According to the theory of special relativity, as an object approaches the speed of light, several significant effects occur, including time dilation. Time dilation means that the perception of time for a moving object will be different from that of a stationary observer.
From the perspective of the moving object, time appears to pass slower compared to a stationary observer. This effect becomes more pronounced as the object's velocity approaches the speed of light. However, it's important to note that this time dilation effect does not allow someone to "travel faster than time itself" or stop their own aging completely.
From the perspective of the moving person, they would experience time passing normally. It is only in comparison to a stationary observer that the time dilation effect becomes apparent. So, for the person traveling at near-light speeds, their own aging process would continue as usual. They would not perceive any significant changes in their subjective experience of time.
However, when the traveler returns to the reference frame of the stationary observer after an extended journey at relativistic speeds, they would find that less time has passed for them compared to the time that has passed for the stationary observer. This is often referred to as the "twin paradox," where one twin who goes on a high-speed journey will be younger than their sibling who stayed behind.
In summary, while time dilation occurs for objects traveling at high speeds, it does not enable someone to stop aging or experience time in a fundamentally different way. Time dilation is a relative effect that depends on the relative motion between observers, and it becomes apparent when comparing the experiences of differently moving objects.
