I thought gravitational waves were old news, but I guess you guys like this video! Next week will be the extended interview with Ligo Hanford Observatory head, Michael Landry. It's gonna be quite an experiment to see how you guys like a VERY long interview video...
What i like in your videos is the dynamism that you give them. I hope that there will be at least a little of it in this long interview. Also hope that it will be a well constructed and interesting interview. Knowing the quality of your former videos, i think you will manage to do it. Hello from France =)
Detecting gravitational waves have been fundamental to cosmology. After the collision of two neutron stars was detected, a new excitement in neutron stars captured the Earths imagination. Neutron stars are so strange ie magnetors and pulsars and more. You are amazing for all young scientists but especially women. (I’ve been really into superconductors and magnets lately.)
I went there while the LIGO was being constructed. I remember being blown away by the explanation of how they had to correct for waves hitting the shore hundreds of miles away because they were close to the right frequency and the amplitude was close to what they were expecting from the event. I was so excited when all that work resulted in the outcome they were hoping for, and for the variances which are now spurring new scientific activity.
@@kilmorepowerchairs2142 They don't know, that's the point. To say that such and such wave produces a variation of 1/10,000 the width of a proton is a gravitational wave is absolutely ridiculous, the whole thing is just a big scam...
I will build a gigantic sort of globe, made of stone, mud, layers of molten iron, nickel, and minerals, really huge, like 40,000 kilometers round the belly. Then I am going to launch it into the universe in order to find out if there is a force called gravitas (lets name it so) that will catch my ball and lock it in a magneto electrical forcefield. It may take some time, but it really feels exciting already. I' ll keep you posted on my progress..
My step grandpa helped build the tunnels. He was part of the team that figured out all the engineering for the curverature, how to keep the concrete from cracking, and some other cool stuff for the construction/design of the tunnels themselves.
When Washington became a state it was supported by Lumber west of the mountains. But the US was smart and wanted each new state to be financially stable for centuries so they made them expand there borders to include other industries that would grow if one of them failed. So they included the mountains and eastern Washington. These areas had mining and agriculture. Which supported our state until Boeing and Microsoft. Areas of eastern Washington have plenty of rain shadow areas away from the big rivers. deserts.
I am not used to thinking of it as a real 'desert' -- I reserve that honor to places like the Mojave Desert -- but I did know that Eastern Washington was much drier and hotter than Western Washington thanks to the mountains that block all the moisture coming from the Pacific.
Exactly BillyFYT. I hear that. It all sounds so interesting but I have the slightest? If only they could describe it in a way they would try to explain it to a 4 year old or something? I want to be able to understand it all so bad but I just get lost, and fast.
Yup. It adds to her charm and charisma. Btw, you've waited a year to get this like to put you in triple digits. Way to hang in there and not disappear, oh great magician.
The fact that the machine can even *DETECT* these gravitation waves that stretch things on a *QUANTUM SCALE* is absolutely insane. How have humans come this far?
My favorite thing is that one of the lead scientists was out when the detection was made, and when he came back and people told him he was just like "Whatever, we just turned it on. Can't be real, just go back to work." And it took him like a month to start taking it seriously.
I love trying to figure out the economics behind creating a system this big. Concrete tunnels, super sensitive lasers, huge liquid nitrogen tank. Tons of resources to manage!

In a previous profession I was an engineering surveyor, meaning that I used survey instruments to collect data for civil engineering designs. Yes, I actually used a theodolite, engineer's level, and 100-ft steel tape. Level shots were restricted to 300 feet or less because of curvature and refraction. Shots longer than 300 feet need to be corrected. It pleased me to hear the statement about having to correct for curvature in the tunnels. I had to smile. Thanks for sharing this episode.
@@drachebueb4211 Springs absorb the energy. The idea is having springs heavy and long enough to absorb all of the energy without transferring that energy past the springs into the structure the opposite end of the spring is attached too.

