Project description

Collapsing Cosmology Research Utilities

The collapse package contains utilities for computing symbolic and numerical expressions related to the time evolution of collapsing cosmologies.

The collapse package makes use of sympy to compute symbolic curvature equations (EFE). Specific Details

# Load the predefined FLRW metric
from collapse.symbolic import metric, gravity
flrw = metric.flrw_metric().subs({'c': 1})
flrw

efe_00 = gravity.einstein_equation(0, 0, flrw).doit()
efe_00

# Can simplify notation using "dots"
metric.simplify_deriv_notation(efe_00, flrw, use_dots=True)
