+Guus Tielens Think about you standing on a big trampoline in the middle... and then someone less than half your size (like a child) jumps on the trampoline and starts running around you... You would feel it when they jumped on and started running around right?!?! The trampoline is space time and you and the kid are both matter...You are a star and the kid is a large gas giant planet... you have more mass than the kid... you can feel it when he runs around you.. but he can also feel it and lose balance should you start jumping up and down erratically or even jump off the trampoline... Get it? ;)
+RatedMf0rmanly Well yeah; what we feel as weight is the attractive force between us and the centre of the earth. That attractive force is what we call gravity. Weight is a force. Weight is what we perceive as gravity.

yes look it up! curvature of space is flat. There is no relative here. It is flat from here and it is flat from other dimensions and it is flat from the edge of observable universe.
It's theoretically flat.. like the surface of a pond. ...until of course a cataclysmic event distorts that surface... Sooooo.. your flat theory is out.
As a chemistry postgraduate and also an evangelical Christian theologian who has studied science extensively and critically, I must, based on the overwhelming evidence, that the possibility of evolution by blind, chance, and random and impersonal accidents is scientifically and mathematically impossible. Conversely, the evidence supporting and intelligent and therefore conscious agent is overwhelmingly undeniable and in fact, irrefutable. Soli Deo Gloria! To God alone belongs all glory.
+mikemoair You think it's bullshit, because we got lucky? That's probably the dumbest thing I've read in this comment section; and I've read shit about flat-earth and religion here. So given with your statement, people who get lucky and win the lottery is bullshit, because it was a coincidence they were at the store just in time to pick up the winning ticket? You probably believe the Earth is 6,000 years old too, don't you?
This is what's great about real science...that things that are determined that SHOULD be there theoretically end up being proven to be there. It's so sad that things like this weren't proven within the theorists' lifetimes, since those are the things they were ultimately searching for. Personally, I'd always thought it was pretty safe to assume Einstein was right about this, but I'm sure many other were too, but just waiting for the ability to prove it.
+xnonsuchx Einstein was remarkable, and this demonstrates it yet again. But just as Einstein showed Newton's theory was incomplete, quantum theory has shown that relativity is incomplete, as it doesn't work on the atomic scale. He worked for decades to come up with a Theory of Everything, but to no avail. This could have been a part that was wrong, leading us to complete it. It does wrap the large scale/fast movement things nicely in a bow though. Too bad he didn't live to see it.
+NorthernGamer The scientists who discovered it are skeptical too; that's there job. It's why they made more than one of the detectors and didn't announce it until they got a signal that was clearly detected by both detectors. It's also why they're building more detectors so next time there will be several detectors that get it the correct fraction of a second apart. That's the way science works. If you're not skeptical, you're in the wrong business. But you do what you can to overcome the objections to your theory or experimental methods. Successful theories (relativity, evolution, atomic theory, germ theory) stand up to scrutiny by making predictions that are confirmed by multiple independent experiments and/or observations. Until today, relativity had passed every test save one, the detection of gravity waves. The rest of it is so solid, we rely on it to make GPS work. It's golden.
pahtar Well, the word "theory" wouldn't nessecarily be associated with evolution these days, even though the word "theory" could also be used as a set of ideas to explain something. The model I use to visualize the basic phenomena and behaviour of the universe does not consist of theories, rather factual individual ideas (ie the earth is round, evolution happened in the past and is still happening, stars being in clusters and galaxies, etc).
I read about the extensive equipment needed to measure gravity from extraterrestrial sources ("LIGO") a long time ago, and I'm glad to see that it has returned some pertinent data.
MirrorBeing besides Ligo actually just claimed to use two in this case so you are deluded there as well - just type ligo fake blind injections or gravitational waves are fake or relativity debunked or I AM NO EINSTEIN! - cz we living in an electric universe son...
"Matter tells space how to curve, space tells matter how to move." This is one of the greatest scientific discoveries of all time, but THAT QUOTE IS JUST AS BRILLIANT!!
Mr. Tyson -- You are very smart. You know a lot about a lot of things. I saw you in the video, "The Universe -- Beyond the Big Bang". I was impressed by your demeanor and by the way you explained things. You do not need to use cuss words in order to get your point across, or in order to emphasize anything. Everything you say is already impressive! Leave out the cuss words. : ) I loved all of this information. It helped me to better understand the LIGO contraption and the way it works.
