Query: Time-like singularities in General Relativity   We review the properties of naked time-like singularities in the General
Relativity and quantum effects in their vicinity. We demonstrate that only
line-like singularities can be formed by a collapse and are the only candidates
to break the Cosmic Censorship Principle.
