- On this episode of StarTalk Radio, we bring you the classic StarTalk formula that you’ve come to know and love. Neil deGrasse Tyson and comic co-host Chuck Nice answer fan-submitted Cosmic Queries on the mysteries of the universe, specifically, black holes and dark energy.
We start with a simple question: are we sure there’s a black hole at the center of the galaxy? Neil teaches us the methods we use to measure black holes. He also reminds us of the Copernican principle. You’ll learn why the more massive the galaxy, the more massive the black hole at its center. Neil and Chuck reminisce on the movie Marooned. Discover more about electron degeneracy, neutron stars, and pulsars.
You’ll hear if it’s possible for a black hole to re-ignite into a star once it loses enough mass through Hawking radiation. Chuck has an idea for a science fiction film about a killer black hole until Neil squashes it with some Star Trek trivia. We explore whether a black hole can warp spacetime around it. You’ll learn what happens to the gravitational well of a star if the star comes across a black hole. And, of course, it wouldn’t be a show about black holes if we didn’t talk about the movie Interstellar.
We ponder if “Planet 9” could be a black hole. If the Earth turned into a black hole would it still orbit the sun? The answer may surprise you. We investigate what might be at the center of a supercluster. Then, we dive into dark energy. Neil explains why dark energy is still mysterious. You’ll also learn more about the Albedo effect and the Doppler shift. All that, plus, you’ll find out if dark energy has an impact on your everyday life.

"Neil DeBlack Google" - Chuck 2020
Man, I was having dinner when I heard that 😂😂😂💥
Hahaha! If Neil DeBlack Google doesn't keep our info, I'm switching to him!
Should be Neil deBlackHole Google, haha.

@9:12
Chuck Nice is the best co-host. Period.
Watched the whole Episode! Loved it and this show is always, Always! So interesting. I love you guys, you help me get through my day just listening to you ❤
Archmage_ged he is great. but definitely go back to 2009 when he first started Star Talk. Lynne Koplitz was also a great co host. a little much at times, but still did a great job.
Maybe not the best - but he's nice for sure.
he's easily manipulated by media

