Chapter 17 siege

Every era has the unbreakable concept of that era, just like a strong castle, the leap of the times, the progress of mankind, represents the fall of each castle. Only hundreds of years ago, people still believed that weight was absolute, and a thing weighing three pounds should be three pounds wherever it was measured, so Newton came, and he told us that the same thing, measured on a high mountain It will be a little lighter than when measured in the lowlands, the weight is not absolute, it is determined by the universal gravitation.In the void far from Earth, weight may not even exist.Thus, the castle of weight fell.

More than a hundred years ago, human beings believed that time is absolute, that an hour is an hour, and a minute is a minute, so Einstein came, and he said that time is only relative, and as the speed increases, time will slow down.A clock on Earth will run a little faster than a clock on a rocket sprinting at high speed.The farther the speed difference, the greater the difference.Time will also be affected by the force field, and time in the black hole will exist at another speed.The castle of time has fallen. When we look back, we will naturally be complacent, looking at the thick smoke from the fallen castle, blown thin by the wind, but we must not be volitional, because we are just standing on another new castle of self-righteousness, Describe the beauty of ice as a summer insect.

One day our castle will be just another pile of rubble.
