Cendes and her team determined that this material is being ejected from the black hole at around 300 million mph (480 million kph) — about half the speed of light. For comparison, TDEs usually spit out this material at about 10% the speed of light.

So it’s traveling much faster then previous observed half the speed of light , wouldn’t we as the “stationary observer” observe the second part of the event of it slingshotting away from the event horizon later to preserve relativity? And see it a few years later?
