- Marcia Bartusiak joins Kip Thorne, Laura Danly and Rainer Weiss to demonstrate how two observatories on opposite sides of the country, called LIGO (Laser Interferometer Gravitational-wave Observatory), may open a new window on observing the cosmos-one based not in light but in gravity. Scientists have embarked on this joint experiment, seeking whispers of far-away violence-like the collision between distant black holes-rippling through the cosmos. It’s taken nearly a century, but technology has finally caught up to Einstein’s brilliance. His 1916 General Theory of Relativity predicted the existence of gravitational waves-undulations in the very fabric of space and time-and LIGO researchers are now poised to detect them.
The World Science Festival gathers great minds in science and the arts to produce live and digital content that allows a broad general audience to engage with scientific discoveries. Our mission is to cultivate a general public informed by science, inspired by its wonder, convinced of its value, and prepared to engage with its implications for the future.

World Science Festival : is black holes reflektet by the gravitation Waves ? :2) how frekvent is supernova registrert ?
Infinite spacetime has no beginning or ending.
Gravitational spacial distortion bends the path of light as you are probably aware, it also distorts the frequency of light emitted from super heavy distant galaxies.
Gravity from distant galaxies has a redshift effect on the frequency of light they emit in the same way that gravity can bend the path of light from a light source behind the gravitational field.
Dark energy is an illusion caused by a spacial distortion caused by the gravitational fields of the distant galaxies emitting the light, there is no mysterious energy accelerating galaxies away from you.Hence no cosmic acceleration, no dark energy causing acceleration, no unaccounted for dark matter, and certainly, no big bang. This universe is eternal, without beginning or ending. Cosmic background microwaves are but distant galaxies who's light has been gravitationally distorted beyond your visible spectrum.
Galaxies continually exchange and recycle energy and birth new stars out of old dead ones for ever and ever.
How do you think light escapes super heavy distant galaxies with its frequency visually unaffected by spacial distortions?
Someday sapien's evolutionary decendents might survive travel to distant galaxies and discover the return trip doesn't take require extra travel time, as no acceleration is actually occuring.
That is unless your craft is destroyed by a violent war mongering species, leaving you marooned on their backwards hillbilly planet where its custumary to torture other species before slaughtering and consuming them as cheap food.

Don't beLIEve in lies! The World has no "south pole" and no civilian planes are allowed to fly over the World's circular/rounded Ice-Wall ring which surrounds the general/publicly known World, no nation is allowed to officially own/take over/colonize the region, no civilian has full unrestricted travel access there, nor may any civilian entity locate/set up any places for residence/business there,... (what is falsely/wrongly referred to as the "south pole" - as bLIEved by indoctrinated, foolish, retarded, ignorant sheeple)
These old shows is worth my RUclips premium account alone!!
And they both won the Nobel Prize for these discoveries. Congrats to Kip and Rainer, fantastic work!
And about 1 year later, LIGO detects gravitational waves! Science is friggin amazing. :)
My support and respect.
Watching from Nigeria 🇳🇬
These World Science Festival talks are like a breath of fresh air in the otherwise cesspool of crap produced by the likes of National Geographic, the Discovery Channel, Neil Tyson, etc.... Thank you so much for this!!
I agree
I agree! I don't like that you put Neil Tyson in the same group. He is amazing!
Glad you mentioned Neil Tyson. He's just overrated and full of noise
This was the best conversation i've ever heard! So inspiring! Go Gravity Waves!
amazing panel + great discussion. Go Gravity Waves!!!!
Thanks for this fantastic Nobel show...
I enjoy this "Shows" immensely ....so few of them going around.....some times one is to busy w/every day living that one loses track of the fact that stuff like this is out there .....ready for us to enjoy it.
I like to thank everyone involved on developing these programs and those who ensure they get to us....
Thanks!!......Gracias!!
fabulous discussion. also... do a shot every time kip thorne says ayuuhh
I was literally thinking the exact same thing!
Just casually sat here being fascinated by the whole discussion, then hearing that a few times or so I burst out laughing. 😂😂😂
Lol ya true. Wish I was younger early 20s. I would play that game. Amazing people. Amazing gift to humanity. Trying to understand the UFOS so I watch all this. Lol
Learnt so much. All participants communicated brilliantly.
Thank you. Pray you all are safe.
A trip to New York will be planned. Thank you for explaining.
I wish I could be a fly on the wall during conversations of this sort, between people of this sort, behind closed doors, and over a glass of wine.
hahaha dude u high af
Nope. Just enjoy listening to smart people. I like to ponder. They ponder better than me.
