You know, there is no precise definition of the edge of the solar system.

We all know that there are eight planets in the solar system, the farthest from the sun is Neptune, outside Neptune is the dwarf planet Pluto, the Earth is about 6 billion kilometers away from Pluto, and it takes 5.6 hours to travel at the speed of light!

But Pluto is not the edge of the solar system, because in principle, the sphere of influence of solar energy belongs to the solar system! In the vicinity of Pluto is the very extensive Kuiper Belt, and beyond that is the even more extensive Oort Cloud!

The Oort cloud is a spherical cloud that hypothetically surrounds the solar system, covered with many inactive comets, about 50,000~100,000 astronomical units from the sun, and the maximum radius is almost 1 light year, that is, a quarter of the distance between the sun and Proxima Centauri. Astronomers generally believe that the Oort cloud is the remnant of the nebula that formed the Sun and its planets 5 billion years ago and surrounds the solar system.

Voyager 1 has been flying for more than 40 years and has not yet flown out of the solar system, scientists speculate that it is still flying in the Oort cloud, and the Oort cloud is so wide that it would take Voyager 1 tens of thousands of years to fly out of the Oort cloud!

The edge of the Oort cloud is also considered to be the edge of the solar system, which is about a light-year away from the Earth, and the edge of the solar system is called the "heliosphere", which is where the gravitational pull of the solar system balances with the gravitational pull of exocelestial bodies, and it is also the farthest place that the solar wind can reach!

With the current human technology, it is unrealistic to leave the solar system, and it is possible to fly out of the solar system only if it is possible to fly at sub-light speed, which requires a qualitative change in power propulsion technology!

So the spaceship in Ye Fan's billions of technology crystallization system, does he have the speed of light?

Not really.

If you want to leave the solar system, you must have the ability to speed of light to leave.

And this alone is enough to make countless people despair.

The speed of light is the speed of light, which is a phrase not a unit! ms is a unit of velocity, and a light year is a unit of length.

And how fast is the speed of light?

The speed of light is constant, and nothing beats the speed of light. However, this statement is not entirely accurate. The real implication is that it is impossible for any matter that carries information and energy to exceed the speed of light in a vacuum. The speed of light in a vacuum is 299,792,458 m-seconds, which is in fact artificially defined without any error.

The fastest speed of human beings today is nothing more than Mach.

The whole conference room was noisy, very lively, and the views that Ye Fan brought to them really shocked them.

Whether it's the sun, or the dungeon, it's a huge project.

How is it possible to build countless dungeons that can survive in thirty years, or twenty years, ten years?

Isn't that nonsense?

If it is built according to the scale of Ye Fan's blueprint, it will take at least nearly a hundred years for human beings to do it, right?

Even if it's fifty years.

Fifty years is enough for more than half of humanity to survive.

You don't have to have to be able to access a dungeon.

The crowd boiled.

But Ye Fan closed his eyes tightly and began to look for ways to save the sun in the list of billions of scientific and technological crystals.

Super suction diamond drill bit: The principle of suction chip removal is to press pressure cutting fluid from the outside of the cutter into the cutting zone and use the suction method to remove chips internally. The arrangement of the teeth of the suction drill is conducive to chip separation. The cutting fluid flows into the connecting sleeve from the liquid inlet, and one-third of it is sprayed through the crescent-shaped nozzle around the inner tube, and the inner tube is sprayed and suction drilled. Due to the narrow gap between the sockets, the ejection effect generated when the cutting fluid is ejected can create a negative pressure zone in the inner tube. The other two-thirds of the cutting fluid flows into the cutting zone through the inner tube and the outer tube, and the chips are sucked into the inner tube by negative pressure and quickly discharged backwards, enhancing the chip removal effect.

Super jet diamond drill bits are diamonds, but not natural diamonds. Instead, the instantaneous static ultra-high pressure and high temperature technology, or the dynamic ultra-high pressure high temperature technology, or a hybrid of the two, make graphite and other carbonaceous raw materials directly convert from a solid or molten state to diamond, and the diamond obtained by this method is a micron-sized polycrystalline powder. Synthetic polycrystalline powders can be used to form synthetic diamonds for industrial use.

Drill bit?

When Ye Fan saw this drill bit, the corners of his eyes twitched slightly.

Sure enough, the second plan is useful, and if I want to build a dungeon, I directly sent a super drill bit, looking at this detailed data, this drill bit can dig down to a depth of at least 300 meters per hour.

These 300 meters are already the top drill bits in the world, and the size of the drill bits is about 30 square meters in radius.

Other words.

When a drill digs to the desired depth, it is completely possible to build a drill bit underneath for a big expansion!

What about once it collapses?

The collapse problem, Ye Fan has already thought about it, suction and spray the drill bit, you can add H agent into the drill bit, dig all the way, spray H agent all the way.

The H potion is a technology that Ye Fan once exchanged, and it is applied to the construction unit, with this potion, the walls, concrete, and soil layers can be completely stabilized, which is several times that of before.

With these two, at least in terms of excavation, there is a very rapid speed.

Ye Fan looked towards the second unit.

Energy converter: It can refine white crystal and release a large amount of energy. Each white crystal is equivalent to the annual electricity consumption of a first-tier city.

Fame is worth 1,000,000!

White Crystal.

This is something.

One can cover the electricity consumption of a first-tier city for a year, isn't this a bit too exaggerated?

What energy source, with such a powerful energy source?

And the price of this exchanger is also very expensive, worth a million.

Looking at the price, you can know that this is a good thing, but what about Baijing?

Could it be that there is still a technology to make white crystal?

Ye Fan looked down.

Super ion engine: The ion engine is one of the three types of solar electric rocket engines, so it is also called solar electric rockets. Solar electric rockets are a new technology in development and belong to unconventional propulsion systems. It is different from the commonly used chemical rockets such as liquid rockets and solid rockets, which rely on solar energy, not chemical energy. The propellant of a chemical rocket engine converts chemical energy into heat, which is accelerated by the aerodynamic heat of the nozzle and then converted into the kinetic energy of the jet gas stream to generate thrust. The working medium of the solar electric rocket engine is to obtain kinetic energy through the heating of the electric energy converted into solar energy or the action of the electrostatic field and electromagnetic field generated by this electric energy to achieve reaction propulsion.
