"If the objects are real, and (big) if they are violating the laws of physics as we know them, that means that our understanding of physics needs to be revised.

"If the objects are real, and (big) if they are violating the laws of physics as we know them, that means that our understanding of physics needs to be revised. Physics is physics." One little issue here though. The current understanding of physics is the result of study performed on inert systems, under total (or big enough degree of) scientists' control. Areas which aren't easy to be subjected to experiments are avoided. (Among other things, choosing something like that would pose a high risk of loose speculation on the limited data sets at hand, and an even higher risk of results staying unverifiable by independent parties, both reflecting badly on the scientists involved.) When confronted with something hardly explainable like UFO reports, the easy way out is denial or questioning the source and information veracity.
