It's easy to forget that astronomers and theorists are oftentimes forced to interpret still images. A series of still images leaves a lot to the imagination, which theorists are more than happy to fill in with their models. If these guys are saying that they can now observe planetary formation in video, then the public needs to pay close attention to how well their observations are matching the theory. This is incredibly important, as it speaks directly to whether or not gravity is indeed the universe's dominant force. Their first instinct, if the models are dramatically wrong, will be to blame invisible entities. People who are paying attention need to not be so gullible, and also wonder if the observations are telling us that the gravitational accretion models are just wrong. At the point where we no longer question these models, then the models become more of a belief system than science.
