After listening to Han Feng's words, all the students present quieted down, and even breathed lightly.

Because the students are so curious about this question.

Out of thin air, such a big bubble appeared, close to the height of the Eiffel Tower, colorful, full of unknowns!

"Before I talk about what this thing is, I need to give you something to popularize science. Han Feng turned on the projector, and a very classic picture appeared on it - it was Einstein's wormhole theory analysis diagram.

"I believe everyone knows the concept of space-time wormholes, right?" Han Feng pointed to the picture and said, "Wormholes are also known as Einstein-Rosen bridges, also translated as cavities. It is a narrow tunnel that may exist in the universe that connects two different space-times. Theoretically, a wormhole is a spatial tunnel that connects two distant space-times, just as a whirlpool can bring the local water surface closer to the bottom of the water, and can make two local spaces that are relatively far away instantly get closer. ”

"Of course, the knowledge about wormholes is actually a very high-end knowledge, and you only need to understand it a little. ”

"So, what is this bubble that appeared in the southeast area of Shencheng?" Han Feng looked around the audience and said with a smile: "In fact, it is similar to a wormhole, but the specific theory cannot be explained by our current basic scientific theories. ”

"Director Han," a student below asked, "I know about wormholes, but shouldn't it be a hole? Why is this a ball?"

"It's actually very simple," Han Feng clicked on the projector again, and a rotating picture appeared on it.

On the picture, at the beginning is a plane, and in the middle of the plane is a hole for a prototype.

And then when the plane starts to spin, the hole before it becomes a ball.

Han Feng smiled: "It's said that it's a hole, but it's actually just an image we made to facilitate explanation." A circular hole in a two-dimensional plane becomes a ball when placed in three-dimensional space. ”

So that's it!

The students present nodded their heads.

People who have watched the science fiction movie Interstellar have basically heard of the ball theory of wormholes, and those who have not seen this movie will be easy to understand when they listen to Han Feng's explanation.

At this time, the students were combing through the knowledge they had just acquired, and at this time they found a very important point.

People in the world have named this thing, so that is to say, in the world, this small wormhole in Shencheng, that is, this Alien Bridge, is not the first to appear!

"Director Han," another student asked, "This ...... of our Shencheng Alien Bridge, not the first one, right?"

"Yes. Han Feng nodded and said, "It's really not the first." At present, there are eighteen Otherworldly Bridges that have been identified and recorded in the world. This one of our Shen Cheng is the nineteenth. ”

The students below suddenly let out a "wow"!

It's actually the nineteenth, so the first eighteen should have been controlled?

"Okay," Han Feng pressed his hand and continued, "Everyone be quiet. Next, I'll talk about this Alien Bridge, what is going on. ”

"The first appearance of the Alien Bridge was in October last year, in the Sahara Desert in Africa. At that time, when countries around the world discovered it, they sent scientists to analyze it. I can't go into the details of the specific situation, but the news I can reveal to you is that this Otherworldly Bridge is indeed connected to an otherworldly space, which is the otherworldly otherworld of the otherworldly bridge I just told you. ”

"This Alien Bridge in the Sahara Desert connects to Alien Realm No. 1. Inside Alien Realm No. 1 is a vast continent. The report issued by the armies of the various countries that passed through the Alien Bridge revealed that the area of this continent was about 300,000 square kilometers, and it was floating in the universe. ”

it!

As soon as they heard the news, all the students below were stunned!

A continent of 300,000 square kilometers floating in the universe is too mysterious, isn't it?

The following instant fry, many students began to use their brains-

"How does this sound similar to the Outlands of World of Warcraft?"

"It's a bit similar, but it's also a bit like a planet in the three-body problem, the kind that has been torn to pieces by stars!"

"Is there an atmosphere, is there water, is there life?"

The students' questions can be said to be all kinds of things, and they discussed for more than ten minutes, and then Han Feng coughed lightly.

"Alright, let's be quiet. Han Feng smiled and said, "I can answer everyone's questions the same." First of all, this continent is indeed similar to the outer lands in World of Warcraft. Don't be surprised, after all, a lot of human imagination is concentrated in games, movies and television novels, and I use this kind of familiar and specific image to make a comparison, which may make everyone have a clearer impression in their hearts. ”

The students nodded together.

Indeed, with pictures from film and television game novels, it is much easier to understand.

"Then, everyone just said that it was torn apart by the stars like the three-body problem," Han Feng continued: "According to the report that came back, it's almost the same. This continent floats in the universe, and it's not just one. This has been confirmed after the appearance of the Twelfth Atlas Bridge. In other words, these alien realms are made up of a pile of fragments of planets floating in the universe. However, there is still one point that has not been confirmed, and that is that it is not clear what the central region of the celestial body made up of these planetary fragments is. Of course, it's also possible that what we learn is only a drop in the bucket. After all, in this strange area, we may only see 1 in 10,000 things. ”

Speaking of this, he paused and continued: "In addition, the proportion of the awakened essence in the alien realm is more than ten times that of the earth, that is to say, the aura is more than ten times that of the earth. Under the influence of the awakening liquid, all radio wave things are ineffective, and the burning speed of gunpowder is one-tenth of that of the earth, which also makes thermal weapons such as firearms and missiles basically unusable. ”

Hearing this, the students below were curious again.

It is impossible to use electronic devices, and thermal weapons are not easy to use, but the aura is very strong......

How is this a bit similar to the fantasy world in the novel......

At this time, a classmate asked an extremely critical question: "Director Han, the other world...... Oh, is there a creature in another land?"

This question can be said to be the most concerned by the students present.

And Han Feng obviously didn't have the habit of selling Guanzi, so he nodded very affirmatively: "Yes." ”
