| dc.description | Following our result that for the final state of continued spherical gravitational collapse, the gravitational mass of the fluid, $M_f\to 0$, we show that for a physical fluid the eventual value of $2GM_f/R_f\to 1$ rather than $2GM_f/R_f <1$, indicating approach to a zero-mass black hole. We also indicate that as the final state would be approached, the curvature components tend to blow up, and the proper radial distance $l$ and the proper time $τ\to \infty$. This indicates that actually the singularity is never attained for the collapse of an isolated body. We also identify that, the final state may correspond to the local 3-speed $v\to c$, eventhough the circumference speed $U\to 0$. However, at a finite observation epoch, such Eternally Collapsing Objects (ECOs) may have a modest local speed of collapse $v \ll c$, and the lab frame speed of collapse should practically be zero because of their extremely high surface gravitational red-shifts. | |
