The government funded research on wormholes, dark energy, invisibility cloaking and the manipulation of extra dimensions, Motherboard is reporting.

The website said the funds came through the Department of Defenses’ Advanced Aerospace Threat Identification program.

The Defense Intelligence Agency released a list of the funded research titles on Wednesday. The release came after Steven Aftergood, director of the Federation of American Scientists' Project on Government Secrecy filed a request under the Freedom of Information Act.

The titles included:

“Traversable Wormholes, Stargates and Negative Energy,” led by Eric David of EarthTech International.

“Invisibility Cloaking” headed by Ulf Leonhardt, a professor of the Weizmann Institute of Science in Israel.

“Warp Drive, Dark Energy, and the Manipulation of Extra Dimension” led by theoretical physicist Richard Obousy.

“The list of research papers tells us something more than previous reporting did about this odd program,” Aftergood told Motherboard. Now we have a better idea of exactly what the Defense Intelligence Agency was up to, and what it produced.”

He added: “I think anyone who looks at these titles will scratch their heads and wonder what on earth the Defense Intelligence Agency was thinking. These are the kinds of topics you pursue when you have more money than you know what to do with.”

The program had been set up to investigate UFOs. The Pentagon spent $22 million on the program between 2007 and 2012.
