 Mass in general relativity

In general relativity, mass plays a crucial role in the way matter and energy interact with the curvature of spacetime. However, the concept of mass in general relativity is more complex than in Newtonian physics. Here are the key points to understand about mass in the context of general relativity: 1. **Mass-Energy Equivalence**: According to Einstein's famous equation \(E = mc^2\), mass and energy are interchangeable.