5:42 he is talking about discovery from 1998 but he don't realizes it actually proved that universe isn't expanding. Watch my movies for more info. Discovery from 1998 showed that Hubble law is wrong. It's about redshift from distant galaxies, It is no longer linear, proportionate do distance from Earth. Hubble shouldn't assume it was doppler effect.
Neil very elegantly said that Einstein nor him know the true meaning of the word force in physics. In physics, a force is any interaction that, when unopposed, will change the motion of an object. In other words, a force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. First a Physicist is needed that CAN define gravity. Then find a wave to match.
Einsteins theory of relativity equations show that space bends, and proves that nothing is really something with substance. Space is shaped, and it is the shape that creates the gravity and creates and controls everything in the universe. Nothing causes everything to happen. Nothing creates gravity, gravity creates planets and stars thus everything physical comes from and is created by nothing. For the first time in mankind's history we can Know the truth of life, we can know the fundamental big picture and it can and will transform mankind and the world when enough people see it. This is truth you can and should check for yourself, this is truth the evidence suggests. Google *_Truth Contest_* and read the top entry called "the Present".
+Jerry Salo Went to the site. Sounds like a creepy ass, pseudo-intellectual/spiritual, cult. The dude that wrote it is absolutely insane - he is so sure that he has all the answers. Sorry, but the atheist/skeptic in me doesn't trust weird bullshit like that.
Europe has CERN, the US has LIGO. Europe made a huge discovery in the subatomic level, Higgs Boson. The US made a huge discovery in the cosmological level, Gravitational waves. Has anyone noticed that? I actually think it's a good idea that each nation works on the other end of the spectrum, until we manage to combine them and get the theory of everything.
And both are absolute folderol. Fermionics is a nice idea, but completely unobservable. The Higgs Boson is a mathematical answer looking for a question, there is nothing in the observable universe to suggest vector-gauge or mass is controlled by Fermionic properties or if there even are set Fermionic properties at all. LIGO is based on "A laser did something weird, it must mean the universe is shaking" using the device as the answer to the specific hypothesis and discounting all available other reasons why a phenomena occurred with no further research or experimentation.
Ok my question is, how did scientists even detect the colliding black holes that led to the discovery of gravitational waves? As far as i know, black holes are not visible. So how did they detect them
+Karlita 1 You're right, they haven't detected them. They don't know where exactly the event took place, but have a rough estimate based on how the waves reached both detection sites. Black holes existence can only be inferred anyway, by looking at the massive tug on the objects around them or identifying the gamma ray burst from them "digesting" matter around them. However, the gravitational waves weren't just a simple blimp. The had a very complex structure which fitted perfectly with what was predicted in a mathematical model. Based on that model they calculated the sizes of the black holes, energy released and stuff like that.
+Karlita 1 The black holes themselves cannot be directly observed, you're absolutely right. We can observe them *indirectly* however by observing an effect known as gravitational lensing, as well as watching them consume stars and other bright matter. The gravitational wave that we detected is not something that you would see with your eyes, or even with a telescope. It's a ripple in the fabric of spacetime, and the two devices we created were able to detect that ripple. In a way the devices work in a similar way to telescopes, but they don't see visible light, they see ripples in the fabric of spacetime. And by looking at the waves that were detected, we were able to not only determine where that wave came from, but also what created it. That's part of why people are so exited about this new discovery. I hope that helps answer your question!
+Karlita 1 The other commenters explained everything already nicely. I just wanted to add that black holes are not so black. You are right that they cannot emit light from within the event horizon since any light that has crossed the event horizon is trapped. But they do emit x-rays due to quantum effects right at the event horizon. It is called "Hawking radiation".
+compuholic82 whats astonishing to me is that they claim to know what the event was, when it took place and the fact that this was set up at just the right time period in 1.3 billion years to catch the wave passing earth.. really?
Matthiu Ryin These types of events are happening all the time all over the universe. This was just the *first* detection, there have been many since and we will continue to see them. Their models predicted that we should get some kind of detection within a couple weeks of the detector being sensitive enough to detect them. And we did. And think of it like a sound wave. When we hear a sound it's pretty obvious what direction it came from, and with analysis we're able to get a pretty good idea of what made the sound. Gravitational waves are fairly similar. Except in this case we already knew what would be making the waves we detected, because the only thing LIGO is sensitive enough to detect is gravitational waves made by black holes. That and the signal we got matches perfectly with our models for such an event. Hope that helps.