RyanBurke I wonder what best guesses and personal insights they'd have when they don't have to be on the record.
Here you're getting their findings. None of their imagination. I'd like to hear humanities vanguard speculate. I like to talk about what a higher dimension would be like. I like to talk about what's beyond the even horizon. I'm just some dumby. What fun things would they say? How different would it be?
AnonaMousetookmaname tinyurl.com/kynttc4
February 2016, Gravity waves discovered, there might be a planet 9 somewhere beyond the Oort cloud... we live in an amazing time period...
+Wim V (ilGatoNero)
That would be NOTHING compared to the head-spinning reality we'll be able to uncover now.
I liked this host, she was very informed which helped the presentation flow! great video thanks
51:37 Pulsars pulsating hotly
12:10 it starts. :)
And I finish first cuz I got reputations for my stolen goods and services and still paid you ,@#$ers another means it out of love when she says take your food to your room I'll never give you glass or dirt or rocks to play with again.
Interstellar directed by Spielberg? How am I supposed to trust people on this discussion now?
+Jagjit Singh
He is mixing a lot of crap into what he says.
This discussion happened in 2010 when Spielberg was still attached to the project
The science fiction novel Macroscope by Piers Anthony predicted this in the 1960's. Fantastic book for those interested in gravitational waves and what they can tell us.
Thanks from Denmark
Wow you guys did WONDERFUL. Thankyou for this !
Thank you. Amazing. Thank you.
Observing this conversation from here ( Earth ) I can see ( notice ) the importance of detecting the trajectory of bodies on collision courses with earth and the connected surrounding structures to possibly cause the collective focusing on effecting those trajectories in order to avoid future cataclysms as have clearly happened to earth in the past . A collaboration of fields toward the goal of the continued survival of earth and it's stability within these structures is Paramount.
dimensions are caused by the scale of the objects, not by time-space-gravity. because particles form and behave differently in quantum and macro scale. they are in a different perspective and thus they have different time-space-gravity perception...ok, I'm talking shit..probably :-)
I love world science fair it’s so interesting, informative, intriguing and mind blowing especially for someone who wished they paid more attention in school. But why don’t they rather than a group of experts sitting around explaining things, sit around and create new theories and new hypothesis and use utube and the global audience to help rather than comment. Let’s find more Einstein’s
there's things that go lot faster than light or gravity but we need to figure out how to detect them. How?
Ligo, you're badass.

I love discovery and how layered/multifaceted each new realization is.

Good on him... mate.

@@SayNOtoGreens global warming? Please .. One person is speck of sand in the universe...this world might not be forever! It's an other dimension between space and time.
What is Kip Torne tick called ? he keep doing strange sound like hahaha... I am sure it's involuntary it was bugging me at time and make me smile at other time.
Sounds like "ok" to me
Tourette syndrome?
What Kip Thorne say at 57:14 ? I can't understand what he say.
he said "they're a lot more gullible"
I tend to believe that since light is so extremely expansive, & we are so comparatively minimal, shrinkage might not be sensed.
"AeeEe".
that's the sound of two kip thornes merging
Damn you for making me laugh at that. Damn you.
Is it Tourette's Syndrome? It's cute. Chicks probably dig it.
@@noodoo19 it's just his thinking noise. Some people use "um" or "like", he uses that. I like it a lot better than "um" or "uh."
@dirac bracket its not a condition dummy lol, its just his way of saying "umm".

+Tony Clough Theoretically, right? Imagine that we built many refined detectors and network them... to approach that level (or an impressive level) of spatial resolution... We would have a view of the Earth like no other.
aaeeuuhh?
Aaaaeeuhh!
I am very much looking forward to the (LISA?)..i I think it's going to be called? The very much bigger detector set out in orbit? I don't know much about it but the implications seem pretty exciting!
Can I say that we are thinking outside the box?
Damn, Duke Nukem was around in 1887? That's dope!
I'm confused by what they were talking about around 44minutes with the pulsar and neutron orbiting each other. Can someone explain why gravitational waves taking energy away from the two stars would cause them to come together? Is it that the farther they are away from each other the more potential energy there is so that as the gravitational waves take more energy, the less potential energy and thus less distance between them?
I took physics yeeeears ago so excuse the stupid attempt at trying to understand this lol
Guy in the middle sounds like he’s doing a Jeff Goldbloom impression.
I mean on the title so you can see before you click on them how old they are.
