  1. Twinkle twinkle greenish star
    I've always wondered where you are
    Anton says you're everywhere
    But our eyeballs just don't care
    So twinkle red white and blue in our sight
    And let us apes admire the night.

  2. 7:13 "If the snow were yellow it means its mostly emitting yellow light"………no no no Anton,it means don't eat the yellow snow! 😜

  3. Calm down folks. English is not his first language. He could have been referring to mixing colors digitally, not crayons.

  4. I remember reading a page about one of the stars, a moderately bright one but perhaps famous, because it was "the only green one…well [he admitted] greenish-yellow." No I can't remember the name of it. I was just a kid.

  5. Pigments don't work the same as directly emitted EM wavelengths. If you mix all the colors of paint, you get an ugly dark brownish grey.

  6. Hi Anton. The sun should appear light green if our eyes told the truth. However, our sight has evolved so that we see the ambient light as the neutral colour – white. Why? To enhance the accuracy of our colour perception. The brain has evolved to recalibrates the three primary colours by boosting the red and blue to provide an even palette. Otherwise everything would look slightly green.

  7. I am certain that someone already corrected you on this, but it's RYB not RGB. Green is not primary. Thank the geniuses of computing for confusing the masses.

  8. If you're an alien species and you wanted to let everyone know where you are (for some odd and probably unwise reason), just turn your star green artificially. Some type of particulate "halo" should do the job. The entire galaxy, assuming anyone's out there, will (eventually) start looking in your direction.

  9. Very GOOD Mr. Petrov. LEGIT. I definitely understand what you mean about colors mixing and how they can be perceived depending on a person's perception versus their eye's ability to see the various colors (I almost became an artist, then photography and then found out I was color blind when I in elementary and it was validated when I joined the military)– which seems to say that those who can't see all the colors (like myself), could end up missing an event happen because of it. And I swear we're the last generation, as you ended the video stating the "earth is getting hotter". It's definitely said that GOD conquered this world and selected those by who will destroy it, in GOD'S time– accordingly.

  10. Job 6

    6Is tasteless food eaten without salt,
    or is there flavor in the sap of the mallow a ?
    7I refuse to touch it;
    such food makes me ill.
    8“Oh, that I might have my request,
    that God would grant what I hope for,
    9that God would be willing to crush me,
    to let loose his hand and cut off my life!

    Job so your walnut you want to scrape desert waste here

    Galatians 4:30 🕟

    10Then I would still have this consolation—
    my joy in unrelenting pain—
    that I had not denied the words of the Holy One.
