The possible violation of the weak cosmic censorship hypothesis in astrophysical phenomena can provide us with information about trans-Planckian physics through observations. We present negative evidence, however, that one should not expect such a possibility at least when the deviation from spherical symmetry is negligible and the parameter values of collapse are astrophysically reasonable. Taking the Lema tre-Tolman-Bondi solution as the model most likely to counter the weak hypothesis, we show that the mass (greater than or similar to 1.5 M-circle dot) and density (greater than or similar to 1.5 x 10(15) g/cm(3)) of the collapsing object produce a gravitational field strong enough to capture any null rays soon after emanating from the singularity.
