Boy oh boy this video is super relevant now! Didn't take 20-30 years to observe these gravy waves. Just 5.
:D
+Ch3mG33k Mmm.... Gravy waves maybe I could use that on my Roast Beef
Perhaps you misunderstood him? He said we might be able to observe it directly, talking about the merger of two black holes, using detectors based on detecting gravitational waves. We have yet to get there. His estimation for this isn't irrelevant at this point.
+reckneya as far as i know they've been detected
+reckneya The merger of two black holes has been observed directly. The two ligo observatories detected them in September of 2015. We have "gotten there".
"I have a friend who’s an artist and has sometimes taken a view which I don’t agree with very well. He’ll hold up a flower and say "look how beautiful it is," and I’ll agree. Then he says "I as an artist can see how beautiful this is but you as a scientist take this all apart and it becomes a dull thing," and I think that he’s kind of nutty. First of all, the beauty that he sees is available to other people and to me too, I believe, although I might not be quite as refined aesthetically as he is, I can appreciate the beauty of a flower.
At the same time, I see much more about the flower than he sees. I could imagine the cells in there, the complicated actions inside, which also have a beauty. I mean it’s not just beauty at this dimension, at one centimeter; there’s also beauty at smaller dimensions, the inner structure, also the processes. The fact that the colors in the flower evolved in order to attract insects to pollinate it is interesting; it means that insects can see the color. It adds a question: does this aesthetic sense also exist in the lower forms? Why is it aesthetic? All kinds of interesting questions which the science knowledge only adds to the excitement, the mystery and the awe of a flower. It only adds. I don’t understand how it subtracts."
- Richard Feynman
Robert Ruhland science is beautiful
It is so interesting to listen to this again now that it has been observed.
the only thing I've liked less because I knew more about it was a hotdog
+Kille rSatellite you play minecraft too much to understand anything
So true ha ha lol.😃
6 years later and we have evidence of gravitational waves. cool
5 years later*
Hoo Dini 1 year later* (they were first detected in 2011).
Kamran Younis no evidence tho
3 more and we have an image of a black hole, gravity waves from two neutron stars AND images of it too! ;)
So... the universe is beyblade?
***** (yes)
Yes George, we all live inside CARTOON NETWORK :]
@Ozymandias "the" King do you know from XP
Offfff no sense of humor.. Anyway
George I FINALLY GET IT NOW :D
Gravity waves were finally detected!
Yeaaaa boiiii
+johnnyq1992 *gravitational waves
Gravity waves were detected back in the 70s and a Nobel prize was awarded for it.
But the circumstances in 2011 were more than questionable
One of my favorite things about my scientific education is the fact that I still look at the world with childish awe and countless questions, but I can now begin to answer those questions!
science doesn't take away the beauty of nature at all, enhances it, makes you realise how amazing it is.
i find nature beautiful and amazing, like how trees make negative pressure to get the water to the top of trees, i find that crazy. or how a pistol shrimp can create a sonic boom under water! nature is amazing. see ya.
my my what a cynical/negative douche. you must be real fun to be around! again, see ya.
***** doesnt take much to know you are a douche. You said it, it's their belief. So stop imposing your pov on them and go by your way in your not so amazing natural world
***** because you think your pov is way more consistent? Smh. You are so stuck up in your beliefs its probably pointless talking.
Yeah i came off rough. Sorry. Still understand the point.
Scientific knowledge of a beautiful phenomenon simply deepens the experience, and can lead to appreciation of beauty that lies beneath the surface. (just ask an arachnologist!)
As a sommelier uses his knowledge to further appreciate wine, so do sports fans get involved in the fates of their favourite players, and so do scientists getting stuck into their favourite subject material.
People used to live their entire lives within the same paradigms and perspectives, and now we make major discoveries and advancements every decade. And you get to hear about them in detail from knowledgeable people for free on the internet!
What a time to be alive.
Haha your question about the Sunset was rather tempted to see if they would answer differently, but they struck with beautiful answers :) I love these guys they are amazing. Thanks for posting!
