Skepticism
UFOs
Regarding the
Roswell UFO incident
The Roswell Incident started in 1947 with the recovery of debris near Roswell, New Mexico. It later became the basis for conspiracy theories alleging that the United States military recovered a crashed extraterrestrial spacecraft. The debri ...
, Thomas has joked that "My theory...is that the Roswell ship did not actually crash, that it only landed and took off again and continued to land at all these other sites." He maintains that the incident involved a crashed
Project Mogul balloon and was not in any way related to extraterrestrial activity. Thomas also frequently discusses the
Aztec, New Mexico, UFO incident hoax, and his explanation of the scam at the Aztec UFO Symposium ended his regular speaking appearance there. The Symposium's last meeting was in 2011. In 2009, Thomas presented at UFOcon in Tucson, Arizona, where he covered both incidents.
Bible code
Thomas has applied his knowledge of mathematics and computer engineering to dispute the credibility of the

. They discussed the geographic patterns and implications of global warming as well as refuting the idea that human interference has a negligible effect on the crisis.
That same year, Thomas joined more than 60 fellow skeptics clarifying the media's use of "skeptic" and "denier" when discussing those who undermine and reject climate science. The letter explains that "Proper skepticism promotes scientific inquiry, critical investigation, and the use of reason in examining controversial and extraordinary claims. It is foundational to the scientific method. Denial, on the other hand, is the ''a priori'' rejection of ideas without objective consideration."
The 9/11 Truth movement

Thomas has engaged in several public debates with advocates of the
9/11 Truth movement. After offering a live refutation to architect Richard Gage's 2009 New Mexico Tech alumni weekend presentation on the collapse of the

Creationist legislation and intelligent design
In February of 2011, the Education Committee of the New Mexico House of Representatives voted 5-4 to table House Bill 302, which sought to prevent public school teachers from being disciplined or removed from their positions for teaching "relevant scientific information regarding either the scientific strengths or scientific weaknesses pertaining to 'controversial' scientific topics". Thomas testified his concern that the bill "is really just a ploy to get

New Mexico's existing standards already protect students from religious indoctrination or harassment by their teachers.
