And while most scientists say time travel isn't possible, a Washington attorney claims he's done it dozens of times as part of a secret Cold War project.
"I have physically traveled in time," says Andrew Basiago, an attorney in Vancouver, Wash. "We have - we did over 40 years ago."
Now Basiago is on a mission - to reveal what he calls a 40-year government cover-up - of Project Pegasus - where he says he was teleported back and sideways in time, dozens of times.
"I have the whole story, I have hundreds of facts," he says. "I can tell you what personnel were at what locations where and which travel device was being used."
And his time travel wasn't recent - it's when he was a kid.
"I entered the program officially in the fall of 1969 as a third grader, age 7," says Basiago.
He says he was one of 140 kids, 60 adults - chrononauts, including his dad, who he says joined him on his first jump.
"My dad held my hand, we jumped through the field of energy, and we seem to be moving very rapidly but there was also a paradox and we seemed to be going no where at all," he says.
The TV show "Fringe" aired a similar scene two years ago. A coincidence?
Paradoxes, unscientific claims, unbelievable stories and encounters on Earth and Mars - including meeting Barack Obama when the president was a kid.
Basiago also says he time-traveled six times to the Ford Theatre on the day President Lincoln was shot - but he didn't see it happen. He also saw President Lincoln on another famous occasion, he says.
"In fact, during one probe, the one to Gettysburg, the Gettysburg Address, I was dressed as Union bugle boy," he says.
That's right - he was at the Gettysburg Address. He says a famous photo taken that day proves it. The picture shows a bugle boy who he says is him. It's the only visual evidence he provides for any of his travels - nothing else.
"I was physically at Gettysburg," says Basiago.
He says his time travel experiences show that teleportation as protrayed on the "Star Trek" series is all wrong.
"No, in fact if you had just arrived via quantum teleportation, the Star Trek method of teleportation, you would have collapsed as a dead person," he says.
Basiago weaves his tale with such conviction, he's either a psychopathic liar, a lunatic - or the fastest-thinking science fiction writer on Earth.
"A tunnel was opening up in time-space just like a soap bubble being blown by a child," he says. "And when that bubble closed, we were repositioned elsewhere in time-space on the face of the Earth."
Some would say Basiago is still living in a bubble, but he's put his professional reputation at risk claiming time travel isn't science fiction - because he did it.
It was hard for KOMO News to confirm any of Basiago's claims. Still, he says many out there say they believe Project Pegasus was real.