I found out who or what the kardashians are, the one posted a selfie today showing off a hot body, still a fake person living in an illusion and fantasy world, far from reality as possible, nice looking, not sure how much she paid for it, i guess her dad or her mom has purchased one for them selves too, please dont make that video, i would much rather watch one about the bolts flying around , or any of the other many things no one ever speaks of, like the iridium flashes, the flying bolts, etc. Etc.
7:24 It's two nonillion, or 2,000 octillion tsar bombas. And remember that while the tsar bomba was detonated in the north of Siberia, it blew out the windows in Norway
9:15 if that's the readings they're detecting, then I'm very curious how much does a car accelerating nearby or the crows pecking at the ice etc affecting the readings?
I'm just wondering how they can even hope to tell its working, there is just so many things that could interfere with both test that are way closer. Most earthquakes can on a slace larger then that be felt all the way around the earth though greatly diminished. It just dosent seem practical when teir is so much in our own solar system???
Most people think of C as the speed of light. In reality it is the maximum speed of the universe. So anything that moves at maximum velocity movies at the same speed as light because both of them are moving at C which is the maximum speed of the universe. Radio waves also travel at maximum speed. So if gravity has a speed it makes sense it is C.
It's always handy to remember that when we talk about the "speed of light" we're not actually talking about light* so much as the maximum possible speed that any signal/information can be sent. In that sense, everything has a speed, and gravity just happens to be in the special class of phenomena that operates at max speed (or so close to it as to be indistinguishable). *Of course, it does also describe the speed of actual light in a vacuum.
Yeah I thought that the effects of gravity were instant, wasn't that the premise of of Interstellar or something? Using gravitational waves in order to communicate instantly?
@@skeptic1000 I don't think there was any faster-than-light communication in Interstellar, unless you count communicating through a wormhole. But that's not really "faster than light," it's just taking a different route.
I'm amazed how this girl presents her videos she is so much fun! She puts smile on my face every time I watch a new video from her. she makes boring science fun. I've learned so much more from her than from teachers!!!🤣 Definitely recommending this channel. Physic teacher, learn from this brilliant mind!!!!
Something wrong about the speed of gravitational waves. The calculations done forecasting GW at the speed of light shows planets spiraling into the sun in a relatively short period of time.
@2:13 those springs that isolate the equipment shown. i have been installing and fabricating those systems for over 30 years. the springs are actually called "isolators" and are almost always installed with those systems. they generate alot of vibration and you usually don't want that type of constant stress on a building. it also helps transmit sound, and people don't like that either. so while the isolators under that equipment in your video do indeed function as you claim, they are not unique to your application. they are in fact, commonly used.
I have been following the LIGO discoveries and I am fascinated to say the least. This video helped answer many of my questions. I am looking foreword to your next one. Thanks! Well done!!
Magnetism can whoop gravity any day,...so you just put a big magnet in that book and find a steel shelf. That anti gravity won't ever show its face around you again.
Isn't that like asking does sound have a resonant frequency? You need an object for the sound to resonate in and it's the properties of the object that determine the resonant frequency. I would be interested to know the answer though
@@oliverwilson11 that's kinda why I asked lol I'm just going off of if gravity is measured as a wave or emits waves would it not have a measurable frequency?
They do, and LIGO cannot detect waves of the wrong frequency. The issue is that 'gravitational waves' are different from 'gravity' in the same way sound waves are different from air pressure. We don't measure the strength of gravity as having a frequency any more than we'd measure the 'sound' of air pressure. Gravitational waves are small variations in the gravitational field, the ones measured by LIGO starting at about 35Hz and increasing to a peak of 250Hz (The signal 'chirps' as the merger progresses.)
