The universe and human stupidity are infinite-Einstein means: the universe is infinite, and human's understanding of the universe and everything is very small compared with the universe. As long as the universe is infinite, we humans still have a lot of things we don't know, just like watching primitive people is stupid today. If human beings develop in the next 1 years, 1 years and 1 years, I believe we will be stupid at that time. So as long as there is no end to time, there will always be a lot of unknown knowledge and exploration, just like Columbus discovered the new world, Newton's apples and so on. As long as the universe is infinite, there are many blind spots for human beings, so the relative stupidity of human beings exists.
