"Our knowledge can only be finite, while our ignorance must necessarily be infinite"

This quote by Karl Popper speaks to the idea that our understanding is limited, while our lack of knowledge is vast. He is suggesting that, no matter just how much we learn, there will constantly be more that we don't understand. This is since deep space is so huge and complex that it is difficult for us to ever totally understand it. We can just ever get a limited amount of knowledge, while our ignorance will constantly stay limitless. This quote serves as a suggestion that, while we must strive to find out as much as we can, we must likewise accept that there will constantly be more that we do not know. It is very important to remain simple and unbiased, and to acknowledge that our knowledge is restricted.
