How did a space enthusiast / retired VFX artist correctly predict the failure of the expert analysis of NASA's DART team ?

NASA frankly admits they cannot explain why some of the ejected material from #DART impact forms curved "rays". NASA expected that most of the material would remain gravitationally bound.

Dimorphos was to be spotted as early as 120 minutes before impact.
But even 80 minutes before impact, there was no sign of Dimorphos.
