说明
这是2021年由PBS Space Time发布的一部讲解，主题归在Fundamental physics。它讲的是general relativity这一支里的具体问题，而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成：PBS Space Time explores whether time causes gravity, explaining that gravity does not truly warp the flow of time but arises from time gradients. It revisits how gravitational time dilation works in general relativity.这些读者给出的理由，核心是：Recommended as a good explanation of what happens when gravity acts on an object.讲法不绑某一条新闻，过几年仍然可以当材料看。从2021年到2023年，有1位不同的读者在1个不同月份把它推荐出来，其中明确叫别人去看的有1次。适合用一集把一个概念补上的人。抓住它用的那个图像或类比，比背公式重要。如果已经会了基本定义，就把注意力放在它怎么把general relativity变成能跟着复述的例子。
