Informações sobre o curso

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....

Thank you for this course. Had a great time and learned lots of new and interesting stuff. cheers ^_^ (too much food references, though :D)

Un excelente curso. Un curso muy actualizado con recientes descubrimientos, pero que explica muy bien los principios físicos involucrados con la formación y desarrollo de los agujeros negros. Una excelente combinación de exposiciones de 4 excelentes profesores que exponen muy bien los principios. Un curso que trasmite lo que conocemos pero también lo que desconocemos de los agujeros negros, explica muy bien como los científicos desarrollan teorías y las pruebas por medio de la observación rigurosa. Felicitaciones.

very best course that I have seen

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.

I loved this course, and I grew to absolutely adore the instructors. It's readily apparent that they had fun putting it all together. And the production staff! How fun were the animations, graphics, live shots and edits? All the way fun! Thanks everyone! The only problem with this course? Astro 105, 201, 314 and higher level specialities aren't yet available. More U of A Astrophysics courses, please. You guys rock.

Very simple course, but in not mathematical words explain, how to born, live and died Black Holes.

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.
