On Thursday, February 11, 2016, the National Science Foundation made a thrilling announcement: gravitational waves-first predicted by Einstein as part of his general theory of relativity in 1916-had been detected for the first time. This incredible development made front page news and was reported by outlets across the country. How was such a remarkable discovery, a long hundred years after Einstein’s prediction, made possible?
In this Science Salon based on her new book, Black Hole Blues and Other Songs from Outer Space, astrophysicist and award-winning writer Dr. Janna Levin tells the epic story of the scientific campaign to record these waves-the holy grail of modern cosmology. A handful of physicists, led by Kip Thorne and Ronald Drever at Caltech and Rainer Weiss at MIT, have been working nearly their entire careers to conceive of, design, and build an instrument sensitive enough to detect gravitational waves. Levin delves into the lives and fates of the scientists, painting compelling portraits of these very human visionaries. She journeys from Los Angeles to Boston, to the LIGO interferometers in Hanford, Washington and Livingston, Louisiana, to the labs, offices, and observatories where the work in this great quest has painstakingly unfolded over the past five decades. Her account of the personalities, surprises, setbacks, and successes is a compelling and intimate portrait of the people and processes of modern science.

I can listen to her speak all day..
i have done.
I’d love to be in Janna’s class as her student. She reminds me of lecturers that get you attached to a field of study in a really studious and interested way, constantly inspiring. I believe this is exactly what Janna was placed here to do and it’s great to share this universe with people like her.
wow shes amazing, my intuition is bending left & right .I have to rethink everything
very good INTERACTION...thanks a ton..really appreciated
I have enjoyed all these, but this one is the best one so far.
I recall a saying that realization comes two years too late. :(
it is 3/11/18 today, thank you for being here Dr. . Your conversation is clear .
I love cosmology. I love it even more now.
Really impressive physicist. Thrilled our society has the capacity to have great individuals look into these fundamental questions. Makes me wish I could go back in time :) and explore more with professionals like this. Funny how such a low key, great mind can potentially have a much, much larger effect on society/humanity in the long run than any CEO IMHO.
Among working physicists, Janna Levin is one of the best science communicators out there, on par with the likes of Sean Carroll.
BL1 covering for the fake moon landing
superb content!............love that lady physicist !
As a theist, I really appreciate what she says about "God of the gaps" (45:35). Theists don't have to (and should not) argue from gaps. We can argue for God based on what we KNOW, not on what we don't know. The Fine Tuning of the constants that have been discovered and affirmed have philosophical ramifications that is good evidence for theism.
oh don't. That argument really bugs me. I will give it more credibility if you can come up with a universe producing mechanism used by Gods that would neccesarily require the universe to be the way that it is, and not one of the near infinite other possible universes that could have been created. You cant stack the decks like that
Troll. Did you even hear what she said? Fine tuning is Teleological. It's essentially god-of-the-gaps. "Don't know why all this shit lines up so perfect? Must be god."
Not a bad book.Perfect for people interested in Astronomy.
+sava pavlovic (savpin) Like meh.
Dr. Janna, the bold new face of brains and beauty that illuminates the intellect with thought provoking soft large brown eyes. First among equalls, you are a super nova of magnificent mentality.
the LHC did create black holes, but as janna said they were so small they "lived" for tiny fractions of a second. having already travelled in time and watched videos of jannas from 2019 (!) we now know that gravitational waves do warp space / time and colliding black holes made the noise. time travel is wonderful. how big are those mirrors, the hand gestures imply they are big, but surely they only need to be, well less than inches or millimeters given they measure lasers? at 54:10 talking about turing and being machines, and the soul, the "joyous" experience is a combination of things, learning from our parents how to "be happy", the program in our brain that "feels" happiness and chemicals released, so, surely this could be duplicated in AI. brian greene says that it's not so much AI we should worry about, but whoever is in second place for the race to create AI, they could be really pissed. and what does it matter (!) if AI do succeed us, we are all going to die and pass things on to our children, or other people's children, and AI will only be another form of human, so what matters it if future humans are machines rather than biology?
