Multiple Dimensions – How can we even think about them?
Professor Nigel Ray from Manchester University explored with us what it means to have many dimensions as many current theories of Physics seem to demand. How can you travel in a direction which is not forward nor back nor up nor down nor left nor right but is at right angles to all those directions even if you are a fundamental particle? What do we mean when, like Einstein, we say that space is “curved”? How can “nothing” or a vacuum be curved? It’s difficult to get your mind round it and Professor Ray will help us do just that. Following on from our Quantum Mechanics and Relativity sessions, Professor Ray will help us feel more comfortable with some of the basic but weird concepts involved and show how just by being normal but having an extra dimension any creature would have Godlike powers over lesser dimensional creatures.
