## Abstract
In this seminar, I will introduce some others' work about how to solve the Hubble tension. I will explain why the late time physics may not slove the Hubble tension. Besides this, I will share a recent paper about Sensitivity of the Hubble Constant Determination to Cepheid Color Calibration.
In this talk, I will introduce my recent work about nonlinear elasticity of granular matter. On one hand, we obtain stress-strain cueves by simulating. This part was studied by collaborators, I will give a brief introduction to this part. On the other hand, our holographic model is able to give this curve. Besides, yielding points between two methods also match qualitatively. Because there's some difficulties to evaluate entropy, our holographic model could give a prediction.
