    I’ve not heard the term emission spectrum before today but it isn’t hard to understand what it is if you’re interested in astronomy and science like the two of us are.

    Interesting detail about emitting light when heated, but surely that isn’t particularly common and powerful enough to show the variety of color we see with our white-light sun?

      I don’t know what you’re trying to say or ask anymore. Everything emits light when heated, I’m sure you have an oven, a stove and lightbulbs.

      Someone said the plants around a red dwarf would be red. I sarcastically replied, implying that wasn’t true because most plants aren’t yellow.

      You said the sun isn’t yellow. It is a yellow sun.

        You yourself mentioned the emission spectrum, right?

        I just did some “light” (ha) research, found a random link: https://www2.hao.ucar.edu/education/about-the-sun/what-kind-light-does-sun-emit

        Anyway: The sun doesn’t emit just yellow light, is what I’m saying. So the counter argument about yellow plants just doesn’t hold weight from my understanding.

        The sun is slightly tinted towards the yellow side as viewed from earth perhaps, due to atmospheric scattering, especially Raleigh scattering. But not enough to cause everything to appear yellow. And not because they emit light when heated.

        Not everything is glowing hot just under the sun.

        Is this not a sound argument?

          I don’t know what your argument is anymore. I was arguing that plants growing under a red dwarf wouldn’t necessarily be red.

          Edit: We have a yellow sun.

            My argument is what I wrote, so read that and you’ll know.

            Did you check out the link I sent you? Our sun does not emit only yellow light. You’re thinking of the classification “yellow star”, perhaps. But look at the emission spectrum that you yourself spoke of:

              Maybe go back and re-read my comment and following explanation of why I made my comment. I just told you about emission spectrums, I don’t need it explained back to me.

              Feel free to respond but it feels like I’m talking to a wall here. I’m done.

                Excuse me, but same feeling here.

                You bring up the argument of emission spectrums, and I’m bringing up as a counterargument and using it against your argument, because it makes even more sense in favor of what I’m saying — that our plants wouldn’t look yellow here because the sun doesn’t just emit yellow light. Your very first point just doesn’t make sense. Our sun is a “yellow star” as a classification but it doesn’t emit only yellow light. It emits light filling a spectrum even wider than human vision is able to view. Are you even paying attention and following along your own point? Honestly, my Good Person…

                  And. Neither. Does. A. Red. Dwarf. Emit. Only. Red. Light.

                  It’s like you completely forget the point I was making to go on some tangent. Yes, we have a yellow sun because it turns out the colours we call things are based on how we see. Next up we’ll learn how sounds are described based on how we hear. Wait until you learn about the other senses we use to learn and communicate about our environment.

                  Just like we call plants green.

                    I guess we’ll just agree to agree then. Seems like we’re making the same points in the end.

                    gg, have a good one. 🤝