+Will Moffett You're bombarded with gravitational waves every single day. You have been your whole life. The one that was big enough for us to detect when we happened to be looking did not change anything. Sorry, your life is getting better for other reasons.
+Dan Downing You can't be sure of that. The universe is treating me differently- I can feel it. I know it sounds crazy but some people I know also have reported changes of outlook and fortune, though I have not broached this subject with them. I can't explain it, but I am a rational person. I trust in that rationality and have to go with what my senses and pattern recognition tell me. If I had to call it one thing, I would simply call it luck. Maybe it won't last, and its not absolute, but the coin is landing on the side I need it to more often, noticeably so and at the right time. I have been thinking that something happened Thursday, and I just found out about this disturbance in space/time yesterday. Never before have I attached any unexplained significance to a random day. And to then find out space/time has been altered... I suppose now some others might be out of sink now. I can't help that. They've had their time and I hope they've enjoyed it.
That ''badass smart'' (and yes, he was indeed) was also a theist (no, not Atheist but Theist). How's that for a ripple in your time-space scientific community?
Lol...nobody gives a shit loser? Oh fuck a scientist from the past believed nonsense that he could never of proved with science and never tried? What are we gonna do? PACK IT UP ATHEIST THIS GUY PROVED GOD WITH HIS "POINTS"
Honest question here: if the collision of black holes were to happen way closer to us, let's say I don't know: 50 light years away, would the gravitational waves have an stronger effect and a stronger measurement would be achieved?, like it is mentioned that the disturbance was so incredibly small that detecting this was a monumental achievement on engineering in itself. Any ideas?
+Devon Henry Wtf is a flat earther? I mean, I can surmise it's people who believe the earth is flat but, surely these people doesn't actually exist any more, do they?
+GamerHats You will be surprised how many smart thinkers actually get trapped in that ancient pitfall - it comes from the lack of trust in government - but flat heads take it too far - they throw all logic out the window and favor it for conspiracy - I am not surprised that after so many mellenia not one flat head found the edge yet....
How they know it's more energy than all the stars in the universe combined? 2:20 What equipment or methodology was used to count them all? Stars are as infinite as space itself! Anyway, Neil deGrasse is one of my favorite scientist.
“I don’t know if there is anything left that Einstein predicted that we can still end up finding is true. Everything has been correct” (Neil deGrasse Tyson, 4:30). Maybe there is something else. Einstein was not a Christian, but he read the Gospels and believed the pure teachings of Jesus are “capable of curing all the social ills of humanity.” Read the New Testament gospels and find out why Einstein was "enthralled by the luminous figure of the Nazarene."
Ken Ham, in my opinion, confuses the Gospel (see 1 Corinthians 15:1-5) with a young earth. In his debate with Bill Nye, Ken was asked, _“ Hypothetically, if evidence existed that caused you to have to admit that the Earth was older than 10,000 years, and creation did not occur over six days, would you still believe in God, and the historical Jesus of Nazareth, and that Jesus was the son of God?"_ Ken’s answer should have been a clear and resounding, “Yes.” It wasn’t. Ken Ham's "gospel" of a young earth is not the Christian gospel. www.c-span.org/video/?317578-1/evolution-versus-creationism-debate
again theories are a guess. the bible is historical fact. every archeologist that had tried to disprove it has only proved it and converted their way of thinking. Even darwin on his death bed said that he was christian, and regretted his theroy.
+Aaron Goerner (Bible-Quran) ...Total and complete nonsense. In a letter to Beatrice Frohlich, 17 December 1952 Einstein stated, "The idea of a personal God is quite alien to me and seems even naive."[11] Eric Gutkind sent a copy of his book "Choose Life: The Biblical Call To Revolt to Einstein in 1954. Einstein sent Gutkind a letter in response and wrote, "The word God is for me nothing more than the expression and product of human weaknesses, the Bible a collection of honourable, but still primitive legends. No interpretation no matter how subtle can (for me) change this. These subtilised interpretations are highly manifold according to their nature and have almost nothing to do with the original text.
Wow, this is big news... I can't believe it finally happened in my life time... I studied how we been watching a few double black hole systems since 2011 & waiting but not knowing when it will happen... This is going to open our eyes to even more of the cosmos to better understand it... I haven't been this stoked since I watched comets hit planet Jupiter...
