I'll point you here on the topic of the cluster speed https://ui.adsabs.harvard.edu/abs/2007MNRAS.380..911S/abstra... I.e. it's not a problem.


ok that's fine but it still doesn't change the fact that there is a distinction between parameterizing field vs parameterizing the simulation. You shouldn't have conflated the two in your defense of LCDM.


What exactly are you talking about with "parameterizing field" and a couple comments up and "the lambda-cdm field" (emphasis yours) ?

Are you referring to the Friedmann equations? The equation of state? The half-dozen free parameters of the model itself?

What's your exact objection here? Because there isn't anything that I would quickly call a "lambda-cdm field" in the standard model of cosmology any more than there is a single "standard model field" in the standard model of particle physics.

"The field itself does" -- again, what exactly do you mean here? Are you even talking about a mathematical or even physical object?

sorry, it's been about 20 years since I've done astrophysics.
