# The Origin of Gravitational Lensing: A Postscript to Einstein's 1936 Science Paper

@article{Renn1997TheOO, title={The Origin of Gravitational Lensing: A Postscript to Einstein's 1936 Science Paper}, author={J{\"u}rgen Renn and Tilman Sauer and John J. Stachel}, journal={Science}, year={1997}, volume={275}, pages={184 - 186} }

Gravitational lensing, now taken as an important astrophysical consequence of the general theory of relativity, was found even before this theory was formulated but was discarded as a speculative idea without any chance of empirical confirmation. Reconstruction of some of Einstein's research notes dating back to 1912 reveals that he explored the possibility of gravitational lensing 3 years before completing his general theory of relativity. On the basis of preliminary insights into this theory…

Gravitational microlensing favours a range of orbital separations that covers planets whose orbital periods are too long to allow detection by other indirect techniques, but which are still too close to their host star to be detected by means of their emitted or reflected light.