Can someone explain or provide an easy to understand link on the distortion of space, resulting in gravity? I don't get how it works. Space isn't a flat disc, so wouldn't a massive object be distorting space in all different directions? I can't visualize in my mind how this works.
+project 2501 I suspect it has something to do with using multiple detectors spread across the world. Any seismic activity is probably detected by all of them, but depending on how close the epicenter is the precise measurement also changes. They were looking for something that comes from very far away, and thus it registers exactly the same way at all locations.
+project 2501 with seismic detectors. Any distortions they got that happened during an earthquake anywhere near the experiment had to be disconsidered because there was no way to prove they didn't come from the quake; they found things that could be gravitational waves thousands of times during the tests but every time they ended up throwing the results out because they weren't infallible (earthquakes, cars passing by, loud noises, anything really); the five months they spent checking the results of this gravitational wave were just to check every possibility and make sure that it wasn't another false alarm ^^
+project 2501 They used a 2 fold system. 1.Active Isolation: dampens vibration using actuators which physically vibrate 180 degrees out of phase to the incoming seismic wave. 2.Passive Isolation: a 4 stage pendulum system from which the mirror hangs and isolates any outer interference.
1916 paper Newton - gravity - force of attraction between two objects Einstein - gravity is distortion of space and timeb Matter tells space how to curve Everything has been correct
+chicken It was really important to know, because we just learned that gravity is basically a form of waves. We didnt know anything about gravity before, so this is huge actually. If we learn more about it (and we will) then we can use gravity for our advantage in science and to understand how the universe works. There were also the important questions whether gravitational waves move faster than light or at the speed of light or maybe a little slower. If its faster, one could potentially use it in the future to go faster in space (although it is more sci-fi at this stage), while if its at the speed of light then we would know it has no mass, but if its a little bit slower then we would know that gravity has mass, which would complicate the theory even more as everyone thought gravity would have to be something without mass. Its not impossible, but improbable. This might not be a big thing for us at the moment, but rest assured this is going to be in the history books in the future as the moment where science has gotten to a new, huge leap! The moment where we started to learn and potentially understand how to actually use gravity! :) This message was from Gabor George that I accidentally erased. Show less
Why it is important: For the first time, humanity has a way to observe the sky that is not brought to us by photons. (The photons in the detectors were local, not from the observed event itself.) _It is like gaining a new sense,_ kind of like sight, kind of like hearing, but able to observe a completely different set of phenomena. Think of all the things we see that would never occur to a blind person, or things we hear that a deaf person would not know about. This is like that, _except no creature in the history of the planet has ever had this sense._ We will seek to observe other massive mergers, clues to dark matter, epochs earlier than the last scattering of photons, etc., but there is so, so much room for things nobody ever thought of.
There's one gigantic flaw in Einstein's theory of gravity, and that's that he doesn't prove or even attempt to explain why an object would follow a curved path. Imagine the example that most people give when explaining Einstein's gravity, the one which they suggest is like a bowling ball on a mattress. So in the middle of say a very large mattress, there is this rather huge bowling ball that's sinking down the mattress in the spot that it occupies. You then take a tiny marble and push it towards the center of said mattress and sure enough, it rolls down into the crevasse created by the bowling ball. Why did it do that? Well, yes, half of the reason is because the bowling ball has distorted the mattress' "spacetime", but the other reason is because gravity is pulling it downwards. Without the gravitational *force* (as opposed to curved spacetime alone), the pushed marble would simply continue on its horizontal trajectory and coast right over the sunken part of the mattress. My point is that even if a mass is distorting spacetime, an object only sinks toward it because that force of gravity it pulling it towards it (again, not simply because space is curved). It's the same concept as if you got into a vehicle and drove towards the Grand Canyon. The reason that you'd fall down into the canyon is not solely because there is a gigantic hole, gravity still has to pull you down *into* that hole as well. Otherwise, you'd drive right over it. Einstein was wrong. Or at the very least, his theory is quite incomplete.
I don't understand one thing though, how probable is it that the blackhole merging ripple reaches the Earth in this miniscule timeframe that the detector has been turned on? Or is it a very common activity in the universe, one occurring every year or so? Or is it a continuous thing lasting hundred or thousands of years, and not just a flash of vibration?
Gravitational waves confirm the fact that there is no absolute measure of time or distance in the universe so there is no absolute measurement of the age or size of the universe.
