I'm an almighty star

Chapter 1133 Star Hunter

"Damn it, can't it be, our Huaguo didn't even find a single pulsar?"

"I also really hope that Huaguo can find one."

"No, there are so many stars in the sky, they can find them in America, why can't we in China?"

"Brother, do you think pulsars are the stars we see when we look up at night? Let me tell you, the stars we see at night are all huge stars. Each of them is bigger than the sun, and some are even bigger than the sun. Hundreds of millions of times."

"Uh……"

Facing Tianwen, countless netizens instantly became idiots.

This made many netizens feel a little embarrassed.

"A real pulsar must receive its pulse signal through radio telescopes before we can discover it. That is to say, we cannot see it with the naked eye, or even with ordinary optical telescopes."

"So that's the case. However, we don't need to be so emotional. Isn't it just the discovery of a pulsar, and we in China will definitely find it in the future."

"You thought you only found one?"

"Not one or several. Could it be that there are a lot of pulsars like this in the universe?"

"Of course there are so many, it can be said that the number is countless, but it is difficult for us to find out."

"Then tell me, how many pulsars have we humans discovered?"

"As of now, we humans have discovered more than 2000 pulsars. And scientists in the United States have discovered more than half of them."

"I said, more than 2000?"

"No."

"No, no, you mean, among the more than 2000 pulsars discovered by us humans, our country of China has not discovered any?"

"Yes."

Seeing this, some netizens who didn't think so before were deeply hit.

You know, at the beginning, they thought that there were only a few pulsars, and they were discovered when they were discovered by the United States.

Their strength is strong, we just need to follow behind.

However, looking at it now, Nima, more than 2000 pulsars have been discovered.

But precisely among these more than 2000 pulsars, our Hua country has not found any.

This is no longer something that can be caught up with a single effort.

Looking at the situation, hey, in the field of astronomy, the entire country of China may not be able to hold a candle to the country of the United States in 30 years.

"Is this pulsar really hard to find?"

"Of course it's difficult. You know, although there are countless pulsars in the entire universe, their signals are really too short. And, because we can't see them with the naked eye, we can't see them with ordinary optical telescopes either." Just like Hubble, which is more powerful in the United States, he can't find it either. The radio telescope that can really discover pulsars. This kind of telescope has no optical lenses, and the principle of discovery is not to see, but to Receive the pulse signal with the antenna."

"So that's how it is. By the way, what is this radio telescope like?"

"Here, let me show you the Arecibo telescope in the United States. Most of the pulsars in the United States are discovered by it."

An astronomy enthusiast posted a picture of the "Arecibo" telescope in the United States.

Many netizens couldn't stop screaming when they saw it.

"I'm stupid, why is this binoculars so big?"

"Yes, it's really too big. It seems that the caliber should be 50 meters."

"Shit, I'm all about astronomy now."

There are countless disciplines in the world.

Astronomy has always been a huge and mysterious subject.

It's okay if you didn't know it before.

However, when you try to understand it, you will be deeply fascinated by it.

Not to mention the brilliant starry sky, just this super-large binocular with a diameter of 50 meters is extremely attractive.

"It feels a bit like alien technology."

"Yes, I always thought that the binoculars were a long tube with optical mirrors on them."

"No matter how big it is, the Hubble Telescope is big, but it is only 13 meters, far from being comparable to Arecibo."

Everyone was deeply attracted by the American "Arecibo" binoculars.

"Is there anyone who can explain the specific function of Arecibo?"

"Yes, what is the difference between this radio telescope and the optical telescope, and what is his function?"

"Also, who can explain that pulsar to me in detail?"

The fans who were attracted asked countless questions.

Fortunately.

Although Hua Guo's research in astronomy is not very good, he still knows some common sense of astronomy.

It was the same astronomy researcher who responded to all the netizens one by one.

"First explain pulsar. Pulsar is a kind of neutron star. Its mass is extremely huge, but on the contrary, its size is very small, and some are even as big as pawn balls. But don't look at them It looks like the size of a Bingbing ball, and its mass of 10 earths may not be able to reach it. Of course, it has not yet reached the density of a black hole. Scientists call this kind of star with a density slightly smaller than a black hole a neutron star. However , not all neutron stars are pulsars. The neutrons that emit pulse signals are called pulsars.”

"Explain the role of pulsars again. Because pulsars will find periodic pulse signals like lighthouses. Therefore, it has a huge role for astronomers to study the universe, as well as the evolution of stars, and to locate cosmic coordinates and time. Therefore, the astronomy community regards scientists who discover pulsars as star hunters."

This astronomy researcher is not an expert, but he can still do simple astronomical science spectrum.

"It is precisely because of the role of pulsars that people have been looking for pulsars. Because pulsars cannot be seen with our naked eyes, we can only find pulsars by receiving signals. Therefore, scientists have Radio telescopes were made for this."

"However, radio telescopes are not just for finding pulsars. They are also useful for finding other celestial bodies in the universe, such as dark matter hidden in the universe, black holes, exploring the edge of the universe, and searching for aliens..."

"Of course, the radio telescope is not just for astronomy. It plays a pivotal role in weather forecasting, high-precision navigation, positioning, measurement, including aerospace engineering, rocket launch..."

Although the astronomy researcher's introduction is not very detailed.

However, even this content is enough for countless netizens to digest.

"I thought the astronomy in the United States was very good, but now I see it, damn, this astronomy can be directly used in spaceflight."

"The principles of aerospace and missiles are the same. Now I know why the missiles of the United States are so powerful."

"With such a powerful radio-type telescope, can it not be strong?"

"It's not just aerospace, let's take a look at their GPS positioning system. It is precisely because of the technical support like Alessi Bowang glasses that they can achieve global positioning with GPS. Well, understand the positioning function of mobile phones, use It is also GPS global positioning technology."

"Actually, I have said so much. It is about astronomy, binoculars, and pulsars. But in fact, it is about technology, and it is about the strength of the entire United States."

To the point.

Countless Chinese people opened their mouths and fell silent.
