Thinking about a rocket placed on the Earth's surface, it is possible to understand the effects of gravity for long periods of time. After a while, we are going to do it. But it is important to have something to talk about before.
Aristotle thought both Place and Time
Aristotle thought both place and time are absolute. All observers will agree on where and when the event occurred. Newton came and gave a farewell to the idea of the true place. Later on, Einstein came and sent the time to the time. But in the coffin of the absolute time, he just did not have a nail throat. In 1905, the special relativistic theory revealed that it would be relatively slow for the dynamic explorer to move closer to the light. In 1915 he published a theory of more breakthrough. This is the most sophisticated theory of gravitation called the general theory of relativity. However, in the form of a high-speed gravitational, it is possible to prolong the time, in an article published in 1908.Both Principles of Theoretical
Both principles of theoretical doctrine are followed by one basic principle. It is the special theory of relativity that is the basic principle of relativity. It says that the sources of science are the same to all observers who are freely dynamic. Whatever the speed it does not matter. Here's nothing about acceleration. And the fundamental principle of the universe relative theory is the principle of equivalence. The principle of this principle is that it is not possible to say that you are in a gravitational situation, or you are running with the rate of acceleration in the lowest place.
There is no problem in understanding this serious word. Instead, let's look at an example. Remember, you are in a lift in space, where the gravitational force is missing. As a result here over. There is nothing to say about bottom or bottom. You're floating freely After a few minutes, the elevator began to move on. Now but you suddenly feel weighed. Feel a tension on one side of the elevator. Now this aspect will feel like you have a floor!
Now if you leave an apple from the hand it will move towards the floor. In fact, the acceleration of everything inside the elevator is now just like you. It seems as though the elevator is not dynamic at all, but it is in a balanced gravitational field. Einstein realized that while sitting inside the train you can not say that you are not walking or going in the same way, even sitting inside the elevator you one-second understand whether you are in a balanced acceleration or in a balanced gravitational field. The result of Einstein's thought is the principle of equality.
The Principle of Equality
The principle of equality and the above example is true if the mass and gravitational mass of the object must be the same thing. Depending on the amount of acceleration due to the force applied depends on the mass. This mass is said to be the second formula of Newton's motion. The gravitational mass on the other side is in Newton's gravitational formula. The amount of gravitational force you feel will depend on the mass.
I learned the principle of equality. To keep pace with the principles of Einstein, one has to do a lot of experiments. Thought Experiment is a test that can not be done in reality, it is understood by thinking. This time the experiment or thinking experiment will show us how gravitation affects time.
Think of a rocket in space. For the sake of convenience, think the rocket is so large that it takes one second to reach the light from the top of the floor, that is, its length is 1 million 86 thousand miles. Think more about the rocket ceiling and the floor on the floor. Both of them have exactly the same timepiece that ticks in every second.
Remember, the ceiling fans are waiting for the clock tie. After getting the tick, he sent a light sign to the floor viewer. After ticking the clock again, he sent another signal. In this situation, each signal reaches the floor viewer after one second. When visitors of ceiling send two alerts in one second, floor visitors will get two seconds of intervals.
If the rocket was not gutted in space, then what would happen if the rocket was in the gravitational pull of the Earth? According to the Newtonian theory, there is no gravitational force in this incident. The visitors of the ceiling will receive second intervals between the floor visitors in a second. But the principle of equality speaks differently. Let's see what we get by thinking about the balanced acceleration instead of gravity using the principle. This is an example of how he used the principles of Einstein Equivalence to create his own gravitation theory.
Suppose the rocket is running with acceleration. That is, every moment of its velocity is increasing. We have been taking the time to evaluate the value of its scalability, otherwise, it can reach the speed of light once again! As the rocket is dynamic at the top, the first sequence has to travel less than before (when the rocket was fixed). So, the signal can now be reached at the bottom before it passes a second. If the rocket was moving at a certain speed (non-accelerated), then all previous alerts reached a second. But the second sign will have to pass a lesser distance as there is acceleration here. As a result, it will take less time to reach. So the floor viewer will get time interval between two signals less than one second. While the ceiling visitors sent it just a second. The time has not happened.
It would not be strange to have such an accelerated rocket. But it should be kept in mind that the principle of equality suggests that if the rocket stays in a gravitational field, the same thing will happen. That is if the rocket is not accelerated (for example, it is set to launch on the surface of the Earth), even if visitors of ceiling send two signals after one second floor visitors will get it less than a second. It looks strange, is not it!
Gravity Time
Maybe there will be questions on the head, what does it mean? Gravity is distorting the time, or is it stopping the clock? Suppose, floor viewers climbed the clock with the ceiling audience. It was found that two watches were exactly the same. They also make sure that both understand the equal amount of time in one second. There is no problem with the floor viewer's watch. Wherever it is, it will measure its local time flow. Special Relative Theory tells us, the time for the different movement of the viewer moves at different speeds. And overall theoretical theory says the speed of time differs at different altars of the same gravitational field. According to overall relative theories, floor viewers have received less than a second, because the time is relatively slow for the surface of the Earth. If the gravitational field is strong then this effect will be more. The idea of the absolute place was taken by Newton's motion formula. Now the relative theory farewell to the absolute time.
In 1962 this estimate was met with a test. Two ultra-fine watches are placed above and below a water tower. It was seen that in the lower clock (which is more than the surface of the Earth), the time is moving slowly, just as the overall theory of relation was predicted. This effect is very small. Any clock placed on the surface of the sun will show only one minute difference compared to the surface of the Earth. But at the height of the world's height, this small difference in time plays a very important role in the real world. It is necessary to keep our navigation system updated with satellite signals. By ignoring the impact of the satellite, it will be a few miles away!
Due to the difference in the time flow of our body. Think of a pair of twins, one of whom lives on the top of the hill and another sea level. The first person will grow faster than the other. When you meet again, you will see one older than the other. In this case, the age difference will be very small, but still, it is a difference. On the other hand, if a person travels long by traveling in space near the speed of light, then he can see that his age is much less than the twin.
If you travel far enough to go far away from the world of special relativism, you will be relatively less. And if you are away from the surface of the Earth, in the overall relative theory, the age. Grow faster An effect is apparently opposite to another. However, there is no such thing that you will have to go through space in a rocket to take special relative theories. Even if you travel on an impossible train in the world, you will be less than your friend on the train.
It is called twin paradox. But if you put the concept of absolute time in the head, it would only be considered a paradox (incompatible or apparently impossible). There is nothing to say about absolute time in a relative theory. Rather, each audience measures the time of his own time. It does not have any paradox if you accept it.