Within 20 or 30 years he said... :) (Go LIGO, WOOH!)
9 years later we took an actual image of blackhole, maybe 1 more for a collision photograph
This series is one of the best on youtube. Thank you so much :)
As a musician, I can't help but think about the particular mechanics of a composition I might be listening to. This doesn't detract from any appreciation I may have for the piece. It could even enhance the experience for me, especially if it is a particularly beautiful piece of music..."Prelude to the Afternoon of a Faun" by Debussy, for example.
I'm having hard time trying to imagine singularity 'spinning'.
Just twiddle your fingers together. Like that.
That's why it's a ringularity lol
Anyone here watching after the discovery of The Gravitational Waves?:)
No, noone.
these are fantastic videos. thanks for posting them.
These videos are so good there addicting.
keep up the brilliant work
I don't understand this notion that is apparently somewhat pervasive; that people think understanding more about life makes it somehow less enjoyable or less interesting. If I had to guess it comes from ignorant arrogance; that so feeling that we need to be somehow important in order to live a happy and meaningful life. Since science is proving again and again that humans are not the least bit significant for anything (at least like people used to think).
I'm so thankful I don't seem to share this foolish notion (anymore). When people say this depresses them I just laugh. I'm living happily and enjoying my wonderfully unimportant and insignificant life, and I wouldn't have it any other way.
In my entire live, I have yet to see the Milk Way. I have tried, but it is difficult to find and get to some place dark enough for that.
***** Try to find the darkest place possible, most rural area.
Here in Idaho, even in small towns like Pocatello where I grew up, fortunately because of the mountain ranges and the towns are actually fairly small and close to wide areas of absolutely nothing but either desert, marshes, or forests with mountains I only had to go about 30 miles from town to see the galaxy.
Try a mountainous area, they help keep out light.
Here in Boise, I have to leave the Snake River valley area into the mountains. Then you see everything. North or south, just 30 miles south or 60 miles north into the mountains works.
jmitterii2
At some point, I want to travel to some place that is truly dark where not even the bottom of clouds are lit by city lights. I want to do this on a clear moonless night so that the only persistent lighting would come from distant stars. I probably wouldn't be able to see much, but it would be interesting to stand in a landscape lit only by the light of the universe.
The best bet for this is probably in the ocean far from land, like at least a day's travel.
Ask one of those scenic flight pilots to take you up at night.
I must say that I always thought the area that I live in is too light-y for me to see it, even though it's pretty remote. However, I've been proved wrong this summer when the lights went out for a few hours and I got to finally see it. Despite my poor sight, I could still easily make it out and it was really breath-taking.
I love it! I thought I was the only one who could both appreciate the beauty of something both scientifically and ascetically :)
You guys made my day
Beautiful, the last part. Thank you!
Its me, from the future, we've seen it happen
I remember i was up in the very northern part of ireland and i saw the milky way for about 20 mins before it got too cloudy. It was an absolutely amazing thing to see.
i think the understanding of stuff gives it even more beauty!
i'd like each of this wonderful group of people to tell me something wonderful everybody should know, and then teach it to us in longer videos, or maybe a series of short ones, maths and all.
The Sunset question should have been a video on it's own. I was amazing to hear them. Thank you!
Very interesting video. Great job!
In my opinion, looking at the night sky and seeing the Milky Way , knowing that I'm basically looking back in time and thinking about the coincidences that had to happen in order for me to be able to do it makes it many times as amazing as it would otherwise have been.
Awesome to watch this now after the capture and measurement of said gravitational waves :)
Great point on the sunset bit. Science makes things even more amazing when you actually get an idea of what's going on.
@jnthnbush have ypu seen our black hole video about the Schwarzschild radius radius... the second part of that answers your question very well!
It's titled "Black Holes - Sixty Symbols"
I too enjoy the beauty of something like a sunset AND enjoy thinking about why it happens and how it happens. The understandings make it all the more amazing. Or at very least, fascinating.
