According to the theory of relativity, specifically the theory of special relativity, it is not possible for an object with mass to travel at the speed of light. As an object with mass accelerates towards the speed of light, its mass would effectively become infinite, requiring an infinite amount of energy to continue accelerating.

However, let's assume for the sake of the thought experiment that you are traveling at a speed very close to the speed of light. In this scenario, according to the principles of special relativity, the speed of light in a vacuum would still be the same for you as it would be for an observer at rest relative to you. This means that if you shine a torch ahead of you, the light emitted from the torch would still move away from you at the speed of light.

From your perspective, the light emitted by the torch would appear to move away from you at the speed of light, just as it would for an observer at rest relative to you. However, it is important to note that this scenario is purely hypothetical, as objects with mass cannot reach or exceed the speed of light according to our current understanding of physics.
