How big is the universe and is there another Earth 5

At present, the maximum size of our universe is about 1500 160 billion light years, and it continues to expand.

For example, in the universe in which we live in four dimensions (three-dimensional space), scientists estimate that there are about 100 billion galaxies, each of which is calculated by multiplying (1000 200 billion stars) by 5 as the number of rocky planets. Well, there is still a possibility that there will be a planet like the Earth. It's just that advanced life forms like humans are too demanding on the environment, and it's still difficult to find advanced life forms like humans.

In addition, according to the theory of parallel universes, there should be another Earth. Ultimately, however, this needs to be empirically demonstrated.

However, mankind's exploration of the universe is endless, especially in recent years, the development of microelectronic technology has made great progress in the technology of exploring the universe.

I believe that one day, whether it is the immigrants who go to the earth or the new humans who have discovered, there will be an environment and human habitation like the earth on other planets.

The universe is known to be 14.7 billion light-years in size and is still expanding.

There are more than 1,000 known extraterrestrial planets in one class, and there are hundreds of billions of ** planets in the universe, so there must be one like the Earth, right?

The universe is as big as your heart, and you can have as many earths as you want.

According to the heterogeneous space, there are n spaces.

The universe is big.

Diameter of the Earth. It is the fourth of the eight planets.

The observable diameter of the universe is 93 billion light-years (one light-year is about 1 billion km), and the Earth and the universe are not on the same order of magnitude.

The universe is big, and the earth is only a small part of the universe.

Earth is the third and fifth largest planet from the Sun:

Age of the Earth: 4.6 billion years.

The mass of the Earth is to the power of ) kilograms;

The volume of the Earth is to the power of cubic kilometers;

The surface area of the Earth is to the power of square kilometers.

The total area of the Earth is 510,000,000 square kilometers.

The universe, on the other hand, is infinite, because the universe is the sum of all physical space and time, and time is infinite.

The word "universe" probably originated from the famous ancient philosopher Mozi (about 468-376 BC). He used "universe" to refer to the east, west, south, and north, and the space in all directions, and "Zhou" to refer to the time of the past and the present. Past, present, or future; Is it a recognized, or an unrecognized......In short, everything is everything.

From a philosophical point of view. It is believed that the universe has no beginning and no end, and that it is boundless. However, we are not going to go deep into this esoteric concept, and we will leave it to philosophers to study.

We might as well zoom out a little and talk about the universe that can be understood and observed using the science and technology available to us, which people call "our universe" or "total galaxy".

Is the Earth bigger, or is the universe bigger?

Of course, the universe is big, and the earth is really insignificant compared to the universe.

The so-called universe, the upper and lower four directions are the universe, and the ancient and modern are the universe, in order to metaphor the heaven and the earth. Universe is the concept of space, and Universe is the concept of time.

Of course, the universe is large, and the entire universe includes many planets, including the earth, and the earth is only a part of the universe.

It must be the universe big. The Earth is very small to the universe.

The diameter of the Earth is 12,742 kilometers, and the universe is known to have a diameter of 156 billion light years. Not an order of magnitude at all. The universe is much larger than the Earth.

When the ancient Chinese created the term "universe", they did not know that the earth was the earth, and described that the heaven and the earth were very large [the upper and lower four directions were called the universe from ancient times to the present], that is, the universe includes heaven and earth, and now astronomical discoveries that the sky is very high and very large, far larger than the earth, and this huge [heaven] is called "universe" by scientists. There is no doubt that the universe is larger than the earth, and the earth is an insignificant dust in the universe.

The Earth is smaller than the universe.

宇宙 yǔzhòu: The infinite space that includes the earth and all other celestial bodies.

Infinite space that includes all celestial bodies.

"宇" refers to infinite space, and "宇" refers to infinite time. The totality of all matter and its forms of existence. Philosophically, it is also called "the world".

Earth dìqiú: This planet inhabited by humans, one of the nine planets of the solar system, has an average distance of 149.6 million kilometers from the sun, ranking third among planets, and its equatorial radius is kilometers, ranking fifth among planets in terms of size.
