Abstract:
Quantum mechanics is very succesful in the description and prediction of the microphysical world. So nowadays very few doubt its authenticity. Nevertheless, there are some conceptual issues that are still under debate, such as action at a distance. It took a while after the introduction of the EPR paradox in 1935 until John Stewart Bell derived an inequality, using local hidden variables. This inequality was in contrast with predictions of quantum mechanics. Experiments also contradicted this inequality. This implies that there is action at distance which, in turn suggests, the violation of the special relativity. In this thesis, we consider this issue and shall see that on the one hand we can consider quantum mechanics and special relativity in peaceful coexistance, but on the other hand considering the issue in a closer look, we find that this hidden contradiction can not be resolved. There is, however, a possibility that these two theories are emergent from a more fundamental theory which describes nature in a more profound way
