“The very concept of time travel makes no sense, since time doesn’t’ flow. The fact that we think time passes is just an accident of our nervous systems – of the way things look to us. In reality, time doesn’t pass; we pass. Time itself is invariant. It just is. Therefore, past and future aren’t separate locations, the way New York and Paris are separate locations. And since the past isn’t a location, you can’t travel to it.”
They were silent. They just stared at him.
“It is important to be clear about this,” Gordon. “The ITC technology has nothing to do with the time travel, at least not directly. What we have developed is a form of space travel. To be precise, we use quantum technology to manipulate an orthogonal multiverse coordinate change.”
They looked at him blankly.
“It means,” Gordon said, “that we travel to another place in the multiverse.”
“And what’s the multiverse?” Kate said.
“The multiverse is the world defined by quantum mechanics. It means that – ”
“Quantum mechanics?” Chris said. “What’s quantum mechanics?”
Gordon paused. “That’s fairly difficult. But since you’re historians,” he said, “let me try to explain it historically.”
