Li Nan really couldn't figure out what he was excited about this time, what he just said was worth his excitement, and after thinking about it carefully, he didn't feel that he had just said anything wrong.

How could his abnormal behavior not alarm the other people on the side, especially the space-time wormhole and the like that he was shouting loudly, Professor Ross, who had taken a small bowl of shrimp meat and was eating it, had already alarmed Professor Rose, who had taken a small bowl of shrimp meat on the side and was eating.

How can I not care about this kind of topic that is related to my major and has something to do with my research direction! I quickly put down the bowl in my hand and ran over in small steps to ask what happened.

Pi Gudong was pestered by Professor Ross for a while before settling down, but there was still an indelible smile on his face, and that kind of excitement could not be disguised.

"What do you mean by space-time wormholes? Could it be that we didn't come here through space wormholes this time?" Professor Ross finally asked the question he was most concerned about.

Li Nan thought about it for a moment: "Aren't you majoring in ancient languages?

"The major in ancient languages is a minor, and I also major in physics, and it is also space physics. See Ross? Ross is supposed to be majoring in engineering physics.

Physics is so huge and there are too many branches, if you study them all, you won't be able to learn them all, and you can only major in one aspect. Pi Gudong is very proud of his major, even in his time, space physics was also at the forefront of the times.

There is no way, but if you want to break the speed of space beyond the speed of light, you must involve space knowledge. Because if you can't touch some space common sense, faster-than-light flight is simply impossible!

"Wait, don't brag about your profession first, first tell me what you just meant by the space-time wormhole, could it be that we didn't just travel through space this time?" Professor Ross looked at him as if he was familiar with him, and directly interrupted his thoughts about continuing to talk, and asked about the key points he cared about.

"Actually, when I first woke up, I noticed, especially when I first saw him, I noticed the problem of time, we saw that more than a hundred years had passed on our watch, and the spaceship did look like it had gone through many vicissitudes of life.

But you see, these things he brought with him are obviously very new, although they can't be considered brand new, but they are not more than a hundred years ago.

Look at the surrounding environment, including the overall environment of the entire planet, you have also studied planetary ecology, like this kind of environment can not be created in a year or two, at least more than fifty years, but in this environment, it is impossible to have a perfect industrial base, not to mention that at the beginning, there was basically no industrial base on the home planet, can you understand what I mean?" Pi Gudong felt that he had already spoken in detail, and it stands to reason that Rose, who was born in the same school as himself, should be able to understand.

"I generally understand that I have paid attention to these details, but there is still a big problem.

What do you mean is that we have passed through the space-time wormhole, including our planet, but he has not suffered from the corrosion of time, including some things around him.

The big question now is, why is he an exception? This is unreasonable!" Professor Ross was referring to Li Nan.

What else did Li Nan not understand at this moment? However, their idea was completely wrong, these things were not preserved under the corrosion of time at all, but they were brought from their own home.

But at this time, the eyes of both of them were constantly staring at Li Nan, hoping to get an answer from him, or rather, hoping to find something from him that was different from them.

Li Nan couldn't explain the reason at all, and he didn't understand what space wormhole they were talking about, and he didn't understand the space-time wormhole.

"Didn't you find a problem? If you are experiencing a space-time wormhole, does the space-time wormhole cover the entire small galaxy, or does it cover the planet?

If you only cover the planet, there will be no sun for more than a hundred years, and there should be no life on the surface of the planet, but if you cover the entire galaxy......" Li Nan said that he didn't know how to explain it later, what he was saying so far was only based on his own understanding, but what would happen to cover the entire galaxy?

"In other words, we only need to check if our star is the original star, and we should be able to roughly understand whether we have experienced a space-time wormhole!" Pi Gudong also calmed down, indeed, the little thing he noticed before may only be an exception, or an accident.

"I'm afraid it's hard to observe, this star looks similar to the original star, I only studied planetary ecology, not galaxy ecology, so I can't distinguish it at all.

At least it is not visible to the naked eye at all, which requires the measurement of special tools. Ross wanted to find out the truth, but the reality was not allowed.

But he also knows very well that the most critical place should be on Li Nan's side, as long as Li Nan is willing to tell the truth, things will be easy to explore. But now it seems that he should have something unspeakable, at least, he should be unwilling to explain the specific origin of these things.

Li Nan saw that they were discussing enthusiastically, he couldn't interject at all, and he didn't know how to interject, so he couldn't really tell them what kind of time traveler he was, right?

Inexistent.

"Li Nan, but I don't understand, it's really uncomfortable, then I won't ask you about your specific origin, can you tell me if these things you brought over have passed through the wormhole with this planet?"

Li Nan thought about it, and knew that he had a lot of flaws, in fact, even if he didn't bring those things over, just the clothes on his body, and even his whole existence was a very strange thing.

So I can only say very vaguely: "No, I haven't experienced it, and the things I brought have nothing to do with what you think." ”

"Ahh

Rose was much better, because he didn't have any hope for the plane!
