" Science progresses best when observations force us to alter our preconceptions. "
- Vera Rubin

Observations often serve as the cornerstone upon which scientific advancements are built. When we encounter facts or evidence that do not align with our existing beliefs, it prompts us to reevaluate and modify those preconceptions. This process is crucial for the advancement of science because it encourages a constant questioning of what we think we know.

The deeper meaning behind this statement lies in the importance of being open-minded and adaptable in the face of new evidence. It challenges us to move beyond stubborn adherence to old theories and embrace change when necessary. In scientific research, acknowledging that our current understanding may be incomplete or incorrect is a sign of intellectual maturity. By allowing observations to challenge and refine our preconceptions, we pave the way for groundbreaking discoveries and progress in various fields of study.

Vera Rubin was an American astronomer renowned for her work on galaxy rotation rates, which provided strong evidence for the existence of dark matter. Her meticulous observational studies often led her to question established theories, embodying the spirit of the quote she is associated with. Through her dedication to empirical research and willingness to challenge prevailing scientific beliefs, she significantly contributed to our understanding of the universe's structure and composition.
