Answer:
You can consider a vacuum tube simulation, in which an electron is allowed to move from the lowest point to the highest point. And this can be compared with the universe, and how the big bang theory occurred. The distance traveled by the electron is the distance traveled by the farthest particle in the universe to date. And thus, we can calculate the age of the universe, and which comes out to be 13.7 billion years. Thus, the above is a physical simulation, and through a computer simulation program on the computer, we create a mathematical model and find the age of the universe. Many more examples can be sorted out like weather forecasting, flight simulation, and car crash modeling.
