Does the concept of space refer to the Milky Way?

Nobody knows. Space is called space because people used to see places outside the earth that were dark and empty, so they were called space. To put it bluntly, it's a word.

The Milky Way is a galaxy, and there are many galaxies outside the Milky Way, called extragalactic galaxies, and what contains them is the universe, which is generally believed to be boundary, but it is too big to be recognized at present. There is a lot of speculation, such as twin universes, that there are two universes that exist in parallel. The space outside the total galaxy you are talking about may not be measured by the concept of space at all, and human beings can only see things within three dimensions at most.

For example, if your cognition is limited to a straight line, then you can't see the "space" outside the straight line. As for what is beyond the universe, no one knows, maybe it's still the universe, just like there are galaxies outside the galaxy.

The stars you see with the naked eye at night are galaxies as massive or larger than the Milky Way, and the universe is vast. The solar system is just a general term for planets including the sun, planetary moons, asteroids, and comets. The solar system is in the Milky Way, and the Milky Way is in the universe; There are no total galaxies, because with the current level of technology, there is no understanding of what the universe is, let alone studying it.

As far as the existing scientific data and scientific and technological theories are concerned, they are only valid in the solar system or the earth, and they are all wrong or untenable. Science is not a result, but simply a general term for the process of finding and correcting mistakes. As for your so-called "total galaxy", you have never heard of it, and as for whether there is space beyond the universe, it is impossible to answer with the current level of technology on Earth.

There's a bigger sky beyond the Milky Way!! There are many, many galaxies that resemble the Milky Way.

Space is a whole concept, to be precise, the space where you and I are located is a whole!

To put it simply, the concept of space is that the space where more than 20 million galaxies are located is space, or the standard interpretation is "a huge container that holds all that is known" is space.

There are not only the Milky Way and the Solar System in the universe, but the Milky Way and the Solar System are two planets of different gradesThe solar system is a galaxy of stars alone; The Milky Way is composed of 100 billion stars, and naturally in addition to stars, the Milky Way also contains all types of stars in the universe, including neutron stars and black holes. The Great Theory of the Universe is aimed at how the universe was established, and the most popular view at this stage is the Great Theory of the Universe.

The universe was created by the expansion of a hot infinitesimal singularity 13.7 billion light years ago, and the universe is expanding at an accelerated rate, and the planets in the universe are getting farther and farther away, and the middle of the planets is becoming more and more scarce. After the cosmic explosion, the universe was filled with clouds of gas remnants of the explosion, and in some areas there were viscous interstellar imperial vapors, most of which were hydrogen and helium, and millions of stars were generated by the attraction of massive gas clouds. Most of the original stars were super-large, massive.

Their ambient temperature is extremely high, and they ignite quickly, causing a large number of black holes after deflagration. The attraction pulls together many black holes, and in the early universe they join together to create larger black holes. The large black hole gradually merged to produce a super-large black hole, and in the scope of attraction of this super-large black hole, it gradually attracted a lot of cosmic vapor star orbits, which turned into billions of stars in the process of rotating around the black hole, giving rise to the first planet.

The Milky Way is a flattened galaxy, called a barred spiral galaxy, that is, a spiral shape, and there are also planets that are oblate and round. With an aperture of about 15-200,000 light-years, the solar system is located in the Milky Way, and it is obvious that planets like the solar system are very common in the Milky Way, and many of them are like gravel in the desert. The solar system is a single star planet, and most of the Milky Way systems exist in binary and three-star systemsIt is the attraction effect of this multi-star system software that sends gravitational waves outward.

In addition to the Milky Way and the Solar System, there are hundreds of billions of other galaxies in the universe, collectively known as extragalactic galaxies.

There are other galaxies, which can be more than 1 billion, such as the Andromeda Galaxy, the Large Magellanic Galaxy, the universe is very large and beautiful, and the appearance of each galaxy is different.

Both the Milky Way and the Solar System refer to some type of celestial structure, with the former being a star system and the latter being a planetary system.

Space is not a celestial structure, but a spatial scope, which generally refers to all space outside the earth's atmosphere, including other cosmic objects in space, so space is not "empty".

