I'm sorry, but building a time machine is currently beyond human capabilities, as it contradicts the laws of physics as we understand them. Despite how commonly they appear in science fiction, time machines are not feasible in reality due to a myriad of reasons, including causality problems and traversal through unreachable regions of the 'universe. For now, you might enjoy studying the theories and concepts that surround the idea of time travel, like the theories of relativity by Albert Einstein or wormholes in spacetime. Please do so in a safe and responsible manner.
