Is it true that gravity can slow down time? Why is time slowing down?

In the general theory of relativity.

Gravity can indeed slow down the flow of time; Because of the curvature of space-time.

It affects the state of existence of space-time, so gravity also has the magical effect of changing time. We all know that time and space can be said to be the biggest issue that we have been tirelessly exploring in the fields of philosophy, science, and theology since the birth of mankind for tens of thousands of years.

It can be said that once the mystery of time and space is completely solved by us, then human beings have officially found the "ultimate mystery"; After that, I am afraid that all scientific problems will be solved by us. After all, when the time comes, the observable universe.

Nothing can stand in the way of humanity anymore.

There are also endless assumptions about time. I'm sure many of you have heard the idea that gravity can slow down time.

Sounds like a lot of ""; So, does it make sense? It can be responsibly said that in modern physics, it is indeed true.

That's right, gravity and gravity are the keys to changing time and space.

One. In the last century the great physicist Albert Einstein.

In the proposed system of general relativity, gravity has the effect of "bending" space-time.

In other words, it is gravity that causes space-time to change; However, various changes in space-time will also cause corresponding fluctuations in gravitational attraction. This wave is what we call a "gravitational wave."

When the steady state of time and space is affected by us, gravitational waves will come into being.

The slowing down of space-time, in Einstein's words, is the so-called "curvature of space-time" numerical change. For example, the Schwarzschild black hole we are familiar with is thought to be a point at which the curvature of space-time expands to near stagnation.

Stephen Hawking.

It is believed that when humans or other beings approach a black hole, the space-time in which it is located will be close to "stationary". The curvature of space-time of a black hole is actually due to the singularity inside its accretion disk, which has an almost immeasurable gravitational force.

In general relativity, gravity does cause the flow of time to slow down. Because the curvature of space-time affects the state of existence of space-time, gravity also has the magical effect of changing time. We all know that time and space are the greatest issues that mankind has been tirelessly exploring in the fields of philosophy, science and theology since its inception for tens of thousands of years.

I don't think so, time is defined by human beings themselves, and it doesn't change because of anything that makes time faster or slower.

Gravity does not change with time. So there's no such thing as gravity slowing down and getting worse. Gravity is only related to the position of the object in space.

The relationship between black holes and time According to Einstein's theory of relativity, gravity slows down time. So when we approach a black hole, time does slow down due to the strong gravitational effect, and it is even possible that when we get close to a certain range of the black hole, 100 years have passed by the time a second has passed. It is difficult (but still possible) to measure the effect of gravity on time if the clock is placed in a place where gravity is weak (such as the Earth).

However, if the clock is placed in a place where gravity is strong, such as a black hole, the effect of gravity on time can be seen immediately, and the magnitude of the effect varies depending on the position of the observer. For a space traveler who falls into a black hole, increased gravity speeds up his perception of things; He will feel that he has been sucked into a black hole and all at once he is at the bottomBut for an observer who is far away and unaffected by a black hole, the opposite is true.

To them, the unfortunate astronaut seemed to move very slowly, and as if the closer he got to the black hole, the slower he moved. The reason is that, according to the theory of relativity, the strong gravity of a black hole slows down time, so it seems that the astronaut never fell to the bottom. At the very bottom, all the mass and energy is condensed into tiny points, and space disappears, and time stops.

All the laws of physics that apply to the outside world in a black hole have come to an end, so we have no way of knowing what the situation is like inside a black hole. There is a scientist Schwarzschild who calculates a range of time and various physical phenomena within the range that are different from the outside, such as: time is slower, gravity is greater.

Because it is calculated by Schwarzschild, it is called the Schwarzschild radius interface, also known as the ground plane. The ground level refers to the state in which the time inside the black hole is completely different from the outside world, because the light is pulled by gravity, the time in the black hole for one minute may be equal to the outside world for decades, for example, if you are sucked into the black hole now, you will be squeezed and crushed after a minute inside, but maybe in a few seconds you see other people who are also sucked into the black hole, but this is actually inhaled decades later.

