Is time traveling really possible?

Many people have been asking the same after video footage appears to show a woman talking on a cellphone - in 1928. The footage is from the premiere of Charlie Chaplin's silent film The Circus and was spotted by Belfast filmmaker George Clarke back in October of 2010. In the black-and-white footage, a group of young women walk by the camera and one of them, a brunette in the middle, smiles while talking with her hand to her ear, seemingly holding something to it.

The mystery may now be solved since recently a YouTube commenter under the handle Planetcheck claimed to know the woman in the footage.

The YouTube clip with Planetcheck's original comments has since been removed but the Daily Mail and Yahoo! News blog The Sideshow copied some of Planetcheck's claims before the video was taken down. In the posts Planetcheck admitted to being the grandchild of the cell phone woman, whose name is Gertrude Jones, and added that the actress was not a time traveler.

"She was 17 years old. I asked her about this video and she remembers it quite clearly," Planetcheck wrote. "She says Dupont [the company that reportedly owns the factory in the video] had a telephone communications section in the factory. They were experimenting with wireless telephones. Gertrude and five other women were given these wireless phones to test out for a week. Gertrude is talking to one of the scientists holding another wireless phone who is off to her right as she walks by."

However, even the idea of "wireless telephones" in the 1920s left many skeptical if Planetcheck's statements were true. YouTube commentators asked why such a device was then not revealed or talked about for at least several decades. Planetcheck responded by blaming factory owners.

"Maybe they decided it was too far advanced for people and they abandoned the idea," Planetcheck wrote. "Ideas are hatched, prototypes are made and sometimes like this phone they are forgotten until somebody discovers some long lost film of the world first wireless phone and marvels at it."

Planetcheck also gave a description of the phone - about 5 inches long and 3 inches wide - and claimed to still have it in a glass box.
