According to our current understanding of physics, time travel to the future is theoretically possible, but it would require travel at extremely high speeds or within strong gravitational fields, as predicted by the theory of special and general relativity. However, it's important to note that such forms of time travel to the future would not allow you to interact with or observe specific events in your own future.
If you were to travel to the future using these methods, time would appear to pass more slowly for you compared to observers who remain in a relatively stationary or weaker gravitational field. As a result, you could potentially experience the passage of, for example, a few hours while a significant amount of time passes on Earth, which might be years or even centuries in the future.
However, it's crucial to understand that this form of time travel to the future would be more akin to "time skipping" rather than actively witnessing or influencing specific events. You would effectively be leaping forward in time and experiencing a future that has already unfolded without the ability to alter or affect it.
As for the impact on your own life, if you were to travel to the future and observe the events that transpire, it would likely provide you with knowledge about what lies ahead. This knowledge could potentially influence your decisions and actions when you return to your original time, altering the course of events and potentially changing the future you witnessed. This concept is known as the "grandfather paradox," where an action in the past (or knowledge of the future) leads to a contradiction or alteration of events.
It's worth noting that time travel to the future and its potential consequences are still largely theoretical and speculative. The complexities and paradoxes associated with time travel are subject to ongoing scientific and philosophical discussions. At present, no practical means of time travel to the future have been achieved, and the implications for our lives remain in the realm of speculation and creative imagination.
