- Everything you need to know about gravitational waves. In February 2016 scientists announced the first detection of gravitational waves by humans on Earth. This was a huge, world changing, discovery. The gravitational waves were caused by a pair of colliding black holes 1.3 billion light years away 1.3 billion years ago. This video summaries all the of the mind blowing facts about the gravitational waves and describes LIGO, the incredibly sensitive telescope that detected them.

Errata and clarifications.
I endeavour to be as accurate as possible in my videos, but I am human and definitely don’t know everything, so there are sometimes mistakes. Also, because my videos are summaries of some quite complex science, I make simplifications. Some of these are intentional because I don’t have time to go into full detail, but sometimes they are unintentional and here is where I clear them up.
1. I got the month of the original detection wrong! It was September 2015, not November 2015. Silly me, my apologies.
2. “1.3 billion years ago, 1.3 billion light years away” This is incorrect and an oversight on my part. I completely forgot to take into account the expansion of the Universe. The resulting black hole is 1.3 billion light years from us today, but was closer to us when the collision happened, which means that it happened less than 1.3 billion years ago. I tried to work out exactly when but was stumped because I couldn’t find the function for the acceleration of the expansion of the universe. The redshift of the signal from the black holes was about 10%, so I thought the collision was 10% closer in time than 1.3 billion years i.e. 1.18 billion years, but I think it might be a bit more complicated than that.
3. LIGO schematic animation. I made a couple of silly errors here. The first circular mirror that the laser hits should be 90º to the way I oriented it: half the laser light is transmitted and half reflected, each one going up a different arm.
4. LIGO schematic animation. When the laser bounced back and forth it should bounce between the two suspended mirrors and not go all the way back to the diagonal mirror.
5. VIRGO is near Pisa, not at Trento as I drew on the map. I said the right thing but drew the wrong thing. My apologies.
6. ‘A second even more powerful collision.” Wrong again! The second collision was less powerful and the signal was more buried in the noise.
I’m not happy with the number of flat out mistakes I made on this one! I will try better in the future. I blame it on the Christmas spirits.

this is by far the best explanation i have seen so far on the topic.. very well done..
Mikael Wendt 😢i want education i am hurt i want to goe to university yeah 😭hello give me good explanation ?47584554(╥╯θ╰╥)３２５７８５６=

Please do videos about
1. String theory
2. Loop quantum gravity
3. Dark energy and matter
4. Things like do you believe the unuverse is expanding in an accelerating speed/ decelerating speed/it gets pulled back by it's own gravity?
Please reply if you see this, THANKS!
What about some innovative idea???
Nice suggestion!
If you want videos like that check out PSB space time
Not sponsors
Astrophysicists have only one tool in their kit-the hammer of gravitational theory. To them everything is Mass.
yeah, they are all awesome topics!!!
These are some fantastic visualizations. Great video!
Yes, they are representative visualizations, not real observations. Keep your pseudo-science out of science.
cant disagree
Dominic. I discovered your channel 10mins ago. I love your video. I will definetly support you on patron. I wish you the best for making us realise how exiting our situation is!!
Thanks so much man! :D
Willie Combs the pendulum no?
Willie Combs first of all the spinning of the earth doesn't do anything cuz it isn't accelerating therefore the measurements taken in our reference frame are just as valid as those taken in a "stationary" reference frame
Willie Combs the pendulums don't defy physics they act as insulation from any perturbations
Willie Combs and for the expansion and contraction of earth, I'm going to assume you mean plate tectonics. And if u did some research you would see that ligo was built in geographically inactive regions. Fite me (lol jk)
So that's what it sounds like when two massive black holes collided huh? Bwoop!
After a measly 1.3 BILLION years of elongation and reduction in energy. Nothing much. BWWWWOOOOOP!
ScutFarcus That's not actually how they sound. Because there was no sound there. This is just converted into sound waves, it's more like an artist's rendition. Not the real thing. If you were even hundred light years closer to that, it'd have ripped every single molecule in your body apart.
I am just asking, but if so ("it'd have ripped every single molecule in your body apart"), why didn't this wave destroy other celestial bodies on its way to us? Wouldn't we be able to observe them by now? (Sorry for bad English, I am not native)
@@thatmomentwhen9718 well if they got turned into space dust there is no real way for us to discover them
2019 here
Black hole photograph is out
Nice
Having great knowledge on some topic and being able to explain it exceptionally well is a different thing. Very few can do it like you. Thanks!
Great video, really well explained! Your animation system is fantastic. That last zoom out at the end made me wonder if you'd make your final image available on flickr or something like you did with the map of physics? And I'm defninitely in favour of a map of mathematics video too :)
The two animation videos that you made are really very well done. As someone who is interested in astophysics but too lazy to read articles, I will definitely say that this is by far one of the best productions on CZcams that I have seen. You should definitely keep this up! And please make the map of mathematics, I will be looking forward to it.
the way you explain and illustrate all these things is just amazing, please make more of these animation videos :D
Amazing video, keep this up! :) your editing is becoming really great as well.
I've missed this channel. Already loving your stuff! Thanks
WOW!!!
Loved your video , just like the last one. Keep on doing this kind of material. Its beautiful.
Super informative and very well explained!! The animations are on point! Keep them coming :)
Absolutely a top notch production. Thank you, very well done.
Thanks for the great videos, and also for being transparent about errors & for following up. Keep up the good work!
Awesome videos Dominic!
I really love the way you explain these things in combination with your animations! :)
Hi Dominic, amazing video! love the animation style and the way you make some subjects like this comprehensible. I really love physics but I have trouble understanding them. Hope to see more of videos like this in the future :)
Thanks much for this - very good explanation, great visualizations. Great job.
This video is so well done and the subject is so mind blowing. The possibilities are so exciting. I actually welled up a little bit with emotion. Well done!
This is simply amazing! how can you dislike this??!? Please never stop these videos. EXPLAIN TO ME EVERYTHING!

