More gibberish!
Hey! Don't go off insulting gibberish!
That may not be what's happening. We can't judge that until Gibberish replies for himself.
And here he is!

We consider an observer who moves under the horizon of the Schwarzschild black hole and absorbs a photon. There are two qualitatively different situations when (i) a photon comes from infinity, (ii) it is emitted by another observer near the past (illusory) horizon. We analyze the frequency change for absorption near the event horizon and near the singularity. In general, the result depends strongly on the angular momenta of an observer and a photon. For pure radial motion, radiation inside the horizon experiences ubounded redshift in case (ii) and, moreover, near the singularity this is valid also for case (i). For nonzero momenta, it has a finite frequency or experiences the unbounded blueshift. There is scenario in which the ubounded redshift in the intermediate region inside the horizon changes to the unbounded blueshift when an observer approaches the singularity.

Therefore if we can light that has red or blue shifted as result of a black hole then said light will traveled x number of light years reaching the Earth, which in turn that red and blue shift light would be part of the process for plants to develop their defensive measures from.

BBC article on imaging of one of the jets of another blazar* (3C 279) by the Event Horizon Telescope team using VLBI.

The physics of how such jets extract energy from the black hole is not well understood. Images such as these should help to refine and choose between theories.
* A blazar is a type of quasar where one of the two relativistic jets of the active galactic nucleus (AGN) happens to be directed in the general direction of earth.

I am reminded of the words of the physicist Wolfgang Pauli, who said: "Das ist nicht nur nicht richtig, es ist nicht einmal falsch!"
(“That is not only not right, it is not even wrong!”)

This black-hole collision just made gravitational waves even more interesting
An unprecedented signal from unevenly sized objects gives astronomers rare insight into how black holes spin.
