Chapter 344 Planetary Collision!
During the process of the No. 43 satellite flying over, the bombardment of Planet No. 1 never stopped.
The human fleet bombed indiscriminately, in all kinds of ways. Energy cannons, laser beams, interstellar missiles, interstellar mines, and especially the most important hydrogen bombs, never stopped.
The topography of this planet has even been completely changed. Mountains were flattened and canyons were filled. The large pits formed by the explosion of hydrogen bombs kept appearing, disappearing again and again in the fierce attack, and then reappearing and disappearing again, and so on.
The less than 400,000 lava beasts left were always hiding underground and refused to come out.
If they were intelligent life enemies, they should have easily noticed the abnormality of humans at this moment.
After all, it was strange that they still maintained such a long and fierce attack even though they knew that they could not hurt us hiding deep underground.
It was obvious that humans had some conspiracy.
But lava beasts are not intelligent life.
Although they have combat skills, they are ultimately just acting on instinct.
They only know that hiding underground is safe, and the surface is dangerous because of the enemy's bombardment. Once they reach the surface, they will be killed.
So they must hide well, as long as they hide, they will not be killed, and they will go out when the human attack stops.
Time passed slowly, and three years passed in the blink of an eye.
At this moment, the speed of satellite No. 43 relative to planet No. 1 has been accelerated to 102 kilometers per second.
Under the gaze of the huge dark red star, the small planet No. 1 is passing the perihelion and has even entered its outer atmosphere.
If someone stands on planet No. 1, then what will appear in his eyes will be a huge sun that is so huge that it is indescribable.
This sun will occupy three-quarters of the entire celestial sphere, almost covering the entire sky. If you ignore the too dazzling light, the person standing on planet No. 1 can even clearly see the surging plasma on the surface of the YT-621 sun.
The volume of a star at the end of its life is extremely large, with a diameter of more than 30 million kilometers, but its outer atmosphere can even extend to twice that distance.
At perihelion, the planet's orbital speed is the fastest.
At this moment, its speed relative to the star has reached 65 kilometers per second.
The extremely high speed leads to intense friction with the star's outer atmosphere.
No matter how thin the star's atmosphere is at this distance, the friction caused by the high speed has caused the surface temperature of the planet to rise to more than 1,000 degrees Celsius.
This is the side facing away from the star. The temperature is even higher on the side facing the star.
If Planet No. 1 had an atmosphere, the situation would be better, after all, it would not be in direct contact with the star's gas.
But unfortunately, in rounds of reciprocating orbits, the atmosphere of Planet No. 1 has long been stripped away, leaving no residue, so the planet's surface can only come into direct contact and friction with the star's atmosphere.
In this friction, Planet No. 1's own huge momentum is being consumed bit by bit. When the momentum is consumed, the planet will fall a little towards the star, and in this process, the gravitational potential energy of the planet will be converted into kinetic energy, speeding up its speed and preventing it from falling further.
Then, the kinetic energy is consumed again, and the gravitational potential energy is converted into kinetic energy again... and so on.
Until it exceeds a certain critical point, the gravitational potential energy can no longer provide it with more kinetic energy, and it will plunge into the star gas and completely merge with the star.
But this takes too long, even more than 10 million years.
People decided to advance this time.
The way to advance it is satellite No. 43.
At this moment, it is less than 10 million kilometers away from planet No. 1.
When it orbited planet No. 4, it originally had a speed of about 8.5 kilometers per second. As it kept approaching the star, the kinetic energy converted from gravitational potential energy increased its speed by about 16 kilometers per second.
And the work of more than 300,000 planetary thrusters for several years provided it with a speed of about 22.5 kilometers per second.
In total, its speed at this moment has reached about 47 kilometers per second.
Moreover, under the triple influence of the star's gravity, the planet's gravity, and the planetary thrusters, its speed is still accelerating.
It rushed straight to Planet No. 1, unstoppable.
At this moment, the fierce bombardment of the surface of Planet No. 1 is still in progress.
Under the harsh environment around the red giant, the light and heat that are constantly gushing out from the star, and the high-temperature and high-radiation gas, the human fleet still dare not relax at any time.
The plan is now in the final stage, and it must not fail.
The speed of Planet No. 1 is accelerating. The speed of Satellite No. 43 is also accelerating.
