  The present paper proposes a new explanation for the 3-dimensional Einstein
general theory of relativity which is free of contradictions and consistent
with usual 4-dimensional physics. We discuss the property of the new gravity
theory with temporal scalar field arise in lower-dimensional theories as the
reduction of timelike extra dimension. These ideas we continued by using the
3-dimensional analog of Jordan, Brans-Dicke theory with temporal scalar field
where space and time are treated in different ways.
