On the question of the view of time and space in modern physics

In fact, so far, there is no definite way to travel through time and space. You can only rely on wormholes.

And wormholes appear randomly anywhere in the universe, so they are not space-time traversed by human forces.

Wormholes, on the other hand, distort space, connecting two places in the universe that are very far apart.

It's like two dots on a piece of paper, as long as they are folded in half, the two dots coincide, and you don't have to walk the distance of one line segment on the paper to reach another point.

Switching to the perspective of space-time is to travel from one space to another in a very, very short period of time. And in ordinary space, it behaves like getting from point A to point B in a very short time. And the speed seems to be very large, even calculated by classical mathematics to be greater than the speed of light.

But in fact, we arrived at point B from distorted space, and the speed did not exceed the speed of light, and did not violate the laws of physics.

But from the average observer's point of view, we "seem" beyond the speed of light, that is, we caught up with and exceeded the arrow of time. The point B we arrive at is the point B of the past, not the point of the future.

It is believed that the technology of controlling time and space travel has not yet appeared, and can only make reasonable speculations from modern physics.

ps, physics is a very fascinating subject, I hope the landlord likes it.

Let's go to the theory of relativity! These are the foundations of quantum physics! In the mysterious Bermuda Triangle, this is often the case, where a long time has passed since the plane and ship sailed in and out again, but the people on the ship or on the plane thought it was just a moment.

The limitation of the relativistic view of space-time and Newtonian mechanics is that the length of a moving object (spatial distance) and the speed of physical processes (time process) are related to the motion of the object. According to Einstein's hypothesis, if two events are simultaneous in one frame of reference, they are not necessarily simultaneous in another.

In different inertial frames of reference, the form of physical laws is the same; The speed of light in a vacuum is the same in different inertial frames of reference (the principle of invariance of the speed of light).

Relativistic view of space-time and the interpretation of Newtonian mechanics:Suppose a person throws a small ball upright, and the motion of the ball follows Newton's laws of motion, and the speed of the plane relative to the ground cannot be judged from this experiment. To determine the relative velocity, you can look through a window at a reference such as a cloud.

With the aircraft as the reference frame, the ball does the vertical upward throwing motion, and the ground is the reference frame, the small ball does the oblique upward throwing motion, and the horizontal partial velocity is the speed of the aircraft relative to the ground. It can be seen that in any frame of reference, the ball follows Newton's second law under the action of gravity and makes a projectile motion.

Newton's view: time and space have nothing to do with space, and space-time has nothing to do with matter and motion.

Quantum mechanics' view: there is no time, and there is no space.

Lao Tzu's view: nothing, the beginning of heaven and earth; Yes, the mother of all things.

The Buddha's view: When we talk about time and space, we are talking about dreams in dreams, and talking about illusions in illusions. Specifically, look at the "Fourteen Questions".

Newton thought so, but this was limited by history.

The space-time view of classical physics encounters some dilemmas in explaining electromagnetic phenomena, the most important of which involve the following two aspects:

Paradoxical particle-wave duality: In classical physics, the view of space-time is based on Newtonian mechanics and Maxwell's equations, describing physical systems as the motion and interaction of particles. However, electromagnetism experiments have demonstrated the wave-like nature of light, contradicting the concept of particles in classical physics.

This results in light exhibiting both particle properties (e.g., photons) and wave properties (e.g., interference and diffraction). The classical view of space-time cannot explain this particle-wave duality at the same time.

The principle of invariance of the speed of light: The view of space-time in classical physics holds that space-time is absolute, and the speed of light should be relative in different frames of reference. However, Maxwell's equations** the speed of light is constant in any frame of reference, which contradicts the classical physics view of space-time.

This dilemma eventually led to the formulation of Einstein's special theory of relativity, which redefined the view of space-time, based on the principle of the invariance of the speed of light, and introduced the concept of space-time curvature.

These dilemmas have prompted scientists to further develop quantum mechanics and relativity to better explain the phenomenon of electrosensitive macromagnetism. Quantum mechanics successfully describes particle-wave duality in the microscopic realm and provides a fundamental theory for electromagnetism. The theory of relativity describes the nature and relativity of space-time more comprehensively, overcoming the limitations of the classical physical view of space-time, thus providing a more accurate explanation of electromagnetic phenomena.

