Chapter 657 The Speed ​​of the Universe
Bailixiu waved goodbye to Kai, entered the Kunpeng, and then left with the United Caravan's convoy.

Bailixiu sat in the cockpit of the Kunpeng and watched the energy storage indicator on the Kunpeng slowly rising. She was also happy after all, because once the energy of the Kunpeng was almost collected, she could fly to the King's Continent. expedition to the moon.

See if the mark on the moon that was suspected to be a spaceship fell to the ground. At this time, Bailixiu turned his attention to the Kunpeng, and the attribute panel of the Kunpeng was also displayed in front of Bailixiu.

Equipment name: Kunpeng
Equipment level: King

Equipment features: light energy absorption, light energy engine, laser cannon.

Equipment evaluation: completely separated from the traditional fuel energy, using light energy as the driving energy, as long as there is light, there is no need to worry about energy issues anymore.

The attribute panel of the Kunpeng has not changed and is still the same. However, Bailixiu already knew when using it in the One Piece world that although the Kunpeng has the function of absorbing light energy, it does not need to add any fuel, it only needs to bask in the sun. It's time to fly.

But it is quite tricky. The light energy absorbed by the sun for an hour only accounts for [-] ten thousandths of its total capacity.

You know, the light energy absorbed by the Kunpeng in real time has reached 250 kilowatts per hour. Therefore, Bailixiu naturally knows that his Kunpeng can store 100 million kilowatt hours of electricity when the light energy storage is full.

However, judging from the fact that it can only absorb 250 yuan of electricity through light energy in one hour, even if it can be illuminated for ten hours a day, it will take four hundred days and days to fully charge it.

This is also why Bailixiu's Kunpeng has almost never appeared in the world of One Piece. It was only used against Uranus, the King of Im, at the end.

There is no way who could make the Kunpeng's light charging speed extremely slow!
Bailixiu also has a huge headache about this problem, and the spacecraft consumes the most when it escapes from the gravity of the planet. After all, it is not easy to accelerate to the second cosmic speed.

As for cosmic speed, it refers to the minimum speed required to launch artificial Blue Star satellites, interplanetary and interstellar vehicles from the Blue Star surface into space.

It is known that the speed of the first universe of Blue Star is 7.9 kilometers/second, the speed of the second universe is 11.2 kilometers/second, and the speed of the third universe is 16.7 kilometers/second.

Of course, the first, second, and even third cosmic speeds are not absolute, and will vary depending on the mass of the planet and the star system where it is located.This first cosmic velocity is the speed at which objects move in a circle close to the surface of the blue star.It is also the minimum launch speed and maximum rotation speed of the artificial Blue Star satellite.According to mechanical theory, v1=7.9 km/s.In fact, there is a dense atmosphere on the surface of the blue star, so it is impossible for the spacecraft to move in a circle close to the surface of the blue star.It must fly at an altitude of 150 kilometers to circle the Blue Star.When the spacecraft is operating at an altitude of hundreds of kilometers above the ground, Blue Star's gravity on the spacecraft is smaller than when it is on the ground, so its speed is also slightly smaller than v1. The orbital speed at this altitude is 7.8 kilometers/second.

The second cosmic velocity is the escape velocity, also known as the second cosmic velocity, which refers to the minimum speed required for an artificial celestial body to escape the gravitational grip of a blue star without power.If air resistance is not included, its value is 11.2 km/s, that is, √ is twice the speed of the first universe.When an object or spacecraft reaches 2 kilometers/second, it can break away from the gravitational pull of the Blue Star, fly away from the Blue Star and enter an orbit around the sun, and no longer orbit the Blue Star.If a star is very massive, its gravity will be very strong and its escape velocity will be very fast.Conversely, a lighter planet would have a smaller escape velocity.The escape velocity also depends on the distance between the object and the center of the planet.The closer the distance, the faster the escape.

The third cosmic speed is the lowest initial speed at which the universe takes off from the blue star and leaves the solar system.If an object on the surface of a blue star wants to escape the constraints of the sun's gravity and fly to space outside the solar system, its initial speed must be greater than or equal to 16.7 kilometers/second, which is the third cosmic speed.It should be noted that this is the v3 value calculated when the tangent direction of the spacecraft's orbital velocity is consistent with the blue star's revolution speed; if the direction is inconsistent, the required speed will be greater than 16.7 km/s.It can be said that the speed of the spacecraft is the only factor that can escape the gravity of the blue star or even the sun.Today, rockets can break through cosmic speeds.

The fourth cosmic speed is when the spacecraft begins to escape the gravitational constraints of the Milky Way.After the invention of the spaceship, humans from Blue Star began to increase their speed.The three proposed cosmic velocities have been completed.It reached the first cosmic speed in 7.9, the second cosmic speed in 11.2, and the third cosmic speed in 16.7.Among them, the first, second and third cosmic velocities are [-] kilometers/second, [-] kilometers/second and [-] kilometers/second respectively.Since humans know so little about the Milky Way, it is impossible to determine its mass and radius, and it will take a long time to form a public opinion on this number.

The fifth of the six cosmic speeds is the lowest speed at which a spacecraft launched from Blue Star can fly out of the local galaxy cluster.At the state of 21st century science, scientists estimate that the Local Cluster is approximately 500 to 1000 million light-years in diameter.According to this calculation, the flight speed should be 1500-2250 kilometers per second. However, based on the level of scientific development when Bailixiu left Blue Star, it will take at least hundreds of years to reach this speed. Therefore, it cannot be reached in the 21st century.

The sixth cosmic speed of the six cosmic speeds refers to the speed at which a spacecraft is launched from the blue star to escape the gravitational pull of this supercluster of galaxies.The diameter of this supercluster is approximately 1 million to 2 million light-years.Under the influence of a series of objective conditions such as science, technology and energy consumption, it is theoretically possible to fly away only when approaching the speed of light.Reach the sixth cosmic speed, travel to farther interstellar space, and even reach the edge of the "universe".

Of course, Bailixiu actually doesn't have to consider the last three of the six cosmic speeds. What Bailixiu has to consider now is actually how to make the Kunpeng's light energy absorption speed faster.

If it were absorbed at the current speed, it would have to wait four hundred days, that is, more than a year, before he can start his moon landing plan.

And Bailixiu doesn't want to spend such a long time. Even if conditions permit, Bailixiu wants to explore the moon now, but there is no way. Judging from Bailixiu's experience in space in the world of One Piece, she wants to To land on the moon, the energy reserve of Kunpeng must be increased to more than 90.00%.

After all, it takes a lot of energy to accelerate such a large Kunpeng to the second cosmic speed. One million kilowatt-hours of electricity may seem like a lot, but in fact it is not much.

After all, one kilowatt hour of electricity is only 360 million joules if converted into joules, while the energy of a kilogram of TNT explosion can reach 410 million joules.
