[@Peter_Cordes]

*The "chirp" sound* comes from the black holes spiraling in faster as they get closer. The basic explanation for that isn't much more complicated than a figure skater spinning faster when they pull their arms in. It's pretty amazing how fast a pair of black holes spin around each other when they're getting so close that they put out huge amounts of energy as grav waves (which slows them down even faster until they touch and merge). The closer (and faster) they are, the more they're slowing down (so the faster the pitch changes). That's because the accelerations are higher so more energy is lost from their orbits in the form of gravitational waves. The pitch keeps climbing as they get closer, like a figure skater pulling their arms in to spin faster, or getting close to the middle of a merry-go-round. (But slightly different because the linear velocity is decreasing so I think angular momentum is lost, vs. staying constant for a figure skater.) As the black holes get closer, the force of gravity gets stronger. More centripetal force = faster orbit. That's where the chirp comes from. The sound is from directly translating the gravitational wave amplitude (after noise filtering) to audio. (Or from a clean simulation that fits well with the experimental data.) We're talking about things many times the mass of the Sun moving at a decent fraction of the speed of light. Some interesting Q&As - physics.stackexchange.com/questions/235248/why-is-the-detection-of-gravitational-waves-so-significant one of the answers has diagrams showing the "chirp" in gravitational wave frequency. The first black hole merger that LIGO detected (that Brian is talking about in this old video) converted about 3 solar masses of matter into energy in about 0.2 seconds!!!! That's more power than the rest of the observable universe combined. physics.stackexchange.com/questions/461275/gravitational-waves-and-chirp-waveform physics.stackexchange.com/questions/363306/why-did-the-neutron-star-merger-signal-last-for-so-much-longer-than-the-black-ho Speaking of noise filtering, there's quite a bit of controversy over LIGO and whether they really detected anything, or whether it was just overly optimistic signal processing + randomness! The signals are so weak, even with all the care they take, that it needs a lot of signal processing to pull them out of noise. Pretty much everyone agrees that gravitational waves are a real thing, the question is just whether we can officially say we've actually *proved* they exist by actually detecting them. www.newscientist.com/article/mg24032022-600-exclusive-grave-doubts-over-ligos-discovery-of-gravitational-waves/

You suppose something about me and then stick to it, because you are not interested in a conversation that connects, just punches that connect, for pain is the only thing you feel, but don't want to feel - that is also why, because Trolls are cowards, they want to make others feel the pain. I am not the one attacking other persons as a whole and say to them, that they should kill themselves (your conscience knows what you said to others, no need to prove anything here). There are a lot of trolls in this world and a common denominator of them is that they believe that suicide is not a cowardly and selfish act - maybe that is why they want to force others to do it, like it was with the ancient eye for an eye law back in ancient Greece and ancient Roman's (emperor Nero seems like to be an idol of them - he viewed himself as an artist, which he clearly wasn't). If you were condemned to death and did something dishonorable (like questioning the decision of the emperor or his high status dogs), you could either kill yourself by drinking poison or jump on a sword; or you could watch your family being killed in front of your eyes while being tortured to death.

[@gusstavv]

I'm impressed. Either Stephen got time before the show to chew what they were about to talk, or he is VERY clever since he rephrased some of the explanations and gave intelligent questions, and he even had the time to make some funny stuff while at it... which is not usual on the TV show hosts

[@Wataheadable]

Gusstavv's Stuff Neither of what the professor said or what Stephen asked is considered intelligent. Its just repetition from news articles pretty much, simplified for the general public. If a top level scientist was to explain this new data and theory to another top level scientist, then it probably wouldn't be comprehensible to an average person. Considering that the words that science brings to the "english language" out weighs that of the dictionary, ten-fold. Meaning, you probably wouldn't understand the words because they are Modern scientific words instead of english. Its really like speaking another language.

[@Wataheadable]

Gusstavv's Stuff just saying, whats considered smart to others is ignorance and lesser intelligence to educated others. Neil degreese explained it during some lessons, he said that "we believe chimps have the intelligence of toddlers, yet, if aliens who have harnessed interstellar travel looked at us, they might believe we share the intelligence of their toddlers." ..."it is possible that aliens have reviewed the human race and have already determined that we are not a race that is intelligent enough to contact."

[@Tin9102]

of course he needs to know what they will talk about during the show ... he risks too much otherwise.

[@pochuyma9530]

It is well known in the industry of talk shows that you always prepare ahead of time with the guests. Simply put, bring the guests ahead of schedule to the studio and interview them. After that, you know what topics and jokes work best. Use these on the day the guest shows up for the "actual" interview on TV

[@erhaboriE]

Stephen is a big science nerd

[@gracilism]

This is really a wonderful public service put on by The Late Show. Thank you Stephen Colbert and team.

[@erlindaalba1682]

Just watched netflix blackhole apocalypse, and this is really an awesome discovery. The nobel prize for kip thorne and rei weiss in 2017 are much deserved!

