According to our current understanding of physics, traveling faster than the speed of light is not possible for several reasons. One of the fundamental principles of modern physics is Einstein's theory of relativity, which states that as an object with mass approaches the speed of light, its mass increases, and the energy required to accelerate it further becomes infinite. This means that it would require an infinite amount of energy to accelerate an object with mass to the speed of light, let alone beyond it.
Additionally, as an object with mass accelerates, its length in the direction of motion contracts and time dilates. At the speed of light, time dilation becomes infinite, and length contraction reduces the length of the object to zero. These effects, known as time dilation and length contraction, make it impossible for an object with mass to reach or exceed the speed of light.
While faster-than-light travel is currently considered impossible, scientists are exploring concepts such as space-time warping and wormholes as theoretical possibilities for faster interstellar travel. However, these concepts are purely speculative and still far from being realized technologically, as they require understanding and control over exotic phenomena, such as negative energy densities and traversable wormholes, which are currently beyond our scientific capabilities.
For now, our best hope for exploring other planets and celestial bodies is through robotic missions, such as probes and rovers, which can be sent to space to gather information and transmit it back to us. These missions have provided us with valuable data about our solar system and beyond.
