According to our current understanding of physics, it is not possible for an object to exceed the speed of light in a vacuum. The theory of special relativity, proposed by Albert Einstein, states that the speed of light is an absolute speed limit in the universe. As an object with mass approaches the speed of light, its relativistic mass increases, requiring an infinite amount of energy to reach or exceed the speed of light.
Regarding folding space-time, this concept is often associated with the idea of wormholes or Einstein-Rosen bridges. A wormhole is a hypothetical shortcut through space-time that could potentially connect distant points in the universe. However, there are significant theoretical and practical challenges associated with the existence and stability of wormholes.
The problem with using wormholes for faster-than-light travel is that they would need to be carefully controlled and stabilized to prevent their collapse or the occurrence of negative energy densities, which are currently not understood or observed. Additionally, even if stable wormholes could exist, we would still need a means of entering and exiting them, which introduces further complications.
It's important to note that our current knowledge is limited, and future scientific discoveries may change our understanding of these concepts. However, as of now, faster-than-light travel remains purely speculative and unsupported by scientific evidence.
