But that would take infinite time (as we perceive the event) because of time dilation.
You would not see it "turn on", you would see a slowly, very slowly, changing signal.

When an accretion disk is actively ripping apart a celestial body the plasma is some of the hottest material in the current universe. It's extremely violent and bright. You're seeing a gravitational well converting a huge quantity of mass to energy.
Moreover, I believe that the radiation from an object falling into a black hole is redshifted so rapidly, that it effectively disappears from view in a very short time. An outside observer would not see anything “lingering” near the event horizon.
If the wavelength is a million longer, any event that would take 1 second to happen, appears to us as it took 12 days.
And what probably really happened is that the star was massive enough that it caused the black hole to start emitting jets. There are always two of these pointed opposite one another, and one happened to be pointed toward us.
At the radius of the accretion disk, the effect will usually be small enough that we’d need some careful measurements to detect it.
* Instead of a black hole eating a star, a plasmoid is having an increased load. * Black holes are "gravitational" machines while plasmoid are "electromagnetic" machines. * With the plasmoid model there is no time dilation * With the plasmoid model, the load is any source of plasma, not necessarily a star

But there is time dilation, so the plasmoid model isn't very good at explaining observations.
Also, the idea that you’d want a model that avoids time dilation here makes no sense. We know gravitational time dilation is a real effect because we’ve measured it, it matches the predictions of general relativity, and GPS would be very inaccurate if they didn’t correctly take the effect into account. To say that time dilation doesn’t occur near a black hole is completely inconsistent with well-verified facts.
From this, we can conclude that Lerner’s conjecture is wrong. We can’t even call it a theory, because it doesn’t match the evidence.
