11/8/2023 0 Comments Quantum physics 101![]() ![]() To illustrate this point, he and two of his collegues, Boris Podolsky and Nathan Rosen, created an infamous thought experiment that he hoped would debunk one of the central tenants of quantum mechanics.Īccording to Einstein's relativity theories, absolutely nothing can move faster than light. For Einstein, the idea that there were things in nature that could never be measured, known, or precisely predicted was pseudoscientific nonsense that went against the core precepts of science as he understood it. His biggest stumbling block was quantum mechanics, a new branch of theoretical physics at the time which postulates that, at the smallest of scales, the physical universe is ruled over by probability and indeterminacy. In order to grasp why we should pay attention to proposals like Ursin's (and why people should support them), let's take a step back and look at the history of the entanglement conundrum.Īs he approached the end of his life, Albert Einstein struggled to come up with a Grand Unified Theory of Physics that would sufficiently describe the physical universe and the forces that control it. This may not sound important, but it is, because the nature of quantum entanglement remains one of the greatest enduring mysteries of science. This would be the greatest distance at which quantum entanglement has been practically tested, and could thus provide some insights into how it works. ![]() ![]() In a proposal today in the Institute of Physics and German Physical Society's New Journal of Physics, physicist Rupert Ursin of the Australian Academy of Sciences, along with colleagues, suggests sending half of an entagled pair of particles to the International Space Station in order to test quantum entanglement at a distance of roughly 400 kilometers. ![]()
