In every century people have thought they understood the Universe at last, and in every century they were proved to be wrong. It follows according to some that the one thing we can say about our modern "knowledge" is that it is wrong. My answer is when people thought the Earth was flat, they were wrong. When people thought the Earth was spherical they were wrong.
