Introduction: How much we don't know about the Universe.

This video presents motivation for the course, by explaining how much we do not know about our Universe.

“I know that I know nothing” – Socrates

Many years ago, people have different concepts about our Universe. For instance, various mythologies from different countries (e.g. India) had believed that our planet Earth is supported by elephants which are on top of a huge “world turtle” surrounded by a snake (need references). Now, we know that Earth is part of the Solar System together with 7 other planets, and in addition, we also got to know that our universe is composed of “invisible” dark matter and dark energy, things that are yet to be discovered in the future. Just like what the famous philosopher Socrates said, “I know that I know nothing”, we have so much to unravel about our Universe, and our natural curiosity to know the unknown have always been our main driving force in studying what lies beyond our current human understanding.

The video covers briefly the things that we already know about our Universe, and the methods used to understand them. However, our main focus is to talk about the things that we still don’t know about our Universe. Our main goal in this class is not only to inform, but also to invoke thinking and curiosity, as that will be our important step in learning the mysteries of the Universe.
