People don't live with the length of time. Because the length of time is just a wrong understanding, superstring universe theory holds that the universe has 1 1 dimensions. And humans can only feel four dimensions. In other words, time is meaningless if it can operate outside the dimension. There is also the recent neutrino superluminal, which also shows the correctness of string universe theory.

The other is time entropy (Shang). If the forward time entropy collapses, the reverse time entropy will flow backwards, so time will be reversed.

Width and thickness need to be expanded with thoughts and knowledge. Thinking can make people deeper. When you reach this level, the problem you are thinking about will become connotative, not just a question of fame and fortune. Learning can broaden your horizons and let you learn to look at problems from different angles. For example, Mobius ring belt superstring universe theory, entropy universe theory and parallel universe theory.
