In 1995, Bigelow founded the National Institute for Discovery Science to fund the research and study of various fringe sciences and paranormal topics, most notably ufology. The organization researched cattle mutilation and black triangle reports, ultimately attributing the latter to secretive advanced aircraft operated by the military. The institute was disbanded in 2004.

In 1996, Bigelow purchased Skinwalker Ranch, a 512-acre (205 ha) cattle ranch located in Utah that is the site of purported paranormal phenomena, such as inter-dimensional shape-shifters, for $200,000. In 2016, Bigelow sold the ranch to Brandon Fugal for $500,000.

In December 2017, Bigelow was reported by The New York Times to have urged Senator Harry Reid to initiate what became the Advanced Aerospace Threat Identification Program, a government study which operated from 2007 to 2012 tasked with the study of UFOs. According to the New York Times, Bigelow said he was “absolutely convinced” that extraterrestrial life exists and that extraterrestrials have visited Earth.
