The Bible does not explicitly state a scientific reason for why the universe is held together. It focuses on the creation and purpose of the universe from a theological perspective.

However, you might be interested in the following verses that speak about God's power and control over the universe:

* Colossians 1:16-17: "For by him all things were created, in heaven and on earth, visible and invisible, whether thrones or dominions or rulers or authorities—all things were created through him and for him. And he is before all things, and in him all things hold together."

* Hebrews 1:3: "He is the radiance of the glory of God and the exact imprint of his nature, and he upholds the universe by the word of his power."

These verses emphasize that God's power and authority maintain the universe's existence and order. While they don't give a scientific explanation, they offer a theological perspective on the universe's stability.

It's important to note that the Bible is not a science textbook. It primarily addresses spiritual and moral matters, not scientific explanations of the universe.
