Explanation:
Detailed explanation-1: -Objects held together by gravity or other forces, including individual galaxies, individual stars and planets, and even ourselves, are not expanding. In fact, even the Milky Way and the Andromeda galaxies are gravitationally bound to each other, and therefore falling together, not moving apart.
Detailed explanation-2: -We know that light takes time to travel, so that if we observe an object that is 13 billion light years away, then that light has been traveling towards us for 13 billion years. Essentially, we are seeing that object as it appeared 13 billion years ago.
