    Because of the Druids. You can see it in their cloaks.

    Honest officer,that black hole came out of nowhere!:biggrin:

    Plants are particularly prone to photo-oxidative damage caused by excess light. Photoprotection is essential for photosynthesis to proceed in oxygenic environments either by scavenging harmful reactive intermediates or preventing their accumulation to avoid photoinhibition. Carotenoids play a key role in protecting photosynthesis from the toxic effect of over-excitation; under excess light conditions, plants accumulate a specific carotenoid, zeaxanthin, that was shown to increase photoprotection. In this work we genetically dissected different components of zeaxanthin-dependent photoprotection. By using time-resolved differential spectroscopy in vivo, we identified a zeaxanthin-dependent optical signal characterized by a red shift in the carotenoid peak of the triplet-minus-singlet spectrum of leaves and pigment-binding proteins. By fractionating thylakoids into their component pigment binding complexes, the signal was found to originate from the monomeric Lhcb4–6 antenna components of Photosystem II and the Lhca1–4 subunits of Photosystem I. By analyzing mutants based on their sensitivity to excess light, the red-shifted triplet-minus-singlet signal was tightly correlated with photoprotection in the chloroplasts, suggesting the signal implies an increased efficiency of zeaxanthin in controlling chlorophyll triplet formation. Fluorescence-detected magnetic resonance analysis showed a decrease in the amplitude of signals assigned to chlorophyll triplets belonging to the monomeric antenna complexes of Photosystem II upon zeaxanthin binding; however, the amplitude of carotenoid triplet signal does not increase correspondingly. Results show that the high light-induced binding of zeaxanthin to specific proteins plays a major role in enhancing photoprotection by modulating the yield of potentially dangerous chlorophyll-excited states in vivo and preventing the production of singlet oxygen.

    Therefore the black hole that is aimed at the Earth would, in some manner, assist in creating red shift that would help protect plants from excess light. Micro black holes in a solar system might also create essential red shift for plant life.

    That's not how it works... That's not how any of this works!

    Red Shift in Astronomy has to do only with the wavelength of the light we observe as it is "compressed" or "stretched" due to the relative difference in velocity between the observed light and the point of observation.

    What that article is discussing has NOTHING to do with the subject of Red Shift (or Reverse Red Shift/Blue Shift) in Astronomy. It's purely discussing the way in which plants THEMSELVES protect themselves from excess exposure...

    ^^ I applaud your patience..
    Dryson, you can't just pile a few totally unrelated phenomena on top of each other.

    /\Heh!
    New to the internet are you??Or indeed the 21st century.
    Never let logic or fact get in the way of an argument.

    kidding friend.

    https://www.researchgate.net/publication/45720939_A_Red-Shifted_Chlorophyll

    Chlorophylls are essential for light-harvesting and energy transduction in photosynthesis. Four chemically distinct varieties have been known for the past 60 years. Here we report isolation of a fifth, which we designate chlorophyll f. Its in vitro absorption (706 nanometers) and fluorescence (722 nanometers) maxima are red-shifted compared to all other chlorophylls from oxygenic phototrophs. On the basis of the optical, mass, and nuclear magnetic resonance spectra, we propose that chlorophyll f is [2-formyl]-chlorophyll a (C55H70O6N4Mg). This finding suggests that oxygenic photosynthesis can be extended further into the infrared region and may open associated bioenergy applications.

    [SIZE=6]PSO J030947.49+271757.31 is 13 billion light years away from Earth. Earth is 4.543 billion years old. Thus the region in which Earth formed in was already encountering Red and Blue Shift light from the black hole for 8.457 billion years before the Earth formed.

    The last time that I checked Red and Blue shift are forms of light that plants due in fact interact with or is that not true either? Therefore Red and Blue shift does impact the way that plants grow and develop on a planet and as such PSO J030947 would effect the plant growth and development on Earth. [/SIZE]

    It's not true the way you mean. The items you're quoting are two different and unrelated uses of the words "red shift". Trying to put them together is leading you to erroneous conclusions.
    • "Red shift" in the context of plant life refers to changes in the part of the spectrum in which certain plants absorb light.
    • "Red shift" in the context of black holes refers to our relative perception of any stellar body due to the Doppler effect.
    Two different meanings to the term.

    There is no direct connection between this black hole and plant life on Earth.

    Red Shift or Bathochromic Effect: A change in absorbance to a longer wavelength (λ).

    http://faculty.chas.uni.edu/~manfredi/860-161g/UV-VIS terms.pdf

    https://www.ncbi.nlm.nih.gov/pubmed/699913

    The Sun is 4.603 billion years old and is not much older than the Earth.

    Rocky and Ice chunk debris passing through the Solar System for many billions of years before the Sun formed would have experienced pre-Sol System Red and Blue shift light coming from the black hole. The material contained in the rocky and icy chunks would have experienced red and blue shift long before the Earth was formed. The red and blue shift light interacting with the elements would have caused other interactions to take place that could have created microbial plant life necessary for the Tardigrade to feed on while in space. The Tardigrade can survive in space longer than any life in the Universe that we know about. Without some type of plant life for the early Tardigrade to feed on while post-Big Bang debris coursed through space, Tardigrades probably wouldn't exist.

    Therefore due to the red and blue shift of the black hole, planets or post Big Bang debris that is closer to the black hole would have experienced red and blue shift at a faster rate than Earth, meaning that planets closer to PSO J030947 that are aligned to the black hole similar to how Earth is could have life on them.

    Don't even try.. I mean, a discussion, it simply isn't possible..

    A planet closer to a black hole would possibly have more toxic and aggressive species of plants that in order to survive the plants would have to consume other plants for nutrients they lacked. Nutrients that would go towards the Bathochromic Effect.

    Planets further away would possibly have have less toxic and aggressive species of plants that would thrive under reduced direct R & B shift due to the R & B shift being absorbed by other factors as such gas giants and atmospheres such as Earths. Earth would receive reaction light from distant black hole R & B shift and not direct R & B shift from being close to the black hole.
