Yes, it is possible to "travel" into the future without physically traveling through time in the traditional sense. This concept is based on the principle of time dilation, which is a consequence of Einstein's theory of relativity.
According to the theory of relativity, time can pass at different rates depending on the relative motion and gravitational fields experienced by observers. Specifically, when an object or person moves at speeds close to the speed of light or in the vicinity of a massive object, time for that object or person will pass slower compared to a stationary observer.
This phenomenon is known as time dilation. As a result, an object or person that experiences time dilation will effectively age more slowly than an observer who is not subject to such conditions. When they return from their journey, they will find that more time has passed for the stationary observer, effectively "traveling" into the future from the perspective of the stationary observer.
One practical example is the famous "twin paradox." Suppose one twin travels into space in a high-speed spacecraft while the other twin remains on Earth. The traveling twin, due to their high velocity, will experience time dilation and age more slowly compared to the twin on Earth. When the traveling twin returns to Earth, they will find that the Earth-bound twin has aged more, effectively "traveling" into the future relative to their twin.
It's important to note that this form of time travel into the future is limited to the effects of time dilation. It does not allow for traveling to specific points in time or for interacting with events in the past or future. Additionally, achieving speeds close to the speed of light or encountering strong gravitational fields is currently beyond our technological capabilities for human-scale objects.