Dr. Levin is awesome
BAI q
Great talk. Loved it.
I love this Janna......
I LOVE YOU JANNA LEVIN-.
WOW! I never knew Mariah Carey was so smart.
probably cos you only watch her music videos :)
coolal19 Just a parrot.
1:26:10 how can andromeda be thousand times bigger than milky way?
Why not...?
Love your area of work.
Excellent observation and a good writer.
What is inside a black hole is a huge dense material and the event horizon keeps on shrinking as mass increases when two of them join and at one point the light enters the dense material and spark ignites the material.
Dimensionality and other sense work only within a specific constraints. Defining dimensions is a rough idea how is visualizations perceived
Relativity is somewhat explained in a specific set of definition.
Depends on how one defines 'free will'.. if it's you weigh logic in your decision, but you are also influenced by varying degrees of emotion.. then I think we have some free will, but probably less than we think.
I checked into space expansion the other day and was surprised to find that it expands at 16 million miles per day, which is more than thought. The expansion rate is increasing so it's maybe not surprising after all. So come on alien fans, they are getting away rapidly! What are you going to do?
There are different types of black holes that is difficult to explain. Dark matter is an other difficult kinds of matter which are supposed to start with a spectrum of microwave radiation range and extend beyond. Black holes are just the beginning.
Our universe is actually the result of a super massive black hole reaching its limit of mass. Once it grew big enough, it finally exploded like a balloon that is overfilled with air or water. Since the extreme gravity breaks all the heavy elements back into the simplest form, which is protons and electrons, the new universe started back out with hydrogen.
Good Value
The dimensionality changes as we go further into numbers or space. like one is a container every other containers. 2×2 or 4 is a container of one two and three with a spacial surface dimension of two. so light has seven colors which means it can exist only in a spacial dimension of 2×2×2 or two cube which is the minimum even number of two. And a three dimensional object. But light exist in higher dimensions in a different form.
they are just the limiting factors of spacial dimensions.
Free space one two.
Two three space time curvature fabrics. 4 5 6 event horizon in between. 6 7 ripples or spin or twist.
WOW!
The interviewer reminds me of Sir Anthony Hopkins.
Look carefully dude from Breaking Bad and Better Call Saul is sitting at the back of the audience.
You misspelt her name
+RoM1il Thanks for the heads up :)
Skeptic Magazine np
ocean water doesnt curve at all for thousands of miles
surely Andromeda can't be a thousand times bigger than the milky Way. I've heard various conflicting figures, but that is just out of the ball park compared to anything else i ever heard
look it up, it aint rocket science, why believe voices when you can find out from you know, a book or two. sheesh.
Since the 'gravity wave' traveled at the speed of light between the two stations, it cannot have been gravity -- if gravity was as slow as light speed, our solar system would have flown apart a long time ago. This is not actually arguable. IMO.
Eh..????
(1:26:10) "Andromeda 1000x bigger than our galaxy". Really?
Can someone point me to a paper or something, which supports the idea of photons crushing into a black hole, create a big bang inside the 'universe' created by the black hole itself?
BH just a different type of star, it can't create a universe.
Ok, since nobody is asking, I will. Does the gravity "wave-form" have a corresponding "Graviton" particle-form? Inquiring minds want to know!!!! I have a paper on it. Everything is riding on it. My future nobel nomination. Please respond Dr. (Janna). Is it a quantum size particle? How would you detect it? Some dude asked about gravity wave reflection/refraction.... and would that refraction (presumably from something infinitely massive- as in another blackhole) be the same as implying gravity waves would have interference as well? Please help, my brain is exploding.
Just like light has a particle aka the Photon so yes..We have managed to detect the particle form of mass the Higgs Boson yet it is the Higgs field that gives mass or the Higgs mechanism..If you think of it in String Theory terms the particle is just a tiny vibration of the field call it a by product..This will take longer to explain
A black hole is the largest prime number of power twelve to base ten.