Would love to see this guy on the Stuttering John show..Im sure John is intelligent enough to have a deep conversation about matter, time/space and such
This is so relaxing it makes you forget about financial mind set that money is everything it dont even matter.Science technology will free people one day.
Newton's gravity near 300 years old also predicts gravity waves. Newton said "gravity is a force", as a force it must have a force carrier we call the graviton, all force carriers travel in waves.
how did they know if the mirror was not merely moved by idk a gust of wind or something and not a gravitational wave emitted by two black holes coalescing?
so when my fat ass makes the couch sag, i'm actually distorting space-time

I cant even process how smart Einstein was, makes you wonder how much of a difference he could of made with the tools we have now.
Next to none, nothing he postulated was demonstrably shown to be true, other people simple did what he couldn't then attributed it to him.

MirrorBeing besides Ligo actually just claimed to use two in this case so you are deluded there as well - just type ligo fake blind injections or gravitational waves are fake or relativity debunked or I AM NO EINSTEIN! - cz we living in an electric universe son...
"Matter tells space how to curve, space tells matter how to move." This is one of the greatest scientific discoveries of all time, but THAT QUOTE IS JUST AS BRILLIANT!!
If the Bible was this good at predicting things I'd be a believer.
Mr. Tyson -- You are very smart. You know a lot about a lot of things. I saw you in the video, "The Universe -- Beyond the Big Bang". I was impressed by your demeanor and by the way you explained things. You do not need to use cuss words in order to get your point across, or in order to emphasize anything. Everything you say is already impressive! Leave out the cuss words. : ) I loved all of this information. It helped me to better understand the LIGO contraption and the way it works.
This is why we love Neil. FUCK YEAAA SCIENCE!!!!!!!!!!!!!!!!!!!!!!!!
5:42 he is talking about discovery from 1998 but he don't realizes it actually proved that universe isn't expanding. Watch my movies for more info. Discovery from 1998 showed that Hubble law is wrong. It's about redshift from distant galaxies, It is no longer linear, proportionate do distance from Earth. Hubble shouldn't assume it was doppler effect.
I love how extremely excited Niel DeGrasse Tyson gets talking about the universe. No possible way of interrupting him during a rant.
Wow, Anthony seems substantially more well informed than I thought. I only really knew him from Louis C.K. on Opie and Anthony
+Tech Deth If he agrees with Tool Tyson, he's not well informed. ;-)
"forget Aristotle, and fuck Socrates.. here comes professor Anthony"
Einstein was vehemently against the uncertainty principle, which was considered fact by the time he died.
Imagine this interview but it's Opie and Neil
Great guest and great timing on getting him. I could listen to Neil for days.
Neil very elegantly said that Einstein nor him know the true meaning of the word force in physics. In physics, a force is any interaction that, when unopposed, will change the motion of an object. In other words, a force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate. First a Physicist is needed that CAN define gravity. Then find a wave to match.

"We are pretty excited because we have measured a part in 1000...we are looking for a part in 10000" - Dr. Gabriela Gonzalez 2012 Awesome Work!
Einsteins theory of relativity equations show that space bends, and proves that nothing is really something with substance. Space is shaped, and it is the shape that creates the gravity and creates and controls everything in the universe. Nothing causes everything to happen. Nothing creates gravity, gravity creates planets and stars thus everything physical comes from and is created by nothing. For the first time in mankind's history we can Know the truth of life, we can know the fundamental big picture and it can and will transform mankind and the world when enough people see it. This is truth you can and should check for yourself, this is truth the evidence suggests. Google *_Truth Contest_* and read the top entry called "the Present".
+Jerry Salo Went to the site. Sounds like a creepy ass, pseudo-intellectual/spiritual, cult. The dude that wrote it is absolutely insane - he is so sure that he has all the answers. Sorry, but the atheist/skeptic in me doesn't trust weird bullshit like that.
+Chris Meade The funniest thing is that Einsteins theory of relativity doesn't work with spiritualism.... Spiritualism is a quantum thing....

Chris Meade Haha.. keep telling yourself that man. .. \m/
Brian Griffin Ugh such a typical, condescending, douche response. No critical thinking, just lol your dumb for not believing my fairy tales. Grow up
Europe has CERN, the US has LIGO. Europe made a huge discovery in the subatomic level, Higgs Boson. The US made a huge discovery in the cosmological level, Gravitational waves. Has anyone noticed that? I actually think it's a good idea that each nation works on the other end of the spectrum, until we manage to combine them and get the theory of everything.
