Why are there so many low mass stars in the universe?

As for the starry sky in which we now live, this is very vast, and we used to think about how many stars there would be in this sky when we were children, and whether we could count them is a big question that plagued us when we were children. As we get older, we find that this starry sky has as many stars as all the sand on our planet combined. Scientists have recently made the following conclusions: why are there so many low-mass stars in the universe we live in now with about 2,000 billion galaxies?

1. Some of the wreckage produced by the universe at that time. First of all, the first point is about some of the debris produced by the universe at that time, about these debris are large and small, but with the change of time, these debris of different sizes are slowly affected by some traction and regrouped together. These condensed meteorites, or some other planetary debris, make up some of the low-mass stars we know today.

And these low-mass stars are also relatively special, and some of them can also emit light, such as Sirius, which we know, and Ophiuchus. <>

Second, a collision between large planets will also tear more debris apart. There is also a collision about a large planet will also tear out more debris, about our scientists now predict that the nearest and largest galaxy from our galaxy is the Andromeda Nebula, this galaxy is about 2 million light years away from our galaxy, and every year it will be as close to 200,000 kilometers as our galaxy, one day the Andromeda Nebula will crash into our galaxy, and after hitting our galaxy, it will tear out some larger star fragments. <>

Third, there are also some that are affected by black holes. Finally, there are some planets that are attracted by the large size of the black hole, and directly inhale into the black hole, and directly turn into debris and debris, and may become some of the smaller stars we know now.

Because the matter in the universe is more dispersed, it is easier for small-mass stars to form, so there will be so many small-mass stars in the universe.

Because the collision of some planets in the universe will produce debris, and these debris will recondense in the universe to form small mass stars.

The small planets created by the collision of meteorites slowly find their own orbits to survive and form a colorful starry sky.

The most massive star ever discovered is the R136A1 star, which is a Wolf-Layet star, the most massive star known in the list of massive stars. The largest star in the universe. It is 5 billion times the size of the Sun and only 32 times the mass of the Sun.

The most massive star known is R136A1, which is about 265 times the mass of the Sun.

R136A1 is the largest known star in the universe, about 265 times the mass of the sun, such a huge mass, obviously more than most stellar black holes, most of the stellar black holes are between 3-100 times the sun, we all know that the gravitational pull of black holes is very strong, so that light can not escape, but although the mass of r136a1 exceeds many black holes, the light it emits is constantly shooting into the depths of the universe, So much so that it became the brightest known star (8.7 million times the luminosity of the sun), so why does R136A1 have such a huge mass that it can still let its own light shine?

<> fact, the reason is not complicated, although the mass of R136A1 is huge, but its volume is also very large, the diameter of this star is equivalent to the sun, and the volume is equivalent to about 33,000 times that of the sun, so it seems that it is equivalent to 265 times the mass of the sun, and the material is scattered into the space of 33,000 times the volume of the sun.

Here we can make another analogy, if a massive object like the Sun is compressed into a black hole, then its event horizon volume will only be about 6 kilometers in diameter, but the actual diameter of the Sun is as high as 1.39 million kilometers, which is why the Sun does not absorb its own light, that is, its density is not large enough, the density of matter is not dense enough, and the gravitational field is not strong enough to make it difficult for light to escape. Since even a dense object as large as the Sun cannot absorb light, it is even more difficult for a less dense object like R136A1 to absorb the light it emits.

In fact, the density of our earth is much larger than that of the sun and r136a1, but the mass and density of the earth are far from becoming a black hole, and if the earth becomes a black hole, then its volume is less than two centimeters in diameter (disproportionate to the size of the sun becoming a black hole), it is hard to imagine that the density of such a black hole will be so high!

Personally, I don't think the bigger the better, it's a matter of fact.

At present, the farthest vision of human beings can only extend to the edge of the universe, and whether there is a universe or parallel universe similar to ours beyond the edge of the universe, and if there is a parallel universe system outside the parallel universe, human beings may not be able to solve this mystery so far or in the future. The largest known star. Let's say there are 10 billion people on the planet.

It is known that the sun is 1 million times larger than the earth, and the big dog vy is 8 billion times larger than the sun. That's 800 million people. The earth is like a bacterium.

In order to know the size of the largest star in the known universe, we can first know the closest star to Earth, the Sun. The average distance between the Earth and the Moon is only 380,000 kilometers. In terms of volume, the Sun can hold nearly 1.3 million Earths.

It can be seen that the size of the sun is quite large. However, the size of the Sun is insignificant compared to the largest known stars in the universe. Currently, the largest star discovered is UY Shield, a red giant located about 9,500 light-years from Earth.

It has been calculated that the diameter of UY is up to 100 million kilometers, which is equivalent to 1,708 times that of the sun. You know, the average distance from the Earth to the Sun is about 100 million kilometers, which is only one-sixteenth the diameter of this red giant.

In terms of volume, the UY shield can hold nearly 5 billion suns and 6,500 trillion earths. Given its enormous size, it takes hours for light to travel around the equator of the UY shield and seconds to travel around the equator of the Sun. If it were a spacecraft with a speed of kilometers per second, it would take about 30 years to fly around the UY equator.

If it is an airplane with a speed of 900 kilometers per hour, this time is about 946. As a giant red giant, the UY shield has a hard time binding matter to its surface. The star may have lost more than half of its mass since its birth.