I really can't overstate how much I envy this man. I realize a lot of his time is taken up with appearances and other social obligations, but having the mathematics foundation he has and the fundamental understanding of things that comes with is literally the greatest thing I could wish for. I went into the service because (unknown at the time/am now medicated & self-aware) I had ADHD, and knew I'd never be able to hold my focus through college. While in the service, I spent 10 yrs as a computer programmer and 7 more as the equivalent of an industrial hygienist... I've been an ionizing radiation safety officer (which required rudimentary training in that area to understand & calculate everything), evaluated multiple non-ionizing radiation sources (calculating and later measuring overlapping sources for occupational safety lines), and working with air/soil/water sampling and calculating my results was honestly both my greatest strength and love (next to my wife & kids). Now I'm a "retired" stay-at-home dad, and very rarely get to challenge my math knowledge. I'm happy with myself, but I can honestly say, this man's life is more than I'd ever be able to reasonably dream for myself. Mr. Tyson, I salute and congratulate you for both your accomplishments and the understanding you share with the world. Thank you.
Problem: "We want more questions" and "we want longer answers"
Solution: longer show! Can't get enough of watching NDT and Chuck
They need more money for that. I don't remember how much an hour long show costs to do but, it was in the 10's of thousands. I would love 2 hour Galactic Gumbo/Cosmic Queries but, Neil probably doesn't have the time or funds.
@@paulvamos7319 WHAT??? Thousands of dollars for 2 hour show? Why???
he found out he was so wrong that he didn't answer@@aviral1230
We want more questions AND long answers 😄
Perhaps if they film while moving near the speed of light...
Light! Hello Light? Could you please PASS the jelly
We just want MORE VIDEO FFS
Dear Niel, never stop talking and film it all please.
Neil the Black Google has all the answers! Lol 🤣
Plot twist: Chuck low key has had a bachelors in physics this whole time.
Shad for real tho?
@@tuluksvui747 no
Plot Twist: Chuck is NDT.
Is he still living with the bachelor? Or did they break up?
I would laugh for an eternity if he suddenly came up with a discovery that lead to a Nobel Prize just to one up Neil spontaneously.
Mr.Tyson and Mr. Nice are a perfect combination. You play off each other's energy in a way that makes me not want to stop watching and I'm left looking forward to the next episode.
Same here
I could listen to those two forever, lol. They are so funny and entertaining with science thrown in the mix.
Love these. The right amount of science and lightheartedness.
Gotta love Chuck.
I love when Neil gets so excited about something that he just starts hitting Chuck.
Professor Sypher wiredo
Lol me too
...I love their chemistry - they have soo much fun. 🤣🤣🤣
Chuck really scarfed down that cheeseburger man!
He is a bully in words
Love the chemistry this two have.
I see what you did there.
Keep the long answers AND add more questions, you could make the episodes a lot longer. The Joe Rogan Experience is evidence that people want to listen to long form discussions like that. 3 hour cosmic queries episodes would be wonderful!
someone : asks a question
Neil : well, there is a movie...
Really?
I think he gives movies as examples to visualize what he is trying to say.
@@christophergatchel4072 couldn't had said it better myself lol
Neil has seen every movie with anything remotely science related
Neil "wait wait wait" DeGrasse Tyson
Man these Podcasts are very interesting. I’m re-thinking my existence.
Welcome to StarTalk.
John Yepthomi I know
@@PremierCCGuyMMXVI I'm just greeting you in.
You seem to be new here
NOMASAN I’m not Im just saying. I watch Tyson a lot
These two individuals are a gift to our world! Amazing podcast show
Found this channel from CinemaSins and so glad I did. Dr. Tyson is the perfect way to start my day. You are so very awesome Dr. Tyson.
14:50 the gold foil experiment was performed by Rutherford :)
Yup, it was Rutherford scattering experiment.
This encourages me to believe that Neil is gatekeeper and cover-up for USA & NASA!!!
Jay Buch Stop dude. Just stop
I'm studying for a chem exam and I thought I was crazy for a second
Nah! Neil’s just getting older. J.J’s experiment included Rutherford’s so I would say mix up do to aging (which I’m a pro at.)
I have to say, without Chuck these podcasts would be far lest interesting and no other co-host came close to his (comedic) value. Even tho I can listen to Neil talk for hours, the chemistry they have raises the show to a whole new level.
"I have to say, without Chuck these podcasts would be far lest interesting "
So black holes and dark matter isn't interesting enough, you need to have a college roomate 'laugh it up'.
Maybe this field of science isn't for you?
His job may seem like it's just to joke around and bring humor, but Chuck always manages to circle back around to the question or topic and steer things in the right direction... EVENTUALLY lol for real though, he does a great job.
Oh, and Neil DeGrasse Tyson? He's my hero. It almost goes without saying but I couldn't just praise Chuck without throwing respect to the maestro.
Neil's laugh is fantastic!!! This is now one of my top 5 episodes!!
Neil went in so DEEP on this topic of Black Holes he popped through into another Universe. Signing out.🚀👍
I wish to be an astrophysicist or an aerospace engineer or BOTH
Somebresome Thank You I will 😁
We're rooting for you, Shiloh!
Did you do it yet?
learn to love physics....EVERYTHING astronomers deal with , is physics....
@@lonelyrabbit7224 • wow... #TrollMuch?
Earnest Rutherford discovered that the atom was mostly empty space. J.J Thompson discovered the electron. Love the show. Currently combing through every episode and I'm positively enlightened.
I love Neil and Chuck..What a fun duo to watch and listen to 😁❤️
What I really like about Neil is he explains it in a way even I can understand lol enjoying this show so much, Thank you 🤯
He and Carl Sagan both have that ability to relay the information in simple terms, not just so WE understand it, but so THEY can too! It's a great gift, for sure!
Its coz science is so fascinating 😍
i was hoping this was a new episode 😩😩😩 never the less this is my favorite topic
Probably my favorite episode :3
Breon, where did you see this? It's new to me.
I love this channel so much. You two entertain my wondering mind all everyday while I'm at work and while I'm watching TV at home. I honestly don't know what I'd do without you two. Probably keep wondering.😂
Man... saying I love this show and you guys. Is an understatement
someone gift NDGT immortality...i will continue to listen to these podcasts in 2100!
Have you been gifted immortality as well?
@@smoshuajoshua maybe
oh yes pleaseeee !
Neil and Chuck episodes are the best. No guests (except for a few) can top that
Neil: did we answer that.
Chock: yes
Neil: oh by the way.
Lol every time!
Who r u?
@@zizo4921 nobody
Neil & Chuck, you guys rule!!!! THANK YOU FOR THE INFO & ENTERTAINMENT!!!!!! X ... INFINITY!!!!!!!!!!
Ive been dying so hard over Neil DeBlack Google took me like 10 minutes to stop laughing to try to explain to my girl why this is so funny 😂😂😂
Neil and Chuck are awesome!!
Neil reminds me of my Dad in so many ways. I could listen to Neil all day! Chuck is a perfect partner!! 😂. "How does the head of the snake eat itself?"
Neil and Chuck, I can't describe it, but the chemistry is just great. Keep at it, guys!
As a guy who drives a Chevy Equinox, I want the show with different stuff with cosmological names. Love you guys.
43:39 I thought that was the moment we were about to lose Neil. Great! We broke him! We definitely can't just go get another Neil!
I lost it at that part 😂
that was funny
I think he had an algorithmic break down! XD
I’m learning so much. I wish I had paid more attention in school. Lol.
Me too🙄Now it's too late😒
if i can see 1% of Neil and Chuck everyday, i’m happy! :D
🌎🤟LOVE StarTalk🤟💯
Man, this has been a great week for Startalk! Must have wrapped yup with Cosmos, which has also been awesome!
Yes!!
Love these guys
I want to see neil and steve harvey doing things like this podcast talking bout planets, black hole, universe etc. That would be amazing and hilarious at the same time! 😂😂
“I know a lot of people ask what Omaha means. Omaha is a run play, but it could be a pass play or a play-action pass depending on a couple things: when, which way we’re going, the quarter and the jerseys that we’re wearing. So it varies, really, play to play. So, that’s - there’s your answer to that one.”