It's amazing how you manage to order the information, it's really useful, please keep doing this kind of videos they are a great help for understanding all sorts of things
Thanks from Chile :)
Great job again 👍 You are explaining these complex things in just few minutes. I have understood your efforts and time in making these videos. Please try to post one video a month. That will be really great stuff for us. Finally, as usual Fabulous Work 👌
Great job on explanation and visuals. Can't wait to see more.
Such an amazing video, you deserve much more views
Keep making those videos. Very nice work. Thank you
This is amazing! A small Channel really worth supporting
Amazing content, keep up with the good work and I'm sure your channel will grow fast.
Greetings from Poland.
Excellent video in addition to your Subject Mapping videos. Being able to visualize these otherwise complex ideas is a fantastic opportunity for the intellectually curious and for anyone approaching the subjects from an accessible perspective or for a first time introduction. Thank You!
I've been watching tons of your videos! I'm completely amazed! Thanks a lot!
Its crazy how good you are in explaining this....
I was literally nearly to cry because it’s so fascinating
Great job, enjoying the videos. A request: please create a playlist for the early lecture series you posted on quantum annealers; these make it easy to watch the videos in a series in proper order. Thanks and again well done!
Great job - I bet they're a lot more work but the animated videos are a *huge* step up in engagement for me as a viewer. Subscribed.
Man, that's incredible how you explained this. I was always amused by gravitational waves, but I never understood completly. Now I do, at least the basics and how it works and why it exist. Thanks and I hope you to make more videos like this.
The best simple comprehensive explanation. Kudos to the great work.
Great job Dominic i hope to see more of ur vids!
this is really good. it's simple and clear and elegant. i really love your videos
Such a cool story and exciting discovery. Funny that you drew little highlights on the black holes though :) Can't wait for all the neat stuff to come out of this new tool.
straight away subscribed...excellent way of explaining
Keep doing videos like this and the physics map ! They are amazing !
keep it up! absolutely blown away.
Very nicely explained. Keep it up. Keep posting more video. Thanks
great way of explaining with the help of your way of animation .... it helps me remember for a longer time
omg Dominic i love science even more now because of you.. AMAZING honestly
Amazing video. Love the style!
best video on gravitational wave, I have seen. great work.
Loved your videos (binge watching right now).
This was awesome! Please make more
Great videos Dominic.I just found your channel and I already subscribed it.Some much valuable stuff covered in such short time with great illustrations..Simply my dream explanation videos.
Duuuuude I can't believe it's been almost 2yrs since they detected gravitational waves! I remember hearing about it as if it was yesterday. I had no idea that the LIGO detectors had been turned on just 2 days before they received their first signal. Amazing. Another awesome video, Dominic. Can't wait for the next one!
Great video! i loved the map of physics and this one, thanks alot for this awesome and illustrative videos. another fan!!
Hey, that was an amazing video! Greetings from Brazil, continue with this excelent job.
more vids like this an the last one please, amazing so educational!
you seem to put a lot of effort in your videos, keep it up!!!!
Awesome dude, keep them coming :)
Thank you so much , this made me tear up a bit 😅 really appreciate this video.
Very informative, your videos are amazing! Thank you so much for these quality videos.
Thank you for telling us about Gravitational Waves :3 impressive insight
This channel makes me like physics, I couldn't understand physics in my school, but from this video, I became more excited for learning physics. Thank you so much!
Very nice. You look like a sympathetic guy with very good voice. Plus that visualization. Just great job man. Keep continue with that. Thumbs up
Thank you! Cant wait for more videos. Would love some videos discussing parts of the theory of relativity, have watched countless hours of video on that subject and still feel like I have a rudimentary understanding at best
The best explanation of gravitational waves to date!
Thank you so much for making these videos! I'm a visual leaner and you made some many things click that four years in college failed to connect. thank you, i've really enjoyed your maps.
Amazing....So captivating, Good Work!!!
This is a great video! Great animation and aesthetic.
I love this format.
very, VERY good video. subscribed!
Thank you for the production of this film. I, a physics graduate some 40 years ago and then never toughed it again, do enjoy watching the film and find it very easy to understand which has raised my interests again. I was very interested in special and general relativity as well as quantum mechanics during my study time. Hope you can produce more short films on these two very interesting subjects.
Brilliant, simple explanations. Subscribed
Very cool stuff. Subscribed.
absolutely love your out of this world quality content
😍 I am listening to this at work, and the music was a big help in visualizing gravitational waves! The music also helped make this video cool 😎. Fantastic video, much appreciated!
thanks for the video. keep going and make more of these amazing videos.
I absolutely love this video. very original form of explaination with this and the physics map
please make more videos this way
Great video man. Love your content. Greeting from Mexico :)
thanks so much for making this.
You explain concepts absolutely brilliantly, and the effort put into visualization is definitely noticeable, please continue to make more videos. Do you by any chance teach mathematics or plan on doing any maths videos?
Dominic, you’re a story teller of these incredible discoveries for us less than genius minds. Thanks.
Amazing video! Very easy to understand. Thank you!
very good video, keep on making great science videos
Hello Sir,
I just wanted to say that your explanations are very great and I would love to see many more of them.
