Let me debunk your idea of space coffin. First of all, we don't have the technology to achieve absolute zero, and there is no significant material that can be used to achieved that coldness. You don know the concepts of thermodynamics if I presume cause you are talking about freezing the person.

then can you care to explain me about the Non-freezing solution. But if your reply is just based on movies, then nevermind.

Though I want you to reference something like time travel, for I am fan of sci-fi movies that involves time travels
