Boltzmann brain (Wikipedia)
The Boltzmann brain thought experiment suggests that it might be more likely for a single brain to spontaneously form in a void, complete with a memory of having existed in our universe, rather than for the entire universe to come about in the manner cosmologists think it actually did. Physicists use the Boltzmann brain thought experiment as a reductio ad absurdum argument for evaluating competing scientific theories.Schrödinger’s cat (Wikipedia)
In quantum mechanics, Schrödinger’s cat is a thought experiment concerning quantum superposition. In the thought experiment, a hypothetical cat may be considered simultaneously both alive and dead, while it is unobserved in a closed box, as a result of its fate being linked to a random subatomic event that may or may not occur. This experiment viewed this way is described as a paradox. This thought experiment was devised by physicist Erwin Schrödinger in 1935 in a discussion with Albert Einstein to illustrate what Schrödinger saw as the problems of the Copenhagen interpretation of quantum mechanics.- A thought experiment is a hypothetical situation in which a hypothesis, theory, or principle is laid out for the purpose of thinking through its consequences.
- Absurdist fiction (Wikipedia)
Absurdist fiction is a genre of novels, plays, poems, films, or other media that focuses on the experiences of characters in situations where they cannot find any inherent purpose in life, most often represented by ultimately meaningless actions and events that call into question the certainty of existential concepts such as truth or value. In some cases, it may overlap with literary nonsense.
