According to our current understanding of physics, it is not possible for an object with mass to travel faster than the speed of light in a vacuum. As an object with mass accelerates, it requires more and more energy to increase its speed, and as it approaches the speed of light, its relativistic mass increases towards infinity. In other words, it would take an infinite amount of energy to accelerate an object with mass to the speed of light, let alone beyond it.
Moreover, as an object with mass approaches the speed of light, time dilation occurs, meaning that time slows down for the moving object relative to a stationary observer. From the perspective of the moving object, time would appear to pass more slowly, but for an outside observer, time would still progress at its normal rate. As the object approaches the speed of light, time dilation becomes more significant, and it would effectively take an infinite amount of time for the object to reach or exceed the speed of light.
So, based on our current understanding, it is not possible to travel faster than the speed of light, and therefore concepts such as arriving before you left or traveling backward in time do not apply. The theory of relativity establishes the speed of light as an absolute cosmic speed limit, and any attempt to surpass it would require violating the fundamental principles of physics as we currently understand them.