Awesome guest speaker, as usual for this channel, thank you. Only thing that got on my nerves is this fellow in the front row (asked the first question); why is he wearing a hat indoors? Not only is he inside, but he is in the presence of women (including, but not limited to the guest speaker). It seems odd because, the folks who can afford these wonderful events, should have better manners than that and follow proper hat etiquette.
The mere idea of etiquette and wearing what you're supposed to wear instead of wearing whatever the fuck you feel like wearing wherever the fuck you want is disgusting. And why the presence of women should affect that notion in any way, I don't know. Hopefully we'll soon become a species that doesn't judge based on such irrelevant nonsense.
Ezequiel Iglesias Oh, brother. No worries, you can pull the undies out of your cheeks. It was only an observation. Obviously, these good folks have no problem with it, and your species is on the right track.
Etiquette aside, his Andy Capp was blocking the two-shot. Those two knees.
Why did you have to point this out?! Now I can't stop watching it bob around.
Seriously the camera operator should have taken care of this during setup. "Back up, doofus!"
Maybe he's bald on top and insecure. Or maybe he's a deush
Aubrey plaza's sister?
I'm afraid that we'll never know the ultimate truth.
Imagine, my generation used to say Clapton is God...
At least with Mayall and Cream.
I always refuted it. I was a non believer. ;)
Big Bang is an imaginary picture of the image projection drawing, continuous creation connection in Principle that is mapping the observable positioning of time duration timing modulation, ..composed of the assembled abstractions of cosmological measurements.
Evolution is the glitch we have to have, in the actual cause-effect of self-defining time duration timing probability integration.
Definition of the terminology is the job of Theories that are never going to have the finality implied by an Absolute Being, if continuous creation connection is the Spinfoam Totality Principle that is Universal Holographic Black Hole Singularity, Actuality.
Standing waves are composed of Spin. Etc, fun to imagine...
Time-Timing "Tweak" = e-Pi-i interference positioning, resonance of Spacetime-conduction or cause-effect of zero-infinity difference distribution singularity projection drawing of time duration timing modulation.
E-M waves are "electronic" FM-AM radiation-projection.., Gravity waves are mass-momentum E=mC² format of combined "neutral" neutronic radiation of flat space ground statof Superconductivity relationships.., Reciproction in continuous creation connection Principle. If hyperfluid superspin potential possibilities being projected and drawn by self-defining interference cause-effect is Super-Natural manifestation of quantization probabilities in potential possibilities.., calling this Principle "God" seems inadequate to the meaning of the Holographic universeal communication mechanism of QM-TIMESPACE Actuality here-now-forever cause-effect existence. (No gaps, no-thing empty, just orthogonality In-form-ation timing connection rates aka Calculus..)
Max Tegmark is absolutely correct, of course. Time Timing is Mathematical Calculus/Universe.., in Principle. (If you know "philosophically" what the identification nomenclature means, the whole message Hologram)
Free will equivalent is observable inherent Quantum Dualism, and the potential possibilities Operator. (?)
Is the Empathy required for Teaching the real Telepathy?
If Big Bang, the Titled word for the general meaning of universal wave-package event, then it's Real Meaning is the function e-Pi-i interference positioning resonance Picture. Cumbersome and unnecessarily confusing language..
How about AdS/CFT Spinfoam fractal bubble Totality "balloons" of Quantum Operator Fields Modulation Mechanism Mathematics..? Field line topology.
It pays to conform in the not even wrong principle of accepting status quo+/- polarization? Individually, not collectively, together we all fail.
I not kinding you want a read spar cmp
TE A6O.
I love her, "I don't talk about gender in science, lets talk about the science"
Am I too old to have a new web crush?
The moment that really sealed it: "Shut up," she explained, in response to the question about being A Woman In Science.
Wilson Mark Rodriguez Lisa Jackson Matthew
you so beautiful
no, im not offended because christ created everything .
