What is on the outside of the Earth? What is beyond the earth

Outside the Earth is the Earth's atmosphere, which is a complex and multi-layered gasosphere that can extend to an altitude of more than 1,000 kilometers above the ground. The main components of the atmosphere are gases such as nitrogen, oxygen, argon, etc., but also small amounts of other elements and compounds. The atmosphere has an important impact on the earth's weather, climate and ecological environment.

In addition to the atmosphere, the Earth is surrounded by other celestial bodies in the solar system, including the Sun, the eight planets, moons, and asteroids. These celestial bodies revolve around the Sun in orbit in the solar system, forming a complex cosmic environment. The position of the Earth and the cosmic environment have a profound impact on its own movement and change.

The outer part of the Earth is the atmosphere that surrounds the Earth's surface.

The Earth and seven other planets orbit the Sun to form the Solar System.

From near to far from the Sun is Mercury.

Venus, Earth, Mars, Jupiter.

Saturn, Uranus, Neptune.

There are also many galaxies of the same size as the solar system outside the solar system, called extragalactic galaxies, and the Milky Way and extragalactic galaxies make up the total galaxy. The total range of galaxies is between 15 billion and 20 billion light-years that we can observe today, and the space of these celestial bodies is not completely vacuum, and there are many electromagnetic waves. So it's just a high vacuum.

Beyond the earth is the universe, and there are countless celestial bodies in the universe, and beyond the universe we cannot understand at present, some people think that it is a larger unknown world or a parallel world to us, and some people think that it is other universes.

How to understand. Stephen Hawking said, "The universe is finite and unbounded".

These words seem to flicker in the blink of an eye, how do we make sense of them? The universe is not infinite, it has been proven by modern physics that we have understood that the universe we live in actually started from the singularity of the universe, and then the universe had time. Space and time are inseparable; There is no point in knowing about their existence alone.

Then the universe expanded, and so far, we see that the universe is still expanding, with no tendency to stop and contract. Therefore, our universe is not infinite and not homogeneous. In fact, he is expanding and expanding.

He begins not as a matter of meaning, but as a singularity of space and time, where everything we understand in this world is meaningless.

About Infinity. The universe exists in the same way, in a three-dimensional space, the universe is infinite, and when you think of distant cosmic boundaries, it's really just going around in circles in curved space-time, and you can never find the boundaries of the universe. It's as if you're following the surface of the earth, and you can't find the edge of the earth.

However, when we jump out of the reality of three-dimensional space, the dimensions and stand in the 4 higher positions, we can easily find that the universe is finite, just as we look at the earth from space, just as we look at everything at a glance.

It is not difficult to see that if we find the boundary on the surface of the earth, it is equivalent to climbing a tree to find fish, but as soon as we understand this, the ship leaves the surface of the earth, using all the clarifications, say, at that time we left two-dimensional, three-dimensional, so that it will be easier to discover the secrets of the earth. In the same way, when we find another way to say goodbye to the three-dimensional space, to a higher direction, we immediately see the truth of the universe from Him, in this universe. This method may be the wormhole described by Stephen Hawking, or it may be the answer to the natural black holes in the universe, some of which have singularities.

It is conceivable that there are countless other universes just beyond our universe, but they are not our image, in the form of three-dimensional space, but a multi-dimensional, beyond our visual impression.

To sum up, I think that outside of the universe, there is still the universe.

There are many things we keep exploring but we don't know, like the earth or the universe. Do you know what's beyond Earth? Let's find out.

Introduction to the universe

The statement of the universe is also different, the universe is very large and has no boundaries, unlike our earth, which is finite and unbounded. It's like there are people outside the sky. There may be a greater unknown world beyond the universe, which we cannot know at the moment.

A long time ago, people thought that the earth was the center of the universe, and then the sun was the center of this, but now it is actually believed that the universe has no center. Upon further discovery, the Milky Way is actually made up of countless galaxies and does not change over time.

It is also possible that there is no space in the universe, and such universes are parallel. Then it means that there may be other universes, and in other universes there may be something exactly like us, and there may be another earth. But there is no intersection between such spaces.

In general, the universe is an infinite space with a lot of matter and galaxies, and we are ignorant of such space, and if we want to explore the universe, we need to work hard, do you understand?

Earth is one of the eight planets in the solar system, the third in order of near and far from the sun, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, 100 million kilometers away from the sun.

What's inside the earth

The Earth's interior has a core, mantle, and crust structure. Specifically, it can be divided into: lithosphere, asthenosphere, mantle sphere, outer nuclear liquid sphere, and solid core sphere.

1. Lithosphere

For the Earth's lithosphere, it is not directly observable except for the surface morphology. It consists mainly of the Earth's crust and the top of the upper mantle in the mantle sphere, passing down from the solid Earth's surface through the first discontinuity (Moho surface) shown by the **wave at nearly 33 km, and extending to the asthenosphere.

2. Soft flow ring

In the upper mantle, about 100 kilometers below the Earth's surface, there is a distinct low-velocity layer of ** waves, which was first proposed by Gutenberg in 1926, called the asthenosphere, which is located in the upper part of the upper mantle, that is, the B layer.

3. Mantle circle

**In addition to a significant discontinuity at the sensitive foci about 33 km below the ground (called the Movwangho surface), the wave belongs to the mantle sphere at the interface below the asthenosphere to a depth of about 2,900 km in the Earth's interior.

4. Outer nuclear liquid sphere

Beneath the mantle sphere is the so-called outer hydrosphere, which lies at a depth of about 2,900-5,120 km below the surface. The entire outer nuclear liquid sphere may basically be composed of liquids with very low kinetic viscosity, of which the depth of 2900 to 4980 km is called the E layer, which is composed entirely of liquid bridges.

5. A solid core ring

The closest of the Earth's eight spheres to the center of the Earth is the so-called solid inner core, which is located at the center of the earth at 5120-6371 kilometers, also known as the G layer. According to the detection and study of the ** wave velocity, it is proved that the G layer is a solid structure.
