Certainly! Here are some more fascinating facts about the universe:

1. Expansion: The universe is expanding. This was discovered by Edwin Hubble in the 1920s, and since then, observations of distant galaxies have shown that they are moving away from us, indicating that the universe is not only expanding but doing so at an accelerating rate.

2. Size of the Observable Universe: The observable universe is the part of the entire universe that we can potentially observe. It spans a distance of about 93 billion light-years in diameter. This is because the universe has been expanding for billions of years, and light from the most distant parts of the universe has taken that long to reach us.

3. Composition: The universe is composed mostly of hydrogen (about 75%) and helium (about 25%) by mass. Other elements, including oxygen, carbon, nitrogen, and iron, make up less than 1% of the mass of the universe.

4. Age: The universe is approximately 13.8 billion years old. This age is derived from measurements of the cosmic microwave background radiation, which is the afterglow of the Big Bang.

5. Galaxies: There are billions of galaxies in the observable universe. Galaxies come in various shapes and sizes, from spiral galaxies like our Milky Way to elliptical and irregular galaxies.

6. Gravity: Gravity is the dominant force at cosmic scales, shaping the structure of galaxies, clusters of galaxies, and even the large-scale structure of the universe itself.

7. Cosmic Web: The large-scale structure of the universe resembles a cosmic web, where galaxies and galaxy clusters are interconnected by vast filaments of dark matter and gas.

8. Cosmic Microwave Background (CMB): The CMB is a faint glow of radiation that fills the universe, leftover from the Big Bang. It is a crucial piece of evidence supporting the Big Bang theory and provides insights into the early universe.

9. Black Holes: These are regions of spacetime where gravity is so strong that nothing, not even light, can escape from them. Supermassive black holes millions to billions of times the mass of our Sun reside at the centers of galaxies.

10. Time and Space: Space and time are interconnected in the fabric of spacetime. General relativity, Einstein's theory of gravity, describes how matter and energy warp spacetime, affecting the motion of objects and the passage of time.
