Abstract

Whether time travel can be achieved in reality is often a matter of debate, and although many scientists have proposed a number of theoretical ways in which it might be possible, their feasibility remains to be studied. This paper firstly contrasts the absolute spacetime view and relative spacetime view to reflect the understanding of time and other physical quantities in relativity. Subsequently, this paper mainly analyzes seven existing methods of time travel, and introduces them respectively from theoretical principles, related theorems, current development status and development limitations. On this basis, the current situation and prospects of the overall development of time travel are outlined. Besides, the main research method of this paper is to collect various theses related to time travel methods and research data published by some space agencies with integration and analysis as well. This information is sometimes an in-depth study of part of each method, and sometimes a negation of one. But they all help paper to have a more comprehensive understanding, and lead to a conclusion that time travel requires not only the correct theories but also available technology and energy to support the journey to operate and keep astronauts safe.
