According to our current understanding of physics based on Einstein's theory of relativity, it is not possible for an object with mass to travel through space faster than the speed of light. The theory of relativity sets a cosmic speed limit, where the speed of light in a vacuum, denoted by 'c,' is considered the maximum attainable speed.
As an object with mass approaches the speed of light, its relativistic mass increases, requiring an infinite amount of energy to accelerate it to the speed of light itself. This concept is known as mass-energy equivalence, described by Einstein's famous equation, E=mc². As the object's speed gets closer to the speed of light, its energy requirements become infinitely large, making it impossible to reach or exceed the speed of light.
However, it's important to note that the theory of relativity does allow for the theoretical possibility of spacetime itself expanding faster than the speed of light. This expansion is described in the context of the expanding universe and the concept of cosmic inflation. It is the fabric of spacetime itself that expands, rather than objects moving through space faster than light.
It's worth mentioning that scientific understanding is continually evolving, and our current knowledge may be expanded or revised in the future. However, any proposed method of faster-than-light travel would need to provide substantial evidence and adhere to the existing principles of physics to be considered scientifically valid.
