A little clarification.
What i mean is that if 2 people are in deep space moving toward each other, any of them can claim, that they are standing still, and the other person is moving. This holds true, no matter how many people are watching each other, as long as nobody is accelerating.
This way, it may seem that 2 persons are moving with the speed of light, if you are passing by at that speed ( still in deep black space ). But for the 2 persons moving at the same speed, it will seem to them that the 3. person is moving at the speed of light, and they themselves are standing still. Becuase they are standing still, they will be able to throw a ball between each other ( Given dexterity and eye-hand coordination
). But because of the huge relative speed difference between the 3. person and the 2 persons playing ball, what time the persons catch the ball, will be different between the couple and the 3. person.
And now for something completely different.
With information, it is meant that you will be able to influence anything a distance away, say sending a bit to a computer, speaking to a person or throwing a ball. A concept, called radii of operation, is used to desceibe, how far away you will be able to do something, within a given time. This sphere is limited by the speed of light.
This means, that although you can "teleport" particles ( when entangled ), you won't have any influence on what kind of state the other ( here photon pair ) particle will have. It will in essence be a statistical measure, that will specify, what the properties of the particle pair will be; they will still be identical though.
This means, that you can't tell anybody anything on the recieving end. All they will get is static, and this will uphold the law that information can't travel faster than light. You will not be able to influence the particle outside you sphere of influence, but only measure what state it already had.
Some of the terms might not be right, but most of the theory should be. Please correct me if I'm wrong.
