According to our current understanding of physics, specifically the theory of relativity, objects cannot travel faster than light in space under any circumstances. The speed of light, denoted by 'c,' is considered to be the ultimate speed limit of the universe.
In special relativity, which applies to objects moving in the absence of gravitational forces, it is postulated that the speed of light is the same for all observers, regardless of their relative motion. This principle, known as the constancy of the speed of light, forms the foundation of special relativity and has been extensively tested and confirmed by various experiments.
General relativity, on the other hand, describes the behavior of objects in the presence of gravitational fields. While gravity can cause significant effects on the motion of objects, it does not enable them to exceed the speed of light. In general relativity, the geometry of spacetime is influenced by mass and energy, and objects follow the curves of this geometry. However, even under the influence of strong gravitational forces, the speed of light remains the maximum attainable speed.
It's important to note that there are theoretical concepts such as wormholes and warp drives that have been proposed in science fiction and some speculative physics theories. These concepts involve exotic phenomena that could potentially allow for faster-than-light travel. However, at present, there is no experimental evidence or widely accepted scientific theory supporting the existence or practical realization of such phenomena.
Thus, based on our current understanding of physics, objects cannot travel faster than light in space, whether there is a massive gravitational force or not. The speed of light represents a fundamental limit on the motion of objects in the universe.
