According to the theory of relativity, as formulated by Albert Einstein, an object with mass cannot travel at or exceed the speed of light. As an object with mass approaches the speed of light, its energy and momentum increase, making it more and more difficult to accelerate further. In fact, it would require an infinite amount of energy to accelerate a massive object to the speed of light.
Therefore, it is not possible for an object with mass, such as yourself, to travel at the speed of light and shine a torch ahead. If you were somehow traveling at a speed very close to the speed of light, the speed of light itself would still appear to travel at the same speed relative to you. This is due to the constant speed of light in a vacuum as observed by all observers, regardless of their relative motion.
From your perspective, if you were traveling very close to the speed of light and shined a torch ahead, the light emitted from the torch would still propagate at the speed of light relative to you. However, an observer outside your reference frame, at rest relative to you, would still measure the speed of light emitted from the torch to be the same as if you were at rest, which is the speed of light in a vacuum. This is known as the principle of the constancy of the speed of light.