@Ryan Stasiuk Given that we have so many names for different frequencies of electromagnetic radiation (infra-red, light, colors, radio, microwaves, x-rays, etc.), it’s surprising to eventually learn that they’re all fundamentally the same kind of wave-like energy. And it’s fair to ask if gravity is along that spectrum, and if not, if gravity behaves like a wave, too. The plain and simple answer is that gravity is a separate and unique form of energy (one of the four ‘fundamental interactions’) that is described as an attractive force between two masses. The force depends on the size of the masses and the distance between them, and does not have a fundamental or resonant frequency. What’s been discovered and what experiments like this are measuring, is that when very large objects in the cosmos abruptly change their mass (like when huge stars explode or collapse, or when black holes collide), the previously relatively steady force they exerted on us ‘vibrates’ or ‘rings’ for a few seconds or minutes as the object(s) catastrophically change. Those ‘vibrations’ have a low frequency that can be measured, but gravity itself is not a periodically varying phenomenon.
If gravitational waves are maxed out at speed of light (as far as we know) due to being tied to space/time, it would seem plausible that there's direct correlation with the expansion of space/time causing informations speed within that medium to slow down. Why that is.... Then again, are we slowing down or are the edges of the known universe speeding up?
We visited LIGO about 11 months before the video was made and recall the tubes had to be built in straight line, not following the Earth curvature, but also recall them saying the original tube diameter proved too small, so they had to use slightly larger tubes. With my hearing problems I didn't catch exactly why, and didn't get another chance to ask before we had to leave. It would be interesting to know exactly why they had to got to the bigger tubes, and if the display tube that had the thinness pointed out was one of the smaller diameter first set. I think I remember them saying that it was the smaller diameter version.
Space isn't a vacuum. It's well known that it's filled with plasma. Also, it's not good to present things as fact when they are theories or assumptions (e.g. That the cause was collision of black holes. The existence of black holes is also still just a theory) 😊
Many “theories” are not being published as fact because the hidden conspiracies behind them would also be stated as a result of the disclosure & it’s not time for it to be revealed. Mind bending isn’t it. Also, you’re getting a bit ahead of yourself as the “black hole” was recently established as fact. See what I did there. lol. You’re welcome. 😁
Right! We love being Suspicious Observers, learning of the Electric and Plasma Universe , and we especially love FIELD THEORY which Theoria Apophasis EXPLAINS (and not just describes) the phenomenon of magnetism, dielectricity, gravity, all that jazz. :)
The authoritarians of mainstream science and the Vatican, believe that just because we can't see it, then it doesn't exist and yet, they know it does, hence the term "dark matter". 75% of science and medicine and 89% of astrophysics is a construct designed to subvert the true nature about such things ..especially the true connection between Human consciousness and the creation of things within our perceived realities.
PS. People who waste time on fretting over conspiracy theories could apply themselves better by actively doing their own research. I believe that most of the accused (especially in science) are just doing the best they can like all the rest of us 😊
Gravity Waves, I knew it! Keep up the great work physics Girl. The tunnels gave it away. The long tunnels are needed to shine the lasers through. I understand some student researchers from my Alma Mater RIT were involved with the project. I didn't know holding a vacuum was involved. That's gotta be a major headache. I worked with high vacuum systems in a EM/SEM lab at the NIH... It was always something. You and Wonderful Person Anton Petrov i know are motivating our future and current scientists.
@@skunk12 Not when you know they're not actually crazy - they're just fascinated by what they're seeing and yearning for more knowledge. Unlike Ocasio-Cortez.
So... this means there is...Subspace? If Space is a fabric with a tensile strength, capable of movement, it is a medium within something else. Mind blown.
I'm reading these comments and I have a hard time with all the negativity and outright stupidity I find here. C'mon people this is very cool stuff. Physics Girl, you're great.
I only recently discovered your channel. I only watch it occasionally, because I need time for the information to sink in properly. I love the enthusiasm and excitement you show, because that's how I feel when I hear of new amazing strides in physics, astronomy, and other sciences (like developments in new materials, "solid smoke" as a slightly older example).

