How Scientists Reacted to Gravitational Wave Detection 

Shame that so many people in the comments do not understand this (well, at least a dozen so far). They think science is woo woo and that skepticism is a fault. Anything other than immediate results isn't science to them.

It's because companies like buzzfeed post stories the second a scientist says they might have something. Like when NASA says they found a new planet in the Goldilocks zone, buzzfeed goes out and says "NASA just discovered a new planet that they say may harbor sentient life" its the complete lack of attention span feeding the downfall of good science...

Exactly... we have model of an atom which was proposed by many scientist like rishi kannad, jj thomson, rutherford, neil bohr who disproved earlier discoveries.

eivilcow What about the linear thermal expansion at a measurable scale with a caliper or on a quantum level? If this device can detect a change in distance down to 1.0E-18 meters, then I'm sure it has to do with the thermal expansion and contraction of the mechanical components on this big rig. Think about it: I chose 410 stainless steel for the metal since it has a low thermal expansion coefficient [a], aluminum is over twice that. Linear Thermal Expansion - dL = L_o × a × dT Where...... dL = 1.0E-18 m L_o = 4,000 m a = 9.9E+6 m/(m-K) dT = ? So...... dT = 1.0E-18÷[4,000 m × 9.9E-6 m/(m-K)] dT = 2.5E-17 K That is only a temperature change of 0.000000000000000025 degrees Celsius needed to show this change between the two waves of these lasers! Not possible to control the ambient temperature in the lab to be that steady.

Peter Taylor That is why they built two of them. any errors that are caused by thermal strain or vibrations will only be seen in one and will be independent of the other. therefore they can calibrate them off each other and search for the patterns that are the same in both of them. Think of it as a DNA electrophoresis but with a couple hundred million bands instead of a few dozen. If you put in both sets and pull out only the parts that match up, then you get information that is independent of local error. Ideally there would be more than two because everyone knows that there are two spots on exact opposite sides of the planet that have the same temperature and pressure, so it is possible that the two machines will experience a hiccup that is close enough to get past the filters. I totally get where your argument is coming from, 10^-18 is absurdly small, but I am just saying that they seem to at least be trying to put in their due diligence and find and eliminate all of the errors that they can that could bias their results.

It took him 3 weeks to reach a "slow boil"! Insane! I too am sceptic as hell sometimes but it damn sure is refreshing.

hahahahahahahaha, mate. that's exactly what I was thinking. amazing. simply amazing.

Scientists are generally quite skeptical today!, 100 years ago we hardly even did peer review. Sure there are problems to improve on, but things are probably better than ever.

after all these toiling skepticism to assure truth, politicians comment:"scientific facts are just narratives" i.e. climate change

I just spent an afternoon reading about new-age-like "studies" and "discoveries", and this video is so refreshing. THIS is the border between "science" and the real science: skepticism. These guys worked so hard to prove themselves wrong.

yeah I found his story fascinating - not the reaction I expected.

Derek, Prof Adhikari seems real interesting. You guys talk about anything else for future videos?

2veritasium yes! I watched so many videos since the announcement, so many lectures. And his story is completely different and more real sounding.

Yup, I totally agree :) Not to say that the first video isn't awesome, it is, great job, but the neaty gritty is in this one, I feel.

Easily the least nerdy physics nerd I've ever seen. Brilliant interview.

Unless it's neither black nor a hole

@@Chopped_Liver oh 😳

🗿

Who is he? And which college did he come???

@@meetpremchandani3531 his name is Rana Adhikari

Which college brother?

Was the college IISc or IIT?

@@ishikinokami1575 Probably ICTS Bengaluru

TheGrandadParadox underrated comment

Truth.

Plus his orange crocks

Unwashed Unironed Unclean Underrated

He pulled it out of the hamper 5 minutes before leaving for work.

Absolutely the sign of a great interviewer.

@@demzynavarro3415 That also depends on the interviewee. If the interviewee abuses his opportunity, interviewer needs to cut him off. This is observed in politicians.

Saw this msg, liked it After four years That's how gravitational waves works

This youtube is a masterpiece and one of the few that I watch a couple of times a year

I mean he is not Neil DeGrasse Tyson

Especially after looking forward to it for 20 years

sadakotube he's an MIT PhD, shows his class

Digging around for weeks for literal tin foil conspiracies that could explain the result before believing what they wanted to believe. I'm kind of in awe.

People from India should learn from him. Atleast my religious parents should, haha!

@@bijeshshrestha2450 and he was born in India.

my guess is that if that powerful a laser had its light even reflected on a wall across the complex you would go instantly blind, might help a bit in case of a catastrophic failure.