Fix. Thi bufing now you go to the black how we can't get a good countus on the plants fik this or I grab some ting of the 13 the read how like CMP or spaer and lazre fix ineat you still have your soul don't have any
hahaha, intelligent scientist, she doesn't like people to figure out her age, so she prevents him to tell her graduation years.
إجابات عن تساؤلات علماء وكالة الفضاء الامريكيه ناسا. حول : شكل الكون ؟ - الكون يتسع إلى أين ؟ - طبيعة الثقوب السوداء ؟ - نهاية الكون ؟
يجيبها : دكتور / فريد هراس رئيس بحوث متفرغ بمعهد بحوث وقاية النباتات - الدقى - القاهره
أولا : بداية الكون - شكل الكون .
It is presently an unsolved question whether our universe contains closed, flat or open spatial three-geometries.
يقول تعالى : هُوَ الَّذِي خَلَقَ لَكُمْ مَا فِي الأَرْضِ جَمِيعاً ثُمَّ اسْتَوَى إِلَى السَّمَاءِ فَسَوَّاهُنَّ سَبْعَ سَمَاوَاتٍ وَهُوَ بِكُلِّ شَيْءٍ عَلِيمٌ ( البقرة:29 )
يقول تعالى: وَمَا قَدَرُوا اللَّهَ حَقَّ قَدْرِهِ وَالْأَرْضُ جَمِيعًا قَبْضَتُهُ يَوْمَ الْقِيَامَةِ وَالسَّمَاوَاتُ مَطْوِيَّاتٌ بِيَمِينِهِ ﴿ سورة الزمر: ٦٧﴾
يقول تعالى: إذَا السَّمَاء انشَقَّتْ (1) وَأَذِنَتْ لِرَبِّهَا وَحُقَّتْ (2) وَإِذَا الْأَرْضُ مُدَّتْ (3) وَأَلْقَتْ مَا فِيهَا وَتَخَلَّتْ (4) وَأَذِنَتْ لِرَبِّهَا وَحُقَّتْ. سورة الانشقاق (5)
يقول تعالى : إِنَّا زَيَّنَّا السَّمَاءَ الدُّنْيَا بِزِينَةٍ الْكَوَاكِبِ ﴿ سورة الصافات : ٦﴾
يقول تعالى : وَلَقَدْ زَيَّنَّا السَّمَاء الدُّنْيَا بِمَصَابِيحَ ( سورة الملك - الآية 5 )
يقول تعالى : أَوَلَمْ يَرَ الَّذِينَ كَفَرُوا أَنَّ السَّمَاوَاتِ وَالْأَرْضَ كَانَتَا رَتْقًا فَفَتَقْنَاهُمَا ) الانبياء: 31 (
يقول تعالى : ( اللَّهُ الَّذِي خَلَقَ سَبْعَ سَمَاوَاتٍ وَمِنَ الْأَرْضِ مِثْلَهُنَّ سورة الطلاق ( 12 )
يقول تعالى : ﴿وَبَنَيْنَا فَوْقَكُمْ سَبْعاً شِدَاداً﴾[النبأ: 12 )
يقول تعالى: اللّهُ الَّذِي رَفَعَ السَّمَاوَاتِ بِغَيْرِ عَمَدٍ (الرعد:2). خَلَقَ السَّمَاوَاتِ بِغَيْرِ عَمَدٍ (لقمان:10 )
يقول تعالى : ﴿ يَوْمَ نَطْوِي السَّمَاء كَطَيِّ السِّجِلِّ لِلْكُتُبِ ﴾ (الأنبياء:104).
وهذه الايات تشير الي :
خلق الله تعالى الكواكب و النجوم تسبح فى الفضاء العظيم داخل كره و جدار هذه الكره يسميه الله تعالى ( الارض جميعا) و هو الذى يقول عنه تبارك و تعالى : الارض جميعا قبضته يوم القيامه بينما جميع الكواكب داخل الكره فهى اراض مثل الارض التى نعيش عليها و هى كوكب الارض و هى ذره من الكواكب التى توجد فى الكون كما يوجد العدد العظيم من النجوم مثل الشمس داخل الكره العظيمه ،
بعد أن فرغ الله تعالى من خلق ما فى الارض جميعا (جدار الكره) من كواكب ونجوم قام سبحانه و تعالى بفتق جدار الكره الى سبع طبقات متوازيه و خلق بينها الفضاء المفرغ الذى لا يحتوى على شئ و هذه الطبقات السبعه هى السماوات السبع و أصبحت كل سماء هى بمثابة أرض للسماء التى فوقها .
