Primordial Black Holes - Sixty Symbols

[@kapa1611]

is this guy always so calm? its very relaxing to listen to his voice xD

[@kapa1611]

i have to rewatch it to pay more attention to the content... xD lol

[@bigbenhebdomadarius6252]

He's usually like this, but if you want to see him in an excited state, watch the series of videos about his visit to the LHC. He was practically weeping with joy.

[@kapa1611]

xD it makes sense then ;)

[@jedaaa]

;)

[@phdnk]

his voice creeps me out - because I consider it inappropriate: as if he would be hitting on me

[@PlanetAstronox]

I love how on point Brady is with his questions. They really contribute to how interesting the video is.

[@gabrielx95]

Life savers

[@daveangels]

ah finally a new Ed Copeland video, time just flew by watching this, my favorite professor of this channel.👍, we need more and longer videos like this

[@salottin]

YES. It's the ones I learn a alot but leave dumber, with more questions

[@Twitchi]

Ed has been my favorite for a long time now.. Especially in this longer format, It is a shame they are so few and far between

[@kennywebb5368]

Agreed! Especially love moments like 13:36

[@victos-vertex]

Couldn't agree more, he is my absolute favorite aswell, damn even my four year old daughter likes him. He just seems to be such a nice person and I love how he is full of passion and actually enjoys what he is doing.

[@m4tt7610]

[@freeboson]

I'm a theoretical physicist working on this exact problem, and this is really an excellent video explaining so much of the current state of research here. Great job to all involved!

[@TheGargalon]

any progress in the 2 years since your comment?

[@user-me7hx8zf9y]

I am also interested

[@captainhd9741]

Keep us updated

[@captainhd9741]

If you’re still alive that is

[@nosuchthing8]

Could dark matter be mini black holes?

[@shaunhutchinson4707]

What impresses me is how Brady can understand the context of all these topics well enough to be able to ask further questions in the videos, especially when he doesn't have a Maths, Physics or Engineering degree.

[@jacobshirley3457]

He probably reads up on some of this stuff in his free time, since he obviously enjoys learning these topics.

[@mastershooter64]

Even if he doesnt have a degree in stem im pretty sure he graduated high school im pretty sure any high school student would know about quantum gravity or hawking radiation or schwarzchild radius maybe some would even write papers about it or come up with equations

[@jacobshirley3457]

In my high school, we never learned about those subjects in science, actually.

[@rick777888]

fairly rudimentary questions...

[@CanOzmaden]

I am a simple man. I see Prof. Copeland in the thumbnail, I press like.

[@sciverzero8197]

He is a simple man. He simplified.

[@kashmirha]

Mee too :) Sometimes they say something in the first few seconds, and I HAVE TO exit from full screen to give a propper like :D

[@jackmcneil3214]

Props to this channel for still making top-notch educational videos. So many "smart" youtubers have gone the way of clickbait

[@Bunzotennis]

Favorite professor! Props to Brady for the critical questions

[@Aceshifter]

6:18 worst jumpscare by sixty symbols to date.

[@reblogo]

This isn't numberphile :p

[@Aceshifter]

true, thanks

[@JustOneAsbesto]

The clap? Are you serious?

[@maxzhao]

True

[@AuroraNora3]

It's so soothing to listen to his voice then *CLAP*

[@raccoonlad]

i love the art style of these videos!

[@sixtysymbols]

+Jonah it was by Pete McPartlan

[@MishaMPLS]

Dr. Copeland's expression when you asked about black hole accretion and its impact on evaporation was equally one of surprise and the pride of a teacher whose pupil was finally understanding enough to think about the problem and meet him rather than just receive lecture.

[@jaimeduncan6167]

He is one of the best in the sense that he is clear in what we know , what we don’t know and what we may not know.

[@Pow3llMorgan]

I let out an audible "Yes!" when I saw a Sixty Symbols upload with Prof. Copeland's face on it.

[@Ana_crusis]

did you? That's wonderful. and now we all know that. We don't know you or where you are in the world or anything at all about you but we *do* know you, a person on the planet's surface somewhere, let out an audible "yes!"

[@Triantalex]

cringe..

[@gautampassi3863]

Brady and the whole team is doing a great job at bringing us this spectacularly brilliant content.

