I'm an almighty star

Chapter 1138 How big is the universe?
"Finding a needle in a haystack is finding a needle in the universe."

Like the Chinese people, there is also the US Space Agency who pays attention to Huaguo Sky Eye.

Yes.

Even, they pay more attention to it than some Chinese.

However, they did not expect that the Huaguo Tianyan Research Center would foolishly conduct a live broadcast.

Hearing this news at that time, all the people in the US space agency were almost happy.

"no Zuo no Die."

"Sure enough, it is a country with no background. Do they think that capturing pulsars is just a look with a binoculars?"

"It's a joke. Even if their celestial eyes seem to have better parameters than ours, they won't be able to find out within a few dozen days. If they're unlucky, there won't be any traces for a year or even two years."

This is telling the truth.

Regardless of the fact that the astronomy community has discovered more than 2000 pulsars.

But these pulsars were discovered by tens of millions of researchers from dozens of countries in the past few decades.

On average, in these dozens of countries, it is already great luck to discover one pulsar every year.

It's ridiculous, these guys even come to a live broadcast.

"It's okay, it's okay, I still had some celestial eyes that were worried about them before, but looking at it now, it's just like that."

"Well, this further proves our guess. It is impossible for Tianyan to have such a function. Even if it has such a function, I believe they will not use it very much."

"Capturing a pulsar is not just a matter of looking through the telescope. Among them, a large number of stars have to be selected, compared, and finally obtained. Even if it is actually found to be a pulsar sometimes, but When it is confirmed, everything is unknown."

"The Chinese people are still too anxious. They are eager to prove it to their people. But with their foundation, they can't do it at all."

"Yes, I believe this live broadcast will only be broadcast for a while for everyone to watch. As for whether or not the pulsar can be captured, it is not the task of this live broadcast."

A group of researchers at NASA became more relaxed.

They squinted their eyes, watching the live broadcast, and talking funny things at the same time.

"Look for a needle in a haystack, I'll go, can I find it here?"

"I don't know, I didn't expect to find a pulsar to be so difficult."

"It must be difficult, otherwise, why would the United States still use this to pretend. Some experts say that it will take at least a few months from the beginning to the real discovery of a pulsar. If you are not lucky, it may even take a few years." .”

"Damn it, it's been so long, so what's the purpose of this live broadcast. Don't tell me, their so-called star hunting is just to show us during the live broadcast, and they can't really hunt for stars."

"This...I don't know either."

Many people who were watching the live broadcast felt a little bit in their hearts, feeling bad.

If this is the case, what's the point of today's live broadcast?

At most, let us open our eyes and know how these astronomers work.

However, what they are looking at is not how astronomers work, nor how they hunt for stars.

What they want to see is whether you have hunted stars.

If the star cannot be hunted, even this 500-meter-caliber sky eye is nothing more than a huge individual at best.

"Hey, why did I see an acquaintance."

"Professor Li, who did you see?"

"Didn't you see it? Look, is that Mo Bai?"

"Mo Bai?"

Pointing to the camera, the man standing in front of the big screen, the host watched carefully.

At this time, the lens is also pulled from the original distant view to the close view.

If it was not clear before, but now, the man's face has completely appeared in the camera.

"Mo Bai."

"My God, it's really Mobai."

The host freaked out.

"I made a move, Baishen appeared."

"Why are there white gods everywhere?"

"Don't tell me, Baishen, why don't you study astronomy instead?"

I said something just now, and some people who were gradually losing confidence were trying to get out of here.No, when Mo Bai appeared, no one wanted to leave.

"Hi everyone, I'm Mo Bai."

It seems that this live broadcast specially arranged for Mo Bai to interact with everyone.Facing the camera, Mo Bai said: "Okay, everyone, stop guessing. I know everyone has doubts about why I am here. Let me tell you the truth, I have recently become interested in astronomy. Well, if possible , you can call me an amateur astronomer."

Mo Bai introduced himself a new identity.

But fortunately, this time Mo Bai was more modest, adding an amateur in front of the astronomer.

"Hehe, Baishen has become humble."

"It's rare, it's rare, but this amateur astronomer feels like laughing."

"I want to laugh too, I don't know what this guy wants to do."

When Mo Bai appeared, everyone forgot all their thoughts about capturing pulsars, and kept staring at Mo Bai.

"Well, as an amateur astronomer, I think it is necessary to share some astronomical knowledge with you. What about science, I won't talk about advanced ones, anyway, you won't understand it anyway. Just say something simple. , how big is our universe."

Mo Bai said, at this moment, a globe appeared on the big screen.

Facing the screen, Mo Bai said: "Maybe everyone has no idea about this question. How big is the universe? Everyone will definitely think it is very big. However, I don't know how big it is. As for me, how big is the universe?" How big, I will tell you that the diameter of the universe is about 1600 billion light-years. However, you still don’t have a specific feeling about how big 1600 billion light-years are. Then, let’s use the comparison method to let everyone really feel the universe the vastness of

Mo Bai is an excellent speaker.

This is due to the reason why Mo Bai likes to pretend.

Mo Bai believes that an excellent pretender must first have good eloquence.

Although he is an amateur astronomer, what Mo Bai wants to show must not let them see that he is half amateur.

"Let's take a look at our earth. We know that our earth is already very big. But, compared with the nine planets in the solar system? Saturn is 830 times that of Earth, and Jupiter is 1300 times that of Earth."

"Compared in this way, do you feel that the earth is very small? Yes, the earth is indeed small. But how small is it? Let's compare it with another one. When we talked about the sun just now, let's compare it with the sun. The sun is 130 times the size of the earth. Thousands of times... Now we will draw the sun, Jupiter, Saturn, Neptune, the earth... these into a straight line, let's take a look. No, this is the earth. The earth has become a small dot in front of the sun."

This comparison is very clear and vivid.

The eyes of all the friends who were watching the live broadcast were bright, and they were watching with gusto.

"Of course, this is not over yet. Is there only the sun in the whole universe? No, no. We know that our galaxy is the Milky Way. The solar system is a star system in the Milky Way. So, how big is the sun in the Milky Way? "

"Like the Earth, the Sun becomes a tiny point in front of the Milky Way."

Turning over a few PPT pictures, many people feel that they are eye-opening.

Of course, the science spectrum is not over yet.

After introducing the Milky Way, Mo Bai began to introduce the local group of galaxies: "Let's take a look at the local group of galaxies. The local group of galaxies is the galaxy group we are in. This galaxy group consists of more than 50 galaxies, including the Milky Way. Our Milky Way is in the local group of galaxies, it is very embarrassing, it seems very small, and it does not rank at all."

"However, this is not bad. After all, we can still see our Milky Way in the local group of galaxies. Then, take a larger galaxy group for comparison. For example, this Virgo supergroup of galaxies, where we are Compared with it, the group of galaxies also becomes a point. As for the Milky Way, it is no longer visible on this map."

The galaxy groups on the PPT continue to appear, and each galaxy group refreshes people's three views.

Until the end, Mo Bai released the last picture.

"This picture is a map of the universe drawn by a scientist. Have you seen it? There are densely packed stars here. However, it is said to be stars, but it is not a star. Every point here is a huge super Galaxy clusters..."

When Ke Pu arrived here, everyone in the live broadcast room was completely dumbfounded.However, Mo Bai did not finish his introduction: "Oh, I'm sorry, I made a slip of the tongue. This map of the universe is not the real universe, it is just the universe we can see. So, how big is the real universe, what we see Compared with the real universe, the universe is just like the star points in this picture."