نتيجة وجود هذه الطبقات المتوازيه ووجود الفضاء المفرغ بينها ينشأعن ذلك قوة رفع ( و هو ما يطلق عليه فى الطبيعه إصطلاح ..... تقوم برفع الكره بطبقات جدارها السبعه أى الارض و السماوات السبع فى الفضاء بغير عمد
و أصبح شكل الكون كالتالى : سبع كرات متداخله كره داخليه اولى تحتوى بداخلها على الكواكب و النجوم و هذه الكره داخل كره ثانيه بينهما فضاء مفرغ من الماده و الكره الثانيه داخل كره ثالثه بينهما فضاء مفرغ من الماده و هكذا حتى الكره السابعه ....................................... و هكذا يتواجد لدينا السماوات السبع و الاراضين السبع فى الفضاء بين ارض غير الارض و سماوات غير السماوات ، و سبحان الله العظيم مع كل هذا الخلق العظيم فقد وسع كرسيه السماوات و الأرض .
ثانيا : الكون يتسع إلى أين ؟
What space is the universe expanding into?
يقول تعالى: فَلا أُقْسِمُ بِمَوَاقِعِ النُّجُومِ وَإِنَّهُ لَقَسَمٌ لَوْ تَعْلَمُونَ عَظِيمٌ (الواقعة:75،76
يقول تعالى: ﴿وَالسَّمَاء بَنَيْنَاهَا بِأَيْدٍ وَإِنَّا لَمُوسِعُونَ﴾[الذاريات: 47]
وهذه الايات تشير الي :
خلق الله تعالى العدد الهائل من المصابيح ( النجوم مثل الشمس) داخل الكره الداخلية الاولى فقط و هى السماء الدنيا ، ووقود هذه المصابيح هو تفاعلات نوويه ينشأ عنها إنطلاق كميات هائله من الطاقة ويتبع ذلك إزدياد الضغط داخل الكره و يتمدد جدار الكره و يتسع الكون
ثالثا : طبيعة الثقوب السوداء ؟,(Black Holes)
Today there is almost universal agreement that black holes exist, though their exact nature is still in question.
يقول تعالى : أَفَلَمْ يَنظُرُوا إِلَى السَّمَاء فَوْقَهُمْ كَيْفَ بَنَيْنَاهَا وَزَيَّنَّاهَا وَمَا لَهَا مِن فُرُوجٍ (سورة ق:6 )
يقول تعالى: فَلاَ أُقْسِمُ بِالْخُنَّسِ . الجَوَارِ الكُنَّسِ (التكوير:15- 16.)