[@vebbto]

I love this. Not only are these videos interesting, I get a nostalgic feeling to when I watched these videos in the pivoting year 2009 in terms of my interest in physics and mathematics. Sixty symbols was not the initial spark that got me interested in physics and mathematics, but it most certainly made a breeding ground for my interest. I want to say a big thank you to Brady and the physicists at Nottingham University. You're part of why I just got accepted to do a masters degree in theoretical physics!

[@bobburger2297]

Ed is my favorite professor in the series! It he is so patient with everything. Although I have to admit my favorite videos are when he gets his feathers ruffled. He doesn't even get upset he just gets slightly frustrated and stands his ground. Either way it's always a joy watching his videos.

[@samirhussain458]

I'm a physics student, and every time a new video is released on this channel, my mind is blown! THANKS!!

[@normalasylum]

I love a wandering deep-dive conversation like this. It reveals just how complicated the subject is, and how many unanswered questions we still have. Thank you!

[@Si-Al-Ti]

i really like your talks with Ed, super interesting! And the art style and color grading of this clip is really nice as well :)

[@arturmizuno]

you could make a series of all states of matter (from solid, to plasma, bose einstein condensate, etc..)

[@Minecraftster148790]

Artur Mizuno that would be interesting. At school we just get "there are three states of matter" and then later on "we lied there's more, moving on". And then we don't get any more about them

[@danlorett2184]

I did a double take at the "10^-5 grams is Planck Mass" thing. All the other Planck units I know are so much smaller that I had to look up if that was right - it just seemed weird that Planck Mass is 10 micrograms while Planck Length is something like 1.6x10^-35 meters. But it was right! I guess Planck mass is the only Planck unit that people can actually visualize the scale off - google says it's the mass of a flea egg or whereabouts.

[@KohuGaly]

yes, it is also the mass of an object that has planck size (very small) and planck temperature (very big), so it's not that surprising the unit is somewhere in between.

[@ceruchi2084]

I was surprised too!

[@tomhill7249]

Screw Krauss, Tyson, Guth and the rest. I've watched almost ALL the physics videos I can find on KZbin and you my friend explain at the best level of detail with the most concise explanations I've seen yet. I haven't heard anything really new and interesting in a while and checking back to Sixty Symbols has definitely left me fulfilled. Keep at it mate.

[@NICHOLSON7777]

Prof Copeland could tell the world was ending and I'd approach it with a 'can do' attitude. You can't help but like the man.

[@nk11931]

I didn't understand anything, but this man seemed enthusiastic and confident enough, so I believe what he's saying is true. 8/8 would watch again.

[@sherlockholmeslives.1605]

I don't understand these videos I just like being lost by how intelligent these people are.

[@Sasha-fm6ou]

I like physics, don't get me wrong... but I cannot focus on the content with such a calm and soothing voice in the background. This is Through the Wormhole with Morgan Freeman all over again.

[@racketti]

I've watched this for two seconds now and I'm convinced that I'm going to enjoy this video because of professor Copeland and black holes.

[@johnnybro13]

ed Copeland is so calm yet excited it is beautiful

[@leobarlach]

this one was one of the most interesting explanation of how theoretical physics work. we model this, then we should see this, but if we see that than the model should answer that.

[@sivarttravis6802]

We need more Ed! I Love these videos, the way he simplifies these complex ideas so anyone could understand is fantastic. Could listen to him for hours! Great back and forth as expected from Sixty Symbols.

[@PinkChucky15]

I will never tire of learning about Black Holes.

[@911gpd]

So exciting to see there's a new Sixty Symbol video :D

[@klausvonshnytke]

I love this channel. Professor Copeland's and professor Merrifield's talks are amazing

[@Junebug89]

I love Ed Copeland. I hadn't watched in a little bit, this art style is new to me. I like it quite a bit too.

[@CJonestheSteam72]

Great that Ed had time to do this video, always interesting on subjects that are thought provoking and not necessarily easy to grasp.

[@sam08g16]

1:03 I always wondered, when there is something written on whiteboards behind the interviewed person, was it there before or did you write some random matrices just to fill it a bit?

