I have overlooked a question. This research and development thing has been protected for a long time, and you are still allowed to go home alone? The family members must have at least three teams taking turns to protect them.

I can only say that it is a model of science fiction written by liberal arts students. It is indeed very enjoyable, if the love ratio is not so high and the pace of slaps in the face can be faster. However, the things in the article really cannot be discussed in detail. First, why does controlled nuclear fusion use nuclear waste? Although nuclear fusion and nuclear fission are both "nuclear", nuclear waste generally refers to uranium, but nuclear fusion uses deuterium and tritium. The second is that controllable nuclear fusion has been researched, but we are still struggling with what to do in the atmosphere. This is not directly related to interstellar battleships (maybe the author does not understand the difference between nuclear fusion and nuclear fission production capacity, but simply thinks it is high-end. To put it simply, the sun has such high energy because of nuclear fission). The third is the section of the airborne pod test. Absolute zero has come out. Brother, the entropy increase has stopped at absolute zero. You have this technology, why bother with a spaceship? Just pause the time (X) In general, it is a cool science and technology article that is more enjoyable to read without your brain, but the prerequisite is that you have to write the emotional scene well. Now the emotional scene is as boring as a primary school student's composition, so it gives people an extremely ink-stained feeling.

If you need to store your brain, you can put it here first Note: This post is not responsible for the loss, shrinkage or theft of brains 🙂

Today's novels just can't escape nuclear fusion. It starts with something and then comes nuclear fusion.

Readers, please stop reading. I'm really begging you. If I didn't read it, I would be a trapeze artist. Please spend a few precious minutes reading it every day. Thank you, Xiaomengxin!

Under the framework of general relativity, the essence of gravity is the geometric effect of a massive object causing the space-time around it to bend. This curvature is described by Einstein's field equations, the mass-energy distribution that determines the metric (i. E., The geometry of space-time). The free motion of objects in curved space-time follows "geodeses" (the longest or shortest paths between two points in space-time), and this motion manifests itself in the gravitational effects we observe. Gravity is not a "force" in the traditional sense, but a manifestation of the inertial motion of objects in curved space-time. The motion of an object is divided into motion in the space-time grid and trajectory in three-dimensional space. Space-time grid motion: In a four-dimensional space-time (three space dimensions + one time dimension) grid, the entire historical trajectory of an object (such as an apple) is a continuous line, called a world line. Without the action of external forces, objects move along geodesics in curved space-time. This geodesic is "straight" (the straightest possible path) in four-dimensional space-time, and it represents the most natural and effortless movement trajectory of an object in the space-time structure. This "straight" is relative to the curved space-time geometry itself. Just like on the surface of the earth (curved two-dimensional space), the flight route along the great circle is a "geodesic" (the shortest path), although it looks like a curve in three-dimensional space. The four-dimensional space-time path is the complete historical trajectory of an object in space and time. Under the action of gravity (without other forces), it is a "straight" line (geodesic) in curved space-time And the three-dimensional space trajectory is the trajectory of the position of an object in three-dimensional space (such as up and down, left and right, front and back) that we usually observe as it changes with time. For example, an apple falling from a tree to the ground will draw a downward parabola (Newtonian perspective) or a more precise curve (relativistic perspective). This three-dimensional path is the result of the projection of the four-dimensional space-time world line into the three-dimensional space. It is the sequence of object positions we see after "cutting" the time dimension. The "curved" falling trajectory (such as a parabola) seen in three-dimensional space is precisely the projection effect caused by the object moving along the "straight" geodesic in the curved four-dimensional space and time. What is curved is not the movement of the object itself (it is a "straight" geodesic in four-dimensional space-time), but the space in which it moves - space-time itself. That is to say, this is actually the trajectory of the object's position in three-dimensional space changing with time. It is the result of a four-dimensional geodesic projected onto a three-dimensional space, and therefore appears curved (like a falling parabola). This curvature is the manifestation of the curvature of space and time in the spatial dimension Imagine an elevator accelerating upward in a weightless space capsule - the hammer feathers will hit the floor at the same time, as if there is gravity pulling downwards. In fact, there is no 'force' at all. The acceleration distorts the space-time grid, causing freely moving objects to hit the floor along the 'straight lines' in the grid. The same goes for the earth's gravity: the mass bends the space-time grid, and the apple rolls toward the center of the earth along a four-dimensional 'straight line', and the 'fall curve' we see in three-dimensional space is just the shadow of this four-dimensional straight line. Gravity itself is not a traditional force. To put it more simply, the essence of gravity is the spherically symmetric space-time curvature effect caused by massive objects. The arrow of the space-time curvature structure points to the center of the massive object. Objects within the range of gravity still move in a straight line in space and time (geodesic) , it's just that the path is distorted. Space-time is moving under relativistic mechanics. Gravity is the geometric effect of space-time Newtonian mechanics regards gravity as the attraction generated by large-mass objects and does not involve space-time. In this system, the movement of objects over time As time goes by, its movement in the space-time grid is a mutually downward parabola. Space-time and the path are flat, and the movement is curved (in this mechanics, it is reasonable for anti-gravity engines to be easy to build, because what you are fighting is only gravity itself) But in In the mechanics of general relativity, gravity is the curvature effect of space-time caused by massive objects. The object moves in a straight line in the space-time grid, but because the space-time points to the center of the massive object, it physically appears to be falling, but the space-time and path are curved. The motion is flat. The same object falls (such as an apple) and is placed in two different mechanical models. Imagine space and time as a piece of paper, one is flat and the other is curved. The flat paper is connected with a parabola from the upper left corner to the lower right corner to represent the time the apple starts from falling to the ground. Path, on curved paper, use a straight line relative to the geometric shape of the curved paper to connect the upper left corner and the lower right corner, representing the movement path. Then roll the two pieces of paper into a straight tube, or a trapezoidal tube with a narrow top and a wide bottom, or an inverted trapezoidal tube with a wide top and a narrow bottom. You will find that the two pass through The path distances are actually approximately equal. Although the path of Newtonian mechanics may become longer in curved space-time, the object falls with acceleration rather than uniform motion, so the farther back it is, the faster it is. In the general theory of relativity, this is because the closer to the bending center, the longer the bending distance. The greater the degree, but the speed of the object itself in the space-time grid does not actually change, so the actual result is that under the same conditions in the two mechanics in the weak gravitational field, the falling path of the same object in the three-dimensional space is actually approximately equal to the inherent length of the four-dimensional space-time. That is to say, the anti-gravity device actually flattens the distorted space-time, that is, bending the space-time in the opposite direction, and it is a single upward distortion, not a spherical symmetrical distortion. This technology is quite difficult, and it involves the structure of space-time. In the same way, artificial gravity also targets the structure of space-time, artificially creating the geometric effect of space-time distortion, and it cannot be spherical symmetry. The direction of distortion must point unilaterally toward the floor. This single distortion is even more difficult! In fact, the anti-gravity device is a variant of the warp engine, because the principle of the warp engine is to manipulate the geometric structure of space and time to achieve faster-than-light navigation! In addition, mankind's current theoretical physics is far beyond the imagination of many people. Humanity's theoretical level has actually gone very far. There have been in-depth theoretical discussions and mathematical models (such as Alcubierre's warp bubble metric) on concepts such as black holes, singularities, cosmic evolution, quantum gravity (string theory, loop theory, etc.), Vacuum energy, and space-time topology (such as wormholes and warp engine theory). However, the scale of the project is not enough to implement the theory. Just give two examples. One is the warp bubble theory based on negative energy. Based on the research and observation of the Casimir effect, negative energy density has been indirectly verified, and nanoscale warp bubble characteristics have also been observed (note that it is the indirectly observed negative energy density, not the negative energy itself, the warp bubble characteristics. ≠Warp Bubble) There is another thing that is theoretically feasible but cannot be verified engineeringly because controllable nuclear fusion has not been broken through. The nuclear fusion pulse engine (Project Daedalus) can reach 12% of the speed of light at the fastest. Calculated at the longest distance, it only takes 5 days to go from Earth to Pluto and back. In other words, ideas such as nuclear fusion pulse engines and nuclear electric propulsion have been around for a long time. There is no need to write about the surprise or confusion of allies. After you can directly put controllable nuclear fusion energy into use, and then launch a large-scale space program, relevant professionals, even with pig brains, can guess what engine you plan to use. (This part uses this engine as a metaphor, referring to similar technological settings in the article that have been theoretically researched but have not yet been implemented. In fact, people can roughly guess what your project is once it is implemented, but they are not clear about your engineering methods, but the principles are clear) Finally, there is the issue of controllable nuclear fusion. The implementation of controllable nuclear fusion does not equal the old energy system. It will collapse immediately. The transformation of the existing system takes time. The reemployment and transformation of workers in the traditional energy industry and the replacement of the existing transportation system cannot be completed overnight. Moreover, oil and coal themselves are important chemical raw materials and will not be simply replaced. The real impact is on the financial system of petrodollars, and the dollar linked to oil transactions is the biggest victim.

