All galaxies appear t/vsh4 db2j69d lw.xzp o v2hsgdw yrql;9 a43a6i gf*(abe moving away from us. Are we therefore at the center of th(92vfigywl6a r34sa *h; dgaqe universe? Explain.
参考答案: no
本题详细解析:
No, just because everything appears to be moving away from us does not mean we are at the center of the universe. Here is an analogy. If we were sitting on the surface of a balloon and then more air was put into the balloon causing it to expand, notice that every other point on the balloon is now farther away from you. The points close to you are farther away because of the expansion of the rubber and the points on the other side of the balloon are farther away from you because the radius of the balloon is now larger.
