• 2. One second =? Light year =? Astronomical unit =? Kilometer =? Meter =? Centimeter must be accurate!
• 3. Formula expression of measuring light speed by rotating prism method Suppose that the distance between the two peaks is l, the rotation of the eight prisms is t, and the rotation time is one circle, then the formula of the speed of light is v = 16L / T? (the answer must know what he measured.)
• 4. Can Maxwell's equations deduce the principle of invariable speed of light? In Baidu Encyclopedia, it is said that the principle of invariable speed of light is obtained by solving Maxwell's equations. Is that right? If so, why did scientists at that time think that there was ether and that the speed of light was variable
• 5. Derivation process of solving Maxwell equations
• 6. How to deduce that the speed of an object cannot reach the speed of light from Lorentz transformation Can it be deduced from the basic principles of relativity?
• 7. I wonder if Einstein said that we can't go faster than the speed of light, then why did he say that we can go through time and space when we go faster than the speed of light? Does Einstein want to say that it is impossible for us to travel through time and space? Since he thinks that it is impossible for us to travel through time and space, why should he say that we can travel through time and space beyond the speed of light? What does he think about traveling through time and space? P. S. even is additive P. S. I'm additive. I have no idea about relativity. Please don't post special relativity and general relativity here. It's too abstruse for me to digest

• 9. [superluminal speed] what happens if a person walks on a train moving at the speed of light? I mean, listen to me: Let's say I'm standing on a railway that faces east and West. I'm an observer, I'm carrying a camera, and I'm fixed to a point on the railway. Then I see a train moving at the speed of light in front of me coming towards me (if I can take a picture of it, but it can't hit me). At the same time, there are two passengers on the train, a passenger a, One passenger is B. passenger a has been sleeping in the sleeper compartment of the train, and he and the train are relatively static. The other passenger B wants to go to the toilet in front to pee. When passenger B stands up and walks in the positive direction (that is, the direction of the train) at a constant speed "V", look at the train in front of me and passengers a and B on the train, What will I see? (I give the following three answers, I don't know if they are correct.) 1. The speed of a train is the speed of light, 2. The speed of passenger a sleeping in the sleeping car is also the speed of light, 3. The speed of passenger B walking to the toilet is the speed of light + V, faster than the speed of light? (this may not be right, because according to Einstein's special theory of relativity, the speed of light cannot be surpassed.) So the key question is: If the train can't go to the toilet, how can he still see if he can't go to the toilet at the speed of 50 meters I don't agree with "speed of light + V can still be regarded as the speed of light" answered by "likeren 2010" on the first floor, because the speed of light is not to be surpassed. For any object, the speed of light can only be lower than the speed of light in vacuum. It is impossible to surpass it, even if it is only 10-100 million cubic meters / second, let alone surpass the speed "V". Therefore, the answer on the first floor is groundless As for the answer of "let others not hurt" on the second floor, I think you misunderstood me. The car has been broken down, and what's wrong with this assumption? You're here to make trouble. Identification is over

• 11. What is the relationship between the sun, the earth and the moon?
• 12. The relationship between the earth, the moon and the sun, how they work, how time is counted,
• 13. Is it because the earth is too far away from the sun that the four seasons of the earth and the phases of the moon change? If you have any questions, please give me your advice 1. The volume of the sun is 1300000 times that of the earth. Can I think that: If the sun is at zero distance from the earth (if it doesn't vaporize the earth), will there be no day and night change, no four seasons change, and no moon full or clear? Because the sun can shine on almost every corner of the earth and the moon all the year round, that is, all the surface of the earth and the moon is in the extreme day all the year round Now, the reason why the four seasons change is that the sun is so far away from the earth that it almost turns into a parallel light and has no angle Is that right? 2. There is another problem Suppose that there is only one sun and one earth in the vast universe, then we adjust the distance between them from zero to infinity, will there be such a change: the earth is full bright at first, and then the dark part gradually increases until it is completely dark? Is this assumption correct?
