In 2019, the first picture of a black hole, its birth, verified the prediction of Einstein’s theory of gravity for black holes, opened a new chapter in the human exploration of the black hole at the center of the Milky Way. So how is this picture taken? What exactly is a black hole? What is the point of human research on black holes? What is the content and significance of black hole physics research? Academician CAI Ronggen conducted a detailed professional science popularization at the scene.

“Scientific research is a constant process of trial and error.”” A theory must be tested by experiments.”Cai Ronggen academician from the” three apples “, through the Newton, the story of Albert Einstein to encourage the students present, on the road of science to have the courage to explore, insist to explore,” those full of strong desire, over the years in the dark anxious exploration, sometimes confidence and sometimes exhausted, finally bathed in the light.”

In the interactive session, the students asked questions from Academician CAI from the perspectives of basic science, science fiction movies and physics learning.
“After learning of this activity, the students were enthusiastic about signing up, and nearly 500 students wanted to listen to the academicians’ popular science lectures. Academician CAI has a strong theoretical and physical foundation, which is admirable. He can explain the complex scientific knowledge clearly in simple language, which is worth learning.”Zhu Xingwang, a physics teacher from Hangzhou No.14 Middle School, said after hearing the lecture,” I hope there will be more opportunities to have close contact with academicians and scientists in the future, so that the seeds of science can be sown in the hearts of more students.”
“Academician CAI’s lecture is very interesting. In today’s popular science, I saw “the Three-Body Problem” and “Interstellar”, these science fiction novels and science fiction films mentioned in the science issues, very cordial. Through academician CAI’s theoretical analysis, I have a deeper understanding of these knowledge. There are many unsolved mysteries about black holes, which gives me the idea of understanding the stars overhead.”Said a student from Hangzhou No.14 Middle School.
