    Some astronomy/physics presentations in RUclips seem too dumbed down as if intended for preschoolers, some are pure hype and obnoxious jargon, intros or bumper music. Even the more academic videos are tedious, filled with math, technical mumbo jumbo or simply unbearably long.
    Then I came across one of your works and, to my surprise, everything I ever wanted in a science video I found it in yours.
    From How Small Is It to How Old Is It and every other video you've posted have been a most valuable tool for the understanding of science for a dumb peeson like myself. Thanx so much, David. Keep it up .

      Yes, but how much better is this than the hundreds of videos where the presenter feels a need to express amazement and excitement, as if the subject needs sensationalising in order to retain our interest? (And to dumb-down the explanation and repeat each part three times.) Just watch it again when your focus is back in alert mode. David, don't change a thing.

    above the stars of God;
    I will sit enthroned on the mount of assembly,
    on the utmost heights of Mount Zaphon. b
    14I will ascend above the tops of the clouds;
    I will make myself like the Most High.”
    15But you are brought down to the realm of the dead,
    to the depths of the pit.
    16Those who see you stare at you,
    they ponder your fate:
    “Is this the man who shook the earth
    and made kingdoms tremble,
    17the man who made the world a wilderness,
    who overthrew its cities
    and would not let his captives go home?”

    This is the video I’ve been looking for recently. I’ve wondered how star formation works. But what I don’t understand is how large the first stars have to be to create these gigantic nebulas. Or were many of these large nebulas created by multiple star explosions? For example 30 Doradus is 1000+ light years across, how can a single star explosion create such a massive nebula like this? And wouldn’t it be forming stars very quickly which would just be colliding all over the place and making more of a mess? Space is such a strange place….

    If u could go at least 180+ thousand miles a SECOND. It would take you a year to get there. That is what a light year means. If the sun turned off like a light switch we would still see the sun for 8 minutes. The sun is miles away. The nearest sun after our sun is light years away. Cars go 70 miles an HOUR. We are quantumly
    Small. And yet so big compared to the very small. Welcome to life and to your everything.💖⭐️☮️🌹. Just think how wild it is that our moon never shows the back side plus it cover our sun perfectly. Stay full of wonder and pass it on if u want to. Rock the space!🌹☮️💜⭐️💚⭐️💜☮️🌹💖🦋
