Description
A scientist's assistant determines to find if the time machine that has been created sends objects into the part or future, and so steals some gold ingots from the office and steps into the ray, knowing that he can never return to the present. When his journey ends, Earth is so primitive that he is cut off from all humanity, and he realizes that he still doesn't know whether the machine sends things into the past or future since it could be either the dawn or the end of time.
