I have also expanded my knowledge of astronomy and the universe, as I have been studying it since I was a little girl, but was unfortunately able to pursue it due to my strong dislike for physics (you know, boring plain Earth physics). This helped me to continue on my passion for astronomy while also avoiding those icky physics courses. Thanks to the UofA and their group of astronomers for putting this together for anyone needing their astronomy fix.

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