Very cool video.
As an aside, I've watched tons of the Sixty Symbols videos, but I haven't noticed any biographies on the people being interviewed. Any chance we'd get a video where you ask each of your scientists a few rapid-fire questions so we get to know a tiny bit about them? Say:
1) Name
2) Educational Background or list of degrees
3) Primary field of research
4) Current project (if not secret)
5) Favorite hobby or pass-time
6) Favorite movie, or book, or music
I'd love such a video!
Watching this in 2017, amazing.
These videos keep me stimulated and keep me enjoying physics, even after an a level lesson with miss Hopkinson :p
i just love these videos. Plus I have to say, you make it very easy to understand, not just by explaining but by your speech, too. Though english ist not my native Language, I can still understand everything! :)
Learing how all that beautiful things work just blows my mind over and over again.
It is bloody amazing.
We got one by the mail in our university as well, and kept it preciously both as a warning and an endless source of laugh
Can't... stop... watching... sixty... symbols. IT'S SO GOOD!
@bozy99
It's rare for matter to be ejected from a black hole. But they were saying that if the holes are spinning fast enough, they can bounce off one another like two bey-blades.
A: A black hole contains the mass of the core of the star that formed it. Plus whatever other matter it happens to consume.
B: Most likely the holes would merge to form a bigger hole.
It's amazing to take the time to watch videos before important milestones
@salerio61 learned about it in a college class called, Physics of Light in Art and Nature. I always loved rainbows and I thoroughly enjoyed the session about Meteorology.
need to do an update on this
@MonMonsieurBleu That's Professor Ed Copeland...
Pictures and names of all our scientists can be found on the sixtysymbols website.
this made my day better :D
Thank you!
"20-30 years"
Oh, man, what a blast from the past. Just like that black hole collision, amirite
I like how they were on topic for a moment, and then, realizing that they had no idea what the answer was, switched topics after a couple of quick answers.
these videos are perfectly made
Fantastic!!
I enjoyed reading it. Very creative thought on your part, usually I read comments with peoples theories and they make almost no sense. Although yours wasn't completely right, it was but very thought provoking.
2:34 well that's so me there. not only in sunset but in many circumstances
Simultaneously appreciating and understanding a sunset is the same as appreciating and understanding the mathematics and properties behind classical architecture. You can see the Parthenon, the Coliseum, Notre Dame cathedral, your local courthouse, and innately sense the beauty and elegance and cohesiveness of their structures. Studying classical architecture and understanding the math and ratios and functionality of all the different components does not take away at all from the appreciation. If anything it enhances it because even knowing how something works and that it works, it does necessarily provide any insight into WHY it works and WHY it should be so amazing and appealing to us.
These are great
Really Happy to see "The Atlas of Creation" in the library behind the professor :-)
I love how fast science progresses! He predicted observation within 20-30 years but it was in fact only 6 years! Amazing.
6:20 loved that part
knowing how it works just makes it more beautiful.
yes i know he meant heavier but i hadn't thought about the fact that this would cause it to have a bigger event horizon. a very good point.
@BlindSoothsayer they have them on sale at k-mart
Damn! I Loooove that explanation!
Very nice. I like sunsets as well. I also think it adds to the beauty of the moon the fact that I can imaging standing on it, I can gauge the distances, understand the mechanics.
I'd say that of course there is a way in which knowledge can dim our appreciation - when we analyse things instead of experiencing them. But if you know a bit about science you no longer analyse the moon or the sunset. You revel in it because you understand it - it comes into better focus.
Who would have thought that the day would come so much sooner than the 20-30 years!
i think what somebody would be saying with the beauty issue is that knowing how some phenomena is produced takes away the mystery of it, and i guess in some sense that's true (at least for me). but i can still appreciate how a sunset looks... and i mean i think we should appreciate that we know some stuff about the universe. i think the fun of having mystery in your sunsets would quickly diminish if everything else around you, plants, animals, trees, rocks, planets, stars, light, etc, was also surrounded in a confusing, omnipresent veil of ignorance.
is there anything better than passionate people talking about beauty?
