"Suspect Explorer" Note:
String Theory is a great attempt to standard model. At present, the main thing that is studying string theory in China is Li Miao , and it is said that Xiang Haibo is also But now is the coldest period for string theory. First, mathematics has not made any breakthroughs, and second, it is impossible to create such a large amount of energy experiments. According to estimates, one thinks that the accelerator diameter needs 1 light-year, and more exaggerated one thinks that the accelerator diameter may be required at least 100,000 light-years. This is really impossible to continue. So even Weiteng has changed careers long ago.
Standard Model Particles are extremely supersymmetric partners
The mainstream academic community in the international community held several meetings. At present, string theory is not recognized as a scientific theory, and believes that it is a kind of "physics metaphysics ". In short, it is believed that string theory is philosophy and does not belong to science.
philosophy, there are too many flaws, the key is the lack of empirical means.
Of course, this is also temporary, and it is possible to find a better way to verify the feasibility of string theory in the future. But as far as I see, string theory is of course a little bit more clever than philosophy, because after all, it has several sets of mathematical models in it. Modern philosophy also tried to introduce mathematics, but it was not very clever and seemed like nonsense. Overall, philosophy is still in the stage of random guessing.
So, string theory, does it belong to random guessing? Actually, that's true, but not all. Because there is a mathematics that does the underlying design.
I recommend two articles now. I have read them several times and introduced the ins and outs of string theory well and its practical difficulties. Among them are comments from the famous scientist Wen Xiaogang .

I hope the above two articles can help you.