Exactly what I already knew our sounds abd musical tones came from the black hole universe
We really need dates putting on these lectures. Stuff goes out of date? Ligo has detected gravity waves now.
In the description Dude.
Totally filmed in Arizona lol
What is traveling through an electrical wire is it electrons or what is it?
Yes, from what I gather it's electrons moving through a copper (or other conductive metal) cable that we think of as "power". This same concept is what makes batteries work where combinations of certain acidic chemicals and conductive metals produce a steady flow of electrons. When it comes to fiber optic cables we can only send information through them in the form of pulsing photons (light), and we can't send electrons aka "power" down a glass fiber optic cable because glass isn't conductive for electrons.
Electrons protons photons neurons static energy synthesis
The distortion of space time is an effect caused by gravity, but it does not tell us what gravity is.
What if the wave comes from directly above..? the detector won't work..
This look like Michelson-Morley ether experiment in 1878.
The principle is very similar indeed. They are looking for a different specific thing but it manifests in the same observable effect they hope to detect and measure. Other than the much better equipment and smaller effects, this is pretty much the same idea. In fact, given that both effects are based on the same Relativity principles, one could even argue they are looking for basically the same thing - space/time dilations.
The only relevant comment & reply in the video's entire collection , like a blip in a sea of noise 👍
If you missed it in this discussion, no gravity waves have ever been detected as of the discussion date, and not as of today July 8, 2015. Although General Relativity is undoubtedly reliable, I don't see that the predictions about spectacular interacting neutron stars necessarily is. The fact that there has never been any lucky detection in lower sensitivity detectors, and the lack of any possible verification for the predictions concerning neutron stars, make it too possible that the improved sensitivity detectors will never see anything.
+Kenneth Florek Always good to be skeptical...I am starting to have some confidence in gravity waves but the damn universe has fooled me before. The thing is that if they are shown to be wrong then we have a huge field of physics to start exploring all over again..and that can be wondrous all in itself
Keith Durant
I don't see a reason why there might not be gravitational waves even under Newtonian gravity, so even for skeptics of General Relativity, which I am not, there is no particular reason to doubt their existence. That doesn't mean there are any waves large enough or close enough to detect.
I recall that the grand conjunction of the planets was thought, by some fringe people, likely to set off earthquakes. But some one pointed out that the gravitational attraction of a person a few feet away from you was stronger than from the planet Jupiter. So it is a lot to believe that events, so immensely more distant that it makes Jupiter seem close, are going to be strong enough to detect by gravity.
Kenneth Florek
The question is how will it tie into quantum field theory...gravity is like a photon..it travels at the speed of light and is therefore timeless in its transfer so is it a wave particle duality in itself where if you spank the vacuum hard enough you can make one..:)
Keith Durant
I expect there won't be anything noteworthy any time soon on whether gravity finally fits properly into quantum theory. The waves LIGO is supposed to measure come from General Relativity and don't depend on a quantum theory of gravity. So if LIGO fails to see any gravity waves, it won't invalidate a quantum theory of gravity.
Never understood x / per second / per second.
Understand the first per second, but no clue what the 2nd per second refers to.
X / per-second / per-second refers to continuous acceleration over time.
For example, if an object (on earth) would fall 32ft / per-sec / per-sec
then it would accelerate by "1g" and fall 32ft. during the FIRST second.
This 32ft/sec is the AVERAGE speed during that time interval; but the
exact "momentary" speed was only 32ft/sec in the middle of that second.
If the object was stopped/still/stationary at the beginning of that 1sec,
and it was accelerating (ie:falling) during that time During that second.
During each second the object falls, it CONTINUES to accelerate, geting
FASTER at the rate of 32ft per second. If an object were falling for ten
seconds, then it would be moving over 320ft/sec at the end of that time.
(over 200 mph, and over 320kph)
These numbers are NOT adjusting for air friction. Since things are seldom
falling in a vacuum... what happens "in real life" is that wind resistance will
increase as you fall faster, until force of air equals the objects weight, so
that object will not fall any faster. This "maximum falling rate, because of
air resistance" is known as "terminal velocity" for an object. For a person
falling during a parachute jump, the terminal velocity may be 120mph,
until they open a parachute... which increases wind resistance, perhaps
slowing the fall to 15mph until they land.
Wind resistance & terminal velocity is also why a leaf or feather (in air) falls
more slowly than a rock... but small rocks and big rocks would fall at the
same speed (having same density/shape/ratio of air resistance)
If an object were thrown UP at 100ft-per-sec, then gravity would still pull
on the object, in the opposite direction, and it will take about 3 seconds for
the speed to DeCelerate to a stop, and then begin to fall.
