In the early universe, most matter consisted of hydrogen and helium.
These were formed immediately after the birth of the universe, and almost no other elements existed.
Changes Inside Stars
Inside the first stars, nuclear fusion reactions occur under conditions of high temperature and high pressure.
Through this reaction,
• Hydrogen is converted into helium
• Helium is converted into heavier elements
and so on.
In massive stars, elements such as
• Carbon
• Oxygen
• Neon
• Silicon
• Iron
are generated in stages.
Significance for the Universe
This process is not merely a change inside a star.
It is the process by which new types of matter, which did not exist in the universe until then,
are born into the universe for the first time.
Because of this, the universe begins to change
• From a simple composition
• To a world containing diverse matter
and so on.
Release of Elements
It is believed that at the end of their lives, the first stars undergo
• Supernova explosions
• Or direct collapse
events.
At that time, the elements generated inside the star are released into outer space.
Subsequent Effects
The released elements become the building blocks for
• New stars
• Planets
• Molecules
.
The diversity of structures and matter formed in the later universe depends on the elements created at this stage.
Summary
Nuclear fusion inside stars is
• A process that generates light, and at the same time,
• A process that creates new matter
👉
At this stage, for the first time, the universe becomes an entity that creates matter within itself.
