Ansible
The ansible is a device for instanteneous communication over the vast distances of space. It was invented by Shevek of Anarres. When there is massage to be sent between two ansibles, one of them has to be in a fixed position on a body of a sufficiently large mass, e.g. a planet. The other ansible may be on another planet, a ship or anywhere. A ship travelling in NAFAL space cannot transmit; it has to slow down and enter the normal space-time first. The principle is that information is immaterial and therefore it does not have to follow Einstein's statement that nothing can travel faster than light. The principle has been discribed by an analogy: if you have a very, very long rod, and you move one end of it from side to side, then the other end moves too. It takes a lot of energy to send messages over the ansible, and so it's very expensive. Due to cosmic mass interference, the range is limited to approx. 120 light years. | ||||
