When scientists began to study the smallest particles—atoms and their components—they discovered a world that breaks all known rules. One of the most mysterious phenomena in this world is quantum entanglement.
Quantum entanglement is a phenomenon in which two or more particles are so closely linked that a change in the state of one instantly affects the other, regardless of the distance between them. This means that if you have two entangled electrons separated by opposite ends of the universe, and you measure the state of one (for example, its spin direction), the state of the other instantly changes as well, without any signal being transmitted.
This phenomenon violates one of the fundamental principles of Einstein's theory of relativity: nothing can travel faster than the speed of light. In this case, according to the theory, information between two particles should take time to be transmitted so that their states can align simultaneously. But in entanglement, it happens instantaneously. Einstein, who also believed that information couldn't travel faster than light, called this phenomenon "spooky action at a distance" and tried to disprove it until the end of his life.
Yes, despite its improbability, quantum entanglement has been proven countless times through experiments. Physicists have been able to demonstrate it in laboratories, even with particles separated by thousands of kilometers. This fact not only revolutionizes our understanding of physics but also opens doors to new possibilities, such as quantum computing and communication.
Quantum entanglement is not just a scientific fact; it's a reminder that our universe is stranger than we can imagine. It seems to point to a deep interconnectedness of the cosmos, showing that even vast distances are negated at the smallest scale. This phenomenon has become a symbol of the connection between scientific physics and spiritual mysticism.
