No, all physical quantities in the world have virtual space values. The law of large numbers holds that space must be real, so mean is more important than variance. When you read any physics textbook, you are not talking about the average value, but energy. A simple deduction shows that there is no uniform motion. Vibration is the essence. The conservation of mean will lead to normal distribution, which will be impacted by its own zero expectation and the error will accumulate. In other words, if something is a random variable but has a mean value, its energy will be infinite. Of course, energy cannot be infinite, so the conclusion must be that this thing is not a random variable. In other words, if a data conforms to the normal distribution, we should think that there is some mechanism to make its conclusion unique. It should be the sum of a constant and a number with zero energy at infinity. As long as it is a random distribution, it cannot be a normal distribution. Uncertainty is the essence of all physical quantities, that is, all physical quantities should be random variables, so they cannot meet the normal distribution.

What is a stock? The financial market has existed for 100 years. Why do financial markets never conform to the normal distribution? Because financial markets are about uncertain transactions. About the expected transaction.
