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.)

[@michaelterrazas1325]

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]

So how do they know that the event isn’t coming from some backwater beach in Thailand.

[@StillCloser]

@@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..

Just curious, how many of you didn't know there was desert in Washington?

[@ecospider5]

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.

Speed of gravity that's new

[@ecospider5]

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.

[@oppie2363]

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.

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.

[@aramboodakian9554]

I feel privileged to have worked on LIGO as an engineering Technician based in Pasadena at Cal Tech building and testing electronics for both interferometers in Hanford, WA and Livingston, LA. The modules I worked on were to compensate for the “ noise “ that is trying to interfere with reception. Such things as tidal motion hundreds of miles away from the observatories.

[@kevinbendall9119]

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.

[@riffrocker7401]

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?

[@TerryAVanguard]

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???

[@GeeveGeorge]

Hey Diana, Really great video! :) Just wanted to know, how did they find out the source/ point of origin (location of that point) of the gravitational waves? And how did they conclude that it took 1.3 billion years to reach earth. Would love to know the science behind that.

[@oppie2363]

I think the source would be pretty "easily" deducible by triangulation, since they're working with two incredibly precise receptors that are half a continent away from each other. ("Easy" to develop the method once you already have achieved all of the very difficult tasks to get that level of precision, I mean.)

[@dennismiller4969]

[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.

[@cheezyridr]

can you blame it? i mean, it's been moving really fast for a long time! it's probably tired

[@Armageist]

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?
