        The `collapse` package contains utilities for computing symbolic and numerical expressions related to the time evolution
        of collapsing cosmologies. 
        
        
        ## Symbolic Tools
        The `collapse` package makes use of `sympy` to compute symbolic curvature equations (EFE).
        [Specific Details](./collapse/symbolic/README.md)
        
        ### Example Computation: FLRW Cosmology
        
        ```python
        # Load the predefined FLRW metric
        from collapse.symbolic import metric, gravity, utilities
        flrw = metric.flrw().subs({'c': 1})
        flrw
        ```
