How long did it take me to fly from the earth at the speed of light to return to the earth at the same time, Is the time around him almost stagnant? Does it not mean that the faster the relative object is, the slower the time passes? How many years have passed on the earth? If it is 2 years, what is the difference between my time and that on the earth?
In your life, you don't spend time, your time, has not changed, but the earth is two years, but you fly at the speed of light, your everything will be static, including your mind
Why does time slow down when the speed is close to the speed of light
The last sentence on the second floor is correct. People on the spaceship will not feel any change in their own time. Time slows down from the perspective of observers on the earth. Relativity abandons the absolute time in Newton's view of time and space. Without absolute time, time will become faster and slower in the natural universe
In the theory of relativity, the speed of light is constant in any inertial frame. No matter how the observer moves, the speed of light they see is always constant, The speed of light can't be static relative to the person on the spaceship. The speed of light is always the same 300000 km / s whether the person on the spaceship or the person on the earth. In the theory of relativity, the two speeds in different inertial frames can't be directly superimposed by Newton mechanics. First of all, the two speeds can be added by Lorentz transformation
Why does time slow down when the speed is close to the speed of light
First of all, this is a problem in special relativity. It is based on two hypotheses: 1. The speed of light is constant for any observer. 2. In any inertial reference frame (i.e., the reference frame that is stationary or moving at a constant speed), the physical law takes the same form

- 1. Is it right that the speed is close to the speed of light and time slows down or stops? Time is just a concept. It is a unit of measurement of the regular change of matter. For example, year, year, and day. I don't understand that if we move at or near the speed of light, time will slow down or stop. The original meaning is: can the speed of light slow down the change of matter? What kind of trajectory is needed to produce such an effect? Is it linear motion or circular motion or rotation? Personal feeling: suppose there are two children just born when the speed of light train starts, one is on the train and the other is at the departure station. After 20 or 30 years, their life change characteristics should be the same (in short, the aging degree is the same), If the train returns to the departure station at the speed of light 20 years later, is it a meeting between two young people, or a meeting between a young man (on the platform) and a baby (on the train), The minute of a stationary person is infinitely lengthened in his life cycle). If it is the period of material change that slows down, will people on the train with the speed of light feel that their life has changed a lot? (the train has been running for 1000 years, but they have not changed at all)
- 2. Why does it slow down near the speed of light
- 3. How to understand that a year spent in a spaceship traveling at the speed of light is equivalent to a million years on earth? For example, there should be no reference to time, it is absolute. For example, my watch in the spaceship will walk slower, the same watch, the pointer speed is the same, how can it be placed on the spaceship to walk one circle time, the earth will walk ten circles

It is known that the mass of the earth is about 81 times that of the moon. The spacecraft is attracted by the gravity of the earth and the moon on the way to the moon. When it arrives at a certain area, the resultant force of gravity is equal to zero. How far is this area from the earth
- 7. The mass of the earth is about 81 times that of the moon. When the spacecraft passes through a certain position between the moon and the earth, the gravity of the moon and the earth is equal. The distance ratio from the position to the center of the moon and the center of the earth is () A. 1：81B. 1：27C. 1：9D. 1：3
