Ever since his body and soul were baptized by Gaia's soul energy, Luo Tian always felt an inexplicable sense of crisis from time to time. Pen ~ Fun ~ Pavilion www.biquge.info is this sense of crisis, urging him to quickly stay away from the earth and the solar system. Not only Luo Tian, but even everyone on the "Daystar" spaceship had this similar premonition, an unspeakable premonition that penetrated deep into the soul.

All the wind and grass within the radius of one light year of the "Daystar" spacecraft could not escape Luo Tian's perception, and no anomalies were found around, but Luo Tian did not relax in the slightest. Compared to the vast universe, the scope of one light year is so small that when some cosmic catastrophe erupts, you will have to face death before you even know it.

Luo Tian is not omnipotent, at least he can't predict the future. The sense of unknown crisis has always haunted him, and he can't do anything but passively wait. This feeling of not being able to do anything and only waiting silently made Luo Tian feel extremely upset.

It is not uncommon for the universe to be full of dangers, and disasters that can affect one galaxy or even several large galaxies. Although the frequency of their own outbreaks is very low on the scale of civilization, on the scale of the universe, the frequency of such disasters can be called frequent.

According to the current human understanding, the cosmic catastrophe that can affect human beings in a long distance should be the gamma-ray burst caused by supernova explosions or other violent celestial activities. The high-speed, high-energy gamma rays that sweep across the starry sky are an absolute nightmare for all carbon-based creatures.

Astronomers in the Earth era once said that a huge star about 8,000 light-years away from the Earth, codenamed WR104, could have a supernova explosion at any time, and the Earth was in the path of a dangerous gamma-ray burst, and a large number of gamma rays would reach the Earth, which could destroy a quarter of the ozone in the Earth's atmosphere.

Not to mention whether the inexplicable sense of crisis comes from this huge star, which has lost the protection of the earth, and the "Daystar" spacecraft's ability to resist any cosmic catastrophe will be infinitely reduced. Of course, if the crisis really came from this star, then the "Daystar" spacecraft still did not escape its eruption trajectory.

The lower civilization is such a tragedy, even if they know that the crisis is coming, even if they know the route of the crisis, they still have no ability to avoid it. Once a supernova explosion occurs on that star, a gamma-ray burst will sweep across the star field near the Earth for fifteen thousand light-years, and even if An Ruoxuan is given 8,000 years to avoid this explosion.

Supernova explosions are not uncommon in the universe and can even be said to be very common. Of course, this commonality is still on the scale of the development of the universe. Supernova created everything, and almost all the elements on our earth came from the remnants of supernova explosions, and the heavy elements of iron, gold, and silver were all products of supernova explosions.

All the stars in the universe are like giant nuclear reactors, and the nuclear fusion reactors in the stars use hydrogen, the simplest and most common in the universe, as raw materials, and the reaction fuses hydrogen atoms together to produce helium and energy. When hydrogen is depleted, stars fuse helium into carbon, which in turn turns into oxygen to continue burning.

When stars like the sun start producing carbon, they slowly embark on the road to extinction. The Sun will gradually turn into a red giant, and eventually the inner core will collapse to form a white dwarf star about the size of the Earth. The mass of the Sun is too small to form supernovae, and most of the supernovae in the universe come from another situation.

The solar system in which humans live is a different kind of thing, with only one star. In fact, most of the stars in the universe occur in pairs. If one of the two stars becomes a white dwarf, it will steal material from the other star if it is close enough, slowly absorbing the hydrogen and helium from the other star.

The white dwarf draws more and more fuel from its companion star, and it will become heavier, denser, and more unstable. Inside the white dwarf, carbon and oxygen atoms are about to coalesce, and the white dwarf is like a giant thermonuclear bomb that is transforming into a type 1a supernova.

Eventually, the white dwarf absorbed enough fuel from its companion star to enter a state of nuclear overload, and the carbon and oxygen inside it began to transform into an extremely common but extremely dangerous element. When white dwarfs begin to fuse carbon and oxygen into iron, it's all over.

The white dwarf exploded, and a large amount of iron would splash into space at a very high speed. Type 1a supernovae play an important role in the evolution of the universe, and it is an important source of iron in the universe. Other, heavier metals such as gold and silver, come from the explosion of a larger single star.

Supernovae can be said to be the cornerstone of the creation of cosmic civilization, and similarly, supernovae can also be said to be the murderer of interstellar civilization. The gamma-ray bursts generated by supernova explosions that swept across galactic space destroyed one civilization after another in their infancy, and only those who were lucky enough to develop technology to combat the catastrophe during the window period of a supernova explosion.

Powerful gamma-ray bursts can kill a certain range of cosmic life, and what is more deadly is that gamma-ray bursts still occur regularly, which is bad news for cosmic life, because this situation can prevent cosmic life from evolving into advanced species.

Gamma-ray bursts may have cleared about 90% of the galaxy's space, and the Milky Way was also hit by gamma-ray bursts. Gamma-ray bursts come from bursts when stars enter the last years of their lives, and their powerful radiation can damage DNA and cause planets to lose their atmospheres.

In the last 500 million years or so, gamma-ray bursts in the Milky Way have rendered much of the galaxy unusable, deadly gamma-ray bursts are very frequent in the Milky Way, and gamma-ray bursts can occur around the Earth, but the gamma-ray bursts near the center of the Milky Way are more powerful.

From the distribution characteristics of galaxies, it can be seen that life is suitable for survival at the edge of large galaxies, and the space environment here is the safest, so huge galaxies are actually only suitable for survival near the edge, and such space accounts for about 10% of galaxies.

According to the observations of space telescopes from previous Earth periods, gamma-ray bursts occur almost every day in the universe and in random directions, and if a planet with life is unfortunate enough to be in the path of a gamma-ray burst, then life on this celestial body will be wiped out.

Luo Tian wasn't sure if he could resist gamma-ray bursts, but he definitely wouldn't leave An Ruoxuan and them behind. As a last resort, Luo Tian would transform them into soul templates and introduce them into the world of telekinesis. But if you do that, it means that the modern human race on the earth has been completely extinct.

What Luo Tian hopes now is to be able to figure out the source of the crisis, and sometimes, the technological equipment is stronger than the cultivation ability. With the help of the spacecraft's deep-space exploration equipment, it should be possible to detect possible sources of danger. If the situation is really critical, Luo Tian may directly take the "Daystar" spacecraft for space travel.
