Branch Lecture: A Brief History of Gravity
The May IoP South Central Branch talk brings Prof Jim Al-Khalili, Professor of Physics and Professor of Public Engagement in Science at the University of Surrey to talk about the weakest of the fundamental forces...
At school we all learn about gravity as one of the fundamental forces of nature, described by Newton hundreds of years ago. Even Einstein, who went further by showing that gravity isn’t actually a force at all, but rather the shape of space and time themselves, didn’t really shake us from our cosy complacency. Well, things are coming to a head now. We still do not have a proper theory that connects gravity to the other three forces in the Universe. And gravitational mysteries like dark matter and dark energy have not yet been solved by physicists. We investigate black holes and gravitational waves, and study the origins and destiny of our entire universe, and yet there’s that nagging sense that something fundamental is missing from our understanding. Are we waiting for another Einstein to come along and point to a new idea? This lecture will survey our current state of knowledge.