And both are absolute folderol. Fermionics is a nice idea, but completely unobservable. The Higgs Boson is a mathematical answer looking for a question, there is nothing in the observable universe to suggest vector-gauge or mass is controlled by Fermionic properties or if there even are set Fermionic properties at all. LIGO is based on "A laser did something weird, it must mean the universe is shaking" using the device as the answer to the specific hypothesis and discounting all available other reasons why a phenomena occurred with no further research or experimentation.
Ok my question is, how did scientists even detect the colliding black holes that led to the discovery of gravitational waves? As far as i know, black holes are not visible. So how did they detect them
+Karlita 1 You're right, they haven't detected them. They don't know where exactly the event took place, but have a rough estimate based on how the waves reached both detection sites. Black holes existence can only be inferred anyway, by looking at the massive tug on the objects around them or identifying the gamma ray burst from them "digesting" matter around them.
However, the gravitational waves weren't just a simple blimp. The had a very complex structure which fitted perfectly with what was predicted in a mathematical model. Based on that model they calculated the sizes of the black holes, energy released and stuff like that.
+Karlita 1 The black holes themselves cannot be directly observed, you're absolutely right. We can observe them *indirectly* however by observing an effect known as gravitational lensing, as well as watching them consume stars and other bright matter. The gravitational wave that we detected is not something that you would see with your eyes, or even with a telescope. It's a ripple in the fabric of spacetime, and the two devices we created were able to detect that ripple. In a way the devices work in a similar way to telescopes, but they don't see visible light, they see ripples in the fabric of spacetime. And by looking at the waves that were detected, we were able to not only determine where that wave came from, but also what created it. That's part of why people are so exited about this new discovery.
I hope that helps answer your question!
+Karlita 1 The other commenters explained everything already nicely. I just wanted to add that black holes are not so black. You are right that they cannot emit light from within the event horizon since any light that has crossed the event horizon is trapped. But they do emit x-rays due to quantum effects right at the event horizon. It is called "Hawking radiation".
+compuholic82 whats astonishing to me is that they claim to know what the event was, when it took place and the fact that this was set up at just the right time period in 1.3 billion years to catch the wave passing earth.. really?
Matthiu Ryin These types of events are happening all the time all over the universe. This was just the *first* detection, there have been many since and we will continue to see them. Their models predicted that we should get some kind of detection within a couple weeks of the detector being sensitive enough to detect them. And we did. And think of it like a sound wave. When we hear a sound it's pretty obvious what direction it came from, and with analysis we're able to get a pretty good idea of what made the sound. Gravitational waves are fairly similar. Except in this case we already knew what would be making the waves we detected, because the only thing LIGO is sensitive enough to detect is gravitational waves made by black holes. That and the signal we got matches perfectly with our models for such an event. Hope that helps.
Unbelievable! science at its best moving humanity forward
My life has been getting better and better since that ripple. Anyone else?
+Will Moffett You're bombarded with gravitational waves every single day. You have been your whole life. The one that was big enough for us to detect when we happened to be looking did not change anything. Sorry, your life is getting better for other reasons.
+Dan Downing Now you've probably made him upset :(
Don't worry will, my life has also been getting better since then.
+Dan Downing Now you've probably made him upset :(
Don't worry will, my life has also been getting better since then.
+Dan Downing You can't be sure of that. The universe is treating me differently- I can feel it. I know it sounds crazy but some people I know also have reported changes of outlook and fortune, though I have not broached this subject with them. I can't explain it, but I am a rational person. I trust in that rationality and have to go with what my senses and pattern recognition tell me. If I had to call it one thing, I would simply call it luck. Maybe it won't last, and its not absolute, but the coin is landing on the side I need it to more often, noticeably so and at the right time. I have been thinking that something happened Thursday, and I just found out about this disturbance in space/time yesterday. Never before have I attached any unexplained significance to a random day. And to then find out space/time has been altered...
I suppose now some others might be out of sink now. I can't help that. They've had their time and I hope they've enjoyed it.

Lol...nobody gives a shit loser? Oh fuck a scientist from the past believed nonsense that he could never of proved with science and never tried?
What are we gonna do? PACK IT UP ATHEIST THIS GUY PROVED GOD WITH HIS "POINTS"
Honest question here: if the collision of black holes were to happen way closer to us, let's say I don't know: 50 light years away, would the gravitational waves have an stronger effect and a stronger measurement would be achieved?, like it is mentioned that the disturbance was so incredibly small that detecting this was a monumental achievement on engineering in itself. Any ideas?

