SUMMARY
The virial theorem is not applicable to the majority of galaxy clusters due to the insufficient number of member galaxies, which hinders effective mass calculation. This conclusion is supported by a 1983 article by Marc Davis from UC Berkeley published in the Astrophysical Journal. While the virial theorem fails in this context, galaxy masses can still be estimated using their rotation curves. This distinction is crucial for astrophysicists studying galaxy dynamics.