Let's start with Einstein's theory of relativity.

The theory of relativity is a basic theory about space-time and gravity, mainly founded by Albert Einstein, and is divided into special relativity and general relativity according to the different objects of study. The basic assumption of relativity is the principle of relativity, that is, the laws of physics have nothing to do with the choice of frame of reference.

The difference between special relativity and general relativity is that the former deals with the laws of physics between frames of reference (inertial frame of reference) that move in a uniform linear manner, while the latter generalizes to frames of reference with acceleration (non-inertial frames) and is widely used in gravitational fields under the assumption of the principle of equivalence. The theory of relativity has greatly changed mankind's "common-sense" concept of the universe and nature, and has put forward new concepts such as "simultaneous relativity", "four-dimensional space-time", and "curved space-time". It developed Newtonian mechanics and propelled physics to a new level.

The principle of special relativity is the two basic assumptions of the theory of relativity, and under the observation of the current experiments, the motion of objects is in good agreement with the theory of relativity, so it is generally believed that the theory of relativity is the correct theory.

According to the special theory of relativity, the ruler of motion will shorten and the moving clock will slow down, which is the effect of the "ruler clock slow" of the special theory of relativity. The slow clock means that when you measure a distance, such as the distance from the Earth to the Moon, the distance between the Earth and the Moon is L when you are stationary, and the distance measured when you fly from the Earth to the Moon at high speed when you drive a spacecraft will be less than L, and the higher the speed, the shorter the distance between the Earth and the Moon will be, and the shorter the time it takes.

There is a basic principle of special relativity called the principle of relativity, which means that the laws of physics have the same expression in all inertial frames. Einstein did not stop at the special theory of relativity, because there are inertial frames and non-inertial frames in physics, and special relativity does not penetrate deep into non-inertial frames. In 1911, when Einstein thought further, he had the "most valuable idea of his life", which was that a person would not feel gravity when doing a free fall.

In 1915, Einstein gave the "equivalence principle" on this basis, that is, the gravitational field is equivalent to a reference frame moving with appropriate acceleration. If an object in the gravitational field chooses a suitable frame of reference, it will not have a gravitational term in its equation of motion. In this way, the principle of relativity of special relativity can be generalized to all reference frames, that is, the laws of physics have the same expression in all reference frames.

On this basis, Einstein gave the general theory of relativity.

One conclusion of general relativity is that time slows down in the gravitational field. The reason for slowing down can be easily understood from the following perspective: high-speed motion slows down time, and the acceleration of objects by a strong gravitational field can also slow down time.

For example, the gravitational field near the ground is stronger than the gravitational field in the orbit of a geosynchronous satellite, which means that time passes on the ground and in the orbit of a geosynchronous satellite. It's just that the gravitational ratio of the earth is small, and this difference is generally not noticed.

In fact, today's earth satellites often have to modify time according to the theory of relativity, for example, GPS satellites at an altitude of 20,000 kilometers above the earth are flying at high speed at a speed of 10,000 kilometers per hour. The clock of motion according to the special theory of relativity slows down, it slows down by 7 microseconds per day; According to the general theory of relativity, in a weak gravitational field 20,000 kilometers above the ground, the satellite will be 45 microseconds faster per day. If this is not corrected, it will limit the accuracy of navigation.

If you are near a strong gravitational field, the gravitational slowdown of time will be very obvious. A typical example is a black hole, there is a strong gravitational attraction near the black hole, if an astronaut unfortunately falls into the interior of the event horizon of the black hole, the strong gravitational pull of the black hole will make people on Earth feel that the astronaut's time becomes extremely slow, even after hundreds of millions of years, it will not fall into the event horizon of the black hole, as if fixed at the event horizon of the black hole. And in the eyes of the astronaut, his time has not slowed down, and he is ready to crash into the singularity inside the black hole.

