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. The theory of relativity, which has been extensively tested and confirmed by experiments, establishes that as an object approaches the speed of light, its mass would become infinite and would require an infinite amount of energy to accelerate further.
However, if we were to consider a purely hypothetical scenario in which an object somehow traveled faster than light, it is difficult to predict the exact consequences it would have on time dilation and length contraction. Since our understanding of physics breaks down when dealing with superluminal (faster-than-light) velocities, the principles of relativity that govern time dilation and length contraction may not apply in the same way.
As of now, faster-than-light travel remains purely speculative and beyond the scope of known physics. Therefore, it is challenging to provide precise answers about the effects it would have on time dilation or length contraction.
