The European Space Agency Mission LISA (Laser Interferometer Space Antennae) will launch in 2034 and will revolutionize the way we do astronomy. With a 2.5 million kilometre arm length it will be able to see kinds of gravitational waves that are impossible to see using Earth based detectors. Cool things it will see are collisions of super-massive black holes, orbiting white dwarf stars and measurements that will calibrate distance measures like sephid variable stars and supernovae, and it will be a new independent way of measuring the Hubble constant.

We are so looking forward to expand our knowledge of the universe with LISA! 😃
Great video Dominic! Thank you very much for putting it together! 🙏
gotta be honest...never thought i'd see a comment on YT made by ESA
Such peaceful comment.....
Black wholes are made up of dark energy....
@@somanathdash8143 Yeah... no.
For students from UPSC exam: the answer is 'Evolved Lisa'.
Lisa pathfinder: a 2015 mission to study feasibility for evolved lisa, 2034.
LIGO: Underground
Evolved Lisa: In space
Lisa pathfinder: study feasibility for Evolved Lisa.
Its "EVOLVED" probably because antecedents like space time curvature, ligo, lisa-pathfinder etc
Your donut of knowledge is still my laptop background 🤩🤩

"2034 is a long time in the future"
You say that as if 2005 is a long time in the past.
Whoa! 🤯
I know, right?
Though, I realized I got the parallel wrong. 2034 is 15 years from now, and I meant to go 15 years into the past, but I accidentally went 14 years into the past to 2005.
2004 would've been 15 years ago and not 2005. Oops.
delve . Problem is 2004 I was alive and in 2034 I have a good chance of being dead. Even if I’m alive will I have the cognitive ability to appreciate what is discovered. Never mind I’ll just waste the next 5 or 10 years of my life working.
+Mit Seraffej
Why do you think you'll be dead by 2034?
delve .Because I’ll be 74. About the life expectancy in my country. I was not quite 9 when Apollo 11 landed on the moon. It was so exciting. I think it was in the early morning where I lived and I think we listened to it live on the radio. In my country TV was only introduced 4 years earlier. Once again mankind lost its way after that.
I first saw you from Vertasium on the Doom map video and I've since been hooked. You are so amazing at communicating science. I have never had in interest in quantum mechanics until your videos, and now I can't stop watching your videos. You are so smart and so good at explaining how things function in a way better than most science communicators. Thanks for being you :)
The best channel & a wonderful human being I've stumbled upon on UA-cam Thank you ❤🙏
Love the thumbnail!
Thanks so much! Full credit to the NASA Goddard Space Flight Center who made the full simulation of colliding black holes. There is a link to their video in my description.
Domain of Science I’ll definitely check the link out. Its a such a cool simulation.
Again A great video Sir!!
Outstanding effort
Thanks for such a cool explanation here. Love you all LISA
I think it will be much more revolutionary than the HST... After all, HST is just a telescope but in space. But LISA? Lisa is a completely different beast! It is not a different league. It's a completely different sport!
Thanks for the video it is very informative☺️
Crazy. 10 years ago, I did a practicum at the Alber Einstein Institute in Hannover under supervision of Dr. Aufmuth, where we were able to look at and participate in some laser testing for Lisa. Back then I did not really understand the value of this project. It's incredible to see it coming closer to getting out there. Loving it. Now I am an Artificial Intelligence engineer and sometimes think about where I would be, if I had actually chosen a physics career. I'm really happy to be alive during such exiting times. Can't wait the hear the first heart beats of the universe.
We have neutrino detectors before gravitational detectors. So, our knowledge was NOT just from light.
When you mentioned that LISA was a joint ESA/NASA project, it brought a tiny tear to my eye.
These are glimpses of humanity of the future: no nations, no religions, no other forms of stupid tribalism - just a unified species deeply fascinated with the universe and life.
Rootless and uninspired, is exactly how the ruling tribe want the masses,and promises of science based utopias, is how they'll fool the masses into giving up they're freedoms!
@@Sandwich13455 You high, bro?
@@i_am_ergo slightly
You do understand that scientific advancements are often made through asking philosophical questions, brought forth by these 'stupid' cultures and nations? You're describing a world in which everyone is basically the same 😐
@@a1r592 One, tribalism is by definition more destructive than constructive as it divides people into groups and pits them against each other for no reason. Two, you don't need ancient irrational values to ask questions like, "How does the physical world operate? Is quazi-eternal youth possible? How do we beat the speed of light and escape the Solar system/local group?" You don't need this old stupidity to ask the question "Why?" either, because the question is self-evident, and the answers cultures give are all rooted in ignorance and false.
As for your last statement, we ARE the same. We ARE born equal.
Great Job bro!!!!!
THANK YOU FROM LISA
I Loved LIGO and now LISA!
Another absolutely brilliant video! Thanks as big as the observable universe and beyond 👍🏼
Sadly my home is too small to put up more framed posters...
