In 1915 Einstein published his Theory of General Relativity - he had published his Theory of Special Relativity earlier but this general theory was more complex. In the 100 years since, mathematicians have worked on his theories and equations, working out solutions that even Einstein thought were impossible.
As technology moves on and space exploration reaches further and further out, Einstein's theories are being proven experimentally and by observation too.
We asked researchers - staff and students - to explain aspects of General Relativity for us, and also how they got interested in this area in the first place. We hope you find their answers enlightening!
