Conspiracy of the Morlocks

When Traveler returned from the year 80,000 in the land of Morlocks and Eloi, he was unsettled. His friends, George and Elizabeth worried about him. In the present time, George met an attractive woman from the future that died from the Morlocks in the future. George suggested that they could return to the future and save the woman. They stopped in the year 2000 to get more radium to enable the threesome to go to the future, were reading books, and saw a book about conspiracies with George Orwell's 1984 book about a New World Order pretty much enslaving humanity. The time machine was modified so it could travel to other locations besides going back in time. After a few stops in the twenty-first century to get needed supplies, they went to the year 80,000. They met a Morlock different from the ones previously encountered and that Morlock led them to another group of people who referred to themselves as "Growers". At that community was a device called "Guide" that was a hologram. The guide had knowledge gained from thousands of years and was able to display images. Guide helped show the threesome past events that led to pretty much destroyed humanity. They continued backward in time and one thing they encountered was the world greatly covered by water but not totally so. They also visited the Garden of Eden. With such power, the idea came to ponder about going back to change was to become the future. Good in theory. Could it be done?