Both The thumbnail and the video are amazing 😍👍👍
Thanks! You are very kind! Full credit to the NASA Goddard Space Flight Center who made the full simulation of colliding black holes. There is a link to their video in my description.
Awesome!
That sounds a lot like the "drag free orbit" pioneered by Gravity Probe B. I wish you had elaborated on that. You ought to look into it for a future video.
I remember first hearing about this on an episode of Nova back in 2004.
I wish it would launch sooner, this is awesome
This is Awesome
Totally for, and looking forward to, I hope, LISA, however 15 years is a generation of Astrophysicists / Astronomers away. Love the update and enthusiasm, but I'm looking forward to the new neutrino detector prototype, using dual phase liquid and gas forms of argon, and it's happening now! Love your channel.
Very cool, putting 2034 into my calendar.
MORE VIDEOS PLEASE!!!
This is so exciting! Ahhh why do we have to wait 15 YEARS!!
👷 Thank You!
I do not understand, but very interesting!
Awesome br😎ther
How are the LIGO and VIRGO detectors able to differentiate which gravitational waves come from outer space and which ones are just interferences from the outside (for example, as you said, a truck passing by, etc.)?
UPSC 2020 Asked about LISA
Since subbing a month ago ,this is my first notification! Dammit you tube (shakes fist ).
wow we REALLY need this mission to work.. literally if it doesn't.. we got to build it again until it does :O
What I don’t understand: The thing these GW detectors measure is the distance the laser travels (to 1/1000 of a proton diameter). Don’t they then have to then also make sure that the distance of the three satellites and their relative movement to each other is at least that certain? How can you make such fine corrections with thrusters?
Why would we not be able to "see" past the edge of the observable universe? Gravity waves are not light and therefore not constrained to the speed of light, hence would it not make sense that we would be able to detect past it?
What program/application do you use for animating?
What would it take to obtain a picture of the cosmic gravitational background?
We're going to see what's beyond it! We're going to see what's beyond the CMB!
2034. 50/50 I will still be around by then, even if all goes well for next 15 years. :(
Well, yes I do like watching scientific research which would show hope; it's what we all need. Replies welcomed.
It's official - LISA will be built.
ESA just published the commission. Now need to find someone to build it.
How will the mictothrusters refuel and what about micrometeroites and dust and stuff causing false readings on the lasers?
please make the map of astronomy
0:51 RIP neutrinos. We definitely learned about the sun from neutrinos. They confirmed estimates of the rate of nuclear fusion in the core.
www.symmetrymagazine.org/article/dune-scientists-see-particle-tracks-with-dual-phase-technology Neutrinos are not quite done for yet.
0:51 - You forgot about the neutrino astronomy (and other non-electromagnetic astronomy).
This concept was asked in UPSC exam 2020
Question I see that LISA is made of 3 Satelites, wouldn't 4 be better, especially if they'd be organized in a tetraeder positioning? Is 3 sats enough? Why is 3 enough?
I understand 50%,but like your vedio 💯%
A map video please!!!
It will be sitting at one of those Lagrange points, right?
vote out everyone that doesn't want this as close to the initial 2015 projection for project launch as possible... worldwide vote them out!
Do we hear or see gravitational waves? I think it's more like hearing; the waves detected by LIGO are in the audio frequency range, and it takes at least two detectors to get any idea where they came from. But dolphins, bats, and the telescope that imaged Pōwehi make the dichotomy fuzzy.
Neither they are incredibly subtle. Imperceivable by any organism.
You should make a map of philosophy!
Damn this is sweet as
Are gravity waves Doppler shifted?
Will LIGO and LISA still be online in 2034?
It sounds like LISA is the most exiting study ever and comparable to James Web. If it gives us a new picture with new physics then that's great but to se an infant universe then Wow!
where will it be located?
You said that sapce is much more calm than on Earth but that's not true at all... what about solar wind and deep cosmic radiation? How will LISA counterpart those forces to stay in precise position (I assume precision level must be on subatomic level).
Procrastinating doing my cosmology homework with this video. I’m such a nerd
Will we need 2 Lisa's?
#DomainOfScience.
Can you make a map of Economics and map of Accounting.
Please make a video about DESI! They just got some results out.
7:15 the stupid me not knowing what hubble telescope did be like.... uhmmm, ohkayyy!!
James Webb all over again?! And here I was thinking I might have to settle down for the science finally due THIS decade!
Has it's name been announced as 'evolved lisa'?
And is it related to Pathfinder Lisa?
Upsc been really pathetic to candidates
@@shivanipandey3019 you must be preparing for UPSC ,did you get question related to it right ,and how did you do in prelims .
@@swetakumari4747 is lisa and eLisa same?
light can actually travel trough a black hole
My dumb ass seen this and forgot and i thought they had already launched it but i could only find the ground observatory
Big yup
I'm just here for the dreamy professor.
Me too!
Are you men?
@@Sandwich13455 yeah?
Will it be able to tell if gravity came late to the party known as the "Big Bang?"
Why just a triangle
not a tetrahedron?
