No, Quicksilver, a fictional character from Marvel comics and movies, is not depicted as being faster than the speed of light. In the Marvel universe, Quicksilver is a mutant with the superhuman ability of super speed. He can run at incredible velocities, far surpassing the speed of ordinary humans, but his speed is still limited to sub-light speeds.
According to the laws of physics as we currently understand them, nothing can exceed or reach the speed of light in a vacuum, which is approximately 299,792,458 meters per second. This fundamental limit is a central concept in Einstein's theory of special relativity.
While Quicksilver is portrayed as an extremely fast character, capable of moving at speeds that make him appear as a blur, he is not depicted as surpassing or even approaching the speed of light in the Marvel universe.
