If Helium is a more stable element than Hydrogen, then why wasn't just Helium formed during the process of nucleosynthesis? The matter could just have formed Helium. What was the thing that prevented it?
Helium is formed during nucleosynthesis when two hydrogen nuclei, or protons, fuse together to create a helium nucleus. This process, known as nuclear fusion, releases a large amount of energy and is responsible for the creation of all elements heavier than hydrogen in the universe.
Nucleosynthesis occurs in the cores of stars, where the high temperatures and pressures are conducive to nuclear fusion reactions. These reactions create new elements, including helium, which are then expelled into the surrounding space when the star dies.
Helium is the second most abundant element in the universe, after hydrogen. It plays a crucial role in the formation and evolution of stars and galaxies, and is also a key component of gas giant planets like Jupiter and Saturn. Helium is also used in various industrial and scientific applications, such as in cryogenics and as a coolant in nuclear reactors.
The process of helium formation during nucleosynthesis varies depending on the size and mass of the star. In low mass stars like our Sun, it can take millions of years for helium to form. In more massive stars, the process can occur much faster, in a matter of weeks or months.
While the majority of helium in the universe is formed during nucleosynthesis, a small amount can also be produced through radioactive decay of heavier elements. This process, known as alpha decay, occurs when a nucleus releases an alpha particle, which is essentially a helium nucleus. However, this contributes only a tiny fraction of the helium found in the universe.