2034, haaaa i wonder for how long its going to be delayed till
5:54 is PathFinder, not LISA? PathFinder have accelerometers parallel, LISA not
Something is fishy about detection of gravitational waves. We measure length by observing matter, using light.
The assumption here is that matter is stretched and compressed, but the wavelength of light is not. Why? Isn't light residing in space?
Also, a completely equivalent view is that space is unaffected, while the wavelength of the laser beam changes. My guess is that this is the electrical engineer's preferred interpretation.
Why is the former favorized over the other?
"The assumption here is that matter is stretched and compressed, but the wavelength of light is not"
You are completely misunderstanding something, there is no such assumption and nobody is measuring compression or stretching of matter. That's not how you detect gravitational waves with an interferometer, this is how you do it en.wikipedia.org/wiki/LIGO#/media/File:Gravitational_wave_observatory_principle.svg
This video is of Evolved LISA or LISA.
LISA pathfinder is LISA pathfinder and not LISA.
whatever happened to the we can get to the moon by the end of this decade attitude? We can get to the edge of the observeable universe for effs sake!😎
so expanding space-time has no effect on gravitational wave? Unlike light getting redshifted.
Maybe it dose? We don't really know much about gravitational waves, we have much more experience with light
Of course it does, it behaves exactly like light in this way, that's why it can be used to independently verify Hubble's constant.
@@aleksandersuur9475 what evidence do we have of this?
@@connorschultz380 If anyone has tried to experimentally verify it, I don't know about it. It might be more complicated than simply correlating distance from event luminosity to distance from measured redshift, the assumption that it does redshift must be written in pretty deep so just doing that might not tell you much.
But the reason we knew to look for gravitational waves to begin with is because general relativity predicted they must exist and described what they are and how they behave. And yes, according to GR they must blue and redshift like everything else.
Redshift is not just a light thing, it's a geometry thing, it doesn't apply to just light, it applies to everything. All particles including photons and gravitational waves too.
I guess LISA will verify this experimentally when it will be used to independently calculate Hubble's constant, if there is no redshift in gravitational waves then it's not going to work and come up with value of zero. I very much doubt there will be any surprises of that nature
Upsc prelims 2020
2034: the same year the James Webb telescope will finally launch.
Lisa, eh? Talk about Weird Science ....
Unless we start spending wayyyy more on space exploration we won't be able to launch this by 2034..... how sad is that. We're completely capable of doing something that we aren't.
This is some expensive mission, hope it is not the waste of money.
These masses inside the crafts will differ with altitude it could lead to some confusion.
why it takes so long till 2034 to be launch? :(
and there's a test facility in Germany where they invented all the technology for the American an Italian interferometers
I'm 25, I'll 39 when this launches 😳
5:08 I want to throw up just hearing that, just think of how creepy and powerful the assembly of that information will be, how unreal and how much it's going to show us..
Who is here froM IAS prelims 2020 ?
This is lisa pathfinder or evolved lisa
U guys have been fooled by that upsc test. They made up that option 'evolved lisa' to fool the students. It puts pressure on you. It's a classic trick to confuse MCQ test takers.
@@nikhildev4490 I was not fooled. May be others were. I selected right option
@@regualtorybodyexam Its seems that the answer to that question is 'evolved lisa' which will be launched in 2034. Lisa pathfinder was a 2015 mission to study feasibility for the evolved lisa project.
james webb ?? , lisa is bigger than hubble revolution
Yeah, supercool and everything. But what I would like to know is why the bloody hell does it take 15 more years to launch LISA when Pathfinder exceeded expectations already 4 years ago?
Cost of spaceflight is not a factor if you compare it to stretching a major project decades longer than it needs to be. Building the hardware and launching it are marginal costs compared to keeping teams of top grade engineers and scientists on payroll for decades. Hardware only costs the man hours put into it, so you better use these manhours efficiently, I don't see that happening on a two decade long project.
what's the climate forecast for 2034? i think LISA will be last thing on our minds.
Hi, a few doubts if i may;
1)U said that LISA will have an arm length of 2.5millon km's. How far away is it going to be placed frm earth & will it be in solar orbit?
2)Although, as u mentioned that there are multiple events i.e.(sneeze, passing truck, siesmic vibrations )which can hamper the accuracy of LIGO, the very fact that it succesfully measured a vibration 10,000th of a proton(as mentioned) from a source 300million light yrs away says that it IS accurate AND sturdy enough....On the same lines, as LISA (3 spacecraft moving in tandem) will be in space with a 2.5 million km arm length, there will be many more factors affecting its accuracy(Self technicalities, cosmic impacts, radiation pressure & various unknowns as space). How do they propose to overcome these known & unknown factors.... Read expense-effort-multiple unknowns-Unable to rectify if affected......Still i guess thise r smart people & will work out something, what with the amnt of knowledge to be gained & new physics developed...Thk u.
I can hardly wait for the gravitational detector space launch thing. Then maybe we can make our own black holes for some reason, maybe it might be like tossing a handful of pennies into a spinning air plane propeller in slow motion.

How you can do this to us?