In the end, only 20 hours later, the long distance of 10 million kilometers was crossed by the two planets running in both directions. Then, at a slightly tilted angle, Satellite No. 43 slammed into Planet No. 1.
At this moment, the speed of Planet No. 1 relative to the star is 70 kilometers per second. The speed of Satellite No. 43 is 58 kilometers per second.
In a low-speed environment, the total speed can be added directly without considering the influence of relativistic effects. Eliminating the angle problem, the relative speed of the two planets reaches an astonishing 125 kilometers per second.
The human fleet had evacuated in advance and witnessed this shocking collision in a safe place.
At this moment, Satellite 43, which is only 1/160 of the size of Planet 1, almost plunged into Planet 1. At the edge of the collision, endless rocks splashed out, and even broke free from the gravity of the planet and the star and began to fly into interstellar space.
The entire Planet 1 shook violently at this moment. Countless peaks created by hydrogen bombing were directly flattened, countless canyons were directly closed, and countless new canyons emerged directly.
On the back of the impact point, a mountain hundreds of kilometers high suddenly emerged.
The whole planet turned upside down.
Through simple calculations, people can know that in this collision, a full 1.5*10^32 joules of energy were released.
This number is so large that it is beyond people's intuitive understanding.
The total energy of solar radiation received by the earth per second is about 1.74*10^17 joules.
These energies drive the movement of the earth's atmosphere, form wind, rain and lightning, heat the ocean, keep the ocean liquid, evaporate water, form rain and snow, provide warmth for all things, and breed the flourishing of life.
The energy released by this impact is equivalent to 814 times this number.
That is, if the energy released by this impact is converted into the solar energy received by the earth, this energy can illuminate the earth for about 27.3 million years.
The solar energy received by the earth is about 1/2.2 billion of the total solar radiation energy.
In this way, the energy released by this impact is about equivalent to the total energy released by the sun in 4.5 days.
All the energy received by the earth from the sun in 27.3 million years, or all the energy radiated by the sun in 4.5 days, was instantly released in this impact.
Planet No. 1, which had been constantly rubbed by the outer atmosphere of the red giant, and whose orbital altitude was constantly reduced, was suddenly hit so violently at this moment, and was subjected to such a violent energy explosion, that the orbit of the entire planet was significantly affected.
It is still orbiting the red giant, but compared with the previous orbit, its orbit at this moment has obviously dropped a lot, showing a clear arc.
It has lost more speed. Therefore, the laws of physics force it to reduce the orbital altitude more to make up for the loss of speed.
But... the closer to the red giant, the deeper into its atmosphere, the higher the density of its atmospheric material.
The higher the material density, the more intense the friction with the planet. The more intense the friction, the faster its kinetic energy loss, so the orbital altitude is further reduced.
The further reduction in orbital altitude further increases the rate of kinetic energy loss.
This is a vicious cycle that is irreversible once it starts.
The faster you fall towards the star, the faster you fall.
In just three days, the figure of Planet No. 1 was swallowed up by the huge red giant and could no longer be seen from the outside world.
This journey would have taken more than 10 million years to complete, but with the participation of humans, it was completed in just three days.
It fell into the star forever. Along with it fell nearly 400,000 powerful lava beasts hidden deep under the surface, still waiting for the enemy to stop attacking.
People knew very well that although the previous impact was fierce, it would not kill all the lava beasts hidden under the surface of the planet.
But it doesn't matter. After falling into the star, this aging and violent star will kill every lava beast on behalf of humans.
It is impossible for lava beasts to survive in the star. Even if the survival ability of lava beasts is increased tenfold, it is impossible.
The fate that awaits them will be to be torn apart together with Planet 1 after crossing the Roche limit, and then completely swallowed.
——For some stars with extremely low density, the Roche limit can even enter the interior of the star. Obviously, this red giant is such a star. So even if it was swallowed, Planet 1 was not torn apart, but only after it went deeper.
The fall of Planet 1 triggered a more violent reaction of the red giant, making it more violent.
More stellar matter was ejected, and the galaxy environment became more severe.
But it doesn't matter, the human fleet has already hidden in a safe place.
After watching the entire process of the planetary collision, Lu Xinghe knew that the human side had truly completed this mission.
Although there are still a few fish that have slipped through the net and hidden in the galaxy, they can no longer make waves.
Their only fate is to be searched out and destroyed by the human fleet. (End of this chapter)
