While it is true that there have been instances in history where people made incorrect predictions about the limits of human achievement, it is important to distinguish between different types of technological advancements.
The idea of human flight was once considered impossible by many, but it was eventually achieved with the invention of airplanes. However, flight does not violate fundamental physical laws. It is based on principles of aerodynamics and the understanding of lift, thrust, and drag. The eventual realization of flight was made possible through the advancement of scientific knowledge and engineering principles.
On the other hand, faster-than-light travel, as currently understood, conflicts with our current understanding of physics. According to Einstein's theory of relativity, as an object with mass approaches the speed of light, its energy requirements and mass increase exponentially, making it increasingly difficult to accelerate it further. Additionally, the theory states that as an object with mass accelerates, its relativistic mass approaches infinity at the speed of light, requiring infinite energy to reach or surpass that speed.
While it is not possible to definitively claim that faster-than-light travel will never be achieved, our current understanding of physics suggests significant barriers and challenges. It is not merely a matter of technological development or engineering prowess; it would require a fundamental breakthrough in our understanding of the universe and the laws of physics.
That being said, scientific knowledge and understanding are not static, and our understanding of the universe continues to evolve. It is possible that future discoveries could lead to a revised understanding of physics and the development of new theories that allow for faster-than-light travel. However, as of now, it remains firmly in the realm of speculation and science fiction.
