How do scientist draw a conclusion when it is impossible ro conduct an experiment?

When conducting experiments is not possible, scientists often rely on observational studies, existing data, and theoretical models to draw conclusions. They may analyze patterns, correlations, and relationships within the data to infer possible outcomes. Peer-reviewed literature and prior research findings also play a crucial role in validating their conclusions. Additionally, scientists may use simulations or statistical methods to make informed predictions based on the available evidence.