[@trailblazer1615]

Ivan Mazepa there is determinants too

[@AuroraNora3]

Maybe it's from class

[@Sam_on_YouTube]

Ivan Mazepa That's linear algebra on the board behind him. Linear algebra is often used in quantum mechanics, though it is used in many other areas of physics too. I don't know enough to be sure why it's written there. But if he wanted to write sonething on the board to look impressive (which would be highly unlikely) that wouldn't be it.

[@leonetassinari6654]

I think it's from a linear algebra class. But I doubt it has anything to do with the topic of the video.

[@CraftyF0X]

Those looks like tensors to me, and they are used for all sort of things in physics.

[@Crazy_Diamond_75]

I love love looove listening to Ed Copeland talk about this stuff

[@althaz]

So many videos on youtube make you *feel* like you learned something, but an hour later you remember nothing about the subject. What I like about this channel in general and Ed's videos in particular is that they are the *opposite* of this. I feel like I have no idea about this subject...but I could explain to somebody else probably a lot more than they knew before.

[@MrMATTMAY25]

More Dr Copeland videos!!

[@headshiphero]

More Ed Copeland please - he's my favourite!

[@johnredberg]

I absolutely LOVED the Campbell's soup visual! Very clever, and great design style! (Everything else was great as well, of course, as usual ;) )

[@damianvila]

Great subject and animation. Loved this video. Best thing I've seen today on KZbin. 😊

[@lennutrajektoor]

Animation is stunning!

[@passthebutterrobot2600]

"The thing about a black hole - its main distinguishing feature - is it's black. And the thing about space, the colour of space, your basic space colour, is black. So how are you supposed to see them?" Holly, Red Dwarf

[@otakuribo]

Look at all these animations! 👍👍

[@audiocancer]

THIS IS THE UPLOAD I'VE BEEN WAITING FOR!!11one

[@alecdacyczyn]

So what happens when one of these mountain-mass blackholes wanders into a burning star? I imagine it would accrete mass at a fantastic rate as it falls/burrows through the star's outer layers and then settle at the core where it would rapidly devour the star from within. What would the emissions from that look like? And if the star was spinning then the angular momentum would have to be preserved as the mass becomes concentrated into the schwarzschild radius. It'd be one hellofa fast spinning top. And of course the jets of radiation and particles shooting out as this singularity consumes the doomed star would interact with the not-yet-adsorbed stellar material to create an upwelling of plasma at the polls. I wonder if it would have enough energy to escape the star's gravity or if it would fall back down like a fountain. Sounds like it'd be a fun supercomputer simulation.

[@theatheistpaladin]

Black holes like S5 0014+81 have to be Primordial black holes. A black hole feeding from the beginning of time. That is the best explanation to make sense of its sheer size.

[@darioinfini]

OK so trick question (I don't know the answer): If the universe exploded as a single point in space that contained everything the universe currently has in it, why was *that* not a black hole? Surely that much energy/mass in that small a space would be enough to create a black hole. Why didn't the universe just explode into an instant black hole?

[@sigert3463]

There was no space outside that point. So it wasn’t a black hole

[@carldowningphoto]

This subject needs a follow up. Fascinating!!!

[@salottin]

The editing is great!

[@mindwork1]

I love those videos, do it more often please

[@rafakukua2784]

I just wanted to say that it is a great channel. Keep up the good work and keep these interesting videos coming ;)

[@PINGPONGROCKSBRAH]

I love professor Copeland's lectures

[@busybillyb33]

2:44 That Campbell's quark soup pun...absolutely brilliant! lol

[@sergheiadrian]

I could watch professor Copeland explaining things all day.

[@andywright8803]

Pure joy. Excellent video, challenging material made digestible.

[@PTNLemay]

lol, Brady has his physics-hat on during these interviews. He's really smarter than his "caveman" persona lets on.

[@jacobshirley3457]

I feel most of the time, he's asking the question the "average viewer" would ask.

[@theporcupine9993]

He's An excellent journalist. !

[@all5gory]

I was looking forward to a new video with Prof. Copeland! And such an interesting topic. I always found black holes so fascinating. The animations are also great ^^ Thank you all for what you do, keep doing it please :)

[@mattrenegar476]

I

[@davekat]

Campbell's Quark Soup. Hands down the cleverest thing about this video. With all due apologies to Prof. Copeland.

