Next, as I was listening to another science show for here in the states, the host said what I thought was a terribly wrong statement. He first talked about hos it takes something like 17 minutes for our communications signals to reach Mars and vice versa. This is true and makes perfect sense, based on the speed of light.Then, however, he went on to say, in a hopeful kind of tone, that we would eventually be able to cut down this time to the point where there would be almost no time delay and we could control robots simultaneously with their actions.
Faster than light communication may be possible through quantum entanglement, albeit, not directly through the entangled particles themselves.

What was meant by the statement was that if fusion stopped abruptly in the Sun, but it otherwise remained the same, the photons that had already been produced would continue to spill out for another million years or so because that's roughly (theoretically) how long they take, on average, to escape and then begin their journey to Earth.Chris
The measurement of the state of a particle in one position will cause a collapse of the wave function and determine the state of the particle in another position that was entangled with it...
DrB, you can determine the state, and therefore know what the other person will see, but you can't set the state to a required value. In this respect, the state can be used to decide an action to be taken, and people at both ends of the entanglement will know what action has been taken without the need for a classical channel, but neither end can choose what action is taken.
i dont think so. coz then u have to communicate in the form of light waves instead of sound waves which means ur larynx is producing light . second even if it is the cause and u put a light wave reciever bypassing the ear and the vibrating tympanic membrane still the nerves will take a time of 240 km/hrs. so ultimately u will lag a little with in terms of light is too much.
