What is the course about?
Although often considered the preserve of science fiction, parallel universes are permitted by some theories of physics, and may even be required under some interpretations of those theories.
Different theories actually imply different types of parallel universe, so we will consider what types of parallel universe there might be.
We will also consider some claims to have found experimental evidence of parallel universes, and how such claims are to be interpreted.
What will we cover?
1) The concept of the multiverse.
2) The types of parallel universe compatible with our theories of physics.
3) Assessing claims of physical evidence for parallel universes.
4) Arguments for and against the multiverse hypothesis.
What will I achieve?
By the end of this course you should be able to...
1) Explain the concept of the multiverse.
2) Recognise the types of parallel universe compatible with our theories of physics.
3) Assess the claims of physical evidence for parallel universes.
4) Describe the arguments for and against the multiverse hypothesis.
What level is the course and do I need any particular skills?
This course does not require any background in physics or mathematics. All the topics will be explained from first principles. At the same time, the topics covered will also be of interest to those who have already delved into this fascinating area of physics.
How will I be taught, and will there be any work outside the class?
The topics will be presented by the tutor with the aid of various audio-visual presentations such as PowerPoints and short video clips. We will discuss questions as a class as they arise. The materials presented will be available but you may wish to make your own notes. There will be no requirement for any work outside of class, although the tutor will be happy to discuss any related topics which you have considered.
Are there any other costs? Is there anything I need to bring?
No other costs. Pen and paper if you wish to take notes.
When I've finished, what course can I do next?

Dr. Gary Retallick Mathematics and Science Gary obtained his Phd in Philosophy of Physics from Kings College London in 2006. His thesis explored the physics of time, touching upon relativity, field equations, quantum mechanics, thermodynamics and metaphysics. Gary began his teaching career in computing, going on to teach philosophy for the WEA and Mary Ward Centre, and physics and mathematics at both Birkbeck College London and the Open University. He currently teaches various science related courses, spanning topics in physics, chemistry and mathematics, at City Lit. Languages - Cornish Aside from his career in Science, Gary has an ongoing interest in languages, in particular Cornish, the language of his ancestors. He began studying Cornish at City Lit in 1998, and after passing the grade three Cornish exam with distinction he started to assist his tutor, Jo P'rhys. After a number of years as language assistant to the class, Gary was formally appointed as teacher of the Cornish beginners class, allowing Jo to concentrate on the higher level classes. Gary now teaches both the beginners and lower intermediate classes.