These descriptions use Newton's description of gravity (not needing relativity)
but does answer your question accurately. (valid in nearly all "real world" cases)
BAM!!!
How can this communication be funded. What is the purpose ?
46:10 I hope those colleagues who asked why she studies things that don’t exist apologized after LIGO observed actual gravitational waves
The only thing mathematics and physics cannot predict is who Hollywood will throw as a director onto a movie. Spielberg would have done such an amazing job of interstellar instead of that drawn out mess we got instead.
+aaron versionwo Spielberg is a FAKE specialist.
Réal Morrissette
And can I see your IMDB page please?
+aaron versionwo If I have any, I will be glad to show you! But first, I'd like to know what is a " IMDB page"?
You would know if you knew anything about movies and directors... at all.
I do not doubt the talent of Spielberg. I wanted to emphasize that movies are NOT real life. Movies are fake things and hypocrisy.
Sometimes its gone den its going back again
Can anybody here point me in the direction of a good wormhole video?
How many famous people must we suffer . There is a goal here.
The "double slit experiment" is the common cold of the physics world. It shows light functioning as both a wave and single photons, which can't be explained. It tempers my excitement about a lot of these theories.
Where's John Hockenberry.?
Glad he wasn't here.
It's ALWAYS better when a professional scientist or science writer introduces the panel. Can't stand the constant lame jokes from the disc jocks!
The first time I looked at the sk I thought it was a roof over the world and the stars were holes in that roof iMade sense because that's how the rain gets in
One day blink of an eye,time on this gravitational matter of this dimension! One day -the other dimension? Celestial body-no gravity! 1.000 years to maybe 0 time.
einstein's theory of *aaaeeh*
We need too see just how micro we can go as far as instrument detection s that can sense the whole compilation of data that is still being processed .Time is of the most important thing in finding the right avenue My experience s in gravity well is there is a spike the a rapid decline in the pulses yet in stace the decline is not there some thing is feeding it out there from the shielding earth field so hard to get data from the clutches of these holder of data
Marcia is slightly irritating when she cut Rainer, thinking she is very funny and brilliant.
Yep
This lady irritates me as well. Being a science writer always rewording and commenting on scientific works seems to have her mistakenly thinking she has more than her very basic grasp of astronomy and physics topics.
who's to say Aristotle was talking about Terrestrial objects?
Fun & Games
But yes the druids of cosmic ancestors will appear to us in the plink of an eye!
It would be funny if the start sounded like a reverse black hole creation.
(white hole), also i love to see Laura Danley narrate more videos, she is so clear in her message.
Advanced LIGO's First Observing Run Comes to an End
News Release•
January 12, 2016
On January 12, 2016 at 8:00 a.m. Pacific standard time, the advanced
LIGO detectors located in Hanford WA and Livingston LA completed their
first and long-awaited “observing run”. Dubbed "O1", this full-on use of
LIGO as a gravitational wave observatory was the first such application
of LIGO's interferometers after undergoing a 5-year redesign and
rebuild to greatly improve LIGO's ability to 'hear' gravitational waves.
This first official use of the interferometers as a unified scientific
instrument lasted 106 days. In that time, the Hanford and Livingston
detectors logged nearly 1100 hours of tandem observation; times when
both interferometers were simultaneously locked, thereby operating as
the world's largest gravitational wave observatory.
LIGO will begin a second observing run ("O2") later in 2016 after
engineers get a chance to examine the interferometers’ performance
during O1, and to further understand the intricacies of this incredibly
complex and sensitive machine. O2 will commence after the first of
several planned enhancements to the interferometers (designed to
increase its sensitivity yet again) are completed.
LIGO management thanks all of the observatory operators and technical
staff who worked around the clock during O1 and especially over the
holidays. Since Nature could throw a gravitational wave at Earth at any
time day or night, searching for gravitational waves is a 24/7 endeavor.

Excellent stuff - Do wish the presenter interjected a bit less.
Same thing happens in almost every show from WSF, no matter who the presenter is, it does seem kinda rude and drives me a little crazy but they’re still always awesome presentations
Kips `warble` is merely the Doppler effect. So forget about it and enjoy the man.
Actually, the hammer and the feather don't technically fall at the same rate in a planetary gravitational field, all things being equal. It's just that you would need to inspect the 27th, or so, value after the decimal point to see the difference. M1 in the equation is the earth or moon and compared to those bodies M2 being either the hammer or feather is essentially, but not actually, the same mass.
