Rob: Therefore, a true replica of the universe can never be made. However, it can be made so big that we would never notice that it is finite. Or the boundaries can be programmed to annihilate anything that comes into contact with them. Like antimatter for example.
Seth Lloyd at the Massachusetts Institute of Technology has suggested that the alterations in the mass of information has increased with 10120 since the big bang. This means that we will never be able to make computers fast enough to simulate the whole universe. Bostr?m claims that this may not be necessary. Instead of creating billions of galaxys, the programmer could deliver small realistic lightobjects to the simulated people. They would then not question the emptiness of the simulated world.
Robotscientist Hans Moravec at Carnegie Mellon University believes that in 30 years we will be able to simulate worlds with conscious life. If that proves right, then we can truly begin to wonder if we are victims of simulation or if we are exploiting innocent simulated lifeforms. Or both.