Plus he's lookin' pretty fly.

Yeah like others said it's to protect from stray reflections. See styropyro's video in which he played with a tattoo laser. His camera wasn't even facing the laser but its sensor got a bit damaged due to reflections

it makes him look cool!

@@nilaksh007 There are probably also pump-lasers at play which have much less power and against which you can protect yourself with the glasses.

generally really smart people don't care about looks or clothes

@E Wrong.

@E that you're wrong

@E what you mean smart people in school dont make it big?

Lol

ummm so literally what all good scientists do all the time everywhere?

You're implying that they're all good. There's a lot of scientists who "massage" their results until they get something worth publishing. Even high end scientists do it, like people who synthesize new chemical elements.

Right! But here's the thing, he wasn't even happy about it. I don't get the point of this. He feels so bored about it, while its one of the greatest discoveries of the XXIst century! I'd have gone crazy at first, and then doubt it. But not always doubting that much; that, in my opinion, removes a bit of humanity. But I'm not him, and he can be whatever he wants to be. :)

Charles Hanson Descartes would be proud

That's what happens when scientists are pressured to publish to keep their position. It doesn't make for good science.

Most of the stuff today, is already discovered or invented or explored or ... For some, life is already too good to be true.

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XWzXq3sbAbk.html

And you stole this quote from I-can't-remember-who.

That's because these discoveries is the data matching years and YEARS of theoretical calculations. So either "That's funny." or "That seems to match the hypothesis." would be likely. The greek guy found a solution to a problem and therefore yelled: "I have it!" being Eureka in Greek.

@@kumardigvijaymishra5945 you understand that we have only mapped 35% of our oceans? There is still much unexplored territory below the waves

Ross Gabriel it should be, guy's shirt*. Possessive not plural.

In "this guys shirt" there should be an apostrophe so it should be "guy's," since the guy owns the shirt.

In this case no, because the shirt belongs to the guy. It's more like saying "that's Ross' hat"

Ross Gabriel the apostrophe is used as the possesive indicator rather that a plural as death by youtube said. guy's shirt does not mean guy is shirt

leave it to the English teachers to argue over grammar on youtube comments.

I thank you for this comment. Its like science comes with mathematics and a lot of boring stuff which we, impatient beings like to avoid. Look at this guy, he is after this for 20 years! Cannot believe his level of patience! Science needs more patience than anything else.

If you have talent and you have qualifications, you can ask these institutions for raw data and interpret them yourself. Who knows maybe your findings can help.

@@eveillanderson You mean his jackie onasis?

@@Ying-yang6969 It depends. There is a lot of statistics and background that needs to be learned first. Talent won't get you much unless you take the time to understand preexsisting science first.

Wow PhD on gravitational waves.. super cool

hey really great i am also willing to get a PhD after my Undergrad gets over and along the way I am making videos on science would you spare 5 mins of your time to comment how is my content ??

Sister. What kind of single did you mentioned and for what purpose? (Are you in iit?)

The universe predicted that these people would turn on the detector in 30 minutes shy of a billion years.

Now that you put it that way I also got goosebumps! just the right time!

He's one of my profs.... He's like this every day

Much to learn, you still have.

This guy is a tenacious dude... He doesn't get discouraged when things don't work out.

@@fgbhrl4907 Not in a hurry ; hype need not apply.

The guy is enlightened.

Working on a subject for more than 10 years takes its toll.

And he was blessed by a perfect event when they turned on their gizmo. Gods looking out for this dude. :)

They aren't shades , they're goggles to protect him from the equipment

@@thesci-fibro5835 was this response generated two years ago and only just arrive via gravitational waves? I have no recollection of writing this comment. Seriously. That's how long ago it was. Thanks ?!

@@ScarletIbis531 you're welcome ?!

@@ScarletIbis531 lemme remind you again

I agree. Such a brilliant, beautiful, human, deep, timeless, and powerful thing to say.

I really want to say the editor should get a raise, but I’d rather have the money split in a way where a reasonable amount, is used to get high quality information like the kind in this video. That said, I agree. The cello was an awesome touch that helped intensify the point of patient excitement.

That is his Einstein homage

Something wrong with that shirt?

@@sriharshacv7760 Nothing a little ironing wouldn't cure... and maybe get it a size larger?

@@carlwitt7950 story says he had it for 2 decades

I'm not even a scientist or someone doing particularly important stuff and I view dressing up as a waste of time. Buying clothes is a waste of time AND resources. I wear the same 5 shirts to work every week, in the order i take them out of the washing machine.

