nearing the speed of light, information appears to travel backwards in time.
A technological singularity is a hypothetical event
occurring when technological progress becomes so rapid that it makes the future after the singularity qualitatively different and harder to predict. Many of the most recognized writers on the singularity define the concept in terms of the technological creation of superintelligence, and allege that a post-singularity world would be unpredictable to humans due to an inability of human beings to imagine the intentions or capabilities of superintelligent entities
Critics assert that no computer
or machine will ever achieve human intelligence, while others hold that the definition of intelligence is irrelevant if the net result is the same
Isaac Asimov's Three Laws of Robotics
- A robot may not injure a human being or, through inaction, allow a human being to come to harm.
- A robot must obey orders given to it by human beings except where such orders would conflict with the First Law.
- A robot must protect its own existence as long as such protection does not conflict with either the First or Second Law.
A computer simulation may have voids
or other errors that manifest inside. As a simple example of this, when the "hall of mirrors" feedback loop effect occurs between a computer monitor and camera, the computer attempts to display "nothing" and fails in its attempt to do so. If a void can be found and tested, and if the observers survive its discovery, then it may reveal the underlying computational substrate. However, lapses in physical law could be attributed to other explanations, for instance inherent instability in the nature of reality.
Simulated reality
is the proposition that reality could be simulated—perhaps by computer simulation—to a degree indistinguishable from "true" reality. The Simulation Hypothesis is an example of a skeptical hypothesis, a proposal concerning the nature of reality put forward to question beliefs.
A black hole is a region of space-time
from which nothing, not even light, can escape. It is the result of the deformation of spacetime caused by a very compact mass. Around a black hole there is an undetectable surface which marks the point of no return. This surface is called an event horizon. It is called "black" because it absorbs all the light that hits it, reflecting nothing.
