Although Professor Xie's status in the astronomy community was very transcendent, and Ye Fei was willing to give him the treatment he deserved on the Xinyuan, he was a non-military person after all, and he was completely incapable of interfering in the command of warships and fleets, and it was not strange that unreasonable requests were directly vetoed.

Don't look at the number of spaces that the fleet has obtained so far, it is still very normal, but Ye Fei and the other captains agreed that the next seven light years will be the most dangerous journey of this voyage, so the fleet did not get enough numbers as in the past to set sail immediately, but stayed in place for a long time of in-depth observation, but a group of Qiu Ba knew more, and it could not involve the astronomical field of such a high-end atmosphere as a supernova explosion, so in the end, it was still necessary to listen to the opinions of professionals before deciding on the next action plan.

However, when it came to the safety ahead, even Professor Xie and others, who were anxious to get close to Betelgeuse to get first-hand information, were numb and stunned for a while.

The devil knows what's in the nascent nebula!

Don't look at the cosmic space behind the shock layer to return to normal, but that is only relative to the shock layer, the closer to Betelgeuse, the more complex the space environment becomes, at this time Betelgeuse has long been wrapped in a dense nebula spanning more than five light years, and the fleet cannot see its current appearance at all.

The nebula of the nova is still slowly expanding outward, and according to Professor Xie, this nebula will form a magnificent supernova remnant in the near future.

"The speed at which this star is spreading is too slow, it's only five light years in more than 200 years? When will it become a supernova remnant that spans tens or hundreds of light-years? Ye Fei asked curiously at the "little nebula" in front of him.

The supernova explodes, and the nebula spreads even if not at the speed of light. It shouldn't be much worse than the speed of light, right? What does it take 200 years to expand by five light years?

"Not surprising at all." Professor Xie said flatly, "No matter what kind of supernova theoretical model is followed, the supernova explosion of Betelgeuse of this quality level will eventually form at least neutron stars, and we know that the gravitational attraction of neutron stars is very strong, and the reason why a small area of dense nebulae is formed is because neutron stars are misers, and the explosion made it have to throw away most of its family property, and it is really reluctant to have the last bit of family money." He had to use a strong gravitational force to grab the last part of the material thrown back by the explosion. ”

Professor Xie stretched out his hand and made a grasping motion: "A lightweight substance like a gas is always the first to be thrown out when it explodes. Fly fast and far. Heavy elements with relatively large masses are also thrown at a slower speed and are more likely to be affected by gravity and stay. If it weren't for this, even if the explosion formed a super-heavy element, it would have been thrown out dozens of light-years long ago. Which round will we come to mine? ”

Ye Fei felt his temples jump wildly: "That is to say." This airtight nebula should contain a large number of heavy elements synthesized during supernova explosions. If Betelgeuse is any good, there may be planetary wreckage. To paraphrase nautical terms, the environment in the Nebula. It's like a fog on the reef in a strange sea, and if you break into it like this, you might collide with something. ”

He really hesitated, and even had the idea of wiping his head back, and as soon as this idea appeared, it was like a parasite firmly rooted in his heart, and it continued to grow and develop.

"That being said, but I don't think it's as dangerous as you think." Professor Xie's idea is completely opposite to Ye Fei, "The operation of galaxies is regular, we have been in contact with thousands of galaxies, and we know the laws of celestial bodies very well, generally speaking, as long as there are planets, the planets basically orbit in the ecliptic plane, and the angle between the ecliptic plane and the stellar equator is usually not too large!" ”

Professor Xie stretched out his hand and drew a circle to make a disk-shaped plane gesture: "When a supernova explodes, the matter should be mainly concentrated in a certain angle of the ecliptic plane, as long as the fleet is close to Betelgeuse along the radiation edge of the pulsar axis, the probability of distress can be minimized." ”

As soon as this strange theory got into Ye Fei's ears, Professor Xie's originally tall image in Ye Fei's heart immediately collapsed: "To the minimum? That's still dangerous! ”

Flying close to the radiation zone? What are you kidding, if you break into the nebula directly, you may not be able to hit anything, but if you break into the radiation zone, you will be 100% dead.

It's like dancing on the tip of a knife, it's death.

If you don't die, you won't die, and Ye Fei won't even hear this wise saying.

People are old and ghosts are old and slippery, Ye Fei's appearance fell into Xie Guohui's eyes, and the alarm bell in his heart was loud.

The fleet had arrived only seven light-years away from its target, and if he turned around and returned at this time, he would not be able to close his eyes. But although Ye Feiren is young, he is a guy who has fought many big battles, and his hands are stained with the blood of foreign races, he is definitely not a cowardice with soft ears, if he really makes up his mind to return home, unless there is a miracle to contact the base Xinghui, it will be difficult for anyone's persuasion to shake his determination.

At this moment, not to mention the soldiers in the fleet, even the experts brought by Professor Xie have many of them flinching when their lives are threatened.

"Captain Ye, can't you come up with a safe way?" Professor Xie's brain is running fast, but where can he come up with an effective solution for a while? I had to start by saying that it was useless to delay the time.

"Unless the safety of the route is determined." Ye Fei's tone was indifferent, but no matter who he was, he could hear the resoluteness in his words.

"With such a large fleet, can't you open the way with weapons?" Professor Xie asked unrelentingly.

"It's okay to get out of the way, but my battleship can't fly faster than light speed and shoot forward at the same time, so it can't fly at a normal speed, right?" Ye Fei asked rhetorically.

If you enter in the conventional way, what weapons do you need to open the way? Just turn on the radar and fly in.

"Xiao Ye, it's not easy for us to catch up with the supernova explosion, if we miss this opportunity, I don't know when we will encounter the same opportunity again next time, although I can't tell what I can get now, but I believe that studying Betelgeuse is of great significance to the development of our astronomy, so please think of a way again." After that, Professor Xie looked at Ye Fei with expectant eyes.

There are very few people who are good at communicating with people, and Professor Xie is no exception. He really couldn't think of any reason to convince Ye Fei, so he simply played the emotional card. (To be continued......)