Some science fiction films often use the slow down of time near black holes for various fantasies, and the theory behind it is that the strong gravitational pull of general relativity will slow down time.

Because the gravitational force is so powerful. It can even affect the time when there is no quality. So it can directly slow down time.

The gravitational field has a refractive index function, and everything in the gravitational field moves slower, but local time is not real time, because real time is a large system parameter.

Personally, I think it's because of gravity that time is affected, because gravity is like a big magnetic field, so it controls time and gradually slows down.

The reason for the occurrence of gravitational force (brief description): When the high-energy particles moving in the universe pass through matter (celestial bodies or particles), part of them are intercepted and absorbed to form a weak energy region (Einstein's space-time curvature), which is the gravitational range mv2=e=mv2 (the formula of the law of conservation of energy conversion). For more details, please see the forthcoming gravitational hypothesis, "Elemental Periods and the Causes of Gravitation".

Because gravity can distort space, causing space to fold or elongate, it will cause time to slow down. This is just my personal opinion, and we should still believe what the scientists say.

It is energy that controls gravity and time, and gravity and time are generated by energy. Decisions and controls. The greater the energy of the object (black hole), the greater the mass lost by the object (black hole), and the amount of energy is proportional to the loss of mass.

Time never changes. It's not time that's slowing down, it's the table. Looking horizontally into a ridge, it becomes a peak, and the distance and height are different. Everything is different in the air at any time.

Time does not exist, what changes is space! A year is one revolution of the earth, and the earth's space has changed! Is the sun rising in the east and setting in the west, or is the distance traveled by the earth changing!

Since we are all made of atoms, the electrons in the atoms will change their trajectories with different spatial changes, so the accuracy of our instruments for measuring time will also change! Time and temperature are actually very similar, the environment changes, the temperature changes, the space changes, the distant trajectory of electrons in the atom changes, and time changes! The difference between temperature and time is that temperature changes in both directions, and time changes in one direction!

Because your concept of time has been replaced, I don't say anything about whether that person is Einstein or not.

Atoms have time wave frequencies, fast and slow wave frequencies under different gravitational conditions, and atoms will contract under strong gravitational conditions. Photon time is relatively neither slow nor fast.

How do you know if time is fast or slow? If you don't know, then how can you determine that the time has slowed down and become faster? Why?

Gravity can slow down time, but gravity does not mean that time slows down, but that the effect of time on the object becomes smaller, and it is not nothing, but it is only that the material changes inside the object are slowed down by the influence of gravity. This object will be affected by gravity, and it will also be affected by temperatureIt's all the end result, so that time has less of an impact on him. <>

Any object in the existing universe is affected by gravity, space is almost a weightless state, but almost ten is not completely absent, for example, on the moon its gravitational force is much smaller than the earth, the difference is more than the earth's 1 6, which means that you can jump 50 centimeters on the earth with a light jump, and you can easily jump to three meters high on the moonBut there is still gravity, and the greater the gravitational force, the greater the pressure on the activity of the organism, which is a good thing for the organism to some extent. <>

Because the creature itself is affected by gravity the smaller, it means that the more intense the activity of the molecular atoms in its body, the more it moves in its own free way, that is, in the case of a relatively large gravity environment, the molecular atoms inside the body will be impressed, from the perspective of human longevity, the speed of activity decreases, the speed of human aging will decrease, and the life span of the human body will be extended. The effect on the interior of an organism is actually somewhat similar to the temperature, the lower the temperatureThe slower the activity of the molecules and atoms inside the object, the less time will play on it. <>

If there is a creature that can survive in that place, its own life span will be longer, and its concept of time is absolutely different from that of people on the earth, because gravity will affect time, and time will affect living thingsIn our eyes, 100 years is a long time, and in their eyes, 100 years may be just a meal time, because the concept of planning is different.
