I came across a theory called "timescape" cosmology. If I understand the theory correctly it assumes that the universe is not homogenenous due to the large voids and gravitationally bounded system. Also time would be different for the observers on these two different locations.

1- Is CMBR and supernova datas support these ideas ?

2- It seems that the model contains different density parameters, Is this plausable ?

3- I am thinking that LCDM calculations makes some predictions and then we put some values of denisty parameters to match it with the CMBR data. And by doing that we find the actual values.

So is this the real process ? By changing the density parameters we can still fit our data to the CMBR data ?

Here are some links to the model
