According to our current understanding of physics, faster-than-light (FTL) travel is not possible. The theory of relativity, proposed by Albert Einstein, sets an upper limit on the speed of light as a fundamental constant of the universe. It states that as an object with mass approaches the speed of light, its energy requirements become infinite. This is commonly referred to as the "mass-energy equivalence" principle.
Furthermore, as an object with mass accelerates, its relativistic mass increases, making it more and more difficult to reach the speed of light. At the speed of light, an object with mass would require an infinite amount of energy to accelerate further, which is not feasible.
There are also other challenges associated with FTL travel, such as causality violations and the creation of time travel paradoxes. The notion of causality, cause and effect, is fundamental to our understanding of the universe, and FTL travel would potentially allow for situations where events occur before their causes, leading to logical inconsistencies.
While there is ongoing scientific research and exploration of theoretical concepts such as wormholes and warp drives, these ideas currently remain purely speculative and highly hypothetical. They involve manipulating exotic concepts like negative energy or bending spacetime in ways that are not yet fully understood or confirmed to be possible.
Given our current understanding of physics, it is difficult to predict when or if FTL travel will ever become available to humans. It would require significant advancements in our understanding of fundamental physics and the development of technologies and materials that are currently beyond our capabilities. As of now, there is no scientific consensus on whether it will ever be possible to achieve FTL travel.
