A Columbia University professor has introduced an unusual theory — that humans have yet to discover alien life because it could be woven into the fabric of the universe and even physics itself.

Astrophysicist Caleb Scharf presents this idea in a piece published on the website Nautilus.

According to him, some believe technology might progress so far that "...we wouldn't even realize we were staring at it....it would neatly explain why we have yet to see advanced intelligence in the cosmos around us, despite the sheer number of planets it could have arisen on..."

In this combo photo, the head of New Zealandâs Mount John Observatory said on Jan. 2, 1979, that the unidentified flying objects filmed by Australian TV men were almost certainly the Planet Venus. Photo at left is from the TV film made over the weekend off the coast of New Zealand. Photo at right is of the Planet Venus made in 1974 by the Mariner space probe. New Zealand astronomer David Mabin said Venus is currently at its brightest and can be seen for about 12 hours a day. Another expert said the radar echoes reported were probably âRadar Angelsâ which are common in the Southern Hemisphere at this time of year. (AP Photo)

Michael Savage, 15-year-old son of prominent San Bernardino physician and surgeon, was practicing picture-taking with his new camera, when he saw motion out of the corner of his eye Thursday, July 24, 1956, San Bernardino, CA. He quickly shot this picture, tried to shoot another and in his haste, over-cranked the camera, drawing a blank with his second shot. The object disappeared in 30 seconds, he said, not over the horizon but quickly out of sight in the sky. (AP Photo/Michael Savage)
Texas farmer Carrell Wayne Watts told a polygraph operator this Polaroid snap shows an alien spacecraft 80 to 100 feet long, Sunday, Feb. 25, 1968, Amarillo, Tx. The Houston Post will release results of 29-year-old Watts lie test late Sunday night. (AP Photo/Carrell Wayne Watts)

This photo is from the Air Force's "The Roswell Report," released Tuesday, June 24, 1997, which discusses the UFO incident in Roswell, N.M. in 1947. On balloon flights, test dummies were used and placed in insulation bags to protect temperature sensitive equipment. These bags may have been described by at least one witness as "body bags" used to recover alien victims from the crash of a flying saucer. The 231-page report, released on the eve of the 50th anniversary of the Roswell, N.M., UFO incident, is meant to close to book on longstanding rumors that the Air Force recovered a flying saucer and extraterrestrial bodies near Roswell.

He prepared his 4" X 5" Press Camera, set it at F8 and 1/100 shutter speed, and snapped one good black and white picture of the object. (AP Photo)
Described as a leisure home of the 1970s, this flying saucer-shaped house - called the 'Futuro' - is made up of 16 pre-moulded segments of fibreglass. Designed by Finnish architect Matti Suuronen, it is being made under license from Oy Polykem of Helsinki by a Lancashire firm (Waterside Plastics Ltd, of Todmorden) and is described as the leisure home of today and tomorrow.

Scharf also notes that, given the possibility that other building blocks of life exist outside of molecules, "a civilization could then transcribe itself and its entire physical realm into new forms. Indeed, perhaps our universe is one of the new forms into which some other civilization transcribed its world."

Scharf points out, "...only about 5 percent of the mass-energy of the universe consists of ordinary matter: the protons, neutrons, and electrons that we're composed of. A much larger 27 percent is thought to be unseen, still mysterious stuff."

He also questions if the universe's past unpredictable ways, such as a rapid expansion 5 billion years ago, could be the result of alien manipulations.

Overall, Scharf considers these possibilities to be fun and hopes a lab can one day detect life in dark matter.

The Haleakala silversword (Argyroxiphium sandwicense subsp. macrocephalum) is a rare plant found only the island of Maui on the dormant Haleakala volcano.Silverswords live between 3 and 90 years or more. They flower once, sending up a spectacular flowering stalk, and then die soon afterward, scattering drying seeds to the wind. Flowering events can differ dramatically from one flowering season to the next. The reasons for that are not understood.
