According to our current understanding of physics, travel at the speed of light is not theoretically possible for material objects with mass. The theory of special relativity, proposed by Albert Einstein, states that as an object with mass accelerates and approaches the speed of light, its energy requirement to continue accelerating becomes infinitely large. This means that it would require an infinite amount of energy to reach or exceed the speed of light, which is not feasible with our current technology or understanding of physics.
It is important to note that scientific theories are not "universal truths" in the sense of being absolute and unchanging. Scientific theories are models or explanations of natural phenomena that are supported by a vast body of evidence and have undergone rigorous testing and scrutiny. They are our best current explanations for how the natural world works, but they are subject to revision and refinement as new evidence and observations emerge.
As for electromagnetic propulsion, it refers to the concept of using electromagnetic forces to propel an object. One example is ion propulsion, where ions are accelerated using electric fields to generate thrust. Electromagnetic propulsion is an active area of research and has been employed in certain applications, such as ion thrusters used in space probes. However, it is important to distinguish between different types of electromagnetic propulsion, as the term can encompass a range of technologies and concepts.
Regarding the idea that our physics are flawed, it is essential to recognize that scientific understanding is an ongoing process of exploration and refinement. Our current theories and models, such as those encompassed by the fields of classical physics and quantum mechanics, have proven to be highly successful in explaining and predicting a vast array of phenomena. However, they may not provide a complete understanding of the universe, particularly in extreme or unexplored domains.
Scientific progress often involves discovering limitations or inconsistencies in existing theories, which can lead to the development of new theories that better explain observations or offer more accurate predictions. Physics is a dynamic field, constantly evolving as new experiments, observations, and theoretical advancements are made. So, while our current understanding of physics has been incredibly successful, it is always subject to further refinement and expansion as we continue to explore the mysteries of the universe.
