What I like in Mr. David Butler lectures is that he do not try to be funny or anything, he does science, pure science , lots of it and I have to listen to his lecture a few times to get everything clear. The joy of understanding is my reward.
Normally I get nervous when fans heap praise on a youtuber, but I have no doubt that David Butler is in it for the science and the cosmos, not for the fame
When I was a child in the early 80s we used to get information rich, non patronising science documentaries on the BBC all the time. Nowadays it's all pop science with emphasis on the celebrity, often a scientist, presenting it. Thank goodness for Mr Butler for his scientific content.
These immensely large and minutely small measurements are truly mind boggling... Thank you for helping to bring these concepts to all of us to appreciate.
Im so glad he is still doing well and still uploading. I watch all yt Chanels like royal institute, psb space time, following scientist own yt chanels like Sabine H. Or Brian K... BUT NOTHING COMES CLOSE TO UPLOADS FROM MR BUTLER! THANK YOU SIR!!!!!
Thank you Mr Butler. Life can be stressful sometimes, but the content of your videos and the way you present it relaxes me in a way so i can fall asleep easily. Again, Thank you very much. 💙
Hello Mr. David! I wanted to thank you for continuing to make these videos for such a long time. I have come a long way in my quest to learn more about the universe and I simply wanted to thank you for being a part of my journey and show appreciation for all of your work that we learned from. What started a few years ago with a simple question has now become a lifelong obsession, and I would be grateful to continue learning from your videos for years to come. I hope you are in great health, its been a pleasure seeing your video pop up after a while. My sincerest regards Mr. David!
There of course some thing special When you are teaching, every time I feel it. 100% I can follow deeply and exactly what you are talking about. Never a bit lost! What a great person of science you are!
You're the best Dr. Butler...except "here on Earth" we are actually NOT far from anything that could create ripples in spacetime/gravitational waves. Everytime we simply wave our hand, or a butterfly flutters by...gravitational waves are created. They are just FAR to weak to ever be detected. It's kind of a technicality, but true nonetheless. You're by far my favorite space & physics content tho. May you live long and prosper sir! :-)
Thank you so much for your videos. I felt a rough anxiety as I marveled at how violent it must have seemed to Einstein to think about two supermassive objects rotateing at half the speed of light (or realizing this to be a plausible occurrence). How does our little shoebox garden (solar system) last with such awesome power happening all throughout the cosmos, constantly? Through your videos I find a deep love of the surreal epistemological fugue we live in now, compared to our Greek forefathers and all other thinkers of mankind’s world. Hard to reconcile much in light of such fantastic distances, such behemoth masses, and such terrifying forces. I cannot believe we are close to detecting actual evidence of the big bang. Thank you for giving my mind concepts to wander and wonder in the cosmos. God bless you
David, you do a great job of explaining the intricacies of astrophysics. I'm impressed. You don't treat the topic superficially, but you explain the details quite meticulously. Additionally, you visualize with images and charts, which is very important. This makes me enjoy watching your episodes.
I've been watching your videos for a few years, I love when you post long videos with calm and clear explanations, thank you for taking the time to create them. I admire you a lot. a hug from Brazil.
Thank you so much for making these videos David. I’m certain their impact will trickle down to generations of people who will never see them simply through their influence on so many who are watching now
I seriously love you content man, I just found your channel and I will have enough content to last me the rest of my life. Never stop posting. Each video is seriously golden
David you dont have to redo stuff in better/higer qualliity..your old stuff is still gold...i rather get more stuff from you then you redo stuff...youre awesome and i have learned a lot...all the best from Denmark
"As soon as I released the book.. ..they were discovered!" Hahaha figures right? Thanks so much for adding it. You teach me so much and I'm not even in your class , you da man 💪
General Relativity explains so much: SRely for a start and all its applications, e.g. RedShift and z measurement of galaxies. Then there is bending of light ( Eddington ) Black holes (Chandrashekhar), and now Gravitational Waves predicted by Einstein himself. Other than Newtonian mechanics, EMTheory, The Standard Model, GRely is probably one of the most significant discoveries in mankind's history.
I absolutely love these presentations! Question; at 26:27, "When a gravitational wave passes through the interferometer, and the distance along the arms are shortened and lengthened, causing the beams to be slightly out of sync." Wouldn't the wavelength of light scale up and down with the expansion and contraction of space/time? Or is the expansion and contraction confined to a single axis?
Please come back from your vacation and record more videos. You're the best thing that ever happened to TH-cam😊
Mr. David Butler, you have no idea how much I appreciate your time to make these. I can only express my gratitude for you. Thank you so very much.
I'm always very happy to see a new video for two reasons. I know I'm going to enjoy it, and I'm glad to see he is still posting.
+1
Why wouldn’t he still be posting?
Long live David Butler!
@@kjhmanhe's getting old? He looked very frail a year or two ago but seems to have improved lately.
@@kjhman He has been doing it a long time, and things can change. I wanted to express my appreciation.

I can't thank you enough for this sir.
Cutting edge and insane. Modern science continues to amaze
It must be very satisfying to update the book to account for a breakthrough observation
Mr. Sir! Thank you for making this fun for the kids!
so excited to see a new upload from you sir!!
41:33 Aren't the changes in Earth Rotation, Orbital Motion, disperition delay compared to the change due to the gravitional wave much bigger?
Yes they are. But they are small over the very short time period between pulsar peaks.
David, excellent job on these recent Videos. thanks much! You dig into the details, but explain it pretty succinctly.
Wow, l missed this update what it came out. Can't wait to enjoy it! Thank you for another substantial chapter to this journey!
Always a pleasure watching your videos. The way you explain things and the pictures and diagrams you use are super helpful
Sir David Butler, thank you so much for guiding me to the faraway universe.
I’ve gotta say, this Is very fascinating!
Great production And presentation. Thank you!
Glad to see your posting new content…. I’ve been a huge fan since your first videos!!!!

Wouldn't the wavelength of light scale up and down with the expansion and contraction of space/time? Or is the expansion and contraction confined to a single axis?
The wavelength of the light deviations would be too small to have an impact on the detector.
You are a great educator 👨🏫
