Calculation for an object moving towards a galaxy
This page gives the details of the calculation for an object with no internal forces moving from the origin towards a comoving galaxy in an expanding universe, as described in my paper
Expanding Space: Just say No
at quantropy.org.
The calculation is done using the
Euler Math Toolbox.
