Indeed God does not play dice. When God plays by quantum rules, we can only guess or use a frequency table derived from the quantum laws to predict the outcome, but we do not know how God does it! The quantum theory tells us that if some things are certain then other (complementary) things are correspondingly uncertain. This follows from the mathematical model and it is born out in our observations. Some properties of quantum objects such as momentum and position are not intrinsic properties of the objects.

When the curvature of space-time of a celestial body is so large that even light cannot escape from its event horizon, we call it a black hole. I. Once a black hole is formed, except for mass, angular momentum, and electric charge, all the previous material properties as objects disappear; II. The horizon area of the black hole is equal to its entropy (entropy equals negative information). These two issues form a close relationship between the research of black hole and information. The follow-up effect of this year's Nobel Prize in physics may lead to further thinking on the information in the future by astrophysicists, and lay a reverie foundation for the informational interpretation of matter several years later.<u></u><u></u></span></font><font size="2" face="等线"><span style="font-size:10.5pt;font-family:等线"><u></u><u></u></span></font></div></div><div><div
