Even if it were possible, time travel to the future would only allow us to observe the future, not change it.

And it’s just possible that we could fast-forward that process through the phenomenon of time dilation. According to Einstein’s theory of special relativity, time passes at different rates depending on relative motion. A spacefarer moving at close to the …Time travel is possible based on the laws of physics, according to researchers. But time-travelers wouldn't be able to alter the past in a measurable way, they say.
