Music Free Version - • Gravitational Waves
In this segment of the “How Fast Is It” video book, we cover Gravitational Waves. We examine just what a ‘ripple in space-time’ is. We’ll cover the wave properties and how they contract objects it encounters. We’ll examine binary star systems and the waves they create. This includes the properties of the binary encoded in the created gravitational wave including luminosity distance. We’ll use stars the size and mass of our Sun to calculate the expected amplitude and wavelength magnitudes. We’ll move from normal stars to neutron stars to stellar mass black holes. Along that progression, we’ll see their signature waveforms and build the gravitational wave sensitivity graph. We’ll cover the Hulse-Taylor pulsar (PSR B1913+16) and how it provided indirect evidence for the existence of gravitational waves. We’ll then cover direct detection with Michelson Interferometers. We’ll cover the LIGO technology and sensitivity and then examine the first detection event, and show how it fit the waveform and magnitudes for merging stellar black holes. We’ll include a look at the future of gravitational wave observatories. We’ll finish by covering the nature of gravitational waves created during the Big Bang and how they might be detected today.

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.

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.
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.
The legend finally uploaded
I Love the way You Talk, the way You Look, the way You Teaching Science.
Thank You Just for Being Sir David Butler.
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
YESSSSSSSSSSSSSS
ASTRO GRANDPA IS FINE AND HEALTHY!!!!!!!!!!!!
WE LOVE YOU MAN, THANKS!
David, my wife and I love these videos so much!! Thank you so much for your hard work. God bless.
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.
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.
Can’t wait to watch this after work. Always a good day for video from Mr. Butler 🙂
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
wonderful... thank you sir
Mr. Butler, I adore your videos. I recommend them to everyone I can. I wish I had more than one like/sub to give, thank you so much!
I love this man 😭
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. 💙
Hell yes! A new Dave Butler video
No matter how fast it is, it can’t compete with how fast I’m falling asleep tonight!
😂😂😂😂 same here man..... these videos knock me out flat within minutes... I love them❤
Perfect timing. I'm out on a back injury and love your long form content, especially when i have lots of time to watch it!
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!
I'm so grateful for these videos, sir. It's beautiful.
Thank you for your hard work Mr. Butler!
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.
Thanks love to hear your voice
I really enjoy the information in your videos plus your voice is very relaxing ❤ thank you for your work!
This is great...more please...thank you.😊
Good man Dave!
Finding your channel is truly a gold mine of information and knowledge on astronomy and for that I thank you
Thank you for the time you pour into building these audio books.
Still there watching, learning and thinking.
Take care, much love.❤
Thank you so much for your wonderful productions!! So much appreciated!
just yeasterday was thinking hadnt had a new vid from you in too long. - Nice
Professor Butler's voice is the most relaxing , Thank You
This series does such a wonderful job at explaining “why” all this happens.
Thank you Mr Butler.
Thank you, David.
It must be very satisfying to update the book to account for a breakthrough observation
Another fascinating and informative presentation. Thank you.
Thank you, sir.
Yay new David Butler video! Love this channel
Delighted just by listening his voice
Sir David Butler is living my retirement dream. I wish I would be so chilled and still doing what I love long after retirement age.
I can't thank you enough for this sir.
Thank you for this mesmerizing and fascinating presentation of the material. Absolutely a great achievement.
The Legend Returns.
Fantastic video, thank you for making these!
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'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 sir!
I just love to hear his voice, no matter whether I can understand or not.
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
WOW! You're back! Excellent 👍
Mr. Sir! Thank you for making this fun for the kids!
This is what I live for
He’s not a standard candle but rather a Saganesque candle in the darkness. Thank you for continuing to burn!!!
Mr David good to hear from you again...
Wow, l missed this update what it came out. Can't wait to enjoy it! Thank you for another substantial chapter to this journey!
Sir David Butler, thank you so much for guiding me to the faraway universe.
so excited to see a new upload from you sir!!
Love your videos, David. Thank you for all the great content.
Glad to see your posting new content…. I’ve been a huge fan since your first videos!!!!
Always a pleasure watching your videos. The way you explain things and the pictures and diagrams you use are super helpful
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! :-)
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
Was having a pretty bad time as of late, always happy to see you post.
Legendary content of the most legendary subjects.
I’ve gotta say, this Is very fascinating!
Great production And presentation. Thank you!
Rasclat can die if ya don't know the Butler physics guy, badman for real! Blam Blam, and ting. (and I must add that I found the previous video series very interesting and well thought out - so bravo for being so coherent and mindful in your approach for the layman)
Thank you very much , David!
I love these, thank you so much. I have watched these so many times I have learned a ton!
Thank you for sharing this amazing information David.... we appreciate your work a lot 🎉🎉
Thank you Mr David
The best channel on here
Long time no see! Great to see you´re still releasing more content! Keep it up Professor!
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.
When is this man winning a Nobel?
I'm honestly serious!!!!
Greetings from Sweden 🎉
Lovelies indeed that you are going strong with this channel ❤
Love your work sir, well done
Enjoyed this very much.
"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 💪
That was awesome! Thank you.
You are wonderful, thsnks!
happy for new video. gonna watch asap
Cant wait to watch this tonight
Thx Mr. Butler
a living legend !
Finally my guy is back
Thanks, professor 🍎
You are a great educator 👨🏫
Amazing video!
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.
Thank you
Hi doctor ! Love your videos
Reading is fundamental.
Hi David. Greetings from the UK. I just want to say I appreciate your videos so much, I never saw myself being interested in astronomy or physics but since I found your channel I've got to say I look forward to your next video because I learn so much from you. I just wanted to ask if on future videos, could you please notate which pieces of music you use throughout the video as they are so calm and relaxing, and I'm sure many other people think so too. Thank you again for the videos and I look forward to many more!
The music is identified in the notes below the video.
@@howfarawayisit Hi David, what wud happen to u if u were saying 10 light years away from the 2017 black hole's merging to form the gravitational wave event, move out if 10 light years is way too near? I love the video lectures they are truly educational and interesting to the Nth degree from a fan in Liverpool, England and just to sadly let u no that with the riots in England cuz of. the 3 little girls murdered and we're not all like those far right thugs sorry to even mention it.
Thank you for the teachings, Ms Butler.
Thankyou
What a great day.
Yay!!!!!!!!!!
It makes me so happy that the video with the longest time has the most views , it’s almost like people don’t want short form content anymore. Or they just need a longer video to sleep to 😂 both are fair hahaha
Hello Professor,
An earquake also produces a gravitational wave ever so small; in fact, my ex-wife also produces a gravitational wave when she gets out of bed.
I asked my ex-wife to go on a diet so planet Earth would not go tidally locked to the Sun.
I know more gravitational jokes; but I don't tell anyone because they suck! ;-)
So interesting, only 175k subs,,, and all kinds of nonsesne have over 1 mil, sad world these days. Keep up the great work please Sir.
what exactly are you measuring when science claims to measure gravitational waves? i understand "a wave" but what does that mean lol why are so convinced gravity is/has a wave to detect?
32:46 Mind blown 🤯
