General relativity is extremely accurate for large things. Quantum theory is extremely accurate for small things. However, these two theories are incompatable - for example, trying to describe the inside of a black hole (small volume with large mass), which requires both theories at the same time, leads to nonsense. String theory is an attempt to reconcile this difficulty.
