Einstein's Equations for Strings in Space Time

Einstein's equations are the first correction to these consistency conditions for strings propagating in space time. The string length is extremely microscopic d and so the string length divided by the radius of curvature is a tiny, tiny number. In nature, this is a really good approximation in undermost circumstances. So we have to revive this caluticline idea in order to accommodate what strength theory wants a space time to be.
