Are human beings lonely beings in the universe?

Human beings are lonely in the universe, and the distance between various civilizations is too far to cross, so human beings are lonely most of the time.

If humanity is the last generation of civilization in the universe, after the demise of mankind, the universe will become dead. In the universe, every galaxy is composed of hundreds of billions of planets, and as far as this is true, mankind has not found any other civilization on other planets.

What if humanity was the last civilization in the universe? Based on our current knowledge of physics, chemistry, biology, and cosmology, the galaxy should have been filled with interstellar civilizations that colonized the galaxy a long time ago. However, in reality, we have found no evidence of any alien visits to Earth.

Not even a radio signal from an extraterrestrial civilization has been received, and there is a theory that is the Great Filter Theory.

This theory holds that extraterrestrial civilizations are all filtered out by the nine conditions under which life is formed, and the more advanced a civilization is, the greater the risk of extinction for them. The evolution of life has been long and difficult, from single-celled animals to the current industrial civilization. It took 1 billion years for the earth to take the earth, but humanity is currently only at the level of civilization.

As human beings continue to explore space, this index will increase, and from the perspective of lung meters, advanced civilizations should be universal in the universe.

If the multiverse is also taken into account, then this order of magnitude is even more. If human beings are the last generation of civilization in the universe, then after the demise of human beings, the universe will become a dead machine, and there will be no signs of civilization activities anywhere. With the passage of time, the marks left by human beings in the universe will slowly disappear, and all the physical quantities created by human beings will become meaningless.

Without wisdom, the length of civilization and time, the physical quantities created by these people will become meaningless.

But without human beings, the universe would still run as usual, and the sun, moon and stars would still move according to their original trajectory. As if human beings never existed, it is indeed a pity for human beings that they did not understand the nature of the universe and disappeared in the long river of history.

There is no way to think of this thing, because the current development of human beings is very good, and even the last generation of civilization will develop for a longer time.

Incredible things will happen, and if humanity is really the last generation of civilization, then something very incredible will happen, and humanity may explore a lot of unknown puzzles and have a deeper understanding of the universe.

It is likely to lead to the destruction of the planet, as well as the extinction of life and humanity on the planet.

Humanity may eventually come to an end, everything will be overturned, and the earth will return to the Ice Age.

We all know that stars are an important part of the birth of intelligent life, just like our earth loses the sun, life ceases to exist.

So, with the number of stars in our universe so large that it is impossible to observe, are we humans still alone?

In fact, regardless of whether there is intelligent life on other planets in the universe, we humans are alone.

How so?

Our nearest star is only 4 light-years away, but it's still far beyond our capabilities (we can't even communicate with it).

So: how can we connect with other alien species that may or may not exist?

Do a thought experiment and imagine an ant in the United States. Do you think it knows that there are other ants outside the United States? Do you think it knows about the existence of other countries?

In the same way, we look up at the stars on Earth. We are the ants of our country. Of course, the only difference is that we can see much more ants, but just like ants, we can't reach these distant places.

Because the universe is so big and so far away, any argument for the existence of extraterrestrial life is superfluous. Our radio messages have traveled about 200 light-years in all directions, which is equivalent to the diameter of the Milky Way. We haven't even touched the surface of the Milky Way.

The same can be true of aliens. If they were there, they wouldn't have known about our existence for the same reason.

Can you imagine any communication between the planet 300 light-years away and us? Let's simulate a mountain of pants.

Hello, Blue Planet, I'm X from Planet XX.

300 years later.

Me: Hi X, I'm o from Earth (Blue Planet).

300 years later.

Hi o, x died 300 years ago. I'm X's grandson, how are you?

300 years later.

Hello, grandson x, the situation is not very good, o died 300 years ago.

If this cycle continues, it will be difficult for us to communicate with life forms on another planet.

By the way. The earth was formed 4.6 billion years ago, and aerobic photosynthesis occurred for nearly 2 billion years, which means that the emergence of life is also a very long-term process, and the earth is also reasonable as an early group of life planets.

Of course, we can only say that we humans are lonely at present, and definitely not in the future.

Human evolution, the process by which humans developed on Earth from the now-extinct primates. From a zoological point of view, we humans are Homo sapiens, a cultural species that lives upright on the ground and most likely first evolved in Africa about 315,000 years ago. We are now the only living member of what many zoologists call the hominini, the human tribe, but there is plenty of fossil evidence that over millions of years, other humans such as apes, australopithecus, and other species humans, and that our species is also at least another member of our genus H

Neanderthalensis lived at the same time for some time.

In addition, we and our predecessors have been sharing the Earth with other ape-like primates, from modern gorillas to the long-extinct Australopithecus. We have a connection to extinct hominins, and we have a connection to living and extinct apes, which is accepted by anthropologists and biologists around the world.

However, the exact nature of our evolutionary relationships has been the subject of debate and investigation ever since the great British naturalist Charles Darwin published his magnum opus, On the Origin of Species (1859) and The Origin of Man (1871). Darwin never claimed that "man is descended from apes", as some of his Victorian contemporaries insisted, and modern scientists would dismiss this claim as a useless simplification as much as they would refute any popular notion that some extinct species was the "missing link" between man and ape.

However, there is a theorized common ancestor that existed millions of years ago. This ancestral species does not constitute a "missing link" along a lineage, but rather a node that differentiates into different lineages. This ancient primate has not yet been identified and may never be determined, as fossil relationships are unclear even in newer human lineages.

In fact, a human "family tree" may be more appropriately described as a "family shrub", in which it is impossible to link a complete chronological series of species, leading to the expert agreement of Homo sapiens.

The formation of the universe was caused by a large ** that occurred about 13.7 billion years ago. After a period of evolution from hot to cold, the universe was born in the ** of chaotic celestial bodies.

Human beings are primitive single-celled organisms that evolved over a long period of time.

The formation of the universe is mysterious, and we have not yet explored how the universe came into being, and we don't know what the situation is.
