Zero Active Mass in FRW cosmologies

What do people think of Fulvio Melia's argument for the necessity of "zero active mass" in FRW cosmologies? (i.e. the overall equation of state must be ##\rho+3p=0## at all times)

Here is a link to an interesting lecture video:


Here is a recent paper:

Since ##\rho + 3p = 0## is obviously false in the universe now, whatever argument he is making is flawed.

Here is a recent paper
The abstract of this paper contains several obvious errors and misunderstandings. I note that the paper has not been peer reviewed or published in a journal.

A more relevant paper
Which still makes the same obviously false claim that ##\rho + 3p = 0##. This paper also has not been peer-reviewed or published in a journal.

The answer to your question is not going to change no matter how many papers by this author you find. Thread closed.
