Where does the dust in the universe come from? Why does dust turn into a planet?

First of all, thanks for the invitation. Our universe was born 13.8 billion years ago, and if it weren't for that big **, the world would no longer exist today, and you and I would not have existed. Space is a silent world, even in the vacuum of space, there are many things you can't see, such as the space dust we mentioned, how is space dust formed?

How did it form the planet? Let's break it down.

Today we know that the earth is just a drop in the ocean in the universe, even the sun is just that, and our universe is full of dust, in fact, most of this dust is mostly gas, and the other part is what we call matter. Gases are well explained because they have existed for very, very long periods of time and their lifespans even extend beyond the entire solar system.

These are hydrogen clouds, and they were born in the universe.

After 380,000 years!

The other part of the dust is the matter we mentioned, the age of the universe is 13.8 billion, and our sun belongs to the second generation of stars, which means that the first generation of stars has died. The first generation of stars died by supernova explosions.

In the event of death, under the action of gravity, the hydrogen gas will condense.

Gravity is the smallest of the four major forces in the universe, although it has the smallest effect, but even the smallest atoms, and subatoms have mass, so they will have gravity and attract each other. This also explains why hydrogen coalesces, which in turn produces nuclear fusion.

The reason for the birth of stars.

When a star dies, a supernova explosion is released, during which a large amount of material is released, and this material continues to spread outward as the universe expands. The temperature of the universe is very low, reaching minus 270, so these substances gradually cool down, and then evolve into small particles and debris in space, which we collectively call these particles and gas dust space dust! Don't underestimate space dust, it's their combination that has made the Earth what it is today!

The dust in the universe comes from the hollow, and then slowly gathers together to form planets, but this process is relatively long.

Our universe originated when it exploded 13.8 billion light-light-years ago, and without that explosion, the world would be wiped out today and would not have appeared with each other. Outer space is a silent world, even in the space of the vacuum pump, it has a lot of things you can't see, just like the dust we mentioned, what does the dust in the universe come from? Why did dust turn into planets?

The earth is just a drop in the ocean in the universe, even the sunlight is just that, our universe is distributed with dust, in fact, most of these dust is mostly vapor, and the other part is what we call chemicals. The vapour is easy to explain, because it existed for a very long time, and their lifetime even exceeded that of the entire solar system planets, which are radon clouds, which originated 38 tens of thousands of years after the expansion of the universe!

The other part of the dust is the chemicals that everyone mentioned, the age of the universe is 13.8 billion, and our sun belongs to the second generation of planets, which means that the first generation of planets is dying. The first generation of planets died in the form of supernova explosions, and under the influence of attraction, radon gas condensed. The attraction force is the smallest of the four interacting forces in the universe, although it has the least function, but even the smallest molecule, and the secondary molecule have quality, so it will cause the attraction and cause the effect of mutual attraction.

It is also the main reason why radon gas condenses, which in turn causes controlled nuclear fusion to emerge planets.

When a star dies, a supernova explosion is released, during which a large amount of chemicals are released, and this material continues to spread outward as the universe expands. The temperature of the universe is very low, reaching minus 270, so this material is slowly cooled, and then evolves into particles and debris in space, which is commonly known as the dust of outer space! Don't underestimate the dust of outer space, it just so happens that their fusion makes up today's Earth!

"Dust in the universe is mainly produced by celestial bodies that can eject matter, such as stars and galaxies. Just as dust in the solar system is mostly made up of material carried by the solar wind. The sun rotates at high speed while revolving around the galactic center, and a large amount of material is often ejected from the surface of the sun near the equator to form the solar wind.

According to astronomical observations, the solar wind can reach as far as the edge of the solar system. At the center of the galaxy is supposed to be a much larger jet of matter, with its two spiral arms formed by its ejecta.

The dust in the universe is caused by the impact of meteorites; Because they all have a certain attraction, they will gradually absorb matter and slowly transform into planets.

It is mainly generated from the centers of some galaxies. Because the universe is made up of countless dusts, and there is a core inside the planet.

