=Topic description=
General relativity (GR) is an advanced topic within the department of Astrophysics and requires a high level of knowledge in [[Calculus|calculus]], [[Portal:Algebra|algebra]] and [[topic:physics|physics]] in general. Tensor fields are a critical part of general relativity.

==Prerequisites==
* [[Portal:Special relativity|Topic:Special relativity]] (SR) - the spacetimes of GR have the spacetime of SR as a limiting case at a point in spacetime, so you must first understand SR
* [[Topic:Differential geometry]] - you need to understand tensors, tensor fields and differential geometry in general in order to understand GR; elements of these are frequently taught within a GR course as an alternative to a full differential geometry course

==Courses==
* [[Special relativity and steps towards general relativity]] (''shortcut:'' '''SRepsilonGR''')
** this course includes a few elements towards elementary general relativity
* [[Cosmology]] 
** twentieth/twenty-first cosmology is one of the main applications of general relativity

==Lectures==
*[[General relativity]]
*[[Introduction to general relativity]]
*[[Inveiling the breakdown of Euclidean geometry in linearized general relativity]]