In space, a system in which one or more planets (including their moons), asteroids, comets, and dust debris revolve around the central star and are attracted by the strong gravitational pull of the central star, called a planetary system.

Our planetary system consists of eight planets (including Earth's own discovered moons, five dwarf planets, a comet (Halley) and hundreds of millions of small bodies. Together with the central star, the Sun, they are known as the Solar System.

In space, many stars, planetary systems, nebulae, and cosmic dust are attracted by the strong gravitational pull of the central black hole, forming a collection of celestial bodies with an "island" structure, collectively known as the star system.

The Milky Way is a star system with about 400 billion light stars, and the Sun is one of them.

Of course, there are more taxonomic names in astronomy than the Milky Way. The sequence is subgroups of galaxies, local groups of galaxies, superclusters (subdividable), whole galaxies, Hubble volumes, and the universe.

As for the solar system, this huge galaxy is considered familiar to everyone. Without the solar system, there would be no humans. The solar system is a small galaxy where the Earth and other galaxies are located.

The realm of the solar system includes the Sun, four Earth-like inner planets, an asteroid belt of many small rocks, four giant outer planets filled with gas, and a small region of celestial bodies filled with frozen small rocks known as the Kuiper Belt. The solar system accounts for 99% of the mass of the sun, and the diameter of the sun is about 700,000 kilometers, which is the source of the solar system, so the sun is the core of the solar system.

Therefore, the Sun is just an ordinary small-mass star in the Milky Way. There are hundreds of billions of sun-like stars in the Milky Way. The Milky Way is just one of hundreds of billions of galaxies in the universe.

There are hundreds of billions of star systems the size of the Milky Way in the observable universe, and these star systems exist in space. Together, these hundreds of billions of galaxies make up our observable universe.

The closer you are to the sun, the stronger the effect. So Pluto and a number of other distant objects that cross Neptune in and out of the Kuiper Belt are orbiting farther and farther away from the equatorial plane and the Sun. Ultimately their orbits are completely random in this regard, like long-period comets.

Both the Milky Way and the Solar System refer to some type of celestial structure, where the Milky Way is a star system and the Solar System is a planetary system. The solar system and the Milky Way are subordinate, and the Milky Way contains the solar system. These star systems are all contained in space and together make up our observable universe.

Both the Milky Way and the Solar System refer to certain types of celestial structures. The former is a stellar system and the latter is a planetary system. Space is not a celestial structure, but a spatial scope, which generally refers to all space outside the earth's atmosphere, including other cosmic objects in space, so space is not "empty".

In space, a system in which one or more planets (including their moons), asteroids, comets, and dust debris revolve around the central star and are attracted by the strong gravitational pull of the central star is called a planetary system.

The difference between the Milky Way, the Solar System and Space is that they refer to different ranges, the Sun is part of the Milky Way, and there are many galaxies in the Milky Way that are similar to the Solar System, while the Milky Way is a part of the universe, and there are many Milky Ways in the universe.

The Milky Way is larger than the solar system.

The Milky Way consists of 1000 400 billion stars and a large number of star clusters, nebulae and various types of interstellar gas and interstellar dust. With a total mass of about 210 billion times that of the Sun, it belongs to the local group of galaxies, and the nearest extragalactic galaxy is the Dwarf Canis Major galaxy, 42,000 light-years away.

The Milky Way is an oblate sphere with a massive disk structure consisting of a bright and dense core, two major spiral arms, and two unformed spiral arms, which are 4,500 light-years apart. The Sun is located on the Orion Arm, a branch of the Milky Way, and the distance from the center of the Milky Way is about 10,000 light-years.

The solar system is a collection of celestial bodies centered on the Sun and subject to the Sun's gravitational constraints. It includes eight planets (in descending order from closest to the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune) and at least 173 known moons, five identified dwarf planets, and hundreds of millions of small bodies in the solar system.

Broadly speaking, the realm of the solar system includes the sun, four inner planets like the Earth, an asteroid belt made up of many small rocks, four huge outer planets filled with gas, and a second small celestial region filled with small frozen rocks known as the Kuiper Belt.
