We often say that we can see the moon through the clouds. When the moon is blocked by clouds, we can only see light or nothing at all. There is a similar situation in space, often covered by foggy matter. These hazy clouds of gas have puzzled scientists f

Currently, a particle physics theory believes that in fact there are nine-dimensional spaces in the universe, and black holes may be the key to other universes, which means that black holes are the gates to other universes. So, through a black hole, it is

Black holes have always been a mysterious existence, and no one has ever seen them. They only exist in science fiction films and Hawking's papers. The picture of the black hole we see is a sky area that can devour all planets, whose density and volume can

In the vast universe, all kinds of magical things are possible. Scientists have also been exploring the mysteries. The phenomenon of black holes swallowing stars that I told you today is also a spectacle in the universe. What will happen when black holes

Everyone has heard of black holes, because of the huge gravitational force, any matter that approaches a black hole will be swallowed up, and even light cannot escape. Previously, scientists have observed the whole process of the black hole eating the sun

What is a Kerr black hole? At first, like many netizens, I didn’t know it. Until a few days ago, I accidentally saw a report about a Kerr black hole a few years ago. The report said that a physicist from the University of Washington in the United States

In countless sci-fi films, the black hole is a mysterious existence. The black hole is actually the entrance to the universe and enters another dimension. A primary black hole is a hypothetical black hole that was created during the Big Bang. Unlike other

The mysterious existence of black holes has attracted countless astronomers. It is naturally impossible to reach outer space, so astronomers are looking for alternatives to various black holes. Man-made black holes are made through particle accelerators,

In the vast universe, there are always different mysteries, which attracts countless scientists to explore this unknown world. Today, I will tell you about the cosmic speed. According to scientists, the fourth cosmic speed refers to the The minimum initia

We all live in the universe. How old is the universe? We all know that the universe was born in the Big Bang 14 billion years ago, and then everything and galaxies came into existence. Recently, space probes have sent back maps of the cosmic microwave bac

There is a theory of cosmic speed for some spacecraft and satellites launched, and the current theory has reached the sixth cosmic speed, which is faster than the speed of light. At the beginning, the first cosmic speed refers to the minimum launch speed

Scientists have been doing some research on the cosmic speed in the world. Today, the editor will tell you what the third cosmic speed is, and how about the sixth cosmic speed? I will give you a brief analysis of this kind of cosmic speed. Later in the ar

We know that the cosmic speed refers to the speed achieved by objects relying on gravity. The first cosmic speed is required to revolve around the earth, the second cosmic speed is needed to break away from the earth's gravity, and the third cosmic speed

The vast universe, the universe is very big, and the Milky Way is just a series in the whole universe, a galaxy where the sun and the earth are located, so what is the center of the whole galaxy? After years of research, scientists have also come to the c

We know that the universe is very vast, and with the current ability of human beings, it is still impossible to explore this complete universe. But although the universe is huge, it is impossible for it to be infinite. Then I can’t help but have a questi

The universe is 13.7 billion years old, and it was a baby universe before the Big Bang formed the universe we see today. Just like the appearance of human beings when they were just born, and this baby universe is not as big as the current universe. It be

What does the universe we live in look like? Recently, the European Space Agency released a panorama of the universe. What we usually see is a picture of a certain planet in the universe, and this panorama of the universe is an ordinary The most precious

In Greek mythology there is a character called Theia, but this is not what we are going to talk about this time. It is a planet called Theia. We know that there are eight planets in the solar system, but there was a planet before, not Pluto, but this Thei

For a long time, although we have known the existence of black holes, and there are various pictures of black holes on the Internet, in fact, these pictures of black holes are all imagined based on theory. No one knows what a real black hole looks like. I

Vy Canis Major, once the largest planet in the universe, had a radius about 2,000 times the radius of the sun, but it was found that it has already reached the end of life. A large amount of mass is lost every year, and the mass is only 40 times that of t
