Hand rubbing nuclear fusion live in the wilderness

Chapter 475 Magnetic field antigravity engine

One stone caused a thousand waves, and when Han Yuan's words came out, the live broadcast room became lively, and the number of people who fell to the bottom and only a few thousand people began to recover rapidly.

[Hey, this is not bad, build a spaceship! 】

[Controllable nuclear fusion miniaturization! 】

[With this, human beings can truly enter space and colonize the moon and Mars! 】

[Upstairs, what limits your imagination?With the courage of human beings, as long as the energy is sufficient, it is not a problem to go to Sirius. 】

[The miniaturization of controllable nuclear fusion is expected. I am even more curious about what kind of engine the gravitational engine is mentioned by the anchor. 】

[Yes, I am also more curious about this, what kind of engine is it? 】

[Here I come, here I come, after 20 days of math, did you finally start doing something else?Am I missing something? 】

[Upstairs you missed something good! 】

In the live broadcast room, following Han Yuan's words, the former excitement resumed.

The miniaturization of controlled nuclear fusion and the spacecraft engine related to gravity blasted not only ordinary spectators, but also experts and officials from various countries.

There is no need to say much about the importance of controllable nuclear fusion miniaturization.

Regardless of the aspect, as long as human beings still need energy, they cannot escape the devices that supply energy.

If the miniaturization can be done thoroughly enough, it is possible to put a controllable nuclear fusion reactor into a car or an airplane.

Not to mention its impact on industries such as aerospace and marine navigation.

If controllable nuclear fusion is miniaturized enough to fit on a space shuttle, the realization of moon and Mars immigration will be tomorrow.

Even if environmental problems make it impossible to immigrate in large numbers, various bases can be established on the moon and Mars, and various minerals on the moon and Mars can be mined.

It can be said that the miniaturization of controllable nuclear fusion is the only way for human beings to go into space.

After all, with the current fossil energy, its propulsion efficiency and utilization efficiency are too low, so low that it is not enough to support various space activities normally.

Take the famous "Saturn V" carrier rocket in history as an example. This product of the era of the Mi and Soviet hegemony in space is the carrier rocket with the strongest carrying capacity in history.

Its maximum carrying load is just over 110 tons, to be precise, [-] tons, but its own weight exceeds [-] tons.

A load of one hundred tons sounds like a lot, but it is really too small compared to its own huge weight and the various materials needed to build a base on an alien planet.

For example, to establish a base on Mars, the first consideration is the safety of the personnel in the base.

Then the materials used must meet certain protection standards.

Because there are Martian storms on Mars, although the atmosphere is relatively weak compared to the earth, the destructive power cannot be ignored.

And no matter what kind of protective material, as long as the word "protective" is worn, its own weight is definitely heavier than the available non-protective material.

Even the commonly used light alloy of titanium-aluminum alloy has a density of 4.54g/cm3.

It's not a problem to use more than a dozen tons of titanium-aluminum alloy for a base, right?

In addition, there are various other building materials, experimental equipment, daily supplies of base personnel and so on.

These things basically have to be transported from the earth.

This is quite a test for the capacity of launch vehicles or space shuttles.

As for the capacity of launch vehicles and space shuttles, there are actually two things.

One is the amount of fuel, and the other is the efficiency of the engine, which is thrust.

Fuel determines how far it can fly, and the thrust provided by the engine determines how much it can carry.

These two key factors determine whether the aerospace industry can thrive.

Han Yuan glanced at the barrage and said with a smile: "Since everyone is looking forward to it so much, I will reveal it in advance."

"Because the mission this time is to explore outer space, and I plan to go to the moon and build a base on it, the thrust provided by conventional fossil fuel engines and electric propulsion engines is a bit small."

"And this time the engine used on the new spacecraft is named 'magnetic field anti-gravity engine'."

"Compared with conventional fossil fuel engines and electric propulsion engines, the magnetic field antigravity engine is more efficient in the application of energy and can also provide greater thrust."

