Final answer:
The general theory of relativity, proposed by Albert Einstein, may need to be refined because it is currently incompatible with certain phenomena and laws. One example is the behavior of extremely large gravitational fields, such as those near black holes. General relativity also explains deviations in the orbit of the planet Mercury.
Step-by-step explanation:
The general theory of relativity, proposed by Albert Einstein, may need to be refined because it is currently incompatible with certain phenomena and laws.
One example of a phenomenon that general relativity does not fully explain is the behavior of extremely large gravitational fields, such as those near black holes. Einstein's modification of Newton's law of gravity in general relativity is most noticeable in these extreme conditions.
Additionally, general relativity also explains small but long-known deviations of the orbit of the planet Mercury from classical predictions. These deviations provide further evidence that general relativity may need to be refined.
