• Dark objects: they are dark parts which it is unknown until the present time, but it is believed that they represent more than a quarter of the universe.

• In the beginning, the universe was a mass that exploded, which led to the formation of subatomic particles, which gathered again and formed the stars and celestial bodies and the rest of the parts of the universe that exist now.
• The universe includes outer space with all its contents of moons, stars, galaxies, planets, and comets.
• Watch also:  The universe is expanding from the moment of the Big Bang to today

Finally, we have answered the question How old is the universe?  We also learned about the most important information about the universe, as well as the various theories that explained the origin of the universe, as well as the most important facts about it, and much other information on this subject in detail.
