Reseña del libro "Harry's Time Tours (en Inglés)"
Just because it didn't happen here doesn't mean that it never happened. Causation is a collection of memoirs of Harry Black, the founder of Harry's Time Tours. This tells of the early years, when Harry was first transported to this world and met his beautiful sidekick and wife, Mary. And the final years, when Harry was moving the company off planet to avoid confiscatory taxes and regulations. Harry is different. The Many Worlds Interpretation is mostly correct, but there probably are just many worlds, instead of the infinity of worlds that Everett theorized, and it is possible to communicate from one world to another, and Harry is living proof of that, because he is from a different space-time. In the world that Harry is from time travel is not just possible, but it is a common way to have a vacation, and it is an excellent tool for researching history and anthropology. Harry was on a time trip when he ended up in this world, so his time machine came along with him. If you have a question about the past, then Harry can help you. Whether you want to witness the assassination of Julius Caesar, or you wonder about Catherine the Great and either cavalrymen or their steeds, Harry can get you to the time and place. Have you ever wanted to spend an evening with Cleopatra or watch the defeat of Troy? Harry can provide transport to any time and place in the history of humanity, and if you don't know exactly when, he can do the research to find the time and place that something happened. If your interest is criminal, then he might still be interested.Keep in mind that anything that you change in the past will create a new space-time, and it won't alter the history of this world. So kill Hitler in 1923, if you want, but it won't change what happens in this world, but be careful with the future. The Really Great Pandemic is up there, and it is incurable, and the mortality rate is high. On the other hand, the virus inserts a bit of DNA that keeps telomeres from deteriorating with all that implies.Harry isn't the only one with time travel. There are the ones who claim to be the Time Police, but there's more to them than just that.
