The ancient Greeks thought the Sun revolved around the earth. We didn't figure out the truth until 500 years ago, and it hasn't been that long since science though the sun's heat came from burning coal.

Even early in the 20th century science thought the universe was only as big as our own Milky Way until Hubble proved that those smudges of light were actually other galaxies BILLIONS of light-years away rather than just clouds of gas in our own galaxy.

Sometimes we don't understand how things work because we don't have enough information, and sometimes we just misinterpret what we observe.
