We’ve been waiting to verify the existence of Gravitational Waves for over 100 years and I actually got to go to LIGO to see exactly how they proved it!
I know, this video is a bit different from most Physics Girl videos. It's part of a new PBS miniseries called Stellar, done in collaboration with Matt O’Dowd from @PBSSpacetime and Joe Hanson from @It'sOkayToBeSmart. Over six episodes we travel to telescopes, go inside space research centers, and chat with amazing scientists. Next up is Joe's episode where he visits one of the telescopes that was part of world-spanning Event Horizon Telescope.
Check out the other episodes in this series:
The Quasar from The Beginning of Time | STELLAR
• The Quasar from The Be...
Seeing a Black Hole with a Planet-Sized Telescope | STELLAR
• How To See a Black Hol...
You'll be able to see future episodes on the Physics Girl, Space Time and It’s Okay to be Smart KZfaq channels, as well as the PBS Digital Studios Facebook page.
Stellar is a part of the PBS Summer of Space. They'll be lots of awesome space related content all summer long on PBS. See what's happening at www.pbs.org/summer-of-space/
#SummerOfSpacePBS #astrophysics #space
Special Thanks to Michael Landry, Amber Strunk, and the whole LIGO Hanford team for all their help making this episode.

Hey, I'm Dianna and you're watching Physics Girl. I know, that part of the video is missing. So is HAPPY PHYSICSING! SORRY! Let me explain. This video is part of a PBS Miniseries called Stellar done in collaboration with PBS Spacetime and It's Okay to Be Smart. There will be videos on their channels too, and one more on Physics Girl in 3 weeks. For the context of this video, let's go back to when I was a wee undergrad studying physics. Back then, there were experiments that physicists agreed were potentially going to be HUGE for modern physics - discovering the Higgs boson (we did that recently!), taking the first image of a black hole (we just did that too!). But a really big experiment was aiming to measure gravitational waves, and I remember being told we didn’t know if we’d measure them any time soon, if ever. But in 2015 we measured the first gravitational wave. It was a HUGE moment! Not just for physics, but for all of science! And the observatory that made the discovery was LIGO. For this video, which is part of a PBS space series that i’ll explain more in the description, I GOT TO GO TO LIGO. The best part was sitting with the head of the observatory and asking him all my questions about the universe in the downtime of the shoot. One of the coolest days of my life. Anyways.. I hope you enjoy this series!

Hi Dianna! I love your work! Can you or someone in this comment section explain to me two things please? First, since LIGO operates virtually identically to the Laser Interferometry used in the Michelson-Morley experiment, how does LIGO overcome the problems they had in the MM experiment, namely the Lorentz-Fitzgerald contraction issues from the motion of the Earth? Secondly, If the Moon has enough gravitational influence to lift millions of tons of ocean water, the why does LIGO NOT detect this massive gravitational influence, but instead is able to detect an event that happened a long time ago in a galaxy far-far away? Also, if this gravitational effect was so strong when it was detected 3 years ago, how come we never felt those effects in any other way? After all, we do see and feel the gravitational effects of the Moon and this event was supposed to be orders of magnitude stronger. Thanks in advance for your answer! :-) - Melissa
@jochen4207 5 жыл бұрын
I can help you in (3) She describes the gravitational waves as "huge" but it's huge in comparison to other gravitational waves. She also said "spacetime moved by the distance equivalent to a billionth of a proton" which is clearly not huge in the macro scale. That's why you didn't feel it at all
@victorcodesseira 5 жыл бұрын
I might be wrong here, but about the moon, I think the probable answer is the frequency of the wave. Yes, the effect the moon has is of very high amplitude, but its period spans a whole day, so it's easier to differentiate from other sources. Besides that, this is one of the reasons they have 2 different observatories, in different places. The effect of the moon(and even earthquakes and other sources of error) moves "slowly" through the planet, and so any vibrations caused by these sources would be of different amplitudes and phases in the 2 observatories. Gravitational waves, on the other hand, move at the speed of light, and interact weakly with matter, so you would get a really similar wave within a maximum time delay of 0.01 seconds(depending on the direction the wave is approaching from). So basically, you have the 2 interferometers working together to filter out any local disturbances, on top of the suspension system.
@JustSomeCanuck 5 жыл бұрын
First point: I can't explain exactly how the designers would overcome that, but I am sure they have a way. Second point: I'm sure LIGO could detect the influence of the Moon, but that would be one of many unwanted signals that would be filtered out. The events that LIGO and VIRGO (the European one) have detected would have been massive if you were nearby. However, the first event detected occurred 1.3 billion light-years away. The waves are very weak after traveling that distance. Also remember that theoretical predictions of what a gravitational wave signal would look like are available, so part of the analysis is looking for signals that resemble the predictions.
@TheLocust830 5 жыл бұрын
The moon isn't actually lifting the water in the oceans. The tides are actually an effect of the drag the moon exerts on earth, also slowing earth's rotation in the process. It is quite similar to the way wind makes waves, just constant and worldwide.
@Blox117 5 жыл бұрын
if it was easier to detect gravitational waves from the moon it would have been done much sooner. but as victor says, the orbital inward merger of two black holes produces the highest frequency gravity waves. and only black holes are strong enough to produce those higher frequency waves.