Marcia Bartusiak is an excellent journalist
Perhaps, but she is not a very good moderator.
Gravitational waves should never be called "gravity waves for short", gravity waves are a phenomena already defined in fluid dynamics, and sometimes seen in clouds.
Next step "gravy waves" , and then simply "graves" :o)
Lest y'all think that gravity waves can be heard... NOPE. It's one possible presentation of the data.
Receive the accolade and the paycheck .
great show, but when we finally get to the last panelist the host talks all over him. rude
ik shut the fuck up,
She just likes people to know who's in charge, and she is very generous about it.
Albert was taking a piss. Clearly speed is measured in defunkt from this perspective of in congruency.
Why do moderators think they have to behave like children's entertainers?
{:-:-:}
That sounded like a motorcycle
The shadow can bend to, how about d shadow of the earth and the moon?
When black holes merge it sounds like Mario gets an extra life.
Oh going to test me again
torsion yo
I'll get out the obvious and obligatory stuff first:
Andrea Lommen is brilliant, and an overall phenomenal person, and she also happens to be right about gravitational waves.
And holy hell does she have nice legs. Wow.
You should see Kip's.
As people already stated in the comments:
- 12:31 freaking minutes of introduction, wth?
+HomeWatchViewer Typical of the World Science Festival colloquia, I hate to tell you. I doubt that they will change it.
.'💕'
how did all this dirt come from the BIG BANG? all these planets and all this dirt came from nothing? where did it come from?
Is Tim the Tool man Allen paying royalties to kip for catch phrase lol
Freeman Dyson has shown an equation proving that LIGO will never ever detect gravitational waves/gravitons.A waste of money and a huge mistake on behalf of the folks behind the project.
Ops 😱
+BrodyLuv2 Time to eat those words and for Mr Dyson to rethink his equation.
Johnny Chunders
Still holds true for the detection of supposed Gravitons.
Chewing on Gravitational waves.
+BrodyLuv2 True. Gravitons are just a guess. But that's the method. Guess, test then verify. So they've found those waves exist as predicted. Big deal and well done Einstein. He was right.
But if the loudest gravitational noises in the universe (colliding black holes/neutron stars) sound like a sparrow farting on our most sensitive instruments what hope is there for gravitational astronomy?
Johnny Chunders More sensitive instruments
Let's all giggle and talk like children.
organized religion was born from ignorance, and you say they are childish.
Giggle about gravity waves and they have no idea what gravity or dark matter is. If the big bang doesn't work just add inflation and all the simple will believe.
Hi
Do i pass?
a great host :)
How? The interrupting cow screwed up everyone's rhythms asking questions too early. She didn't add anything, and would have been best to leave after the intros. Great talks, loved the ideas and props
Kris Driver
Be civil please
Anoop Pawar the cow portion was in reference to a knock knock joke btw. I stand by my comments as positive criticism. I'd like to not have the discussions curtailed and progression of a thought be explained sequentially in future sessions in the interest of clarity for everyone. Being nice doesn't help for better future talks.
Yeah but it does not cost anything to be nice does it?
lol no but it's not productive in this case, I don't think. I'm not judging her a person, I'm sure she's a spectacularly wonderful human being. I'm obviously not a troll just spouting random bs to piss people off. Disassociate your feelings from critique, it only adds barriers to the learning process.
Lest you care about cataclysm. Then we shall speak.
I don’t know about u guys but I fly with blazing stars and I do it for free
I’m honestly not a conspiracy nut but watch the hammer move up in the astronaut s hand, please watch.
He gripped it, made an upward motion with his hand, let go, 2nd law of motion, hammer moves up slightly, he catches it again. The reason it looks so weird is because of the reduced gravity he made a really tiny motion with his hand that translated to a larger effect in the hammer's motion, hence it looked weird to you.
Why the fuck she does not say right away that the difference is that there is significant air resistance on earth so people don't get confused.
Physicist always fail to tell people air resistance is significant the basic reason why people were so confused for thousands of years...
I play tennis and i can literally make a ball curve 3 meter side way with air resistance alone on the short distance of the length of the court.
A sniper as to take account of the wind to be able to hit is target and I am not in the army but I am pretty sure modern artillery take into account wind otherwise you could not call it modern artillery.
Coming from the episode "Beyond Beauty - the predictive power of Symmetry" , this moderator's outfit is extremely _wrong_
24:50 finally a Man allowed a few moments of severely interrupted talking - sheesh what a crappy episode
That host gave me little cringe
Many African did for you to say you can are your founders