Due to its sheer size, S.H.I.E.L.D.'s UY has a fast nuclear fusion reaction, and it quickly runs out of nuclear reaction fuel. It is estimated to have a lifespan of only a few tens of millions of years (the estimated lifespan of the Sun is about 10 billion years). At the end of its evolution, it violently** becomes a supernova, and its center collapses into a black hole.

Shield seat UY.

UY is a red supergiant located in the constellation Shield. It is considered one of the largest known stars and at the same time a pulsating variable star. Its radius is estimated to be 1,708 solar radii (100 million kilometers, about astronomical units), so it is nearly 5 billion times the size of the Sun.

It is about 2,900 parsecs (about 9,500 light-years) from Earth. If it is placed in the position of the Sun, its photosphere will at least engulf Jupiter's orbit and may approach Saturn's orbit. The largest known star is Stevenson 2-18 (2.9 billion km) located in the Milky Way.

It's the sun. The Sun is the largest star in the Milky Way and the largest known in the universe, hundreds of times the size of the Earth.

At present, Stevenson-218 (the author will not write) is not the Shield Uy, the largest star before 2016 was Canis Major, but later the calculation method was improved, and then the largest is the Shield Uy, (in fact, people have found the Shield Vy before, but people's calculation methods are not accurate, it seems that Canis Major VY is bigger than the Shield Uy, but in fact the Shield Vy is larger than the Shield Y Major) and then found the Stitch tattoo -218 He is bigger than the Shield Y again, But we don't know if there will be bigger stars in the future, but there will be, after all, we don't have a W-type star yet.

Currently, the largest star ever discovered is the shield UY, which is 12,000 times larger than the Sun. It takes more than 9 hours for light to orbit this star, which is much larger than eight. It takes half a minute for sunlight to reach the ground.

The most massive planets in the universe are those located in the center of galaxies.

A team led by Ma Zhongpei, a Chinese-American astronomer at the University of California, Berkeley, recently discovered two of the largest black holes known to science. They are located in the NGC 3842 and NGC 4889 galaxies, respectively, and each has a mass about 10 billion times that of the Sun.

Quasars are the largest if they are counted as spheres. The mass is a billion times that of the sun.

In the normal sense, a black hole is a star that collapses and condenses. Except for quasars. Black holes are also massive stars! The black hole at the heart of the Milky Way, which hosts the galactic balance stabilizer, is millions of times more massive than the Sun.

White dwarf. The volume is minimal. The density is amazing.

A white dwarf is a low-luminosity, high-density, high-temperature star. Because of its white color and relatively small size, it was named a white dwarf. A white dwarf is a late star.

According to modern theories of stellar evolution, white dwarfs form at the center of red giants. White dwarfs are a very special kind of celestial objects, which are small in size and low in brightness, but have large mass and extremely high density. For example, Sirius companion star (it was the first white dwarf to be discovered) is about the size of the Earth but about the same mass as the Sun, and its density is about 10 million tons of cubic meters.

Black holes, if they can be classified as planets.

I have measured that the mass of the universe is equivalent to a basketball.

The universe is too big to calculate.

The Sun is our closest star, and its large belly can hold 1.3 million Earths. However, there are more stars in the universe than sand on Earth, and the Sun is just an ordinary member.

The largest star.

Canis Major is the largest known star, and the Sun is like a drop of water facing the entire ocean. The volume of the star VY Canis Major is about a billion times that of the Sun. The star VY Canis Major is very bright, its luminosity is more than 500,000 times higher than that of the Sun.

Still, we can't see it with the naked eye because it's so far away from us, and there's a lot of interstellar dust in between. For stars, growing too big is not necessarily a good thing, and the star VY Canis Major is spewing out a lot of gas at an alarming rate, and it is likely to die out in 100,000 years by way of supernovae**.

The heaviest star.

The star R136A1 is currently the heaviest known star, at a distance of about 10,000 light-years from the Milky Way. At the time of its birth, it was more massive than it is today, about 320 times the mass of the Sun. Because heavyweight stars release more energy, R136A1 consumes 20% of its mass in just 1 million years, and now it is equivalent to 265 suns in rapid progress.

The "**" of R136AL is actually involuntarily, and stars like it tend to be short-lived ghosts due to the great loss of mass. R136A1 glows blue and is very dazzling, about 10 million times brighter than the sun.

We must know that the development of human science and technology is still very limited, and we know very little about other stars except our neighbor Sun, and it is inevitable that there will be errors only by relying on long-distance observation and calculation, and the theory that the largest size of the VY major star has always been controversial. One view is that it is just an ordinary red giant, only 600 times the diameter of the Sun. Some scientists believe that the star VY Canis Major is far less bright than most people think.

The astonishing mass of the star R136A1 has also raised many suspicions. An astronomer at the University of California believes that the R136A1 we observe may be a "twin star," meaning that R136A1 is not a single star, but two stars with similar mass.

Do you know? There are so many stars in the sky that if they collide together, what will happen? Don't be afraid.

If the planets in the universe are very close together and move in a chaotic manner, maybe they will collide with each other, but in reality the planets are very far apart, and each planet has its own orbit, so the possibility of them colliding is very small.
