Stand next to a wall that travels at 30 km/s relative to the Sun. In some instances, rather than rejecting a hypothesis because it has been falsified by new evidence, scientists simply adapt the existing idea to accommodate the new information. A scientific theory summarizes a hypothesis or group of hypotheses that have been supported with repeated testing. A key function of a hypothesis is to derive predictions about the results of future experiments and then perform those experiments to see whether they support the predictions.
