First, the body of scientific knowledge is continually evolving. Scientists don't simply add more facts to our scientific repository; they question new evidence as it comes in, and they repeatedly reexamine prior conclusions. That means that the body of scientific knowledge isn't just growing, it's also changing.

Is science open to change?

Scientific explanations can be probabilistic. Most scientific knowledge is quite durable, but is, in principle, subject to change based on new evidence and/or reinterpretation of existing evidence.

Does science Change Why or why not?

Historians of science have shown that scientists use many different methods, and these methods have change with time. Science is dynamic: new methods get invented, old ones get abandoned, and any particular juncture scientists can be found doing many different things.
