"Something very interesting happened at CERN recently – they had an accident. The accident created a “rainbow” universe. What does this mean, exactly? CERN actually created a universe for 2.6 seconds."
This is based on an April Fools joke posted on the NOVA Next blog, April 1, 2015.
"Jessica Czerniski", who is quoted in the article, is a made-up name, and all Google hits for that name lead to copies of this article. I found no other indication of anyone by that name having actually worked at CERN.
