A theory may be revised or discarded in the future if new evidence emerges that contradicts its predictions, if it fails to explain or account for new phenomena, or if a more comprehensive and predictive theory is developed that encompasses its core principles. Additionally, changes in scientific paradigms, advancements in technology, or shifts in scientific consensus can also drive revisions or discarding of theories.
While NASA is a reputable organization with a long history of successful missions and discoveries, it is not infallible and can make mistakes like any other human endeavor. Scientific research and exploration involve a degree of uncertainty, and new information or data can sometimes lead to revisions or updates on previous findings. NASA's commitment to transparency and peer review ensures the accuracy and reliability of its work.
Yes, a model can change as new discoveries are made. New discoveries may bring new information that could challenge or enhance existing models, leading to revisions or updates to better reflect the latest understanding of a particular phenomenon or system. Science is an iterative process, and models are continuously refined based on new evidence or insights.
As with all branches of the sciences, as new evidence comes to light, old ideas receive revisions or are sometimes abandoned for improved ideas. It was once thought the planets and Sun orbited the Earth; later it was realized it was more accurate to say the planets orbited the Sun since that notion was more consistent with observations.
One theory is that the earth and moon were originally one planet, but that something (perhaps a collision from another large body) caused it to split into two unequal parts. Neither part, obviously, was originally spherical, but centripetal forces and gravity, over thousands, perhaps millions, of years, shaped them into spheres. A variant on this theory has one or both of the bodies being completely obliterated by the impact, then eventually pulled back together, by gravity, into two separate bodies. == See the linked question below [Is the moon artificial] for some other possibilities for the origin of the moon.
