The Challenge of Uniting Quantum Mechanics and Theory of Relativity

Uniting quantum mechanics and theory of relativity is a challenge that scientists are trying to solve. One approach is to use quantum mechanics in curved space, which works for particles moving in curved space but not for showing how quantum mechanics can make space curved. Gravity is difficult to calculate with because gravitons emit more gravitons, making it quickly become uncontrollable. Another approach is to quantize space itself, but so far, no one has been able to mathematically bring these two theories together. The search for a mathematical description that explains the universe and makes sense is linked to the theoretical and philosophical implications. Scientists wonder how far they need to go to make a comprehensive theory and whether they should start from something else to explain what is observed on a larger scale.
