Chapter 404

On earth, people use mobile phones to make phone calls and send QQ and wechat messages over the wireless network. It seems that they are absolutely timely. They only need to wait for problems such as network speed when transmitting files.

But that doesn't mean it's really real-time.

The communication between people is a signal running, and the essence of the signal is electromagnetic wave. The transmission speed of electromagnetic wave signal is the speed of light. In front of the speed of light, the distance on the earth is very small. Even the communication across an ocean can sound like face-to-face communication without delay, That little bit of electromagnetic wave signal takes time to run, which can not even be felt by human fragile sensory organs.

However, not on a starry scale.

What happened one light year away came to the earth with information and was observed by people. This time takes a whole year. In other words, if two people talk across a light-year, and the two people talk at the same time, the two sides of the conversation must wait a year to hear what the other party says, and it will take another year to hear the reply again, unless quantum or hyperspace communication technology is used, This technology may be applied to the information transmission between the stars, but it is difficult to be applied to the exploration of space.

Therefore, although the fleet has mastered certain quantum communication technology, it can not be applied to the exploration of interstellar space. Therefore, the astronomical observation and investigation of the earth will be greatly limited.

This transition fluctuation was discovered 17 billion light-years away, and the information feedback was received four days ago, that is, the last day of the previous year, the day before the first spacecraft of Bilin appeared.

Of course, we should take into account the concept of space we just talked about. Light carrying information runs over 17 billion light-years to the earth in at least 14 to 15 days.

In other words, the nearest neighbor star appeared in the outer ring space of the solar system at least 18 days ago!

They... Have already arrived.

When presenting the data, each Observatory has already checked to determine that they are not the ghost ship fleet that entered the solar system from the direction of neighbor star.

Combined with the above, the biggest problem at present is

Where is the nearest star fleet now?

They arrived in the outer space of the solar system 18 days ago, and did not disturb any monitoring network under the extraterrestrial space fleet in these 18 days. Then they may appear anywhere!

Su ran felt a cold chill rising from his back.

It's still too short, too short.

He has only space to arrange the defense line of the earth and the moon, and outer space can only barely take care of a little.

It is impossible for a few years or even decades to really make the whole solar system spread all over its "eyes", because the area is too large and there are all kinds of stars. It is not easy to make space like an iron bucket.

Fortunately, this cold feeling of ice was soon completely expelled by Su ran. He took a deep breath and said: "it was conveyed to all countries and observatories. I hope they can continue to search based on this discovery, and try to find their traces whether they can or not."

The nearest star fleet is very careful. At least according to the current feedback information, the transition 17 billion light-years away from the earth is their last transition, because closer is the region of the solar system. It is obvious that they are deliberately "hiding" themselves, and as long as they want to hide and enter a silent state, With the earth's pure telescope observation level, it is almost impossible to find them, but Su ran will not give up any details, even if it knows that it is almost impossible to find them by observation.

Further forward, they search where they come from. The transition information at the far end is still running on the road, but they have not reached the earth, and they can't find their location in the future.

But

This information is not useless.

It is almost self-evident that Bilin is making peace on the bright side, but secretly moving a large fleet, even making a big circle and cautiously entering the surrounding areas of the solar system.

The atmosphere on the bridge was fairly good, because the strength of the fleet and the calmness of your commander were seriously regarded by everyone.

At this time, Li Yilan said: "commander, the Russian Federation, China, the United States and other major powers and large survivor forces all hope to hold an emergency global joint meeting, hoping to..."

Su ran said, "I know. Turn on the remote conference mode. I'll go in a few minutes later - has the information been transmitted to old Qiao and Lin Yuandong? I want to connect communications. "

Li Yilan nodded and immediately responded.

Su ran began to operate and connected the two battle group commanders of the third and fourth Cloud City battle groups in Jupiter's orbit.

There is no picture, only sound.

Lin Yuandong's voice also changed a little, a little nervous, and said: "is it possible that this is a cautious move of the nearest star fleet? Just as we are cautious about them, they just keep a hand against us? "

This logic is reasonable. Su ran thought of this for the first time. After all, from the situation of the previous three days, the nearest star fleet can be said to be quite cooperative, and from the cautious perspective of alien civilization, it is not impossible for them to guard against the earth

So

Su ran Lengsu said, "yes. We can also understand this, but I want you to be ready to fight at any time. In the past three days, we have comprehensively scanned the 11 ships of the ghost ship fleet of Bilin star, and accumulated a large amount of important data of enemy ships. Although we don't know ourselves and the enemy, I hope you can eat the ghost ship fleet in the shortest time if there is a war! "

Lin Yuandong and Qiao Xiangchen, who are on the two flagship ships far away in the orbit of Jupiter, listened to Su Ran's cold and killing voice with a slight chill in their hearts and said in unison: "received! Your excellency commander! "

Su ran immediately cut off communication. He had planned to quickly access the global joint conference, but he was silent, but he contacted the spore life still in the ground laboratory.

The representative sent by spore life is still Su Ran's "old acquaintance" Liu Tingting. There is almost no expression on her face. As a partner of civilization, Su Ran has always shared the news about the adjacent star fleet with them. Therefore, at this time, they also know the situation. Su ran asked straight away, "what do you think?"
