问HN：在这份“物理学未解问题列表”中，有哪些问题引起了你的关注？
我今天刚刚在概念上理解了为什么量子引力是一个令人困惑的问题。我知道这个问题的存在，但由于我的数学基础非常有限，实际上并没有真正理解它。我依赖于概念理解来理解我周围的世界和物理学的问题。今天，作为外行的理解终于有了突破。目前，量子引力是我对我提问的答案。
我喜欢大脑中有东西突然明白的感觉。希望你也能有这样的体验！理解真是太棒了。

https://en.wikipedia.org/wiki/List_of_unsolved_problems_in_physics<p>I just today conceptually understood why quantum gravity is a perplexity. I knew the problem existed, but with a very limited mathematical background, did not really get it. I rely on conceptual understanding to comprehend the world around me and the problems of physics. Today the layman understanding clicked. As of right now, quantum gravity is my answer to my Ask.<p>I love when something clicks in the brain. Hope yours does the same! Understanding is sensational.
