Is time travel possible? Local engineer says 'yes'

ALAN FROMAN, ThisWeek Community News

Grandview Heights High School physics students saw a demonstration last week of a device its inventor believes could be the first step toward creating a time machine.Marshall Barnes, a research and development engineer who splits his time between Columbus and Yellow Springs, completed work in August on the device he calls a Verdrehung Fan.His appearance Friday, Nov. 2, at the high school was the first hands-on demonstration of his invention.Grandview High School is special to him, Barnes said, because he developed much of the technology he uses in his device at a lab he operated in the early 2000s on Dublin Road. He has made previous visits to the high school's science classes.

"If you wanted to go back in time and stop the Kennedy assassination, it wouldn't work because you would be in a parallel universe," he said. "The Department of Defense might worry about someone going back to help the Nazis win World War II, but it couldn't happen. "Historians could go back to study a particular time in history, Barnes said. But it would be impractical to go too far back, say, to ancient Egypt, he said, because no one would speak English and a modern human being would look conspicuously different from people from that time. Time-travel vacations could be a possible use of a time machine, Barnes said. He scoffs at noted theoretical physicist Stephen Hawking, who has dismissed the concept of time travel by asking where all the time-travel tourists are in the present day.

"They wouldn't want to make themselves known," Barnes said, comparing a time-travel tourist to a scientist studying animals in the wild.

"They stay hidden away so they can observe the animals without being detected."
