In science fiction, artificial gravity (or cancellation of gravity) or "paragravity"<ref>''Collision Orbit'', 1942 by [[Jack Williamson]]</ref><ref>''[[Pale Blue Dot (book)|Pale Blue Dot]]: A Vision of the Human Future in Space'' by [[Carl Sagan]], Chapter 19</ref> is sometimes present in spacecraft that are neither rotating nor accelerating. At present, there is no confirmed technique as such that can simulate gravity other than actual rotation or acceleration. There have been many claims over the years of such a device. [[Eugene Podkletnov]], a Russian engineer, has claimed since the early 1990s to have made such a device consisting of a spinning superconductor producing a powerful "[[Gravitomagnetism|gravitomagnetic]] field." In 2006, a research group funded by [[European Space Agency|ESA]] claimed to have created a similar device that demonstrated positive results for the production of gravitomagnetism, although it produced only 0.0001&nbsp;''g''.<ref>{{cite web|url=https://gsp.esa.int/article-view/-/wcl/Fd1ZihgaGrwB/10192/towards-a-new-test-of-general-relativity-|title=Toward a new test of general relativity?|publisher=Esa.int|access-date=2013-08-06|archive-url=https://web.archive.org/web/20171228000202/https://gsp.esa.int/article-view/-/wcl/Fd1ZihgaGrwB/10192/towards-a-new-test-of-general-relativity-|archive-date=December 28, 2017|url-status=dead}}</ref>
