GW190521 was the name given to a gravitational wave event observed by LIGO and VIRGO in May 2019, and after a year of analysis and modelling it’s now clear that not only was this the largest gravitational wave event ever recorded, but, it required progenitor black holes which were more massive than can be created by a supernova.More information on LIGO & GW190521

Counting that amongst the “things i don’t want to be any closer to”
In bananas, how much energy was released?
Excellent editing/narrating. Thank you!
If someone can simulate this it will be interesting to see how such an event will affect the planet or how it will look like if happened at sun distance from the Earth.
So given the intensity of this event, how far from us would it have to have occurred to end life as we know it?
Someone downvoted this less than a minute in?
How very scientific of them. :/
I read an article about this yesterday and I could hardly comprehend it. Also, Einstein is my hero. Imagine the things he could’ve discovered with today’s technology.
saw your review on the netflix series about the asteroid coming to earth, you should check out the new one “away” it will make you cringe, so many issues with it that will make you laugh
Question: would these gravitational waves be emanating enough energy to tear a sun-sized star apart in the vicinity? (Like, how would this event have affected us if we were in the same galaxy as it?)
Does that mean something actually can escape from a black hole?
Holy crap! That’s phenomenal! Though I tend to lean towards the multiple mergers hypothesis, it would be insanely cool if we found out that these were primordial black holes.
So, I did the math, and that black hole merger released so much energy that it accounted for 1/250th of the energy output of the ENTIRE OBSERVABLE UNIVERSE!!! This merger released more energy in its last second than billions of galaxies do in the same amount of time!
Detecting gravity waves and the Higgs Bosun are the two greatest discoveries in the last decade.
could the energy dissipated by the merge be dark matter. Energy that exists in gravitation waves.
Those merger animations are mesmerising.
I paused @ 0:30….to collect myself….more energy in one second than our entire galaxy does in 1000 YEARS…welp, there ARE things worse than 2020. Thankful for that.
If gravity can lens gravitational waves, and said waves move “only” at the speed of light, how come the gravitational waves can make it out of the black hole’s event horizon at all?
Ok so everything went over my head.
Yet again lots of interesting information, one of my favourite YouTube subs
This video was really really exciting! Love those kind of videos you make explaining those events or other spacecraft missions.
great video. I have difficulty with the concept of “gravitational red-shifting.”
The universe definitely has its ways of humbling us puny apes, although converting 9 solar masses into energy in a single event is overkill.
Almost as energetic as Jacksepticeye’s intro
Hey Scott I had a question ..
What if an event close to this happened a few light years away from us ? What effects are we talking about
Wondering if the energy in gravitational waves is focused to a tiny point, could they create a blackhole by themselves.
Just like concentrating sunlight with a lense.
theoretical physics is so amusing )
There’s some clever buggers on the planet to figure all this out, that’s for sure.
Thats how to end a vid.
Scott,
Love your videos.
But I can’t let this one pass.
A single AGN is not an active galactic nuclei. “Nuclei” applies when there are two or more. Here you would use “nucleus.”
4:14 – 4.3miilon tons PER SECOND !
We are looking into the past.
This signal represents something phenomenally energetic, but realize that LIGO and friends had only been detecting signals for four years at this point. It’s possible that this was just a fortunate occurrence – maybe we just got lucky and happened to get our instruments running just before this one in a jillion event. However, it seems more likely that this sort of thing happens fairly regularly in the observable chunk of the universe, and that far more energetic events are yet to be observed.
I just love it when Scott’s video topics follow up on presentations on the same topic that I visited at my local astronomy club just the day before. Synchronicity rulez!
Boiling an ocean doesn’t seem so far-fetched now
We’re constantly hearing about how hard to detect gravitational waves are, and it makes sense. But, what would these mergers look like at closer distances? A hundred lightyears? Ten? One?
We need Telescopes and Gravity Wave detectors on the Moon and Ceres.
More of this Scott please!!! just amazing
10:17 That’s a lot of “Star Power” 🤩
Staggering!
More energy in one second than an entire galaxy outputs in a thousand years!
🤯
Thanks for the video, never stop uploading please!!!!!
This legit just convinced me to buy Universe Sandbox 2.
I mean, there were a bunch of factors, but this was the Franz Ferdinand.
Thank you for discussing this event. Fascinating!
I listen to a lot of audiobooks and I’m still waiting for Scott Manley to start narrating my favorite books. Hint hint.
Are gravitational waves the form of energy with the highest entropy?
Thank you for being on our ludicrous future…. it was nice to have someone who actually knows about space talking about it and putting Tim in his place!
Its amazing how we can detect an event that happened billions of years ago
Hulo, it’s Scott Manley here… Ride the Gravitational Wave safe!
no sorry that was just my taco bell…
“It releases more energy in a second than our galaxy does in a thousand years”, I believe your describing a toddler there.
