I met unscrupulous teammates at the beginning, watch me turn the tide

But for the intelligent life produced by this binary star system, it is very simple for them to analyze it.

Lingxi Zhiling also made a joke that if the football of the old era was brought to other intelligent galaxies, they would definitely develop into three or four teams playing together.

In addition, here are some tips for measuring space distance, how humans can determine how far a galaxy is from the earth.

The usual practice is to find a white dwarf in the galaxy and calculate it by looking at its brightness.

Lingxi Zhiling also suggested giving it a try, but Shen Bei refused, saying it was easy and a waste of cell lines.

Back to supernova explosions, a supernova explosion will only occur if the mass is more than six times that of the sun.

A lot of knowledge has been laid in the previous part.

Lingxi Zhiling then gets to the point.

Somewhere far away from Earth, a star is exploding.

This star can even be seen by looking up at the sky.

It is Betelgeuse in the constellation Orion.

This star is so huge that its radius is as far as the distance from the sun to Jupiter.

Its mass is more than twenty times that of the Sun.

According to the knowledge described above, the smaller the mass of a star, the longer its lifespan, and the larger its mass, the shorter its lifespan.

The lifespan of Betelgeuse is as short as only 10 million years.

According to Lingxi Zhiling's calculations, at this moment, this year, Betelgeuse's lifespan has reached its end after 10 million years.

So, it is going through the critical moment of the Big Bang.

Measurements and analysis show that Betelgeuse's brightness is increasing, has reached a critical point, and is suddenly beginning to dim.

Photos taken by Lingxi Zhiling show that the current brightness is less than half of what it was about two months ago.

And Betelgeuse is in the process of exploding.

It expands and then contracts.

When it shrinks to the extreme, it begins to explode.

During the contraction process, the atoms in the center are flattened, the electrons are squeezed into the nucleus, and then the protons will become neutrons. Therefore, there is nothing in the center except neutrons. It will eventually form a small planet with a diameter of only about 20 kilometers, and then begin to explode, ejecting everything on the periphery.

Then there will be a pure neutron object left in the middle, which is a neutron star.

Neutron stars are different from other planets. Other planets at least have sand and stones, but neutron stars are covered with neutrons.

Every cubic centimeter of a neutron star weighs billions of tons.

At the same time, the two poles of the neutron star will emit high-intensity electromagnetic waves.

Some of these electromagnetic waves are visible light, and neutron stars also rotate at high speed.

Therefore, during this rotation process, if the electromagnetic waves emitted by the two stages of the neutron star hit the earth.

This neutron star can be seen flashing in the sky, so this neutron star has another name "pulsar".

But pulsars' rotation is very stable and can last for tens of billions of years.

Here, pulsars have another function, which is to calculate time.

However, when traveling in space, the flight speed is uncertain and the flow of time will also deviate.

Then the task of unifying time falls to pulsars.

Back to the topic, the scary fact is that Betelgeuse is only 600 light-years away from Earth.

When it explodes, it releases a large amount of nuclear radiation, that is, gamma rays.

If this gamma ray is facing the earth at the beginning of its explosion, the earth's ozone layer will be cleared instantly.

At the same time, the last scene visible on Earth is white.

Nothing can be seen except white.

Everything will die in an instant.

In other words, when Betelgeuse exploded, its two poles did not hit the Earth, and the Earth escaped the disaster.

According to Lingxi Zhiling's deduction, the dinosaurs of that time might have witnessed other neutron stars exploding and irradiating the earth with two poles.

Currently, Betelgeuse is experiencing an explosion, but it is currently impossible to infer or calculate whether the two poles are aimed at the Earth.

The only contingency plan is... to temporarily leave the earth and wait for the results.

What Shen Bei is currently doing coincides with what You Wuchang is doing.

The difference is that Shen Bei controls it himself, while You Wuchang relies on Ling...
