Quantum Experiment Breaks Reality By Seeing Two Versions Of Reality Existing At The Same Time

We are aware of how skewed our perception of reality is. How we see the world is shaped by our senses, our societies, and our knowledge. And you may want to rethink your belief that science will always provide you with an objective reality. Physicists may now verify a hypothesis that Nobel Prize winner Eugen Wigner initially put out in 1961. The setting of the experiment, dubbed "Wigner's Friend," is not too difficult. You begin with a quantum system that is in superposition, which implies that both of its states exist concurrently up to the point of measurement. In this illustration, the polarization (the axis on which a photon spins) is both horizontal and vertical. When they measure it, the system will collapse and the photon will be stuck into one of those two states. Wigner's buddy is in the lab doing the experiment. However, the quantum system—which, crucially, also includes the lab—remains in superposition for Wigner, who is outside the lab and uninformed of th...

This Game Lets You Build Or Destroy Your Own Solar System

If you've ever thought that just how clever you might be at planning a solar system, here's your chance to try skills. A new game allows you to construct a solar system, and then see it in act. This game is the work of Stefano Meschiari, a postdoctoral colleague at The University of Texas at Austin in the McDonald Observatory. Equally a student, he worked on Systemic Console, a presentation intended to deal with the data from real-life planets, the procedure of which stimulated the game.

Chinese Physicists Measure the Speed of Information Transfer in Quantum Entanglement

A team of Chinese physicists are performing some serious experiments and making a lot of advancement in the field of quantum mechanics. This team recently has tried to measure the speed of quantum entanglement- more demonstratively known as “spooky action at a distance”, as Einstein called it. The easy and technical definition of Quantum Entanglement could be: “Quantum entanglement arises when particles such as electrons, photons, molecules as large as buckyballs, and more likely even small diamonds interact physically and then become unconnected; the type of contact is such that each resultant member of a pair of particles is accurately designated by the same quantum mechanical state, which is unfixed in terms of important factors such as polarization, spin, momentum, position, etc.” Information in quantum entanglement transfers very fast and when most people describe this fascinating process, they’ll describe the information transfer as ‘instantaneous’ or ‘near-instanta...
