| | 320 | * Does their choice of periodic boundaries prevent gravity's strongest mode? The box is 5-10 Jeans lengths so it should globally collapse in 1 free fall time. Periodic boundaries == Fictitious dark energy... |

| | 327 | * Is it fair to assume that every cell that is denser then [[latex($8000 \rho_0$)]] will collapse? Or that every cell denser than [[latex($\rho_{cr}$)]] is surrounded by enough mass to collapse? [[latex($\rho_{cr}/\rho_0= .547 \alpha_{vir} \mathcal{M}^2$)]] so [[latex($8000 \rho_0 > \rho_{cr}$)]] for all the choices of [[latex($\mathcal{M}$)]] and [[latex($\alpha_{vir}$)]]. But numerous instabilities can destabilize the shocks before they have built up a thick layer of material... Especially the NTSI (Blondin & Marks 1996). It would have been instructive to have seen an IMF |
