The third thousand three hundred and twentieth chapters of the star's self-protection trick
"This..." Everyone was stunned and completely stunned by Ling Daozi's words!
They seem to have a certain understanding of the role of light, but not yet to a very thorough level, so they still feel a little confused, but fortunately, they do understand more than at the beginning...
Xiaoxing continued: "In fact, you can also understand that the things we see are all things in the past, brought to our eyes by light. However, if the distance is close, because the speed of light is extremely fast, it is so fast that we can
We don’t feel that what we see in front of us is in the past at all, but we think that what we see is now! However, if the distance is far enough, it will take a certain amount of time for light to bring this information to our eyes. Take advantage of this
, we can observe and calculate the actual speed of light!"
Yanna was a little stunned and said: "It turns out that you calculated the true speed of light through long-distance observations and calculations!"
Xiaoxing nodded and said: "This is indeed a main method! Of course, there are other methods that I won't talk about one by one. Generally speaking, the speed of light is relatively constant, but under different environmental conditions, the speed of light will also vary.
Changes, for example, when the medium through which light passes is different, its speed will also be different..."
"Oh?! What's the difference?!" Yana asked urgently.
Xiaoxing said: "The speed of light in the starry sky is measured through observation, but this speed will be slightly weakened in the air, and will be greatly weakened in the water. In ice, in other transparent
In all substances, the speed of light will be affected to a greater or lesser extent, but the speed of light we usually talk about refers to the speed in the starry sky of the universe."
"So, the light year you just mentioned refers to the distance that light travels through the starry sky in one year?" Yanna asked.
"Yes! This is almost the fastest speed of light, so this distance will be extremely far away. For a galaxy, the farthest distance inside it can reach tens to hundreds of light years without any problem!" Xiao Xiao
Xing said.
"Oh my god..." Everyone exclaimed when they heard this, and they were all dumbfounded. They simply couldn't imagine...
Looking at the Wolf Galaxy and Turia Galaxy in the light curtain in front of them, they could not imagine that they would be so huge, so huge that it would take tens to hundreds of years for light to travel through them!
What a shocking behemoth!
What shocked them even more was that, as the core planet of the galaxy, it had such a strong pull that allowed so many star groups and scattered stars to surround it and be driven by it...
Yanna took a deep breath, calmed down his emotions a little, and then asked: "Xiao Ling, just now you said that the Wolf Galaxy might catch up with the Turia Galaxy in ten thousand years. If this really happens,
Now, what will happen?!"
When everyone heard this, they all stared at Ling Daozi closely. Their hearts were so high that they were almost in their throats...
Everyone knows that this is definitely not a good thing, but when two giant galaxies collide, they can't imagine how the result will evolve, and they don't dare to imagine it. They can only pray secretly in their hearts...
Xiaoxing was secretly happy, but said: "Senior asked a good question! To understand the evolution of this galaxy merger, we must first understand the problem of the core planet! For the galaxy, other ordinary stars are just kidnapped by the core planet
Just moving forward, the life and death of these ordinary stars is not too important to the core planet, even..."
"Even what?!" Yana asked urgently.
"Actually, ordinary stars that are closer to the core star are very dangerous. Many ordinary stars actually play the role of being swallowed by the core star and providing energy supplement for the core star. You can take a look here..."
Xiaoxing said, calling up a picture and saying: "This is the core area of the Turia Galaxy. You can see that there are more stars here, that is, the sun, so the brightness here is brighter than the surrounding areas.
To make it brighter, in addition to the sun, there are countless other stars, all of which are orbiting the core area..."
Andavi stared at the screen closely and said, "Xiao Ling, it seems that this place is far away from our Turia star field, right?"
"Yes, the reason why this galaxy is called Turia Galaxy is because of you, but in fact, the location of Turia Star Field in this galaxy is quite remote, far away from the core. However, you should be fortunate that it is exactly
Because you are far away from the core area, you are very safe now. If you are around the core area, you may face the danger of being devoured by monsters in the core area in the near future..." Xiaoxing said with a smile.
"Wo..." Everyone was so shocked that they broke into a cold sweat!
Yun Han listened for a long time and felt that he finally had good news. He couldn't help laughing and said: "Xiao Ling, what you just said almost scared me. Fortunately, you now say that our clan is very safe!"
