WebIn the early years, everything was made of gas. This gas, mostly hydrogen and helium, expanded and cooled. Over billions of years, gravity caused gas and dust to form galaxies, stars, planets, and more. The matter that spread out from the Big Bang developed into everything in the universe, including you. You are made of star stuff! WebJan 3, 2024 · Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula – a spinning, swirling disk of material.

(See figure on the formation of Helium-4) Learn about it! For the first three minutes, a substantial amount of neutrons was converted into helium-4 nuclei, before their decay. Helium then combined to other nuclei to form heavier ones such as lithium-7 and beryllium-7.

WebHelium is the smallest and the lightest noble gas and one of the most unreactive elements, so it was commonly considered that helium compounds cannot exist at all, or at least … WebDeuterium further fused into helium-4. These ionized atoms of hydrogen and helium attracted electrons turning them into neutral atoms. Ultimately the composition of the universe at this point was 3 times more hydrogen than helium with just trace amounts of other light elements.
