According to our current understanding of physics, it is not possible for any object with mass to travel faster than the speed of light in a vacuum. The theory of relativity, specifically Einstein's special theory of relativity, establishes that the speed of light in a vacuum is the ultimate speed limit in the universe. As an object with mass approaches the speed of light, its energy requirements would become infinite.
However, if we consider a hypothetical scenario where an object surpasses the speed of light, it would lead to consequences that are not fully understood or supported by scientific evidence. Since this scenario falls outside the realm of established physics, it is difficult to predict what specific effects or phenomena would occur.
The notion of a "blackout" or a "rainbow wave" resulting from breaking the speed of light barrier is purely speculative and not based on any scientific principles. It is important to note that the behavior of light and the laws of physics are intricately connected, and any violation of the fundamental principles would require a radical reevaluation of our current understanding.
In summary, according to our current understanding of physics, exceeding the speed of light is not possible for objects with mass, and the specific consequences or phenomena resulting from such a scenario are purely speculative and not grounded in scientific evidence.
