Universe, four dimensions of time and space, general relativity, quantum mechanics ......

Today, after having slept for half a day, I read a small part of the book "black hole, baby, universe and others" written by Hawking, plus a long time ago I read his book "A Brief History of time". I feel that I have benefited a lot. Those theories have really surprised me, and even gave me another way of looking at the world and imagining how a mass of material causes space-time distortion, imagine the light refraction caused by a large number of constant stars as a lens, so that we can observe what the galaxy is like 13 billion light years away. Imagine the stars I saw at night, it's just watching the History of a star in different time and space. At this moment in my space and space, we see the light emitted by this star 1 million years ago, the light of the star 0.7 million years ago may no longer exist when I saw the light of a star. Imagining the theories described in the book is amazing and hard to imagine ......

I am also very interested, but I know that all these theories are built on complicated mathematical models and a lot of long-term observation and analysis. I want to face those things, I have a headache. I want to be an ordinary reader, but it is enough to know that my physical score is second only to the second highest in Chinese when I took my college entrance exam.
