- That's true, but it's certainly possible. Shortly after GR, the
- Kaluza-Klein theory introduced a 5th dimension to describe EM forces.
- The idea was, that this extra dimension was shrinked, just as the extra
- dimensions in string theory. The biography from A. Pais over Einstein
- gives an short explaination of the Kaluza-Klein theory.
-
- This theory is not further developed because the problems which arose
- in quantizing them, the same problem we're facing now with GR.
