"Looking for a needle in a haystack, this is a cosmic needle. ”

As much as the Chinese people, there is also the United States Space Agency.

Yes.

They are even more concerned than some of them.

However, they didn't expect that Huaguo Tianyan Research Center would stupidly hold a live broadcast.

Hearing the news at that time, the people from the United States Space Agency were almost happy.

"If you don't die, you won't die. ”

"Sure enough, it's a country with no background, do they think that catching pulsars is just to take a look at a pair of glasses?"

"Joke, even if their Tianyan looks better than ours, but in a few dozen days, they won't be able to find out. If you're unlucky, there's no trace for a year, or even two years. ”

This is telling the truth.

Don't look at the astronomical community, more than 2,000 pulsars have been discovered.

But these pulsars have been discovered by tens of thousands of researchers in dozens of countries over the past few decades.

On average, the discovery of a pulsar every year in these dozens of countries is already great luck.

It's ridiculous that these guys even came to do a live broadcast.

"It's okay, it's okay, I was still worried about their eyes before, but now I look at it, that's it. ”

"Well, this proves our guess even more, it is impossible for Tianyan to have such a performance. Even if they do, I'm sure they won't use it much. ”

"Catching pulsars is not just a matter of looking at glasses, but also a large number of stars that have to be selected and compared. Even if it is sometimes discovered that it is a pulsar, nothing is known until it is confirmed. ”

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

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

The researchers at the NASA became relaxed.

They watched the live broadcast with their eyes wide open, and they talked funny things.

"Looking for a needle in a haystack, I'll go, can I get it?"

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

"It must be difficult, otherwise, how could Mi Guo still pretend to be forced by this. Some experts say that it takes at least a few months from the beginning to the actual discovery of a pulsar, and if you are unlucky, it may even take several years. ”

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

"This ...... I don't know. ”

Many people who were watching the live broadcast sighed in their hearts and felt bad.

If that's the case, then what's the point of today's live broadcast?

At most, let's open our eyes to how these astronomers work.

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

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

If you don't hunt the star, even if this 500-meter-diameter Sky Eye is only a huge individual at best.

"Hey, how did I see an acquaintance. ”

"Professor Li, who did you see?"

"Didn't you see it, you see, is that Mo Bai. ”

"Mobai?"

Pointing to the camera, the man standing in front of the big screen, the host took a closer look.

At this time, the camera also pulls from the original long view to the close view.

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

"Mo Bai. ”

"Oh my God, it's so white. ”

The host is scared to pee.

"I went and the white god appeared. ”

"Why is there a white god everywhere. ”

"Don't tell me, Shirakami, you're going to study astronomy. ”

I just said something, and some people who are gradually losing faith are trying to flash people. No, as soon as Mo Bai appeared, everyone still had the intention of leaving.

"Hello 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, don't guess. I know everyone has a question about how I got here. I'll tell you the truth, I've been interested in astronomy lately. Well, if you can, you can call me an amateur astronomer. ”

Mo Bai introduced himself to a new identity.

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

"Hehe, the white god is humble. ”

"It's rare, it's rare, but how does this amateur astronomer feel like laughing. ”

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

Mo Bai appeared, and everyone forgot all about catching pulsars, and kept staring at Mo Bai.

"Well, as an amateur astronomer, I think it's necessary to learn a little bit about astronomy. What is the spectrum, I won't say anything profound, anyway, you won't understand it. Let's just put it simply, how big our universe is. ”

Mo Bai said while at this time, an earth appeared on the big screen.

Facing the screen, Mo Bai said: "Maybe everyone has no idea about this issue, how big the universe is, everyone will definitely think that it is very big." However, I don't know how big it is. As for asking me how big the universe is, I'll tell you that the approximate diameter of the universe is 160 billion light years. However, there is still no specific feeling of how big 160 billion light years is. Then, let's use the comparison method to let everyone really feel the vastness of the universe. ”

Mo Bai is a very good speaker.

This is due to Mo Bai's penchant for pretending.

Mo Bai believes that an excellent master of pretending must first have good eloquence.

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

"Let's take a look at our planet, and we know that our planet is already big, big. But what about the nine planets of the solar system? Saturn is 830 times the size of Earth, and Jupiter is 1,300 times that of Earth. ”

"Doesn't it feel like the earth is very small? Yes, the Earth is indeed small. But what's so small? Let's compare it to the sun, and when we talk about the sun, let's compare it to the sun. The Sun is 1.3 million times larger than the Earth...... We will now be the Sun, Jupiter, Saturn, Neptune, Earth...... These are pulled into a straight line, let's take a look. No, this is the Earth. The Earth has become a tiny dot in front of the sun. ”

This comparison is very clear and vivid.

The eyes of the friends who were watching the live broadcast were shining, and they watched it with relish.

"Of course, it's not over yet. Is there only the sun in the whole universe, no, no. We know that the galaxy we are in 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 has become a tiny dot in front of the Milky Way. ”

A few PPT pictures flipped over, and many people felt eye-opening.

Of course, the spectrum is not over yet.

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

"Still, that's good, because in this group of galaxies, we can still see our Milky Way. So, let's compare a larger group of galaxies. For example, this Virgo supergroup, in which we are located, has also become a point. As for the Milky Way, it is no longer visible on this diagram. ”

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 picture of the universe drawn by a scientist, see, here is densely packed with stars. However, this is said to be a star, but it is not a star either. Each of these points here is a huge supergroup of galaxies......"

At this point, everyone in the live broadcast room was completely stunned. However, Mo Bai has not finished the introduction: "Oh, I'm sorry, I made a mistake. This cosmograph is not really a universe, it is just a universe that we can see. So, how big is the real universe, and the universe we see is like the stars in this picture compared to the real universe. ”
