Thank you Mr. Butler. I love these video series. Very easy to understand and not full of BS filler talk or in video sponsor ads pleading for me to sign up for some expensive "make you smarter" web site, nor does it have obnoxious video opening or closing sequences.

Yep

[@Scott-eo7lj]

Every night.

[@rogerstone3068]

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.

How does your channel only have 75kish subs? This is some of the best educational information on Astronomy/Physics out there. Your work is phenomenal. I wish this was around when I was a student.

[@DyingToLive12]

Because only 75kish people subbed. each sub counts as 1, so 75kish equals 75kish subs. hope this helps.

I love your presentation. I love that each series has the HOW title, reminds me of old educational books i had as a kid. In fact you bring back a wonderful youthful feeling of a hungry mind.

[@catschase247]

Some astronomy/physics presentations in KZbin 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 .

Whenever completing a David Butler video, no matter the outside temperature, as long as the sky is clear, I just go outside with my large binoculars and my 8" telescope, and enjoy the stars. That explains the frostbite, every Winter.

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!🌹☮️💜⭐️💚⭐️💜☮️🌹💖🦋

[@alexburke1899]

Yeah when I really need to stop feeling sorry for myself I often listen to world war 2 audiobooks. It’s kind of a form of cognitive behavior therapy to give you perspective. Cosmology and astrophysics are obviously good for shifting your perspective too so good point. Hope you are doing well depression can be very difficult as you know, I struggle with it myself.

[@ResourcefulNomad]

David, you present the subject in an easy to understand way for the lay person with cultural references and music selections that add to the enjoyment of your lectures. I’m taking a college level course that assumes an intelligent audience with a basic grasp of science and culture in general. Thank you.

[@dino575]

Loving your videos - beats the now chronic discovery channel :) thank you ! )

[@vermili0n]

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….

[@howfarawayisit]

It takes lots of stars making lots of dust over lots of time to form a nebula like this one.

What causes a supernova fragment like IC443 to be so asymmetric? It seems as if the supernova blew off material to one side.

[@randjooe72]

The big difference between this program (and all similar programs) and the 'biggest baddest sieve' you could find. The sieve would hold a gazillion times more 'water'. I keep hearing words i.e. big bang, particle clouds, hydrogen, helium, nitrogen..... etc. The FIRST and most important law of chemistry is"Matter Can Neither Be Created or Destroyed"!! So; if the big bang really truly happened and the trillions & trillions of tons of matter that was compressed into that tiny speck of matter: WHERE'D IT ALL COME FROM? WHO MADE OR DESIGNED IT? if we had a chance to visit the most modern, the most intelligent Lab in the world and saw the fastest most intelligent computer in the world. We ask the scientist, "When did computer arrive at your facility and how did you arrange for such a complex piece of equipment and how much Did it cost." The question we WOULD NOT ASK, " When did this computer just come into being and how many millions of years did it take to evolve from a pebble!!😂 AWFULLY SILLY of me to suggest that any kind of instrument or device could simply evolve from a pebble. Don't we Agree on that point? INTELLIGENT DESIGN WAS THE ONLY FACTOR in the creation of LIFE & MAN. There is a GOD IN HEAVEN and he is coming back SOON, VERY VERY SOON. He will have an 'attitude' against ALL who have rejected his Only Begotten Son - JESUS CHRIST. God will judge and CAST all who have REJECTED JESUS CHRIST, into the Eternal Lake of Fire. All the details are in a copy of the. KJV BIBLE or at a local, Bible Believing Church. The only person's headed to eternal damnation are those who choose to reject JESUS CHRIST. The choice is YOURS: CHOOSE WISELY. Hell is forever and so is Heaven.

Isaiah 14 13You said in your heart, “I will ascend to the heavens; I will raise my throne 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?”