وهذه الايات تشير الي :
أفلم ينظروا إلى السماء فوقهم كيف بنيناها وزيناها وما لها من فروج ,شرح ما لها من فروج هو ما بها من فتحات والتي يمكن تسميتها باسم الفتحات الخانسة الكانسة ( الثقوب السوداء ) الثقوب السود (: Black Holes
بعد أن خلق الله تعالى الكواكب و النجوم داخل جدار الكره ( الارض جميعا ) ثم فتق الله تعالى هذا الجدار الى سبعة أغلفه هى السماوات السبع و أصبح لدينا سبع كرات متداخله ، الكره الداخليه الاولى هى الوحيده التى تحتوى بداخلها على الكواكب و النجوم و داخل النجوم تحدث التفاعلات النوويه التى تطلق كميات هائله من الطاقة فيزداد الضغط كثيرا داخل الكرة الداخلية الاولى عن الضغط خارجه فتخرج المواد ( مجرات سماويه مختلفه من كواكب و نجوم ) بمجرد الاقتراب من هذه الفتحات و تخرج بسرعات هائله ترتفع درجة حرارتها خلالها الى ملايين الدرجات و يتحول اجزاء من كتلتها الى طاقه فيتم رصد الاشعة السينيه غير الاعتياديه على سطح الارض كما يختفى منظور النجوم عن سطح الارض و هذا الرصد و إختفاء المنظور هما الطريقان اللذان يستدل بهما على وجود هذه الثقوب السوداء ( الفتحات فى جدار السماء) ، مع توالى خروج هذه الاجرام السماويه من الثقوب السود الى جو السماء الثانيه حيث الفضاء المفرغ ( (vacuum الذى لا يحتوى على مواد يتبع ذلك حدوث تغيرات ( vacuum fluctuations ) بين طبقات السماوات ينشأ عنها قوة رفع للسماوات بغير عمد فسبحان الذى خلق السماوات و الارض و ما بينهما و رفع السماء بغير عمد ..................
رابعا : نهاية الكون ؟
The ultimate fate of the universe is a topic in physical cosmology. Many possible fates are predicted by rival scientific theories, including futures of both finite and infinite duration.
يقول تعالى: فَإِذَا النُّجُومُ طُمِسَتْ ( المرسلات: 8.)
يقول تعالى: إِذَا السَّمَاءُ انْشَقَّتْ (1) وَأَذِنَتْ لِرَبِّهَا وَحُقَّتْ (2) وَإِذَا الأَرْضُ مُدَّتْ (3)وَأَلْقَتْ مَا فِيهَا وَتَخَلَّتْ . سورة الانشقاق
يقول تعالى: يَوْمَ نَطْوِي السَّمَاءَ كَطَيِّ السِّجِلِّ لِلْكُتُبِ [الأنبياء:104]،
يقول تعالى: يَوْمَ تُبَدَّلُ الْأَرْضُ غَيْرَ الْأَرْضِ وَالسَّمَاوَاتُ وَبَرَزُوا لِلَّهِ الْوَاحِد الْقَهَّارِ .( إبراهيم:48)
يقول تعالى: وَمَا أَمْرُ السَّاعَةِ إِلاَّ كَلَمْحِ الْبَصَرِ أَوْ هُوَ أَقْرَبُ (سورة النحل :77)
وهذه الايات تشير الي :
خلق الله تعالى العدد الهائل من المصابيح ( النجوم مثل الشمس) داخل الكره الداخلية الاولى فقط و هى السماء الدنيا ، ووقود هذه المصابيح هو تفاعلات نوويه ينشأ عنها إنطلاق كميات هائله من الطاقة ويتبع ذلك إزدياد الضغط داخل الكره و يتمدد جدار الكره و يتسع الكون ومع زيادة معدل اتساع الكون أى اتساع الكره و تمدد محيطها الخارجى (اذا الارض مددت ) و يزداد تسارع خروج المجرات من الثقوب السوداء( الفتحات فى جدار السماء) و مع تسارع خروج المجرات بما فيها من نجوم يظهر إختفاء ضوء النجوم ( اذا النجوم طمست ) و كل شئ عنده سبحانه بمقدار فيصل تحمل جدار الكره ( الارض جميعا و السماوات السبع) الى نهاية المدى فى الوقت المعلوم الذى حدده سبحانه و تعالى ومثل اى بالونه عند إزدياد الضغط داخلها كثيرا فى لمح البصر أو هو أقرب تنفجر الكره وتتشقق السماء ويتناثر ما بداخلها من كواكب وتطوى طبقات السماء السبعة على بعضها و يقع كل ذلك هناك على أرض غير الارض و تحت سماء غير السماء (يَوْمَ تُبَدَّلُ الْأَرْضُ غَيْرَ الْأَرْضِ وَالسَّمَاوَاتُ وَبَرَزُوا لِلَّهِ الْوَاحِد الْقَهَّارِ)
