What is the “neutron star” that created heavy metals such as gold and platinum in the universe?

A star is formed by the innumerable plasma that is attracted to the center by gravity.
Stars, which are celestial bodies of gas bodies that emit light, such as the sun, undergo a reaction between atoms due to pressure inside. One of them is that
As long as the outward pressure and the inward pressure are balanced, the star is in a stable state.
However, for stars that are much larger than the sun, there are cases where problems appear on the inside even though they appear to be stable.
After the reaction that turns hydrogen into helium 4, the outward pressure due to the released energy drops, so the inward pressure due to gravity prevails. Due to the inward force, the size of the star itself becomes smaller.
As a result of the increased pressure, the burning temperature and speed of the stellar core increased. Then, carbon becomes neon in the core, neon turns into oxygen, oxygen turns into silicon, and finally iron.
The reaction ends when the star's core is all iron, and the outward pressure due to the released energy is zero. When the outward pressure becomes zero, the inward force due to gravity continues to be applied to the core.
Normally, particles such as electrons and protons maintain a certain distance from each other by
However, if gravity increases, it will be pressurized so that a certain distance cannot be maintained.
As for the pressure, the stellar core of the same size as the Earth is compressed to the size of the city.
This pressure causes the outer edge of the planet to shrink inward at a rate of 25% of the speed of light and eventually explode.
The iron in the core is scattered into the universe by the explosion. This phenomenon is called “supernova”. The light emitted by the supernova is strong enough to illuminate the entire universe.
And what remains after the supernova is the neutron star in question.
The mass of a neutron star is one million Earths ...
Its volume is only as much as a cube with a side of 25 km.
Therefore, the gravity of neutron stars is the second strongest in space after black holes. The light that crosses the vicinity of the neutron star is bent in the direction of travel due to its gravity.
Furthermore, the surface temperature of neutron stars reaches 1 million degrees Celsius. The surface temperature of the sun is 6000 ° C.
Neutron stars consist of three layers: the atmosphere, the crust, and the core.
The earth's crust boasts tremendous hardness when the iron remaining from the supernova is
In the middle of the earth's crust, iron atoms are believed to adhere linearly and further to the inside. The iron atom bonded linearly is called “spaghetti”, and the iron atom bonded in layers is called “lasagna”. The crust of a neutron star is called “
This nuclear pasta has the highest hardness in the universe, and is basically considered to be a “non-breakable substance”.
Inside the pasta is the core of the neutron star.
Protons and neutrons are decomposed in the core of the neutron star, and it is expected to be in the state of “
There is a theory that quark gluon plasma can produce “strange matter” which is the most dangerous substance in the universe.
For a detailed explanation of strange substances by Kurzgesagt, see the following article:
When a neutron star collapses, the neutron star rotates at high speed like a ballerina.
This high-speed rotation and the magnetic field of the neutron star combine to produce a huge radio wave. Neutron stars in this state are called “
The magnetic field of Pulsar is 1000 trillion times stronger than the Earth's magnetic field.
It is also known that two neutron stars merge to cause a large explosion called
Eventually, the two neutron stars that caused Kirova are black holes.
Various materials were sprinkled in outer space by supernovae and Kirova. This material is attracted by each other's gravity and becomes a star or planet. And a neutron star is born again from a star.
The science and technology used in modern society is also based on elements created by neutron stars long ago.
The neutron star created the present world.
