  This paper describes a 'New Formula' in place of Einstein's Famous Formula
(EFF) to provide the compatibility between the Special Theory of Relativity
(STR), black holes and strings. The 'New Formula' can also predict and describe
the space-time singularities without the distribution of mass and energy.
According to the 'New Formula', any particle can reach to and exceed the speed
of light. The EFF is only valid and applicable in the vacuum (the mediums which
have low current density: outside string, outside black hole), but is not valid
and applicable for inside string and inside black hole including space-time
singularities. However, the 'New Formula' is valid and applicable in all
mediums including inside string and inside black hole.
