为什么引力吸引物体？
1、引力是宇宙中的一种基本力，由质量产生，所有有质量的物体之间都会相互吸引。
2、根据牛顿的万有引力定律，两个物体的引力大小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、爱因斯坦的广义相对论解释了引力是时空弯曲的结果，质量大的物体会使周围的时空弯曲，其他物体在弯曲的时空中运动时就会受到引力的影响。
4、引力不仅影响宏观物体，如行星和恒星，也影响微观粒子，如电子和质子，是宇宙中物质结构和运动的基本驱动力。
5、引力是自然界中四种基本力之一，其他三种是电磁力、强核力和弱核力，它们共同作用形成了我们所知的宇宙。
总之，引力是质量与质量之间的相互吸引作用，由时空的弯曲和物体的质量决定，是宇宙中物质结构和运动的基本原因。
