为什么重力吸引物体？
1、重力是由质量引起的自然力，所有具有质量的物体之间都会产生这种吸引力。质量越大，吸引力越强。
2、根据牛顿的万有引力定律，两个物体之间的引力与它们的质量乘积成正比，与它们之间距离的平方成反比。
3、重力是时空弯曲的结果，根据爱因斯坦的广义相对论，质量会使时空弯曲，而物体则沿着弯曲的时空路径运动，表现为被吸引。
4、重力是地球和其他天体保持其形状和运动轨道的主要原因，例如地球上的物体总是被吸引向地心，导致物体下落。
5、重力不仅影响宏观物体，也影响微观粒子，例如电子被吸引围绕原子核运动，这是化学键和物质结构的基础。
总之，重力是一种基本的自然力，由质量引起，通过时空弯曲和万有引力定律作用，影响着从微观粒子到天体的所有物体。
