Quantum entanglement also seems to contradict the belief of information limited to the speed of light.
According to the theory, if 2 particles are quantum entangled but at lightyears apart, if one of them gets measured and resulting state is negative, the other one is guaranteed to have a positive state. But given the fact that a quantum state of a particle is totally random before it gets measured, it means that the other one is also random.
So you have 2 particles with 100% random states lightyears apart, but when one particle is measured to have a given state, somehow the other particle immeadiatly is guaranteed to have the opposite state. While it takes years for the speed of light to communicate between the 2 particles.