I’m imagining someone in the future when we can finally travel to distance stars saying “where shall we go?” “Let’s look at that star” ” Sorry that’s not there now” “what about that one?” “Nope it’s gone too”
How would these powerful gravitational waves affect nearby stars? For example, what would be the affect on our Solar system if such an event happened 15 LY away?
That Sir Scott, is one of the best episodes yet!
Wait. Gravitational wave was redshifted… That’s only about the rotation frequency. Since we don’t know the wave function of gravity, and we don’t have a particle associated, the gravity itself isn’t redshifted. Or is it?
“e=mc^2= a lot of energy”
that’s a good sentence to end
This made my brain bigger
I literally have no idea what anything in this video means. For all I know hes just making it all up.
Maybe its just three helicopters at the same time?
Is there a ‘richter scale’ for gravity wave events?
“Unpossible?” An impossible word!
With all that energy released in gravity waves, what would the effect be on nearby stars and solar systems? I have a feeling nothing good.
It’s such a crazy and cool thing that mass got converted into gravitational waves
If you were near one of these events, would it be possible to “surf” on the gravitational waves?
Thanks Scott! Fantastic. As an engineer, I love the graphs and detail. More please.
Billions of years ago: WHABAM!
Earth: Forms
Evolves life
Life builds specific equipment to detect weird events
Specific equipment detects weird events
Smart man interprets weird events to keen learners
Keen learners: Dang thats a LOT of energy
An active galactic nucleUS. One nucleus, two nuclei. Gotta leave a nitpick with my thumbs up
Scott Manley:
Me: I’m learneding!
What would those kind of gravity waves do to the human body in close proximity?
That simulation at 6:40 was beautiful, cheers Scott
It’s just aliens. BOUT TIME 2020!
My first thought; That’s heavy, man, 🤜🤛
Rick ‘blackhole’ James: Gravity is a helluva drug
Good to see that since I was a physics undergrad gravity waves have gone from a purely theoretical abstraction to something we’re measuring almost routinely
it’s amazing being aware of this super duper space science, and then looking outside the window
well boys, ill see yall in December when we get the info on this.
“It was 5.7…”
Me: 5.7 Gly – yeah, that’s pretty far
“…Gpc”
Me: WHAT???
If I did the math right, that’s about 2.846*10^42 twinkies of energy released by that event
I wonder how far do you have to be from the event to actually feel tidal effects of such waves.
“Impossible” — Universe: Hold by beer!
It seems crazy to me that these waves could travel so far /without/ running into any gravity strong enough to noticeably lens it. I suppose that speaks to how relatively sparse the universe is?
“Now, as you know, the LIGO and VIRGO telescopes use…”
Yes, of course. I mean, who doesn’t know all this. * nervous side eye *
Pay no mind to this Yog-Soggoth and Nyarlathotep were just having a slapping contest.
… in an active galactic *nucleus*.
Phew, ok I saved the internet.
Amazing visual representations of what we believe is actually happening
powerful stuff going on out there
6:38 that simulation is so freaking cool
6:49 “And the star starts to burn prop… fuel” Too much rocket news lately, right? )
Was just waiting for someone to cover this 😉
Welp… we’ve found our alien overlords, and accidentally just scanned their jump drives.
You just can’t understand the scale of the energy, other than in abstract terms
Great presentation..
I love how Scott can just say “as you know” when talking about stuff since we’re all Space nerds.
If entire stars worth of energy are essentially turned invisible through conversion to gravitational waves, and given the age of the universe, how much energy is potentially ‘hidden’ as a result? Could gravitational waves be a major contributor to the theorized ‘dark energy’ that is unaccounted for?
I’m so glad I found this channel back when I got into KSP years and years ago
Wow, they don’t make black holes like they used to.
“This event happened billions of years ago before the earth was created, the energy is only now sweeping past the Earth” That level of scale disorienting
“gravity can lens gravitational waves”
my brain doesnt know how to handle this information
It kind of kills me how we’re now just talking about antimatter star supernovae like it’s just another blase matter of fact thing and when I was a kid we didn’t even know if black holes really actually existed at all yet. Hell, we didn’t even know if other stars had any planets!
6:51 when you almost said stars burn “propellant”, LOL
“If you’ve seen black holes do 6 impossible things this morning, why not round it off with breakfast at Milliways, the Restaurant at the End of the Universe?”
To maybe put the “9 solar masses into energy” into perspective: The Hiroshima bomb is calculated to have “only” converted 0.7 grams of matter into energy!
9 solar masses converted entirely into energy is too much to imagine.
It’s so much energy that comparing it to something a billion times less energetic is still too much to imagine