How they know it's more energy than all the stars in the universe combined? 2:20 What equipment or methodology was used to count them all? Stars are as infinite as space itself! Anyway, Neil deGrasse is one of my favorite scientist.
Tyson is about as credible as Geraldo
Yes but what causes that gravitational destrortion? anyone can explain?
“I don’t know if there is anything left that Einstein predicted that we can still end up finding is true. Everything has been
correct” (Neil deGrasse Tyson, 4:30). Maybe there is something else. Einstein was not a Christian, but he read the Gospels and believed the pure teachings of Jesus are “capable of curing all the social ills of humanity.” Read the New Testament gospels and find out why Einstein was "enthralled by the luminous figure of the Nazarene."
I would like to see neil debate ken ham.
Ken Ham, in my opinion, confuses the Gospel (see 1 Corinthians 15:1-5) with a young earth. In his debate with Bill Nye, Ken was asked, _“ Hypothetically, if evidence existed that caused you to have to admit that the Earth was older than 10,000 years, and creation did not occur over six days, would you still believe in God, and the historical Jesus of Nazareth, and that Jesus was the son of God?"_
Ken’s answer should have been a clear and resounding, “Yes.” It wasn’t.
Ken Ham's "gospel" of a young earth is not the Christian gospel.

+Aaron Goerner (Bible-Quran) ...Total and complete nonsense. In a letter to Beatrice Frohlich, 17 December 1952 Einstein stated, "The idea of a personal God is quite alien to me and seems even naive."[11] Eric Gutkind sent a copy of his book "Choose Life: The Biblical Call To Revolt
to Einstein in 1954. Einstein sent Gutkind a letter in response and wrote, "The word God is for me nothing more than the expression and product of human weaknesses, the Bible a collection of honourable, but still primitive legends. No interpretation no matter how subtle can (for
me) change this. These subtilised interpretations are highly manifold
according to their nature and have almost nothing to do with the original text.

When engineers and scientists get together they transform the world.
Can someone explain or provide an easy to understand link on the distortion of space, resulting in gravity? I don't get how it works. Space isn't a flat disc, so wouldn't a massive object be distorting space in all different directions? I can't visualize in my mind how this works.
I remberedwhen this happened.
.this is such amaxing discovery
I searched "ninth green at 9pm" and this was second to the happy Gilmore clip. I was not dissapointed.
Does anyone know how they prevented seismic activity from messing the experiment?
+project 2501 4:03 He doesn't specify, but they've thought of it ^^
+project 2501
I suspect it has something to do with using multiple detectors spread across the world. Any seismic activity is probably detected by all of them, but depending on how close the epicenter is the precise measurement also changes. They were looking for something that comes from very far away, and thus it registers exactly the same way at all locations.
+project 2501 with seismic detectors. Any distortions they got that happened during an earthquake anywhere near the experiment had to be disconsidered because there was no way to prove they didn't come from the quake; they found things that could be gravitational waves thousands of times during the tests but every time they ended up throwing the results out because they weren't infallible (earthquakes, cars passing by, loud noises, anything really); the five months they spent checking the results of this gravitational wave were just to check every possibility and make sure that it wasn't another false alarm ^^
+project 2501 They used a 2 fold system.
1.Active Isolation: dampens vibration using actuators which physically vibrate 180 degrees out of phase to the incoming seismic wave.
2.Passive Isolation: a 4 stage pendulum system from which the mirror hangs and isolates any outer interference.

Newton - gravity - force of attraction between two objects
Einstein - gravity is distortion of space and timeb
Matter tells space how to curve
Everything has been correct
+chicken It was really important to know, because we just learned that gravity is basically a form of waves. We didnt know anything about gravity before, so this is huge actually. If we learn more about it (and we will) then we can use gravity for our advantage in science and to understand how the universe works.
There were also the important questions whether gravitational waves move faster than light or at the speed of light or maybe a little slower. If its faster, one could potentially use it in the future to go faster in space (although it is more sci-fi at this stage), while if its at the speed of light then we would know it has no mass, but if its a little bit slower then we would know that gravity has mass, which would complicate the theory even more as everyone thought gravity would have to be something without mass. Its not impossible, but improbable.
