Chapter 1113
In Shen Bei's eyes, the last guarantee for mankind is not Titan, but spacecraft capable of interstellar travel.
Regarding the current dim and unclear situation.
In addition to the "possibility" of a battle between the World-Destroying Starship, the Shadow Immortal, and the Tiangong,
There is also a latent but almost obvious deadly threat.
That's a cosmic ray burst.
This is the information Shen Bei learned when he read Bermula's memory.
In his conversation with Lingxi Zhiling, he got a positive answer.
There is a fifty percent probability that the Earth will enter another mass extinction period.
That is a supernova explosion.
According to Lingxi Zhiling, a relatively large star will explode when it finally dies.
One of these characteristics is that the flash of light produced by any massive stellar explosion will be brighter than the galaxy in which it exists.
That is to say, when a star explodes, it can be seen in every corner of the galaxy.
However, so far, stellar explosions in the universe are relatively far away from the earth and are difficult to see with the naked eye.
The interesting point here is that even if you see it, its explosion process is very slow within the field of vision.
This ongoing process will likely take several months.
Essentially, this is because the faster the speed, the slower the time.
What we can see with the naked eye is that it is moving in high-speed slow motion.
And in the center of the explosion, it only took a moment.
When a star explodes, it ejects matter and creates a nebula.
Logically, these nebula fragments should not emit light, but when they explode, flashes of light will appear. These flashes and fragments will float together in the universe and can continue to shine for tens of thousands of years.
Interestingly, the sun, as a star, will not explode because... it is too small.
Here, Shen Bei also learned a concept: the smaller the star, the longer its lifespan.
However, the sun is already halfway through its lifespan. In five billion years, it will continue to expand, and its color will change from its current golden yellow to dark red.
After expansion, its maximum length can swallow the earth.
Then the sun will begin to shrink, becoming a white dwarf the size of the Earth, continuing to shine for billions of years before slowly dying.
However, this is not a crisis that may lead to the destruction of the earth. Shen Bei will not care even if it happens a thousand years later, let alone five billion years later.
According to the information he read from Bermuda, the Earth would be in danger of destruction in just a dozen years or less.
Now, for Lingxi Zhiling, this peculiar distribution of planets in the solar system is very rare in its cognition.
Generally, galaxies are composed of at least two or more stars.
That is to say, there are two stars rotating opposite to each other in a galaxy.
It is extremely rare for the solar system to have only one star and remain stable.
In other galaxies, if one of them dies, it becomes a white dwarf.
This very small but very massive white dwarf will continue to absorb matter from another star, causing the mass of the white dwarf to continue to grow.
When this mass reaches 1.4 times the mass of the sun, the white dwarf will explode violently.
What’s even more interesting is that what came out of the explosion was all iron.
In other words, the large amount of iron suspended in the universe was produced by such explosions.
Lingxi Zhiling also mentioned that if there is intelligent life in this binary star system, it will definitely be more highly developed than life on Earth.
Because the situations these intelligent lives face are more complicated than those faced by Earth.
Simply put, the so-called alien life has to face two suns.
For example, humans find it difficult or poor at solving game problems.
For example, if eleven people play football against each other, it is difficult to analyze who will win because there are 22 uncertain factors.
