With this assumption, empty space automatically has de Sitter symmetry, and what would normally be called the cosmological constant in general relativity becomes a fundamental dimensional parameter describing the symmetry structure of spacetime.

In 1972, [[Wikipedia:Freeman Dyson\|Freeman Dyson]] popularized it as a hypothetical road by which mathematicians could have guessed part of the structure of general relativity before it was discovered.<ref name=dyson>		First proposed by [[Wikipedia:Luigi Fantappiè\|Luigi Fantappiè]] in 1954, the theory remained obscure until it was rediscovered in 1968 by [[Wikipedia:Henri Bacry\|Henri Bacry]] and [[Wikipedia:Jean-Marc Lévy-Leblond\|Jean-Marc Lévy-Leblond]].
