When I was in middle school, the teacher said that the speed of light could not be surpassed, and the speed of light could not be superimposed. I asked the teacher why? Remember that he said that this was determined by the nature of light, the result of Einstein's research.
Thirty years have passed, and the other day I had dinner with my relatives, and I talked about light, time and space, and so on, which I actually couldn't understand at all, but I always liked to express some opinions. East and west, paste and chaos, so not lively.
Lying in bed at night, my brain still can't stop, and the problem of the speed of light has been thirty years, and I have never understood it. Some people say that this is the conclusion of the theory of relativity, and it is necessary to understand the theory of relativity to understand the problem of light. OMG! The theory of relativity, there are several people in the world who understand it. I certainly don't expect it in my life, let alone understand the theory of relativity, it is difficult to accept it. If I hadn't thought that Einstein should be a reliable person, he would never have believed in any relativity. I couldn't sleep for a long time, either because I wanted to seek some truth or to find a reason to make this matter round.
The only physics I had in mind was that bit of Newtonian mechanics. No matter how much I know, I can accept it and believe it. It fits my logical cognition and life experience. It doesn't matter who Newton or Einstein is right and who is right, what matters is that I explain what I don't understand with what I understand, and let it be what I understand. It doesn't matter if others believe it or not, what matters is that I believe in myself, that I want to be my own wizard.
Me: Why can't light be accelerated?
Wizard: Because light has no mass, according to Newton's formula F=ma, it can be deduced that a=F/m, if m is 0, this equation is meaningless. So light cannot be accelerated.
Me: So surely objects with mass can be accelerated?
Wizard: Yes.
Me: Since objects with mass can be continuously accelerated, why can't they exceed the speed of light?
Wizard: Of course we can transcend, but after transcendence, we cannot observe and measure. So it should be understood that the speed at which we can observe cannot exceed the speed of light.
Me: Why?
Wizard: Because light is our tool for observing the world. Beyond the scope of this tool, we can't observe.
Me: Well, that's a good explanation, it's simple, it's easy to understand. I can sleep. (End)
