Final answer:
A hypothesis that is supported by many different research studies and substantial evidence evolves into a scientific theory, representing a broad and well-established explanation in science.
Step-by-step explanation:
In science, a hypothesis that has been rigorously tested and consistently supported by a substantial amount of evidence from many different research studies is known as a scientific theory. While a hypothesis is an initial supposition that can be tested through data collection, a scientific theory represents a broader and more established explanation. This theory has undergone repeated testing and verification, and as such, it holds a significant place in the scientific community as a well-substantiated explanation of an aspect of the natural world.
