Ever heard of quantum entanglement? It is probably the most bizarre physical phenomenon in the quantum world, it can be two particles in a time faster than the speed of light, and according to special relativity, the limit of everything in the world is the speed of light, why can he exceed the speed of light? This even became a shadow of Einstein's later years, which Einstein called the "ghost effect of hyper-distance".
I believe that everyone has seen the world's first image of a black hole, but have you ever seen the world's first image of quantum entanglement? In the past ten years ago, the quantum entanglement effect was also the core content of research in the fields of quantum computing and quantum cryptography, but no one or instrument, including the United States, has ever been able to capture this "ghost image", but on July 12, 2019, the door of the quantum world was suddenly opened, and a team of physicists from the University of Glasgow in Scotland successfully captured the image after several years with the help of the most advanced nanoscale optical instruments. It is also the first time in the world that visual evidence of the phenomenon of quantum entanglement has been obtained.
The light and shadow of the rotating particles on the image shocked the physics community for a while, but only the picture can not let everyone understand what is the phenomenon of quantum entanglement, in fact, in simple terms, quantum entanglement refers to when the two examples form an inseparable correlation state, no matter where they are, no matter how far apart they are, once any change in one of the particles, it will affect another particle at the first time, this phenomenon is somewhat similar to telepathy.
Let's take a more popular example, suppose you and your girlfriend are a pair of entangled particles that have been each other for a long time, and you are far away in the Sagittarius Nebula, and he is far away on the moon. Without warning, you do not have any prior communication, you are suddenly your girlfriend to launch love in the air, then your girlfriend will also make the same action to you at the first time, and you will launch a few he will launch a few. The reflection of the two is "God synchronized".
With this popular and simple example, I believe that you should have a rough understanding of this phenomenon of entanglement. So after understanding the connotation of the phenomenon of quantum entanglement, we have to think about why this caused Einstein to overturn in his later years. What's so weird about quantum entanglement? We'll see you next time!