The planets we live on are made up of massive amounts of cosmic dust, but where does the cosmic dust come from? British scientists are unraveling the mystery: supernovae, supermassive stars that are ****, could be a large ** of cosmic dust.

Scientists have long believed that cosmic dust first forms in relatively low-temperature, slow-burning ordinary stars and is then released in the form of solar wind. However, Locke Hortha Dunn, an astronomer at Cardiff University in the United Kingdom, and others have discovered that some supernovae are capable of ejecting large amounts of dust, which is a large number of solid particles in space. x0d Dunn and his colleagues at the Royal Observatory used a special telescope to make submillimeter observations of the youngest known supernova in the Milky Way, Cassiopeia-A (10,000,000 light-years from Earth, 10 trillion kilometers).

They found that there was a large amount of cold dust in the remnants of Cassiopeia, which may have a mass of four times the mass of the Sun. Dunn argues that if all supernovae emit a lot of dust like Cassiopeia, then supernovae are better dust makers in the galaxy than the solar wind. x0d Since supernovae "evolve" faster than ordinary stars, the first cosmic dust may have been the "masterpieces" of their Janes

"The dust we see 10 billion years ago or even earlier may all come from supernovae," Dunn said

Introduction: There is a lot of matter in the universe, there is a nebula in the universe, nebula actually refers to the largest cloud of ionized gas and dust There are three types of nebulae in the universe, the first is the remnants left after the explosion of some superplanets, when a huge mass of star fuel is exhausted, it may be **, and then**, it may become a neutron star, or it may become a black hole, and a large amount of gas is scattered around this star, These gases form nebulae. There are also planetary nebulae, which are also formed by some stars that are about to die, because all stars will face birth, old age, sickness and death, and when these stars do not become supernovae, because they do not have enough energy, the matter on the stars will fall, but these materials will form dense objects and scatter.

The gas that comes out forms planetary nebulae. Nebulae mainly refer to the size and solar system formed by the dust and gas of stars in the universe.

is about the same, and the mass has the potential to form a new star.

The shape of the nebula is colorful, there is a certain relationship between the nebula and the star, and the nebula is also divided into diffuse nebulae by some classifications, these nebulae have no obvious boundaries, and they also show irregular shapes, and their display in the universe is like a slippery cloud in the sky, which needs to be observed through a telescope. Diffuse nebulae are generally distributed on the surface of the galactic road, and the more famous nebulae include the Orion Nebula and so on. There is also the launch nebula, the more famous being the constellation Cygnus.

The North American Nebula will have some dark spots because the dust in the clouds blocks the light.

In fact, there is a special nebula, which is supernova remains, which is a supernova explosion.

Formed by the ejected gas, the volume of this type of nebula is generally in a state of expansion, and when it reaches a certain point, it will begin to dissipate.

In the end, there will be a lot of things in the universe, which human beings do not know enough at present, and they cannot detect all the things in the universe.

The nebula is a structure composed of some dust in the sky and some gas in the interstellar void spring. The relationship with it is a necessary connection, because the dust in the Vonai universe makes up the nebula, so the connection is very close.

Nebulae are a kind of substance that exists in the universe, nebulae are composed of some water vapor, and there are also dust in the universe. Nebulae and dust float in the universe.

Nebulae refer to the combination of some dust and some guessing planets and stars in a chain, and cosmic dust has a direct relationship with it, and most nebulae contain cosmic dust.

The knowledge of the formation of the universe is a very wonderful thing, and how our universe was formed, many scientists have been trying to explore the reasons for this. But nowadays, many scientists agree with the view put forward by Stephen Hawking, about the theory of the universe, he proposed that the universe has a singularity, which happened. The theory of the universe has been recognized by many scientists today, so where does the dust in the universe come from?

Why does dust turn into a planet? The reasons for this are as follows. <>

1. The dust comes from the energy component that erupted at that time in the universe. First of all, the first point is about dust, which comes from some waste produced by the singularity of the universe at that time. These fine substances become fine dust when they are impacted by the energy of various high-pressure substances.

This dust permeates all parts of the universe, and some of them are bigger than our fingers and some are bigger than our present earth. Including the fact that we now have all this dust around the earth, not around our whole life. <>

2. Formation of planets. Secondly, it's about how exactly this dust forms the planet. In fact, these dust can form planets precisely because there is a core inside the planet.