There are three differences between the classical mechanical view of space-time and the relativistic view of space-timeFirst, the views of the two are different:

1. The view of the classical mechanics view of space-time: The classical mechanics view of space-time holds that the measurement of time and space has nothing to do with the state of motion of the inertial frame of reference, and that the kinematics (such as coordinates and velocity) observed by the same object in different inertial frames of reference can be related to each other through the Galilean transformation.

2. The view of relativistic space-time: In the relative space-time view, time and space are linked, they are interrelated and mutually restricted, and the movement of matter has a certain influence on time and space.

Second, the two proposers are different:

1. The proposer of the classical mechanics view of space-time: Newton's absolute view of space-time was proposed by Newton.

2. The proposer of the relativistic view of space-time: The relativistic view of space-time was proposed by Albert Einstein.

3. The essence of the two is different:

1. The essence of the classical mechanics view of space-time: it reflects Newton's absolute view of space-time. The absolute view of time and space holds that time and space are two independent concepts, unrelated to each other, and each has absoluteness.

2. The essence of the relativistic view of space-time: In Einstein's theory of relativity, Newton's absolute view of space-time was denied and a relative view of space-time was proposed. Time and space are closely related, and the movement of time, space and matter are inseparable.

The difference between the view of time and space between special relativity and classical mechanics is that the time process is different, the space is different, and the influence of matter on space and time.

1. The time course is different:

The classical view of space-time has the same velocity of time in any inertial frame of reference; The special theory of relativity views space-time and time that the speed of passage of time is relative.

2. The space is different

The classical view of space-time is flat and even, and the special relativistic view of space-time and space is linked to time, and space-time is uneven.

3. The influence of matter on space and time:

For example, the super gravitational pull of a massive black hole can seriously distort the space-time around it, so that the time process is almost terminated.

It is believed that time, no matter what state it is observed, is unchanging.

It is considered that space, without chanting in what state it is observed, space cannot be changed.

I'll give you a very simple example, and you'll understand. The prerequisite is that the speed of light is equal to c when observed "under any conditions". This is already proven. This is called the "principle of invariance of the speed of light".

You're on the platform of the train station and I'm on the ground of the train.

The train is moving horizontally at high speed.

I emitted light from the ground of the train and hit the top of the car, and there was a small mirror on the roof of the car, and the light reflected back.

My observation on the train: the light goes straight up and down, the distance of the light = 2 times the height of the car, because the speed of light is c at any time and all observations (including your observation and my observation) at any point, so the time it takes to observe this light "I am on the train" is 2t.

Your observation at the station: Because the train moves horizontally at high speed, the light is oblique up and down, and the distance of light is twice the height of the car, because the speed of light at any time is c, so "you are on the station" to observe this beam of light on the train, it takes 2t.

This means that the length of time is different in different frames of inertia. This is demonstrated by the special theory of relativity.

The gravitational formula of classical mechanics. The relationship between m1 and m2 is like the relationship between the earth and the sun. Is the sun suddenly gone, and the Earth immediately out of orbit? It took more than 8 minutes for the Earth to deorbit.

Does gravity really exist, or is it caused by the curvature of space-time.

Time and space in classical mechanics are independent and stationary, while time and space in relativistic theory are unified and relative.

Classical view of space-time: in any inertial frame of reference, the speed of time is the same, space is flat and even, and matter itself does not have an effect on time and space.

Special relativity view of space-time: the speed of time is relative, I am on the earth, and you are moving at the speed of light in a spaceship, so your clock will run slower than that on my earth, but you don't notice it, and you think that time passes normally. But when you compare it with my clock on Earth, you know that your clock is slowing down, you have only been an hour, and I may have been on Earth for a year.

Space and time are linked, space-time is uneven, objects will have an impact on the surrounding space-time, for example, the super gravitational pull of a massive black hole can seriously distort the space-time around it, so that the time process is almost terminated, if you accidentally rub the edge of the black hole in the last second, then you will be sucked in, and your body will be stretched like Lanzhou ramen, but this process will last very long in the eyes of people outside the black hole, that is to say, you may have to die for a year to completely die. But you have to experience it for yourself, and you do die instantly.
