We have learned a lot recently about how the Universe evolved in 13.8 billion years since the Big Bang. More than 80% of matter in the Universe is mysterious Dark Matter, which made stars and galaxies to form. The newly discovered Higgs-boson became frozen into the Universe a trillionth of a second after the Big Bang and brought order to the Universe. Yet we still do not know how ordinary matter (atoms) survived against total annihilation by Anti-Matter. The expansion of the Universe started acceleration about 7 billion years ago and the Universe is being ripped apart. The culprit is Dark Energy, a mysterious energy multiplying in vacuum. I will present evidence behind these startling discoveries and discuss what we may learn in the near future.
This course is offered in English.
Overview
Syllabus
- From Daily Life to the Big Bang
- Understanding the Universe in which we live and how to probe it can begin with simple daily life experiences such as night and day and the four seasons. Starting from these observations, we will take a journey from our local Earth at the present time all the way to the edge of the universe and back to its birth, learning the techniques and findings in modern physics that provide us this understanding.
- Birth of Elements and Higgs Boson
- We are made of chemical elements. So one of the fundamental questions “where do we come from?” leads to another question: “how were elements born?”. This is related to the Higgs Boson, an important particle in answering this question which remained elusive until its discovery was recently announced on July 4, 2012. In this module, we will learn recent research outcomes on these topics.
- Dark Matter and Anti-Matter
- In this module, we will learn about dark matter and anti-matter -- some of the more mysterious sides of the Universe. We know dark matter played an important role in the formation of stars and galaxies, but much of properties are still unknown to us. In another strange mystery, we will see how the beginning of the universe started with equal amounts of matter and anti-matter, yet somehow only matter (which we are composed of!) survived.
- Inflation and Dark Energy
- At the very beginning, the Universe exponentially expanded during a period known as the cosmic inflation. Recent studies suggested that the Universe has entered into another stage of expansion, considered to be caused by 'mysterious' dark energy. In this module, we will learn about inflation, dark energy, and the possible fates of our Universe.

through this platform, i know about the value of physics astronomically. Through this i came to know more about our big bang and the Dark Energy.
-
I'm quite attracted to physics and cosmology it helps me to understand and discover how the laws of universe work and how it has started.
From the creation of the universe to the first and last discovers .
Relativity ,dark matter ,wormholes, galaxies and the supernova, comets etc -
This course is great but it assumes high familiarity with high school physics and calculus to complete its advance track.
-
Prof. Murayama is a tremendous instructor and knows how to teach his discipline. Maybe the coursework had to be diluted in more weeks but it's still very recommended.
-
Short introduction to some elements of cosmology. Those who have already studied physics and astronomy may find it insufficiently challenging and too superficial.
-
This is a nice introduction to cosmological problems, but it's more of an advanced introduction, since it requires some knowledge of calculus, which is kind of expected for this field. The lectures deal with Higg's boson, dark matter and dark energy, and inflation, and the whole course can be done on a binge-watch Sunday if you have previous background in physics or mathematics. Too bad it's a self-paced course, I think I would have enjoyed it more if it were a live one. However, the instructor is nice, and the content is nicely organized as well, go for it.

Quite a lot has been learnt recently and this will probably need to be updated regularly
Quizzes were v tough for what is called a beginners class -
interesting class. I learnt a great deal. Problem sets have 3 levels of diffculty ranging from fundamental idea, to calculus based answers.
-
This was a wonderful course! The professor does a great job in turning difficult concepts more clear and easier to understand!
-
Lots of info about recent (10 years) discoveries and developments in the study of the Universe
