Quantum entanglement does not actually allow for faster-than-light communication or violate the speed of light as a universal speed limit. Although the concept of entanglement can seem counterintuitive and has been described as "spooky action at a distance" by Albert Einstein, it does not enable information or signals to be transmitted faster than light.
Quantum entanglement refers to a phenomenon where two or more particles become correlated in such a way that the state of one particle is dependent on the state of another, regardless of the distance between them. When particles are entangled, measuring the state of one particle instantaneously affects the state of the other, even if they are separated by vast distances.
However, it's important to note that this instantaneous correlation does not allow for the transfer of information faster than the speed of light. The reason is that the act of measuring one entangled particle does not transmit information or enable communication between the particles. Even though the change in one particle's state appears to occur instantaneously, it cannot be used to transmit meaningful information in a way that violates the speed of light.
The speed of light in a vacuum, denoted by "c," is considered the universal speed limit because it represents the maximum speed at which information can travel through space. According to Einstein's theory of relativity, no information, energy, or material object can exceed this speed limit. While quantum entanglement may exhibit non-local correlations, it cannot be used to send signals faster than light, and therefore it remains consistent with the idea that light is the universal speed limit.
