Abstract: Since the special theory of relativity came out,probing time-space transformation which is different from classic theory of relativity has always been an interesting topic for the theory-circles.The theory of relativity has experienced strict practice and has had sound groundwork.In order to explore a new time-space transformation in the field of the theory of relativity,from the concept of negative energy,the paper summarizes the developing process of negative energy from a physically assistant computing device to a real existing physical concept.Through theoretical analysis,the author discovers that the idea of the mass of negative energy particles being negative breaks some physical fundamentals,such as the second Law of Newton.A conclusion is drawn that the mass of negative energy particles is positive,and its time-space is different from ordinary matter.It is found that energy emission will take place while the negative and the positive energy particles interact.