This core obviously has a certain attraction psychology, which can attract the surrounding city dust, and it has a certain attraction inside, such an attraction can attract the surrounding dust, converge to it, drift through time, and drift with the waves in various places in the universe, so as to form a planet. <>

3. The formation of the planet is always full of complexities. The last point is that the formation of the planet is full of complex phenomena. Because the actual age of the planet is older than anything we know.

And if we humans want an actual trip to the planet, we must know the core, but at present, we humans do not have an obvious technology to explore the core.

The dust in the universe is because of the waste products produced later by the planets in the universe, and they are scattered in the universe. There is a core inside the planet, and these cores can attract the dust in the universe, so that it can slowly come together, and after a long, long time, and then form a new planet.

The dust comes from the energy components that erupted at that time of the universe, and then these dusts can form planets precisely because there is a core inside the planet. Obviously, this core has a certain attraction psychology, which can attract the surrounding city dust, and it has a certain attraction inside, such an attraction can attract the surrounding dust, converge to it, drift through time, and drift with the tide in various places in the universe.

Dust This is some waste produced by the singularity of the universe at that time, and there is a core inside the planet. This core has a certain attraction, which can attract the surrounding dust and merge into it, so as to form a planet.

Cosmic dust is a star** or after a collision But for various reasons, this dust does not coalesce into a star, but is suspended in the form of particles in the cosmic space. His composition is similar to that of Earth, so it can form planets.

Cosmic dust is an important extraterrestrial substance used by human beings to study various information in space. Because it is so small, like a wheat, humans have never seen it fall before their eyes. However, the amount of this extraterrestrial material is staggering.

According to the research and testing of relevant experts, the annual precipitation of cosmic dust with a particle size greater than 60 microns is about 23,430 tons. What is particularly amazing is that the structure of cosmic dust chondrites is the same as that of the Earth, with a triple structure of core and mantle crust, and the core radius of each chondrite is greater than the thickness of the mantle and the thickness of the crust, and the average thickness percentage between them is: 46 and.

Its ratio is similar to the percentage between the thickness of the Earth's core, mantle, and shell. Scientists are intrigued by this striking proximity, as the tiny speck of cosmic dust resembles the structure of the Earth. Cosmic dust, there are roughly three types:

One is black or brownish black in appearance, and the surface is bright and dazzling, very much like a shiny small steel ball; The second is dark brown or slightly grayish-white spherical, ellipsoidal, rounded small particles, the main components are oxygen, silicon, magnesium, calcium, aluminum, etc.; The third type is some colorless or pale green glass spheres, the main component is silicon dioxide, and also contains a small amount of divalent oxide. This cosmic dust is part of the interstellar dust before it falls on Earth. As they reflect the sun's rays, a blurred band of zodiacal light is formed.

Over millions of years, dust particles have been rotating towards the Sun and replenishing from the asteroid belt. As for the cause of these cosmic dusts, researchers at the University of Bath in the United Kingdom believe that they are sparks thrown by asteroids when the cosmic space between Mars and Jupiter collides with each other, and most of them fall to the deep seabed. The chemical composition of these small particles is very different from that of deep-sea sediments and has a unique shape.

In 1872, the British oceanographic research ship "Challenger" was on an expedition and first picked up this strange small particle from the deep seabed; The United States in 1950, Japan in 1967, and China in 1978 all collected these small particles at the bottom of the ocean. In order to study their composition, scientists from various countries have carried out a lot of work, comparing them with the cosmic dust collected at high altitude by high-altitude balloons, rockets, artificial satellites, and other aircraft, and found that the two are identical, thus determining that these small particles are cosmic dust from the earth. As for the green vitreous dust particles, some scientists believe that they come from the moon and are eruptions of lunar volcanism, and their properties are exactly the same as those of the vitreous material found in lunar soil.

The study of cosmic dust in the depths of the ocean is of great significance for the origin and evolution of the earth, the solar system and the Milky Way, however, there are still many mysteries of cosmic dust to be solved.
