“Science use the scientific method.”
The scientific method does not predict the future. It only verifies the past.
You have to have models to predict the future. Most modeling is performed on computers.
The scientific method most certainly DOES predict the future. The whole purpose of a well-designed scientific experiment is to establish cause and effect in such a way that other scientists can repeat the experiment and get the same result.
If you want you can call Newton's Second Law, "F=ma", a model. It can certainly be calculated on a computer. It was established as a scientific fact long before computers existed. It not only explains the past but also predicts the future; apply a force to a mass and you can expect to see a predictable acceleration.
"F=ma2" is a different model. You can calculate acceleration using this model, but you will not be performing science and it will neither explain the past nor predict the future.
Just because you "have to have models to predict the future" doesn't make those models science.
You are soothsaying with superstitious digital chicken entrails, you just want to call it 'science' so you can tell people "the 'science' is settled therefore you have to shut up and obey us."
