What is general relativity?
General relativity is Einstein’s theory of gravity, describing gravity as the curvature of spacetime caused by mass and energy.
Do I need to know special relativity before studying general relativity?
Yes. A foundation in special relativity is highly recommended, since general relativity extends its ideas to gravity and curved spacetime.
What mathematics is needed for a general relativity course?
Most courses require multivariable calculus, linear algebra, differential equations, and introductory tensor calculus.
What are tensors in general relativity?
Tensors are mathematical objects used to describe physical quantities independently of coordinates, including the spacetime metric and curvature.
How does general relativity explain black holes?
It predicts that sufficiently compact mass can curve spacetime so strongly that an event horizon forms, beyond which light cannot escape.
What are gravitational waves?
Gravitational waves are ripples in spacetime produced by accelerating massive objects, such as merging black holes or neutron stars.
How is general relativity used in cosmology?
General relativity provides the equations used to model the expansion, structure, and large-scale evolution of the universe.
