So far, the farthest place that humans have gone is the Melanie star that Xincheng went to with Lomus 3. The distance from the sun is 20 billion kilometers. It is also the first time humans have set foot in the Kuiper Belt. If not for Lomus 3,
All the crew members of the Musi-3 except Xincheng died, so this is definitely an astronomical event worthy of celebration by all mankind.
However, this historic excursion of mankind is still 180 billion kilometers away from the Oort cloud, the spherical cloud surrounding the solar system. In other words, mankind has only walked one percent of the distance.
The Oort Cloud is even larger in size, with a radius of one light-year, or more than 940 billion kilometers.
The fastest human aircraft currently is the Victory Condor using the New Max power system. Its top speed reaches five-twelfths of the speed of light. This means that the Victory Condor needs to fly at the fastest speed for eight years starting from the earth.
It will take a long time to fly out of the Oort cloud.
This can only be achieved if there is unlimited energy, no loss of parts, and no problems with the airframe. In fact, the Victory Condor’s new Max engine can currently operate continuously for eight hours, let alone eight years.
arrive.
After breaking out of the Oort cloud, we entered the 'local interstellar cloud', which is about thirty light-years in size. In other words, the Victory Condor flew at the fastest speed from 1777 until today.'
'Local Interstellar Cloud', and then entered the 'Local Galaxy Bubble'.
The 'Local Galaxy Bubble' spans a distance of 300 light-years. The Victory Eagle had to start from Alexander the Great's Eastern Expedition, that is, 400 BC, and fly at the fastest speed until today before it can break out of the 'Local Galaxy Bubble'.
', entering the Gould Belt with a diameter of more than 3,000 light years. To cross the Gould Belt, the Victory Condor needs to fly continuously for 24,000 years.
The Gould belt is only a small part of the Orion spiral arm, because the Orion spiral arm is at least 26,000 light-years long, and it would take the Victory Condor to fly continuously for at least 208,000 years;
But the Orion Arm is just a small spiral arm in the Milky Way. The Milky Way is 200,000 light-years in diameter, and it would take the Victory Eagle 1.6 million years to fly from one end of the Milky Way to the other.
The Local Galaxy Group, where the Milky Way is located, covers an area of 10 million light-years. The Victory Condor would have to fly since the age of dinosaurs and last for 80 million years before it can fly across the Local Galaxy Group.
The Virgo galaxy cluster, which includes the local galaxy group, is even larger, with a diameter of more than 100 million light-years. To cross it, it would take the Victory Eagle to fly for 800 million years. At that time, life on Earth had only entered the multi-cellular stage.
The Laniakea Supercluster, which is composed of multiple galaxy clusters such as the Virgo Galaxy Cluster, the Hydra Galaxy Cluster, and the Centauri Galaxy Cluster, has a diameter of more than 500 million light-years.
What a huge number this is. Take the Milky Way as an example. There are more than 100,000 such galaxies in the Laniakea supercluster, and a Milky Way galaxy has hundreds of billions of stars. The entire Laniakea supercluster has hundreds of billions of stars.
The total number of stars in the Achaia Supercluster reaches terrifying billions.
This is not enough to exhaust the sand in the Ganges River, but to exhaust the E. coli in the Ganges River before we can count it.
Is the Koraniakea Supercluster the largest structure in the universe?
Of course not, because humans only discovered a few years ago a huge superstructure with a diameter of more than 10 billion light-years, a width of more than 7 billion light-years, and a thickness of one billion light-years - the Hercules-Corona Borealis Great Wall.
The number of galaxies in it is also countless, because the current data is not the final size of the Hercules-Corona Borealis Great Wall, but the limit of human observation.
It can be seen that the Laniakea supercluster where the Milky Way is located is naturally included in a huge superstructure similar to the Hercules-Corona Borealis Great Wall, but it is difficult to observe it if you are inside it. Even the Hercules
-Above the Great Wall of Corona Borealis, there is an even larger cosmic structure, but it has not yet been discovered by humans.
After all, human cosmology previously believed that the limit of the universe was 1.2 billion light-years, and before the discovery of the Hercules-Corona Borealis Great Wall, the Laniakea Supercluster was thought to be the largest.
The current range of the observable universe by humans is 46 billion light-years. The Great Wall of Hercules and Corona Borealis spanning 10 billion light-years has been discovered. With the advancement of science and technology, the range of the observed universe is even larger.
After a while, we will definitely discover more massive cosmic structures.
This is humankind's exploration of the universe. It is like a blind man touching an elephant. He can only know the part he touched and knows nothing about other places. He doesn't even know how to guess or think about it.
Just like the human body is composed of cells, cells are composed of molecules, and molecules are composed of atoms. There are neutrons in atoms, and neutrons are cut into protons. Protons contain electrons, and electrons contain quarks.
If the universe is a person, then the earth is equivalent to a small quark, maybe even worse than a quark. On such a planet, no matter how many intrigues, fights for power and even blood flow, it will become the ultimate planet.
The winner is only the overlord of quarks that are too small to be seen with the most advanced microscopes, let alone one of the countless quarks.
Compared with the vastness of the universe and the infinity of time and space, human beings are nothing and the earth is nothing but ant dust.
Chiba Cheng was staring at the stars in a daze. He was thinking of the infinite universe and the infinite time and space. Eight or nine billion people are crowded on this small planet. How many people spend their whole lives working day and night for a room.
No matter how hard you work, even if you look up at the stars, you can only sigh with emotion at the vastness of the universe, and then you can only helplessly continue to bow your head and act like a cow.
But now I have the ability to go to the vast universe, to see the human beings on the earth, to see the wonders that I will never observe in my lifetime, to see if the triple star of Nanmenmen is really unsolvable, to see the Milky Way.
The supernova remnants in the heart and the spectacle of supermassive black holes devouring stars, as well as...
This chapter is not over yet, please click on the next page to continue reading the exciting content! There are so many planets and so much time and space, why do they have to be squeezed into the small earth.
Just one earth has so much magnificence, and the universe is so vast, so how many unimaginable wonders should there be?
Listening to Chiba Makoto's talk about imagining the universe, Maya couldn't help but have imaginings. What came to her mind were the images and pictures about the universe she saw on TV and the Internet.
A small photo of a black hole can trigger a worldwide carnival, and all mankind celebrates progress. But if you have the opportunity to see the true appearance of a black hole and the dazzling accretion disk, even if it happens in the next second
Being swallowed by a black hole, many people will flock to it.
Especially those scientists who have devoted their lives to studying the universe. Their minds wander in the universe, but they can only use various telescopes on the earth to look at long-term exposure photos. By analyzing these starlights from the distant past,
Come and get to know this universe.
If you can see with your own eyes what these distant galaxies look like today, there are also celestial objects that only exist in theory or even imagination, such as the final destination of most stars in the universe, which are completely cooled white dwarfs - black dwarfs, which are considered to be the Big Bang.
The next generation of stars - dark matter stars, supergravity objects that are more extreme than black holes - boson stars, transitional objects between neutron stars and black holes - quark stars... and so on.
Any one of these alone can kill scientists who have devoted their lives to studying the universe.
No matter how rich human imagination is, it cannot compare to the magic of the universe.
It's just that humans don't have the ability to go to the depths of the universe in a short time. Professional astronauts are needed to even leave the solar system.
However, Chiba Makoto will not be constrained by the lack of technology. He can easily go to farther places, witness the magic of the universe with his own eyes, appreciate the wonders of the universe, and find out if there is an edge to the universe.
