Many speakers present, especially the speakers of the fifth-level civilization, each have a detailed list of data about the universe.
Including a variety of galaxy groups, superclusters, and so on and so on.
But at this moment, I heard that Noah would personally introduce information about the Virgo galaxy cluster.
These talkers and commanders still showed expressions of listening carefully and humbly.
Li Chen himself stared at Noah with burning eyes, waiting for him to speak.
[First let's take a look, this is the location of the Virgo galaxy cluster. 】
[Everyone can try to find the position of our local galaxy group on this, I have given an approximate range...]
As Noah said, the three-dimensional star field map on the huge holographic light curtain in front of everyone began to flicker.
Within a palm-sized area, countless mottled light clusters appeared.
Seeing that Noah seemed to be trying to test himself on purpose, the talkers present and the commanders all started to raise their hands.
Everyone is eager to try.
Li Chen, on the other hand, watched the performance of these talkers with leisure.
His gaze has locked on to the palm-sized area highlighted on the map of the star field.
Intuition told Li Chen that the area on this palm-sized star field map is definitely not the local galaxy group!
Because it is clear at a glance.
Within that palm-sized area, there are densely packed galaxies that resemble the Milky Way, or present a bar-shaped spiral, or a disc-shaped, or scattered galaxies in irregular shapes.
Their characteristic is obvious, that is, there will always be an area where the brightness is very concentrated.
That is their gravitational source, which is the most concentrated area of the star system.
Belonging is the core part of a galaxy.
In the entire galaxy, all celestial bodies will revolve around the core area of this gravitational source.
The specific revolution time is of course also different.
It depends on the position of the celestial bodies and the strength of the gravitational force they receive, and so on.
The reason why Li Chen determined that the palm-sized area is not the local galaxy group is because the local galaxy group can be called a large galaxy.
And there are only a few galaxies that can emit that level of brightness, strictly speaking.
Except for the largest Andromeda Galaxy, the Milky Way, the Triangulum Galaxy, and the Large Magellanic Cloud, etc., the rest of the galaxies are small galaxies.
Placed in front of Li Chen, their diameters of hundreds or thousands of light-years may be very large.
But after being reduced in scale, they are almost as non-existent as the original earth under the scale of the universe.
You can't even locate them on a map!
While Li Chen was observing and thinking, Noah spoke.
[Mr. Titan Wang, please answer it! Have you found the location of the Local Group of Galaxies on the map? 】
Noah looked at King Titan and smiled.
When Li Chen heard the words, he also looked at King Titan.
This is the speaker from the pinnacle of the fourth-level civilization, which is close to the fifth-level civilization, and was born in the most prosperous and affluent area of the Milky Way.
His knowledge is much higher than that of other low-level civilized speakers.
Whether your own judgment is correct or not, you can get the answer immediately.
Hearing Noah's roll call, he asked himself to answer the question.
The Titan King, who was already eager to try, immediately stood up excitedly.
"Master! Mr. Noah!"
King Titan answered Noah's question confidently.
After hearing his words, people who were talking about other things looked at Noah one after another.
Li Chen also showed a curious expression.
Noah didn't speak, and walked forward with a smile. With a thought, he began to enter the relevant coordinates on the star field map.
According to the starry sky coordinates mentioned by King Titan just now, after inputting the corresponding numbers.
Sure enough, the map of the star field has changed.
The interface changes to a panoramic view of the Local Group of galaxies.
The Milky Way, which has been developed to only sporadic star systems, and the Andromeda Galaxy, the largest galaxy in the local galaxy group, and the Triangulum Galaxy and so on.
All of these galaxies appeared in front of everyone.
Everyone involved is very familiar with them, without any verification, they have already recognized the location of the local galaxy group with just a glance.
Seeing that even the Titan King can answer accurate questions.
The rest of the high-level talkers are full of confidence in their hearts.
Their eyes became even hotter, more eager to try.
Everyone wants to express themselves well and show their knowledge and ability in front of their masters.
[The answer is correct, your answer is very standard and accurate, Mr. Titan Wang. 】
[It seems that you still have a basic understanding of the universe. 】
Noah smiled slightly at King Titan, giving him affirmation and praise.
These words made the already high-spirited Titan King even more proud.
At this time, Noah did not respond to the expectant eyes of the rest of the people, but smiled slightly.
And then continue to explain.
[As you all have seen just now, I have divided a small area on the map of the star field, where Mr. Titan Wang accurately found the location of the local galaxy group. 】
[But I am not going to play a game of guessing coordinates with you, but I want to tell you that in that small area just now, besides the local group of galaxies, there are about a hundred other groups of galaxies. 】
[Note that I'm talking about groups of galaxies, not single galaxies. 】
Noah's emphasis made the faces of many talkers slightly shiver, but that's all.
These data information are already known to them.
On the contrary, at this moment, Li Chen's heart moved after hearing Noah's words.
It seems that my judgment was right again.
The members of the Virgo Cluster are not single galaxies, but groups of galaxies.
Galaxy groups and galaxies, although there is a difference in one word, represent two different meanings.
A galaxy often refers to a single system of celestial bodies.
The group of galaxies is a composite system of celestial bodies.
Take the Local Group of galaxies for example, which contains dozens of galaxies.
In other words, the data observed by the scientists of the original earth were wrong.
If this is the case, then the area of the Virgo galaxy cluster is definitely not the area Li Chen recognizes.
Of course, there are far more than 2,500 galaxies in it!
Realizing this, Li Chen's expression became relaxed.
He continued to watch Noah listen carefully to the other party's introduction.
[The total area of the Virgo galaxy cluster is the part I am underlining now, because the division of the galaxy group inside it is relatively average, so you can try to calculate it. 】
[Look at how many areas it has. 】