"But at the same time, it also consumes a lot more energy."

"So it is generally used with a device that can provide a huge amount of energy, such as a controllable nuclear fusion reactor."

"In addition to consuming energy, this magnetic field anti-gravity engine has some disadvantages."

Before Han Yuan finished speaking, the live broadcast room exploded.

[I'm sorry, I heard that right, right?Anti-gravity engine. 】

[Hiss~, Hearing this, I take a deep breath! 】

[Suck together, suck together! 】

[Did I hear wrong, anti-gravity engine?Is this something that can emerge at this stage? 】

[Didn't the anti-gravity engine be an IQ tax? 】

[Yes, what about those people who said that the anti-gravity engine is an IQ tax?Why is this silent? 】

[The anchor's slap in the face is wonderful. 】

[Magnetic field anti-gravity engine, magnetic field!magnetic field!magnetic field!Are you patronizing the three words anti-gravity? 】

[Gravity is gravity, isn’t this anti-gravity engine an anti-gravity engine? 】

[Anti-gravity and magnetic field anti-gravity are two completely different concepts, okay?Gravity is produced by gravitation, and its size is equal to the mass of the object multiplied by the acceleration of gravity g, that is, G=mg. 】

[The so-called anti-gravity is actually to give the object a force outside the ground. When it is opposite to gravity, the person can be in a suspended state. Let alone this anchor, we have many technologies that can achieve this, such as Maglev train or something. 】

[I guess the anchor is using this technique, right?Only it could be better. 】

[No, no, there are rails under the maglev train. There is a magnetic field between the rails and the maglev train. This magnetic field can support the train, but how does the spaceship carry the rails? It has a p, so it must be different from the maglev train. 】

[Can this thing be used in a car?I seem to buy a car that can fly! ! ! ! 】

[Nimma, isn't that the kind of anti-gravity car in the movie?Love love love! 】

When they heard the magnetic field anti-gravity engine, the audience in the live broadcast room instantly split apart, and all kinds of bullet screens were dense like a storm, constantly brushing across the virtual screen.

The three words "anti-gravity" seem to have a magical power, making the audience in the live broadcast room directly become all kinds of popular science monsters, constantly brushing things related to gravity and gravitation.

It's a pity that Won, who watched these bullet screens, shook his head. Most of the audience in the live broadcast room didn't even understand the relationship between magnetic field, gravity, and gravity, so how could they understand the anti-gravity engine he talked about.

Shaking his head, Han Yuan said, "If you want to understand the magnetic field anti-gravity engine I'm talking about, you need to understand the concepts of magnetic field, gravity, and gravitation."

"I will not explain the magnetic field. This concept has been mentioned many times before."

"And gravity and gravitational force are more critical things."

"First of all, gravity and gravity are not the same thing. Gravity is a branch of gravity, but it is not the same as gravity."

"Gravity is largely derived from gravitation, but it's not all gravitation."

"In terms of definition, gravity is within the scope of statics, with the support on which the object is placed or the object itself as the non-inertial reference system, the resultant force of the gravitational forces and the inertial forces on the object."

"As for the gravity in your mouth, it is the gravity version of the long-ago definition. It can only be regarded as a special branch definition of gravity, which can be established under certain special circumstances."

"And the magnetic field anti-gravity engine I'm talking about is something based on a new definition."

"Its principle is similar to that of the maglev train, except that the maglev train generates a floating magnetic field between the train and the rails, while the magnetic field anti-gravity engine eliminates the concept of rails."

"In other words, it uses a planet that can generate gravity like the earth as a rail track, and generates a corresponding repulsion to reduce its weight until it reaches zero and finally floats."

"To understand this concept, you need to understand the new concept of gravity in my mouth to a certain extent, but this should not be difficult."

After a pause, Han Yuan continued, "As for the anti-gravity engine you mentioned, it's actually quite a high-level concept."

"Gravity is one of the four fundamental forces, but it is also the most mysterious and universal force in nature."

"Generally speaking, there are two sources of gravity."

