How to understand Einstein's equation for general relativity
The Einstein tensor is a fundamental concept in general relativity that combines the Ricci tensor and scalar with constants and the metric. The "Weyl" part is shape-distorting but plays no role in the Einstein field equations. There are 16 equations that describe how spacetime curvature relates to matter and energy, but they can be simplified to 10 independent equations using symmetry properties. The theory also has conserved quantities like energy and momentum. General relativity is a nonlinear theory, meaning solutions cannot be combined linearly, making it difficult to solve problems exactly. The text also discusses the cosmological constant and its role in general relativity, as well as the challenges of unifying gravity with quantum mechanics.