[@ca8rio8ca]

Watching in 2019 and still in awe. Thanks for this Stephen! We need science like this at least once a week on the show.

[@Mattix311]

Fucking LOVE that we are finally talking science on television!

[@KingOfMadCows]

This is a very dense interview but they really kept the momentum going. It was good that Stephen was able to lighten the mood so it wouldn't Bohr the audience. They were both really on the same wavelength, they both Newtons of information, and none of the jokes were forced. Brian Greene may not be a Feynmans celebrity but he was a great guest who radiates intelligence.

[@harmonicpsyche8313]

+KingOfMadCows This comment makes me happy that humanity is a thing that exists

[@gummybear92cjc]

+KingOfMadCows Not that it really 'matters' but I find your 'general' use of physics terms 'relatively' humorous. Your ability is quite 'special'. lol

[@Commentoidiota]

Don't make me love you

+KingOfMadCows I Einstein what you did there...

[@vaibhavgupta20]

[@JohnDoe-re4qy]

Brian Greene and Sean Carroll are easily the best communicators on their field.

[@sphakamisozondi]

Steven u have earned my respect. Your scince questions to Dr Greene were excellent.

[@UpstairsPancake]

Shouting the word "science" at the apparatus is what actually happens in laboratories as a last resort.

"Science better!!"

[@onlyoneearth6773]

This couldn't possibly be more opposite of Fallon. THANK YOU Stephen, for saving late night talk shows.

[@HansLemurson]

This was a great interview and presentation! Approachable and understandable without sacrificing accuracy.

[@exxodas]

Pretty incredible how this guest explained such a complicated topic in a way even kids can understand.

[@aaronrodriguez110]

The idea that scientific discoveries like Gravitational Waves have a place in mass, mainstream media like CBS and Late Night - at least to me - demonstrates that Science is becoming a regular, celebrated aspect of our global Culture. I love that CBS allowed Brian Greene the time to let this be explained and highlighted to the masses.

[@haudace]

i am surprised it took so long... there are many aspects about science that we have been taking for granted for centuries, even though they have completely infused into our lives and we totally depend on them.

[@tedl7538]

Now if it could only become a regular, celebrated aspect of the Drumpf Administration's culture.....that would REALLY be something. Conversely, Obama and his appointees understood the great importance of science to our country and the world.

[@MrMbc77]

These are by far my favorite types of guests on this show. Colbert takes on an entirely new attitude when having such a well spoken and educated guest taking about such an awesome concept, one of seemingly honest interest yet he continues to keep the segment funny.

[@Lasurius]

Man, the ending with Einstein and the ripple effect. A genius little thing. :)

[@AmitDubey-hi2sw]

No kidding this guy is so good at explaining stuff it blew my mind how he explained everything in such a simple way!

[@Rock12402]

This is why Colbert is the best Late Night host. He is bringing science to the masses. Well done sir.

[@scooterdooter]

A devout Catholic who loves and promotes science. Yet another reason to love Stephen Colbert

[@PerseusToons]

AMEN!!

[@bluishwolf]

+NossohSeven It's would be more special if he were Protestant. You know the Catholic church supported heliocentrism?

[@ThexInsidexMan]

+NossohSeven lol catholism is a cult. grow up

[@Tommy-T448]

+bluishwolf The church doesn't support it, but they also don't go against it. Only a small part of the community is a bit extreme. The church has 1 billion follower, so a small part of it is a lot of people.

[@loruma09]

+bluishwolf I believe you're mistaken. Galileo was accused of heresy because he supported Copernicus model (heliocentrism). If I remember correctly, some of Copernicus book's were "indexed" as prohibited by the church. So I would say, the catholic church was not on board with heliocentrism, at that time.

[@oleknoppert2008]

7:29 = the best

[@hansliebe]

I wish I would have found your channel much sooner. I love the scientists/professors/astrophysics majors you bring on your show!

[@insaneapples1559]

Fallon would be like "HAHAHAHAHAHA THATS AWESOME. GRAVITY IS COOL."

[@chrisamalak]

+insaneapples lmaooooooXDXD

[@Dota2funny]

+insaneapples For once i can say that the Host is smarter than me, but Conan is kind of smart too

[@Robstar100]

"SO WHAT YOU'RE SAYING IS THAT GRAVITY AFFECTS STUFF?!?"

[@em3125]

Love how he seems genuinely interested in what the guy is saying

[@Geethasupriyavallivedu2401]

Thanks so much really awesome to see such meaning full and interesting information in a simple explanation

[@jt-qs5en]

This was fascinating, thank you!

[@noxabellus]

Wow kudos to the Late Show for doing this, really great explanation, not dumbed down, not too jokey, but still very entertaining. TV doesn't have to be stupid

[@hoodiesticks]

I appreciate it when Stephen lets the jokes take a backseat to a genuinely interesting subject. That was really cool.