0:26 I was like "what??"
saw the published date... calmed down
@XVmaemoVX thanks!!!
Watching in 2016. The observations were made
@sixtysymbols im very interested in physics and I love your videos my dad is an inventor down in the states and right now im taking physics in school im just wondering how you guys got to the posistion you are in now and if you can suggest what i should take in college or university thanks
they actually observed something like this sometime this past year. 2 galaxies collided and instead of merging, one of the supermassive black holes at the center got launched out.
@unicyclepeon Brady's site on SixtySymbols' channel links to a page talking about the different scientists, and there are also "meet the scientist" videos that ask a lot of the same questions you do, though maybe an even more personal set of videos about them would be interesting and help appreciate them and their knowledge even more..
@sixtysymbols brady you are so awesome.
I don't understand how anyone could possible dislike these videos.
What a lovely ending to a video about one of the most destructive forces known to the only known intelligent existence in existence. You, good fellows at Nottingham University, have earned yourself a subscription
Think of in terms of a gear head out in his driveway working under the hood. He fairly well understands the basic mechanics of the machine , possibly its history , maybe even who designed it , ect. To this individual , their car is a magnificent piece art and beauty . to the onlooker , sure it's a gorgeous automobile , but all the knowledge the owner has , has made this car that much more beautiful.
"I've heard of some simulations which are modeling galaxies colliding", That made me chuckle... I'm now imagining some kind of back alley rouge physics.
@JeanKM1 I'll have to check that out. =)
@jnthnbush They are practically everywhere, possibly even in our uppermost atmosphere layers (only small, short-lived ones, tough). Actually, they're pretty common stuff in the universe.
this was posted on my birthday!!! :)
Thanks for the answer. But if a black hole attracts light so it cannot come back or if a black hole produces light that means that force 'catches' light, like a magnet, it slows it down I assume, so the c will still be the fastest speed in universe.
The slow I was talking earlier it's different from how light slows in different mediums (glass, water, air, etc).
If it is all about high gravitation, it's fine.
I wonder how light and everything acts in a black hole, it would be nice to find out.
yeah, I've seen that video before, great stuff! So, to recap, if you were able to heat up a steel pan to beyond plank temperature, you might get a black hole. Do you know if there's any situation in which something like this could happen naturally?
It was said in the video that if two spinning black holes collide one of them might fly off, what kind of speed could we expect?
where can i study particle physics (not formally) on the internet? im only 17, but i find it so fascinating
someone else pointed that out and i conceded that it was a good point.
@Ormaaj They have this very extreme gravity, which makes it less likely to form stable orbits.
@Ormaaj The cross section is increasing with the mass and the diameter of the objects. Galactic black holes are very massive and very big (compared to stars). And even if they miss at the first time, they emit gravitational waves and lose energy -> they come closer together.
'Friction' (impact of objects) from flying through the other galaxy helps, too.
OJ_287 is a nice example for this process.
1:10
Atlas Of Creation by Harun Yahya on the bookshelf oh my goodness.
I see beauty of the universe in a chicken sitting on the grass, its eyes closed, under the moonlight.
When you know how it works, you not only are amazed by the beauty, you also are awed by the meticulous design of the universe.
Wish I could go back in time and tell these guys what we know now. They'd be gobsmacked
Understanding a bit of the process that causes these naturally occurring phenomenon increases the enjoyment for me. Yes it's beautiful, but so is the process in which it's made possible.
You get a new universe!
It would depend on where you consider a black hole to begin. Does a black hole start upon reaching its event horizon or upon reaching its singularity. Or somewhere in-between.
Having been a fortunate recipient of an angle on one of those green flashes, I can state that the cost and effort for my pilot's license was well worth it.
And a point to ponder: because the musician knows how music is made, is the beauty of the music diminished? My Majick 8 ball says "Sources say 'no'."
