In 1996, Alan Sokal submitted an article to Social Text, an academic journal of cultural studies. The article, "Transgressing the Boundaries: Towards a Transformative Hermeneutics of Quantum Gravity", was published in the journal. It proposed that quantum gravity is a social and linguistic construct. The journal did not practice academic peer review and it did not submit the article for outside expert review by a physicist. Three weeks after its publication. Sokal revealed that the article was a hoax.