"The first is that gravity is derived from particles, and the second is that it is derived from curved space-time. Both statements have their own characteristics."

"Of course, in addition to these two sources, concepts such as quantum gravity, loop quantum gravity theory, and the acoustic analogy model can also explain gravity to a certain extent."

"If you follow the first two sources of gravity, the gravitational engine you are talking about is an engine that can fly faster than the speed of light."

"The magnetic field anti-gravity engine I made today is far from reaching this point."

Korean Won briefly explained the 'magnetic field anti-gravity engine', but not much was understood in the live broadcast room.

[Using the earth as a guide?Create another magnetic field to prop up the ship? 】

[Why does it sound like I'm stepping on my left foot and stepping on my right foot to go to the sky? 】

[On the top floor, I also have the same feeling. 】

[Demoted upstairs, with such a low IQ, I can't understand this. 】

【? ? ? ? ? 】

[I'm thinking about how this thing can make the plane fly. According to the anchor, this thing can at most reduce the weight of the spaceship to zero and float it, right? 】

【fool!Wouldn't it be nice to make another engine to provide power? 】

[Fuck, I thought of a terrifying thing. This magnetic field anti-gravity engine can reduce the weight of the spacecraft until it reaches zero, not to mention that this thing can reach the speed of light? 】

【Eh? 】

[It seems to be the reason?I remember learning in high school that objects with weight cannot reach the speed of light, but you didn’t say that objects without weight can’t do it? 】

[I wipe?That being said, this thing is quite scary! 】

In the live broadcast room, the audience was talking about the magnetic field anti-gravity engine, and experts from all over the world were also discussing and thinking, especially the physics experts, staring at the screen with twinkling eyes.

For ordinary people, as long as they come out to work, they probably basically forget the knowledge in their minds.

But for a research specialist, the basics are the last thing to forget.

The definition of gravity has indeed been updated in many versions.

Compared with gravity, the new definition of gravity is established on the premise that gravity and supporting force are in balance.

This general theory is a bit more complicated than the previous simple definition, and it is not as clear to ordinary people as before.

For example, the acceleration of an object is one of the important factors that determine the magnitude and direction of gravity. The gravity of the same object will change greatly due to the change of acceleration.

Another example is that the new version of gravity is the resultant force of gravitational force and inertial force or a component force of universal gravitational force, and the resultant force obtained by the synthesis of forces or the component force obtained by the decomposition of forces are all artificially imagined forces, so gravity It is a virtual force that does not actually exist.

But this point will definitely be sprayed by most ordinary people. If there is no gravity, how can people stand on the ground?
In addition, there are actually many similar points.

If you want a simple explanation, it is roughly that gravity is not only the gravitational force produced by the earth, but also interfered by the supporting force, the gravitational force of the sun, the moon and other stars. If the supporting force is lost, the gravity will disappear.

For example, an empty-shell projectile or a spacecraft artificial satellite with its engine turned off, because the objects inside it cannot get support, so gravity cannot appear, and the objects inside these devices are in a state of complete weightlessness.

But what cannot be ignored is that although gravity disappears, universal gravitation still exists.

Compared with the previous version, the new version of the definition of gravity is indeed not as easy to understand for ordinary people as before.

However, the new version of the definition of gravity is also the basis of the 'magnetic field anti-gravity engine'.

After listening to Won's explanation, physics experts from various countries have roughly understood it.

However, I understand that the theoretical basis is the theoretical basis, but I have no idea how to make this thing.

Although maglev trains are widely used today, maglev trains and 'magnetic field anti-gravity engines' are two completely different things.

To put it bluntly, it is to remove the rails under the maglev train and let it run on the ground out of thin air.

The anti-gravity cars in the movies mentioned by ordinary netizens are actually not much wrong.

But how to do this, for now, experts from various countries basically have no idea. The only thing that can be thought of, like ordinary audiences, is to install a device that can provide a strong magnetic field at the bottom of the spacecraft.

But how this device will be manufactured and what it will look like has no idea at all.