I actually had the pleasure of visiting the LIGO site in Livingston, Louisiana for my senior year physics class field trip. I would love to go there again if I could since I enjoyed seeing that kind of stuff.

I found out who or what the kardashians are, the one posted a selfie today showing off a hot body, still a fake person living in an illusion and fantasy world, far from reality as possible, nice looking, not sure how much she paid for it, i guess her dad or her mom has purchased one for them selves too, please dont make that video, i would much rather watch one about the bolts flying around , or any of the other many things no one ever speaks of, like the iridium flashes, the flying bolts, etc. Etc.
@@travisleeds2910 ...take a deep breath Sheldon...

There are billions of people in the world.... just becasue 3,000 of them watch a video about physics does not equalize the stupidity of the others....

You looked like a kid in a Candy Store. Oh and your contagious personality and enthusiasm pulled me in. Great job 👍
She has pretty teeth.
agree
@@adampastor She's just flat-out pretty.
Michael Palmer you collect teeth as well? We should compare our collection and swap duplicates.
In the first two minutes, you explained Gravitation Waves in a way that made me understand them like I hadn't before. Fantastico.
so I happened upon this by accident and although this is WAY over my head, your enthusiasm hooked me so much, I had to subscribe!
Same here I've always been interested in this stuff but it's over my head!
@@johnnyhawkins43 I try really hard to follow along! It's really interesting!
I just want to have 1/100 000 the passion that Dianna has for Physics (and I actually am a Physics teacher!!!)
I laughed at your comment Luis!
My high school physics teacher didn’t care about physics at all and it showed
@@TheBraddles82 That's very sad, Be Rad. Every kid should have a teacher (of any subject) that is excited about his/her class.
7:24 It's two nonillion, or 2,000 octillion tsar bombas. And remember that while the tsar bomba was detonated in the north of Siberia, it blew out the windows in Norway
2 followed by 30 zeros is 2 Octillion, isn't it?
The real shame here is some people would have a problem just with the fact that LIGO had to take into account the curvature of the Earth.
“Hey. Just observed some gravitational waves...”
“Nope. Just ravens pecking at the liquid nitrogen tanks again.”
“...”
lol gotem
9:15 if that's the readings they're detecting, then I'm very curious how much does a car accelerating nearby or the crows pecking at the ice etc affecting the readings?
I'm just wondering how they can even hope to tell its working, there is just so many things that could interfere with both test that are way closer. Most earthquakes can on a slace larger then that be felt all the way around the earth though greatly diminished. It just dosent seem practical when teir is so much in our own solar system???
Speed of gravity that's new
Most people think of C as the speed of light. In reality it is the maximum speed of the universe. So anything that moves at maximum velocity movies at the same speed as light because both of them are moving at C which is the maximum speed of the universe. Radio waves also travel at maximum speed. So if gravity has a speed it makes sense it is C.
It's always handy to remember that when we talk about the "speed of light" we're not actually talking about light* so much as the maximum possible speed that any signal/information can be sent. In that sense, everything has a speed, and gravity just happens to be in the special class of phenomena that operates at max speed (or so close to it as to be indistinguishable).
*Of course, it does also describe the speed of actual light in a vacuum.
It's all the same thing and it's the speed of causality.
PBS spacetime has a great video on exactly that.
Yeah I thought that the effects of gravity were instant, wasn't that the premise of of Interstellar or something? Using gravitational waves in order to communicate instantly?
@@skeptic1000 I don't think there was any faster-than-light communication in Interstellar, unless you count communicating through a wormhole. But that's not really "faster than light," it's just taking a different route.
You're energy is amazing explaining physics! What an awesome channel to stumble upon :)
I'm amazed how this girl presents her videos she is so much fun! She puts smile on my face every time I watch a new video from her. she makes boring science fun. I've learned so much more from her than from teachers!!!🤣 Definitely recommending this channel. Physic teacher, learn from this brilliant mind!!!!
Something wrong about the speed of gravitational waves. The calculations done forecasting GW at the speed of light shows planets spiraling into the sun in a relatively short period of time.
Sounds like a fun time TBH
@2:13 those springs that isolate the equipment shown. i have been installing and fabricating those systems for over 30 years. the springs are actually called "isolators" and are almost always installed with those systems. they generate alot of vibration and you usually don't want that type of constant stress on a building. it also helps transmit sound, and people don't like that either. so while the isolators under that equipment in your video do indeed function as you claim, they are not unique to your application. they are in fact, commonly used.
Di you work in the US submarine business? :-)
You have become my favorite UA-camr. It's a constant rotation but your knowledge and charisma is legit. Have you made a video on antimatter?
Yes it’s in her list of popular videos as the most expensive material, or something like that
I have been following the LIGO discoveries and I am fascinated to say the least. This video helped answer many of my questions. I am looking foreword to your next one. Thanks! Well done!!
I've been reading a book about anti-gravity. I can't put it down. haha.
John Chessant what a cheap one
Just plop it up on the underside of a shelf...
Magnetism can whoop gravity any day,...so you just put a big magnet in that book and find a steel shelf. That anti gravity won't ever show its face around you again.
I think that's funny...
that ol' chessant …. it's a keeper !
"The numbers we're dealing with here are..." Astronomical. I believe that's the word you're looking for. =)
Air conditioning "chillers" are always mounted on springs, it helps the gear to relieve mechanical stress on itself too.
So does gravity have a resonat frequency or even have a frequency at all??
Isn't that like asking does sound have a resonant frequency? You need an object for the sound to resonate in and it's the properties of the object that determine the resonant frequency. I would be interested to know the answer though
