lang=EN-US style='font-size:12.0pt;font-family:等线'>This year's Nobel Prize in
physics goes to black hole research today. 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.<u1:p class=""></u1:p></span></font><font
