Hi Burning Clown, that’s a very interesting question and I’m afraid I don’t know the details but I can tell you that the universe is thought to be made of three kinds of substances: normal matter, ‘dark matter’ and ‘dark energy’.
Normal matter are the atoms that make up stars, planets, and living things. Basically everything we can see or observe. This normal matter makes up only the smallest percentage of the Universe (like 1 to 10% only). Don’t ask me about dark matter or dark energy because no one is sure about what that is. But an astrophysicist might be able to help you better. If you figure it out, let me know 😛