"Holy Emperor, rest assured that the Turia star field is indeed very safe at present. Even if a major galaxy collision does occur in the future, there will still be a long time for it to exist and develop..."
"That's good! But why didn't I see the so-called monster planet in the core area?" Yun Han asked.
Xiaoxing said: "How can such a monster planet be easily seen? In fact, we can't see it with our naked eyes!"
"But why?!" Yunhan said in surprise.
"Holy Emperor, we have said before that light is the messenger of the universe. When we see something, we need light to bring us information. If there is no light, it will be difficult for us to see something, unless we compare distances.
We can still sense it through our spiritual sense, but now we are too far away from the core area, so it is impossible to sense it there!" Xiaoxing said.
"Oh? So, is there no light in the core area? This is impossible, right? The light of a monster with such high-level energy should be extremely eye-catching, right?" Yun Han asked curiously.
"The Holy Emperor's words make sense!"
"The greater the energy, the brighter the light!"
"It's like the Tiangang gem. How much light does it have? Its energy is extremely high!"
"Yes, just like the powerful powers of the universe have their own halo, but ordinary people are not conspicuous at all..."
"That's right..."
The people in the palace all agreed. After all, in their opinion, this principle is almost common sense...
Xiaoxing smiled and said: "Seniors, the greater the energy, the brighter the light. This is not a truth. I wonder if you have noticed that some people will appear radiant and extremely dazzling when their cultivation level is not very high.
There will be traffic jams on the road, and countless people will rush to watch. However, when their cultivation level reaches a higher level, the light on their bodies will become restrained, and the whole person will not shine as brightly as before.
Rather, it is natural and simple, with the inner meaning of Taoism... This can be called returning to nature!"
"Back to Basics?!"
"right…"
"Some people were so radiant when they first broke through, but then they faded away..."
"However, when your cultivation level is low, you can't control the Dao light and spiritual light on your body well, so you let these lights radiate out unscrupulously. But when your level is high, you can control it well.
, but it becomes more natural..."
"That's true..."
When everyone heard Xiaoxing's words, they suddenly realized something and started to agree...
Xiaoxing continued: "Everyone is right! The core planet is extremely powerful, so powerful that light can be absorbed by them and cannot escape at all! In other words, these monster-level planets themselves will also emit light.
Yes, but the light was sucked in by them and could not escape. Since there is no light coming out, we cannot see the monster planet itself through the information brought by the light. Therefore, now we will find out where
There seems to be nothing in the core area of the film..."
Yun Han finally understood and couldn't help but nodded: "I see! But since we have never seen a monster planet, why do you think there is a monster planet there?"
"The Holy Emperor asked a good question! How to judge that there is a monster planet in the core area, but we cannot make conjectures out of thin air, because doing so would be a bit metaphysical, and we still need to infer through some evidence!" Xiaoxing praised.
"Evidence? I wonder what evidence you found?" Yun Han asked urgently.
"Holy Emperor, look, we just said that the stars in the core area are denser and the brightness is several times higher than that in the surrounding areas. This is one of the evidences. Because the power of the monster planet is extremely huge, it can attract and capture it.
More ordinary stars stay around him..." Xiaoxing said.
"Then...what about the second one?"
"The stars in the core area move several times faster than the surrounding stars. The closer they are to the center area, the faster they move. This is the second evidence!" Xiaoxing said again.
"Oh? Why does this happen?" Yun Han said in surprise.
"Holy Emperor, these stars are doing this to save themselves! Because the pulling power of the core monster planet is too strong, it exerts a huge attraction on the surrounding stars. If you don't save yourself, the surrounding stars will be attracted by it and be shattered to pieces!
"Xiao Xing said.
"That's true... Could it be that the way for them to save themselves is to speed up their operation?!" Yun Han asked suspiciously.
"Yes! By speeding up the operation, an outward centrifugal force is generated. This centrifugal force can happen to offset the pulling force of the core monster planet, so you can safely stay in the core area!" Xiaoxing said with a smile.
"Wo..." Everyone suddenly understood after hearing this, and they couldn't help but let out a sigh of relief. They felt that they had been worrying about those stars in vain just now. It turned out that they had such a unique trick that they could use to protect themselves...
Andavi praised: "It turns out that they accelerate their rotation in order to generate such an outward centrifugal force. How clever!"
"When you're in the world of martial arts, you can't protect yourself without a trick..." Xiao Xing said happily.
