viXra

viXra is an electronic e-print archive known for unorthodox and fringe science. It was set up by independent physicist Philip Gibbs as an alternative to the dominant arXiv service operated by Cornell University. Its name comes from arXiv spelled backwards.

== Description == Although dominated by physics and mathematics submissions, viXra aims to cover topics across the whole scientific community. It accepts submissions without requiring authors to have an academic affiliation and without any threshold for quality. The e-prints on viXra are grouped into seven broad categories: physics, mathematics, computational science, biology, chemistry, humanities, and other areas. Anyone may post anything on viXra, though house rules do prohibit "vulgar, libellous, plagiaristic or dangerously misleading" content. As a result, the site has a reputation among physicists for hosting "material of no interest". Physicist Gerard 't Hooft writes, "When a paper is published in viXra, it is usually a sign that it is not likely to contain acceptable results. It may, but the odds against that are considerable".
