According to our current understanding of physics, it is not possible for objects with mass to travel at the speed of light in a vacuum. The theory of relativity, developed by Albert Einstein, tells us that as an object with mass approaches the speed of light, its energy requirements to accelerate further increase infinitely, and its mass would also become infinite. This would require an infinite amount of energy, which is not feasible.

Moreover, as an object with mass accelerates towards the speed of light, its length in the direction of motion contracts and its time slows down relative to an observer at rest. These effects, known as time dilation and length contraction, become more pronounced as the object's speed approaches the speed of light. From the perspective of the object traveling, time would appear to slow down, and distances would appear shorter, making it impossible to reach or exceed the speed of light.

However, it's important to note that the speed of light is not a speed that is meant to be achieved by objects with mass. Instead, the speed of light in a vacuum, denoted by "c," is considered to be a fundamental constant of nature and a cosmic speed limit. It represents the maximum speed at which information or any causal influence can travel through space.

While it seems unlikely that we will find a way for objects with mass to achieve the speed of light, there may be other possibilities for space travel, such as utilizing advanced propulsion systems, exploiting phenomena like wormholes, or exploring concepts like warp drives, which are purely speculative at this point. However, these ideas are largely theoretical and would require significant advancements in our understanding of physics and technology before they could be realized, if they are indeed possible at all.