[@yumakid1986]

If we had physics or science teachers like this in every school...passionate about the subject and able to present it in an understandable way...imagine how many more scientists would be inspired in future generations.

[@souvikmukherjee343]

Very very well explained. Thank you Sir

[@MohdAkmalZakiIO]

Ive watched every year interviews like this ft Brian Greene, and everytime an interview session become a Physic class.

[@Ziggyziggy1]

It's truly amazing. We need more of these people to educate us. Even if most of us don't understand all the details of scientific discoveries...

[@MrBlahblam]

It's so fucking great to see stuff like this on the Late Show, the producers are taking the show in a great direction now. It breaks the mold of all the other crap you used to see on late night tv, but it's still entertaining and interesting.

[@Mr_Bob_A_Feet]

Of all the reports I've heard lately on gravitational waves, this for me was the best explanation

[@OHHnoYOUdidntMAN]

I'm glad Stephen Colbert didn't make any crappy jokes during the demonstration and actually was interested in all of this :)

[@deveshverma1666]

very well written lines. I loved it. this is the stuff. thank you Stephen. more please.

[@Zaiqahal]

I'm glad Stephen asks real questions unlike ever other talk show host.

[@danchen3676]

[@harishhg9093]

Amazing explanation...

[@jadeenglene]

I enjoy the science but it also makes me smile of how on the top he feells not only explaining but also instructing the plp behind the scene handleling the illustrations and the light in the room 😊

[@Serpentking789]

I don't know what I was expecting the collision of two black holes to sound like, but it definitely wasn't THAT.

[@Peter_Cordes]

It's pretty amazing how fast a pair of black holes spin around each other when they're getting so close that they put out huge amounts of energy as grav waves (which slows them down even faster until they touch and merge). The close (and faster) they are, the more they're slowing down. That's where the chirp comes from. We're talking about things many times the mass of the Sun moving at a decent fraction of the speed of light.

[@drflash36]

A 'Space fart', eh!

[@Nowhy]

Blackholes colliding? Can we really be sure about that? Can a true scientist, not the false one talking in this show, enlighten me?

[@k7jeb]

This is the actual recording of two neutron stars colliding: kzbin.info/www/bejne/hmPXl5-igrV8nKM

[@jonanddy]

@@Nowhy How is he a false scientist?

[@Prakersh]

The waves are so minuscule that Albert Einstein doubted they could ever be detected.. He would be damn proud ......

[@finleysmurflton4851]

Brings tears of joy

[@ViperXXXXXXX]

True but he also split the atom and created the atom bomb. He said "I don't know what kind of futuristic weapons world war 3 will be fought with, but I know world war 2 will be fought with sticks and stones." Maybe he figured the planet was going to reduce itself to the stone age before we developed this technology. Haha

[@Prakersh]

+Laszlo Vajda You mean the 4th World War ....

[@ViperXXXXXXX]

It's almost three am and I just woke up. My bad.

[@MrHoneHeke]

[@professorboltzmann5709]

This was brilliant. Thank you very much Brian and Stephen!

[@p.f.lagarde3917]

Thank you stephen colbert. More of this

[@DasnarkyRemarky]

This is just great stuff. Stephen was right up there with Prof. Greene throughout the explanation and then the demonstration asking all the smart questions. Prof. Greene was on letterman once, a very long time ago, and the outcome was an interview where Letterman had to resort to bad puns to sidestep his scientific ignorance. No offence to Dave, he was a great interviewer but Stephen's just more cerebral than anyone else in late night television.

[@dreamchasingcat]

Colbert did better than I did in comprehending Professor Greene's explanation, indeed😕

[@summerwarrior458]

Stephen is a good listener. also looks like he did his homework

[@tomschwarz7647]

+DaSnarky Remarky Yeah, I thought that was the best explanation of gravity waves yet, even better than some science channels. It had a demonstration on how it works, you could see how it works, and it was explained in a brilliant, funny and still accurate way (something that is like never achieved). Congrats Colbert.

[@pudgimelon]

+Summer Warrior Yes, he clearly did his homework. That example of using a bomb to map the Earth's interior is a spot-on demonstration of the value of this discovery. I bet a lot of people watching went, "Ah, now I get why this is a big deal." Which is the hallmark of a great interviewer. I really like the intelligent direction Colbert has taken this show. He picks some really interesting guests from a variety of backgrounds. Always interesting to watch and learn. And Colbert plays the role of our proxy very well.

[@bloggs24]

+pudgimelon I think the sad thing about it, is his most boring guests imo have been celebrities, its partly the reason why I've lost a lot of interest in Conan... I dont give 2 shits anymore about the personal lives of celebrities or there movie/book advertisements.

[@pedalpowered1]

I am so glad that Stephen Colbert is using his show to promote Science and a higher understanding. Did you hear that applause when he was announced?? That was BIG

[@justinnahin3960]

Brian - YOU EXPLAINED THIS SO WELL! You spoke slowly and clearly and made millions smarter in a matter of minutes!
