Why can’t solar energy light up the universe? Scientists uncover the secret of the darkness of the universe

With the development of science and technology, people are more and more curious about space. They constantly launch various kinds of detectors, detect whether there are signals of alien civilization in the universe through electric telescopes, and search for planets similar to the earth through astronomical telescopes.


Although human beings explore space more and more frequently, our understanding of the universe is only half understood, and our understanding of the creatures in the universe is just the tip of the iceberg. There are still many secrets of the universe waiting for us to uncover.

There are many galaxies in the universe, and the photos taken by the detector are also very dreamy. But there is a question that has been puzzling us all the time. Why is the universe still dark under the illumination of so many stars?


As we all know, the sun is the only celestial body in the solar system that can emit light. The earth is a planet in the solar system, and also the only known planet in the solar system that has life. It is precisely because of the existence of the sun, to give the earth light and warmth, so that the earth can give birth to life.


According to the measurement of scientists, the distance between the earth and the sun is very far, reaching 150 million kilometers. However, it’s just such a long distance that brings the earth just the right temperature.

Such a distance seems to have been set for a long time, not very far, not very close. Because of the existence of the sun, we can see the sun every day, enjoy the sun, and also enjoy the moonlight rendered by the sun.


So why can the sun illuminate the earth and the moon, which is very close to the earth, but not the space? This problem needs to be viewed from a scientific point of view. The reason why people can see light is because there are many particles in the air.


Every time the sun shines on these small particles, light is reflected, so the earth is illuminated. And how does the sun illuminate the moon? Because the moon itself has a strong light transmission, so it can be easily lit by the sun.

According to scientists, the main reason why the sun can light up the earth is that there is a large amount of dark matter in the universe. The function of these dark matter is to absorb the light emitted by all stars in the universe, and it has its own unique ability to make the universe dark.


In short, dark matter is equivalent to a carrier, constantly absorbing the light from the bright sun, and spreading more intense dark light into the universe.


As we all know, there are many stars in the universe. Although all stars glow and heat, they still have no way to light up the universe.

That’s because there’s something that we can’t see, which scientists call dark matter. It is understood that this kind of matter is smaller than electrons and photons, and can pass through the gravitational magnetic field. There are numerous in the universe, so it can be said that they are everywhere. This is the biggest reason why the universe is so dark.


In addition, this dark matter cannot be observed directly. So how did humans discover dark matter? The problem is very simple. Although dark matter can not be observed directly, it can interfere with gravitational waves emitted by stars, and human beings can find the existence of dark matter by observing the waves of gravitational waves.


In fact, I think that although the sun is very big, it is also very small compared with the universe, so it is very difficult to illuminate the universe with the power of the sun alone. What do you think of this? Welcome to leave a message in the comment area!
