I Zero Active Mass in FRW cosmologies

[jcap]

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:

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)

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 I note that the paper has not been peer reviewed or published in a journal.

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 This paper also has not been peer-reviewed or published in a journal.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.