This might not be a big thing for us at the moment, but rest assured this is going to be in the history books in the future as the moment where science has gotten to a new, huge leap! The moment where we started to learn and potentially understand how to actually use gravity! :)
This message was from Gabor George that I accidentally erased.

+Nooblenin Because your brain recognizes b. s. when it hears it. ;-)
thats a well informed host, finally a host who relishes the science rather then belittling it trying to be funny
Why it is important:
For the first time, humanity has a way to observe the sky that is not brought to us by photons. (The photons in the detectors were local, not from the observed event itself.)
_It is like gaining a new sense,_ kind of like sight, kind of like hearing, but able to observe a completely different set of phenomena. Think of all the things we see that would never occur to a blind person, or things we hear that a deaf person would not know about. This is like that, _except no creature in the history of the planet has ever had this sense._
We will seek to observe other massive mergers, clues to dark matter, epochs earlier than the last scattering of photons, etc., but there is so, so much room for things nobody ever thought of.
A fan of both of these gentlemen.
There's one gigantic flaw in Einstein's theory of gravity, and that's that he doesn't prove or even attempt to explain why an object would follow a curved path. Imagine the example that most people give when explaining Einstein's gravity, the one which they suggest is like a bowling ball on a mattress. So in the middle of say a very large mattress, there is this rather huge bowling ball that's sinking down the mattress in the spot that it occupies. You then take a tiny marble and push it towards the center of said mattress and sure enough, it rolls down into the crevasse created by the bowling ball. Why did it do that? Well, yes, half of the reason is because the bowling ball has distorted the mattress' "spacetime", but the other reason is because gravity is pulling it downwards. Without the gravitational *force* (as opposed to curved spacetime alone), the pushed marble would simply continue on its horizontal trajectory and coast right over the sunken part of the mattress. My point is that even if a mass is distorting spacetime, an object only sinks toward it because that force of gravity it pulling it towards it (again, not simply because space is curved). It's the same concept as if you got into a vehicle and drove towards the Grand Canyon. The reason that you'd fall down into the canyon is not solely because there is a gigantic hole, gravity still has to pull you down *into* that hole as well. Otherwise, you'd drive right over it. Einstein was wrong. Or at the very least, his theory is quite incomplete.
Yes... yes, yes, yes. Yes!
I don't understand one thing though, how probable is it that the blackhole merging ripple reaches the Earth in this miniscule timeframe that the detector has been turned on? Or is it a very common activity in the universe, one occurring every year or so? Or is it a continuous thing lasting hundred or thousands of years, and not just a flash of vibration?
Like in interstellar ?
can this device be used in earthquake prone areas to detect upcoming eathquakes? this might save lots of lives...
He said the power of the two black holes merging was more than all the stars in the universe, but it's ACTUALLY 50 TIMES MORE!
"That's badass smart"
I'm dying.
Am I mistaken, or did Neil Degrasse Tyson at the very end say of Albert Einstein, "we got a badass over here."
Gravitational waves confirm the fact that there is no absolute measure of time or distance in the universe so there is no absolute measurement of the age or size of the universe.
I hope to love anyone one day as Neil degrass Tyson loves himself.
Great explanation as always.
Would love to see this guy on the Stuttering John show..Im sure John is intelligent enough to have a deep conversation about matter, time/space and such
1:18 "Spacetime tells matter how to move; matter tells spacetime how to curve." John Archibald Wheeler (en.wikiquote.org/wiki/John_Archibald_Wheeler)
This makes more sense than Newton
How did or can LIGO Identify the source of the ripples?
Did this discovery shaken up the quantum theory? I'm no expert but from what I've learn the two theories do not really mix? Is that right?
This is so relaxing it makes you forget about financial mind set that money is everything it dont even matter.Science technology will free people one day.
Newton's gravity near 300 years old also predicts gravity waves. Newton said "gravity is a force", as a force it must have a force carrier we call the graviton, all force carriers travel in waves.
Hi Mr. Tony, can you speak to your video guys about the focus problem? The city is sharp but you and Mr. DeGrasse are a bit soft. P.S. You rock Sir!
I have to think hard to make a sandwich and then it slips off my plate. I wish I was smart.
how did they know if the mirror was not merely moved by idk a gust of wind or something and not a gravitational wave emitted by two black holes coalescing?
How do we know exactly what caused the wave? How do we know it was caused by two black holes coalescing?
one correction, "at OR AROUND the speed of light". the speed is not fixed because of other variables. carry on.
Neil gives me life.
