Topic-How important are the opinions of experts in the search for knowledge

Opinion- We don't need to believe anything just because we have heard it, and experts are specialized in their own fields so they can't give any judgments just because they are experts.

Support 1- For years, the whole world thought Pluto was a planet, until someone discovered it was a little too small to be classified as a planet. Everyone thought Pluto was a planet, so you can see even experts can make mistakes.

Support 2- Experts are not really experts after all. They can be called experts in science or whatever their field is, but why can't they know if there is life on other planets. this is a picture showing they cant always be right.
