Time travel
"I've got to finish it" Dewit explained to Hewit. "It's taken me 90 years working nearly 14 hrs a day to get here. I must finish it"
Hewit looked at the semi-complete machine. "If you could make it work where would you go?"
"I'd go back to the day I was about to start working on this time machine", Dewit replied, his voice trembling
"And what would you do once you got there?" Hewit asked curiously
Dewit smiled slightly at the possibility "I'd talk myself out of trying to invent this and convince myself to live my life instead"
Hewit nodded but he felt sad for the older Ewit. Hewit knew that what Dewit wanted was impossible. If Dewit of the future had gone into the past and convinced himself not to work on the time machine then Hewit and Dewit wouldn't have been there talking about it.
There was no other way the universe could have been than exactly the way it was right now. But he knew he wasn't the one who was going to give the news to Dewit.
