No-go theorem

From Wikipedia, the free encyclopedia

In theoretical physics, a no-go theorem is a theorem that states that a particular situation is not physically possible. This type of theorem imposes boundaries on certain mathematical or physical possibilities via a proof of contradiction.[1][2][3]

Instances of no-go theorems

[edit]

Full descriptions of the no-go theorems named below are given in other articles linked to their names. A few of them are broad, general categories under which several theorems fall. Other names are broad and general-sounding but only refer to a single theorem.

Classical electrodynamics

[edit]

Non-relativistic quantum Mechanics and quantum information

[edit]

Quantum field theory and string theory

[edit]

Proof of impossibility

[edit]

In mathematics there is the concept of proof of impossibility referring to problems impossible to solve. The difference between this impossibility and that of the no-go theorems is that a proof of impossibility states a category of logical proposition that may never be true; a no-go theorem instead presents a sequence of events that may never occur.
