What did Parmenides believe about movement in the universe?

Parmenides, a pre-Socratic philosopher, posited that change and movement are ultimately illusions. He argued that reality is unchanging and that sensory perception, which suggests that movement and change exist, is deceptive. According to his philosophy, true knowledge can only be obtained through rational thought and reasoning, wherein one understands that the universe is defined by a singular, unchanging existence. This perspective fundamentally challenges the notion of change as a reality, asserting that what we perceive with our senses, including movement, does not accurately reflect the true nature of being. Thus, Parmenides concludes that movement is not a genuine aspect of the universe, but rather a false impression formed by sensory experiences.
