The concept of time travel, particularly traveling backward in time, is largely theoretical and speculative at this point. The question of whether antimatter could move forward in time is speculative as well.
In the realm of physics, the behavior of antimatter is typically described in terms of its interactions with matter and the fundamental forces of nature. Antimatter particles, such as antielectrons (positrons) or antiprotons, have the same mass as their corresponding matter particles but possess opposite charges. When matter and antimatter particles come into contact, they annihilate each other, releasing energy.
Regarding the behavior of antimatter in relation to time, the laws of physics, as currently understood, do not suggest any inherent difference between the way matter and antimatter interact with time. Both matter and antimatter are subject to the flow of time, and their behavior is governed by the same fundamental physical laws.
However, it is important to note that the specific properties and behavior of antimatter are still being studied and researched, particularly in the context of particle physics and cosmology. While antimatter has been produced and studied in controlled experiments, there is still much to learn about its fundamental nature and its potential implications for phenomena such as time travel.
