The present invention, called the practical time machine, requires teams of super intelligent robots that work together in the virtual world and the real world to generate a perfect timeline of planet Earth. The timeline of Earth uses a myriad of computer technologies and Super AI to record and track all atoms, electrons, and E.M. radiation on Earth every fraction of a nanosecond for the past, present, and future. Next, atom manipulators are used to change objects in our current environment based on the timeline. Each atom manipulator is intelligent and manipulates the current environment, as well as, generating ghost machines to create intelligent pressure or controlled forcefields to manipulate objects in our current environment. It’s primary function is to manipulate atoms and its elemental parts to do the following: move atoms, position atoms to a fixed location, merge atoms to form complex molecules, and break molecules apart into individual atoms. This type of time travel is practical and solves existing paradox problems, such as the grandfather paradox. And believe it or not, particle physics is using these techniques right now (AI) to find molecule orientations and combinations (Example: finding vaccines for Covid-19). In order to bring a dead person back to life, the device has to break apart every atom in a human being (mostly water molecules), and put said atoms back together again in a different time state. Nature breaks apart water molecules (from heat) and conversely merges water molecules (through rain) all the time. The Practical time machine is simply breaking apart water molecules and merging water molecules together to form objects in an intelligent and controlled manner, using super artificial intelligence. Also, components of the practical time machine can be used to create any science fiction technology or superhero powers, such as: forcefields, tractor beams, ray guns, levitation, invisibility, anti-gravity machines, hoverboards, teleportation, telekinesis, UFO ships. It can even: control the weather, stop or prevent natural disasters, turn rock into gold, and so on. The atom manipulator imbues sentient robots with superpowers, and capable of replicating any superpowers found in Marvel comics, DC comics, or Image comics. Patent: US 12/471,382