@@oliverwilson11 that's kinda why I asked lol I'm just going off of if gravity is measured as a wave or emits waves would it not have a measurable frequency?
They do, and LIGO cannot detect waves of the wrong frequency.
The issue is that 'gravitational waves' are different from 'gravity' in the same way sound waves are different from air pressure. We don't measure the strength of gravity as having a frequency any more than we'd measure the 'sound' of air pressure.
Gravitational waves are small variations in the gravitational field, the ones measured by LIGO starting at about 35Hz and increasing to a peak of 250Hz (The signal 'chirps' as the merger progresses.)
@Ryan Stasiuk Given that we have so many names for different frequencies of electromagnetic radiation (infra-red, light, colors, radio, microwaves, x-rays, etc.), it’s surprising to eventually learn that they’re all fundamentally the same kind of wave-like energy. And it’s fair to ask if gravity is along that spectrum, and if not, if gravity behaves like a wave, too.
The plain and simple answer is that gravity is a separate and unique form of energy (one of the four ‘fundamental interactions’) that is described as an attractive force between two masses. The force depends on the size of the masses and the distance between them, and does not have a fundamental or resonant frequency.
What’s been discovered and what experiments like this are measuring, is that when very large objects in the cosmos abruptly change their mass (like when huge stars explode or collapse, or when black holes collide), the previously relatively steady force they exerted on us ‘vibrates’ or ‘rings’ for a few seconds or minutes as the object(s) catastrophically change. Those ‘vibrations’ have a low frequency that can be measured, but gravity itself is not a periodically varying phenomenon.
Thank you and @Netpilot for actually taking the time and explaining it and not being like how the rest of the internet can be! Much appreciated!
Him: length matters. Her: remembers she thought that once
I love your content and your charisma!
You're a great person and always I watch your videos I get really happy!
You are awesome!
That is something that blew my mind! Space is "stiff" like solid substances, but it's a vacuum! WHAT!? Too cool and weird at the same time.
I love that you give this the excitement that is appropriate, it's really insane... :')
Another use for the Michelson-Morley experiment.
I needed a educational video right now. Thank goodness for Physics Girl!
You are soo amazing!! I pray you are healing well & quickly!! ❤
[09:08] It is worth considering that the speed of light has been proven NOT to have been a constant throughout time. It is actually slowing down.
can you blame it? i mean, it's been moving really fast for a long time! it's probably tired
If gravitational waves are maxed out at speed of light (as far as we know) due to being tied to space/time, it would seem plausible that there's direct correlation with the expansion of space/time causing informations speed within that medium to slow down. Why that is....
Then again, are we slowing down or are the edges of the known universe speeding up?
They are building a LIGO observatory in my city HINGOLI MAHARASHTRA STATE.
they found powerful gravitational wave their.
That was just all that dang rain 😕
Cool! With more of them around the world (and in space!) we can better triangulate the locations of these events.
Or.... This is what prior to the fake moon landings and star wars n star trek indoctrination....... Pseudo science or science FICTION 😂😂😂😂
1:18 to 1:35 Great example of field theory, and why gravity isn't an instantaneous "action at a distance" force.
Theoria Apophasis-ized? (if not, YT the name along with keywords Magnetism, Dielectricity, Gravity, Field Theory, Charles Proteus Steinmetz)
@@just1john Steimetz was certainly a remarkably gifted engineer.
We visited LIGO about 11 months before the video was made and recall the tubes had to be built in straight line, not following the Earth curvature, but also recall them saying the original tube diameter proved too small, so they had to use slightly larger tubes. With my hearing problems I didn't catch exactly why, and didn't get another chance to ask before we had to leave. It would be interesting to know exactly why they had to got to the bigger tubes, and if the display tube that had the thinness pointed out was one of the smaller diameter first set.
I think I remember them saying that it was the smaller diameter version.
Wow, now I've gotta binge watch. You make physics so easy.
Space isn't a vacuum. It's well known that it's filled with plasma.
Also, it's not good to present things as fact when they are theories or assumptions (e.g. That the cause was collision of black holes. The existence of black holes is also still just a theory) 😊
Many “theories” are not being published as fact because the hidden conspiracies behind them would also be stated as a result of the disclosure & it’s not time for it to be revealed. Mind bending isn’t it.
Also, you’re getting a bit ahead of yourself as the “black hole” was recently established as fact.
See what I did there.
lol.
You’re welcome.
😁
Right! We love being Suspicious Observers, learning of the Electric and Plasma Universe , and we especially love FIELD THEORY which Theoria Apophasis EXPLAINS (and not just describes) the phenomenon of magnetism, dielectricity, gravity, all that jazz. :)
The authoritarians of mainstream science and the Vatican, believe that just because we can't see it, then it doesn't exist and yet, they know it does, hence the term "dark matter". 75% of science and medicine and 89% of astrophysics is a construct designed to subvert the true nature about such things ..especially the true connection between Human consciousness and the creation of things within our perceived realities.
@@BobbyOfEarth the Vat gang ain't the only gang doing this to us all
PS. People who waste time on fretting over conspiracy theories could apply themselves better by actively doing their own research. I believe that most of the accused (especially in science) are just doing the best they can like all the rest of us 😊
The idea of precision to 10^-15 made me melt
What if he gets so small, he disappears into a pore of the bowl?
Gravity Waves, I knew it! Keep up the great work physics Girl. The tunnels gave it away. The long tunnels are needed to shine the lasers through. I understand some student researchers from my Alma Mater RIT were involved with the project. I didn't know holding a vacuum was involved. That's gotta be a major headache. I worked with high vacuum systems in a EM/SEM lab at the NIH... It was always something. You and Wonderful Person Anton Petrov i know are motivating our future and current scientists.

