According to our current understanding of physics, both the speed of light and infinite velocity are considered to be impossible to reach. Let me explain why:
Speed of Light: The speed of light in a vacuum, denoted by "c," is approximately 299,792,458 meters per second. According to Einstein's theory of relativity, as an object with mass accelerates towards the speed of light, its energy increases and its mass appears to increase as well. As an object approaches the speed of light, the energy required to accelerate it further becomes infinite. This means that any object with mass would require an infinite amount of energy to reach or surpass the speed of light. Therefore, from our current understanding, it is impossible for an object with mass to travel at or exceed the speed of light.
Infinite Velocity: Infinite velocity refers to a velocity that is infinitely greater than any finite number. It implies moving an object from one point to another in an infinitely small amount of time. Infinite velocity contradicts our current understanding of physics because it violates the principles of causality and time. Causality states that an effect cannot occur before its cause. If an object were to move with infinite velocity, it would arrive at its destination instantaneously, even if the starting point and destination were arbitrarily far apart. This would lead to a breakdown of cause and effect relationships, which are fundamental to our understanding of the universe. Therefore, infinite velocity is considered impossible based on our current knowledge.
It's worth noting that our understanding of physics is based on current theories and may evolve with new discoveries and breakthroughs. However, the speed of light is regarded as the ultimate cosmic speed limit, and infinite velocity remains a concept that is incompatible with our current understanding of the universe.