You were always a part. It hurt me really when today I realised the need of captions in any video. Thank you

@@anirbanmandal3123 😭😭😭

I wish you the best of luck for future.

@@krishnayashas8360 :D

🤗

briansmobile1 didn't expect to see you here. 😏

You spoiled it

You're missing that at the very beginning he didn't even bother to look at the measurement and only did because the others who he discouraged from bothering kept looking at it despite him. There's a fine line between skepticism and cynicism and when you start ignoring things that are actually valuable, that's cynicism.

@@EGarrett01 glass half empty, glass half full - eventually someone will want to sip from it. I agree, you might be right, but what's important is his perspective changed.

@@EGarrett01 its just his figure of speech i think. He didnt wanna hype it up cause it might introduce a bias. He decided to look at it kn a more condusive atmosphere

@@Saucemcfloss You can't change your perspective if you don't look at things that might change it.

really he is very clear

I need to get my shirt pressed!!

"Spends billions" "The first results are in!" "I don't care (yet)"

😂😂😂

Reminds of one of my science teacher in high school, coolest teacher I ever had

Why not move to Pasadena, enroll at Caltech, and obtain a BS in physics? Chances are, you'll run into him in the halls of the Physics Dept. building

idk maybe he is single go for it champ

He didn't look at it at all, that was cynicism. Others kept checking it despite him discouraging them from doing so. You need to doubt, but not to to the point that you assume negativity and don't bother.

He seems like gangster

I noticed that a lot of great scientists are also very drawn to art and especially music

That's right; Promote someone out of where they are effectual, because they are effectual, to a position where they can no longer impact the thing they're good at. /Peter Principle

There are lasers in the room, high power ones. Protection is necessary. And yes, the video is safe to watch.

Whatever is going on in this room, your computer screen can't do it, so don't worry x)

guys.. it was a joke lmao

xD ok, couldn't know.

I've read to many comment to rely on "well, that has to be sarcasm". Have a good day, bud!

He seems like gangster

Haha, so true. When I measured my Phd stuff we thought it looked like an artifact and repeated the measurement about 10 times in slightly different and more careful ways which took about a year before we finally succumbed to experimental evidence.

Comes with the job.

No it doesn't. It comes from extreme neglect.

Following Feynman "whatever man, I don't have time for this nonsense"

doesn't iron his clothes.

Aint nobody got time for that!

Black holes are described by just a few parameters. It's a single point with position, velocity, rotation and mass, period. Neutron stars are waaay more complex to model!

@@leogama3422 sure, buddy

@@Alienytical But that is indeed true.

@@leogama3422 What does the period represent...

@@leogama3422 Kinda hard to model a black hole when we don't actually know what happens at the center were all of our known physics breaks down.

you made my day by this comment. I tried it and couldn't stop a laughing riot :) LOL hahahahahahahahahaha

LOL

:o wow

It's so easy to be smart!

No, they're actually just cool scientists. Well... I guess both statements can be true then.

maybe just massively hungover

They look like laser protection glasses to me

I'm imagining their heads being vaporized, all except the glasses which hang in the air for a second before falling.

+Ƹ̵̡Ӝ̵̨Ʒ It's funnier than that. Their whole heads would be vapourised EXCEPT for a roughly glass-shaped slice of head, which would fall out of the pink gas cloud and slop onto the floor. It's very "Happy Tree Friends" : )

haha yea, just realized that. We may use that for our channel as well! Thanks!

I find the publication tool generally excellent and I wonder (RU-vid superstition here) if it gives RU-vid time to prepare itself because it knows exactly when something is going live... Maybe makes for a better launch experience?

2veritasium I'm sure it definitely does give RU-vid notice (via batch-processes on the back-end). Launch experience is definitely extremely important to RU-vid!

Two good videos at once. I like it.

thats a conspiracy

haha...

Is that a sarcastic laugh?

Dramawind nope

:v the roughness :v

I agree, I wish he would re-upload without the music

I disagree completely. It makes brings the analogy directly to the viewer and lets you know that the video is probably ending soon, providing a sense of closure and a smooth transition into the outro.

Yeah but he's saying how a recording doesn't give all that much detail (vs live performance) and we start hearing a recording of music, so it kind of goes against what he's trying to say. Felt a little out of place even though it was a nice transition

Music? I was so enthralled by the content that I didn't even notice music until you mentioned it here!

Alexey Kutepov Exactly what I was thinking... I just couldn't remember what the phenomenon was called. More research and a sound theory is necessary.

Ah, his name is Rana Adhikari! Really, sorry. It was shown so fast I barely noticed it. :)
