Answer:
scientists can only use the information available at the time to create their models
Step-by-step explanation:
I am doing classes on this and scientific theories. For in the past the models they used back then were amazing. Like the "plum pudding model" it was inaccurate but at the time it was accepted because it was backed by science. Now that we have advanced tools and machines to help us models are now more accurate then ever. In 30 years from now people can look back and think our scientific models were bad because they found better information to make models even better.
( I hope this helps you!)