[@BattleBunny1979]

12:25 science explained in 15 seconds!

[@mirkono]

best channel ever.keep it going brady!

[@lord_toad]

Nice visual upgrade :)

[@mr_awesome_y3k]

Love the art on this one.

[@sixtysymbols]

+Christopher Macrander thanks to Pete, who did it!!!

[@Flammewar]

Nice video. I just read a paper about Planet 9 and the possibilty of Planet 9 being a Primordial Black Hole. Such a interesting theory.

[@brilliantbrunch]

Great video, love the content, and how Ed explains things. Also, Brady killing it with the questions xD

[@ahmedal-shabi6032]

finally a long Ed video

[@JustinPerea]

I wish this came out sooner. I had to write a paper for my cosmology class and part of it was Primordial Black Holes. This would have helped get the ideas flowing -_-

[@jamesrockybullin5250]

I always find black holes and the early universe super scary. I jumped out of my skin at 6:19! I did not expect a jump scare from you Brady...

[@xIPatchy]

I turn up my volume so that I can hear Ed's soothing gentle voice, so 6:20 scared the shit out of me.

[@KebradesBois]

I could listen to Pr Copeland for hours...

[@PriyabrataMohapatraiitmadras]

That's Gaussian elimination method on the whiteboard.

[@GBart]

We don't necessarily have to wait for them to explode to see them. The wavelength of light they give off is changing according to a function unique to very small black holes. We just need really powerful radio telescopes

[@FHBStudio]

When he was talking about high energy photons I just thought "Imagine what we're all missing out on because we cannot measure them yet, or even in principle."

[@jeriatrick]

Could a black hole be split to form 2 or more black holes.

[@themaximus144]

I love this channel so much.

[@General12th]

I'd like to hear more about so-called "relic black holes", in which a stable black-hole-like remnant is left over. How many of these are there? How common are they? What is their cross section? How could they interact with matter? And so on.

[@elliottmcollins]

This was really fascinating.

[@andrewwatson189]

I am so jealous you get to hang out with these people haha

[@feynstein1004]

Me too. Most of my friends are cavemen compared to him. Wish I could hang out with cool people more often.

[@n1k0n_]

more sixty symbols videos Brady!!!!

[@fabbocake6807]

Those matrices on the whiteboard are giving me horrible flashbacks of further mathematics at school.

[@will2see]

2:52 - "They could have formed right at the plank era although you got to be very careful, we don't really understand the physics of quantum gravity." - I agree, but somehow you have no problem invoking a singularity at the center of a BH.

[@Jack__________]

Underrated! 💯 this was brilliant! 💯

[@michaelsheffield6852]

Nice to see Ed Copeland ... another great video! Thank you. Damn quantum gravity

[@pipertripp]

Great discussion. really enjoyed this one.

[@boe_zh]

Yo, professor. Just one hint from a native German speaker: there's no "child" in Schwarzschild. It's Schwarz-schild (black-shield). 🤘

[@xavierjudd968]

About that primordial soup, is there a gluon-free version? I stopped following trends when Planking was a thing, but according to Ed, this goes back just as far. ;)

[@genius27641]

Can two neutron stars collided and combine? What kind of forces are in play? Do they impact like solid objects or meld like two drops of water?

[@Maharani1991]

Beautiful video. The quark soup illustration is as hilarious as it is intuitive. :)

[@MrAntieMatter]

Love Copeland.

[@jamieliveshere]

Beautiful animations Brady

[@rykehuss3435]

Brady didnt do the animations

[@RT710.]

Oh man I seriously LOVE science

[@alfriedrich]

Great questions Brady

[@arasharfa]

i love these high information videos

[@arthurklause5251]

Thank you for this video !

[@SatishSetty]

The whiteboard behind him, it's elementary row reductions of matrixes. Did I mention that Ed's voice is .... ?

[@adnemuri7220]

so, question, the univers is expanding,and the univers is space, and space and time is part of the same thing, does time also expand?

[@GeschiedenisPO]

Brady should get a professorship for all of his contributions to education! Oh wait...

[@paulfrancis8836]

Professor Ed seems a really nice guy. He's as smart as any, but never brags, or gets uptight.
