Based on our current scientific understanding, it is not possible for a vehicle or any object with mass to achieve or exceed the speed of light in a vacuum. As an object with mass accelerates towards the speed of light, its energy and momentum would approach infinity, requiring an infinite amount of energy to continue accelerating. This violates the principles of our current physics.
Additionally, as an object approaches the speed of light, time dilation occurs according to the theory of relativity. Time would slow down for the object relative to a stationary observer, and at the speed of light, time would effectively stop. This means that, from the perspective of the object, the entire universe would appear to contract to a single point.
It's worth noting that even if it were hypothetically possible to reach the speed of light, the challenges and consequences associated with achieving such speeds, including the immense energy requirements and time dilation effects, make it highly improbable in our current understanding of physics.
However, it's important to keep in mind that scientific knowledge is not static, and future discoveries or advancements may lead to new understandings and possibilities. Speculative theories, such as those involving wormholes or other concepts, have been proposed in science fiction, but their feasibility and scientific basis remain speculative at this point.
