Accordingly, physicists to date have been unable to observe directly any singularity. C. It is specifically this startling phenomenon that has allowed us to codify the scant information currently available about singularities. D. Moreover, the existence of this extraordinary phenomenon is implied in the extensive reports of several physicists. E. Although unanticipated, phenomena such as these are consistent with the structure of a singularity.
