According to our current understanding of physics, it is not possible for an object with mass to travel at or exceed the speed of light in a vacuum without violating the laws of physics as we know them. This is based on Einstein's theory of relativity, which has been extensively tested and confirmed by numerous experiments.

As an object with mass accelerates towards the speed of light, its relativistic mass increases, requiring an infinite amount of energy to reach the speed of light. This energy requirement is not practically achievable within the known laws of physics.

Furthermore, as an object with mass approaches the speed of light, time dilation and length contraction occur. Time dilation means that time appears to slow down for the moving object relative to a stationary observer, while length contraction means that the length of the object appears shorter in the direction of motion. These effects prevent an object with mass from reaching or exceeding the speed of light.

It's worth noting that particles without rest mass, such as photons (particles of light), travel at the speed of light in a vacuum. However, they are inherently massless, and their behavior is governed by the laws of quantum mechanics.

While there have been speculative theories and concepts proposed, such as wormholes or warp drives, which suggest methods of circumventing the speed-of-light limit, they are purely theoretical and not currently supported by empirical evidence or widely accepted scientific understanding. These concepts involve hypothetical and currently unknown physics, and their realization, if possible, would require advancements beyond our current knowledge and technology.