I had fun using an interferometer to check fiber optic connectors. Those interferometers look like lots of fun!
So... this means there is...Subspace? If Space is a fabric with a tensile strength, capable of movement, it is a medium within something else. Mind blown.
Great video, thanks! I live very close to LIGO Livingston and I'm planning to take the tour in Sept. Can't wait.

I only recently discovered your channel. I only watch it occasionally, because I need time for the information to sink in properly. I love the enthusiasm and excitement you show, because that's how I feel when I hear of new amazing strides in physics, astronomy, and other sciences (like developments in new materials, "solid smoke" as a slightly older example).
"How do we launch vacuum tubes to space?"

You build a GRID.
With no oxygen he raises a great point people chose too ignore
I still wonder, space is no perfect vacuum either. Shoudln't there be a device to keep all the small stuff and radiation out?
How do they manage to filter out noise at atomic level vibrations?
Vacuum & They know what they put in i.e. light from the laser. So they are able to account for it.

I actually had the pleasure of visiting the LIGO site in Livingston, Louisiana for my senior year physics class field trip. I would love to go there again if I could since I enjoyed seeing that kind of stuff.
The Ligo T-Shirt you're wearing - why is the 'L' not the 2 arms of the detector? Such a missed opportunity!

Great presentation Dianna. LIGO is blowing my mind. I had no idea space was so "thick".

How do they get the laser to follow the curvature of the earth? Because lasers travel in a straight line.
@Matt Logsdon Even the best mirrors do not reflect 100% of all radiation; some of the energy will still heat and eventually burn through the mirror.
They don’t. That’s why she said they have to compensate for the curvature of the Earth - the tube is higher out of the ground at both ends, more buried in the middle.
Dianna Cowern why is this moment so impressive: "Some people can't stop moving"? Just right into the heart!
