Newton's First Law.
The law of inertia is a law that is more contrary to common sense. Since there is no such thing as a completely smooth environment on the earth, any object is kept moving in a straight line at a uniform speed.
It must be maintained by a certain external force. Not affected by external forces will eventually come to rest due to friction, and kinetic energy is converted into internal energy.

Entropy increase theorem. In a closed system, no matter what you do, the entropy increases, which means that the available energy decreases. Counter-common sense, right?
What is even more counterintuitive is that living organisms actually have the ability to partially reduce entropy. The wave-particle duality of light, the momentum, and the zero rest mass. Light, which is basically incomprehensible in common sense, let alone imagining photons or something...

Energy is neither created nor disappears out of thin air, it can only be transformed from one form to another, or from one object to another, and in the process of transformation or transfer, the total amount of energy remains the same. This is the law of conservation of energy, which is widely recognized today. However, matter contains a lot of information before entering the black hole, and after entering the black hole, there are only two pieces of information, mass and energy, and after the black hole disappears, only the information of energy remains, so that the information is not conserved.

Personally, I believe that the world is knowable, and there are laws and theories that can describe the whole world. This is the so-called 'ultimate theory'. But why do all our current laws and theories of physics fail in certain circumstances?
That's because the theories we find now are only valid theories that describe the world, that is, theories that can fit experiments within a very small margin of error under certain conditions, rather than 'ultimate theories' that fit experiments perfectly without conditions and errors. Physics is just asking why there are such experiences, phenomena, and then revealing the laws behind them. Without asking why there are laws, this question should be classified as philosophy or theology, and physics cannot solve it.

Stone sinking in water, why? The stone is in the water, and the water above the stone is less elastic and the water below is more elastic. Because the water above is less elastic when it connects to the air, and the water below is more elastic when it connects to the earth.
After the elasticity of the stone interacts with the elasticity of the upper and lower water, the elastic difference between the stone and the water above it is found to be larger, that is, the repulsion of the water above the stone is greater. Because of the repulsion of the water above on the stone, the stone sinks.

Schrödinger's cat. I believe that many people who have gone to college physics majors can't fully understand this, right? Quantum superposition states or something, the most understanding can't.
General relativity. Mass-energy equation. Mass and energy, in common sense, are two things.
This thing says they're essentially one.

In terms of time, modern physics, which has developed since the end of the nineteenth and early twentieth centuries, can be said to be mostly contrary to common sense. Because the common sense of ordinary people is based on the framework of classical physics, and this only applies to macroscopic and low-velocity situations, matter will exhibit completely different properties in microscopic and high-speed high-energy states.

The theory of kinematic forces of Professor Lei Shaowu at the Faculty of Physics, Federal University of the Galaxy. There is also the fact that electricity and magnetism are not equal in Maxwell's equations, and another physics phenomenon that once puzzled Mach: if a bar magnet is placed parallel to an energized wire, the wire will be deflected.

The observer time difference between the Schwarzschild radius of a black hole. Outside the Schwarzschild radius, the observer sees the slow passage of time within the Schwarzschild radius, while the inside looks outside for a moment of billions of years, how is this done....And space-time distortion, gravity distorts space-time and light, how can this be done....

The ten laws of horror physics are: Newton's first law, Newton's second law, Newton's third law, the law of universal gravitation, the first law of thermodynamics, the law of conservation of momentum, the second law of thermodynamics, the third law of thermodynamics, the law of relativity, and the law of motion limits. These ten laws of physics reveal the true secrets of physics and break the stubborn thinking of people in the past.
1. Newton's first law: There is inertia between objects, and inertia is determined only by the mass of the object.
2. Newton's second law: the relationship between the net force and the acceleration of an object. When the mass of the object is constant, the net force is directly proportional to the acceleration.
3. Newton's third law: the force between objects is mutual, and others will hurt themselves if they hit themselves.
4. Gravitational force: It is formed between all things, not only between planets, but also between people, between any two objects with mass.
5. The first law of thermodynamics: no matter what movement is done, it will follow the conservation of energy, and energy will not be affected in any way.
6. The law of conservation of momentum: It is more universal than the law of conservation of energy. Even if the energy is lost, the momentum is never lost.
7. The Second Law of Thermodynamics: Reveals the Secrets of the Universe. Scientists believe that everything is moving in a more chaotic direction, and that all ordered activities will eventually become disordered movements.
8. The Third Law of Thermodynamics: The concept of absolute zero is introduced by Harmony and Caution, and zero is the absolute zero point in the universe. If the absolute zero point is reached, all motion in the universe will stop, even the irregular motion of molecules.
9. The theory of relativity: proposed by the famous scientist Albert Einstein. The theory of relativity breaks Newton's absolute view of space-time and effectively proves the relationship between the velocity of an object and space-time.
10. The Law of Motion Limit: The photon is the smallest basic unit of energy, and light is the energy in the universe. The speed of light in the universe is constant, it will not be disturbed by other matter, and it will always maintain a constant speed.

1. Mediocrity disturbs itself. This kind of phenomenon is actually a phenomenon that ordinary people can't explain, what UFOs, ghosts, Buddha statues speak, etc., which seem to violate the laws of physics, but in fact, they can be explained. For example, there is a UFO called "flying stick", which is actually a flying insect, and due to the optical principle of the camera, what you see in the video is like a "flying stick".
2. It does not conform to common sense. The phenomena predicted by the laws of physics sometimes do not correspond to people's subjective feelings, such as the Gemini paradox in the special theory of relativity, to say a little more, the meaning of the feint is false, the meaning of the falsehood is false, so the meaning of the paradox is false error, that is, correct, the Gemini paradox predicts a pair of twins in which A returns from an air trip and will find that he is younger than B who stays on Earth. This may seem peculiar, but it is actually required by the laws of physics, and experiments with atomic clocks have confirmed this effect.
3. Caused by human factors. For example, one of the basic principles of the theory of relativity is that the speed of motion of any object is less than or equal to the speed of light. In previous experiments, it was found that the speed of neutrinos was slightly greater than the speed of light, which was a phenomenon that violated the laws of physics, and later it was found that it was caused by errors in the experiment.
4. The theory needs to be improved, and only this can be temporarily called a phenomenon that truly violates the laws of physics, for example, Newton's gravitational theory predicts that Mercury's nearness has an error with the experiment, which violates the laws of physics before the birth of general relativity, but the general theory of relativity has made corrections to Newton's theory and successfully explained the error of Mercury's nearness. Therefore, it can be said that such phenomena are contrary to the laws of physics at the time, and it is expected that they will be explained in the future when more precise theories appear.

Newton's first law (inertia) is a law that is more contrary to common sense.
What Niu Yi said is that the object maintains its original state of motion without being subjected to external forces (either it moves in a straight line at an even speed, or it is not stationary).
Since there is no such thing as a completely smooth environment on Earth, a certain amount of external force must be applied to maintain the uniform linear motion of any object. Not affected by external forces, it will eventually come to rest due to friction. Kinetic energy is converted into internal energy.