The principal's face at the beginning, is he still the principal?

I don't know why, but I just don't like the name rabbit.

Don't pretend that there is no one to protect you. If someone like the protagonist is not protected by thousands of people around him, it would be too poisonous. In a normal world, if the protagonist is a national treasure, as soon as a stranger comes within 3 kilometers of the protagonist, the eighteen generations of ancestors would have already found out, and there is still a chance to run in front of the protagonist 😅. Don't underestimate the country's protective measures.

Leave it first

After reading more than 200 chapters, the protagonist and the country are very awesome. Why doesn't the protagonist come to the front? Always behind the scenes?

Give up your brain, give up your logic, it's still pretty cool

The utilization rate of controllable thermonuclear fusion is really poor. It is not as good as cold nuclear fusion. With this kind of system, it is better to develop space force energy or antimatter baryon compression energy for higher civilizations. Dimensional repulsion energy can reach the sky in one step. Compared with these, the difference between controllable nuclear fusion and these is one yuan and five million 😅

Science fiction is logical and persuasive, but this is fantasy. Please withdraw after reading the first chapter.

If anyone can make any of the equipment in the introduction at this stage, everyone who can come to the meeting in the auditorium should stand up and give this person three bows.

Keep up the good work and update, it has the potential to become a big hit

Understand?

Chapter 1 at 12:00 noon, Chapter 1 at 6:00 pm! Dear readers, I hope everyone knows~~~

There are only a few female protagonists, but why do you feel like there are so many female protagonists?

Exquisite! Understand! ! !

We are only one step away from fusion ignition😭😭😭

Please don't leave any updates or unfinished work. I hope to write more than 14 million words.
