Which statement best describes how an existing theory is often affected by the development of new technology?

an existing theory is thrown out and replaced with a completely new theory based on the new observations.
an existing theory is modified so that it can explain both the old and new observations.
an existing theory remains the same because a theory is a proven fact that is always true.
an existing theory is kept unchanged while a new theory is developed to explain the new observations.

An existing theory is modified so that it can explain both the old and new observations.

A theory is a well-confirmed explanation of a phenomenon, most of the time associated with scientific studies. It requires the use of a consistent scientific method, which includes observation and experimentation. A theory should be written in a way that allows for it to be proven wrong. Theories are often challenged when new evidence comes to light, and this is the main way in which science progresses. When this happens, theories are usually modified in a way that explains both past and present phenomena.