Jermaine Murray nvm my bad😂

Just remember, us backroaders get to see our beautiful stars clearer then most people ever get a chance to. But yet we're the odd ones....
When we take road trips we avoid main roads at all cost just to see the sights. Keep rolling!
Heck, cosmologically speaking, we're all backroaders. Pretty long drive to get to the nearest supercluster from here.
I love when Chuck asks a question that's been on my mind. Thanks Chuck! ^^
I love these guys and I love this episode. I went to a “talk” that Neil presented at a theater here in Ohio about 6 months ago. Was a great experience. These 2 together could take what they’re doing on the road and I’d definitely pay to see them. Thanks guys
Educational AND hillarious! Want to see more cosmic queries with Neil and Chuck!
I can’t believe how much this made me laugh bearing in mind the title I clicked on. 2 real entertainers.
That's why I am addicted...they make science fun!
Best show on CZcams
I really love the chemistry , Love listening/watching them while working
Thank you Neil! I really like the omission of the lightning round this episode.
Perhaps revisit the idea from time to time? Sometimes a lengthy answer helps gain a bit better of an understanding.
And often, many of the questions during a lightning round are deserving of a more thorough answer.
I want the show about names of things stolen from astrophysics
I rather use "inspired by".
Well for starters along with the Astro van, there is the Saturn, the Rover, the Aerostat, the Sun (I think) and more.
“Neil D’Black Google” 😂😂😂👍🏽🤘🏽💪🏽❤️ LOVE YOU GUYS!!!!
Honestly I love the long answers. I came here to listen to a smart guy. Tell me smart things. And the more in depth you go the more passion you put into it. So I'm always in for long answers. Because it's a journey.
48:43. Another great meme.
Fr, I was listening to this and I was like,
“Ain’t no way that’s what I think it was”
@@lkv0315 hahaha. I feel ya.
I listened to this on spotify too but it was so interesting i had to watch it now as well
I imagine the reason for destroying an entire planet by turning it into a black hole is either a show of power to intimidate, or an act of emotion simply meant to incite terror or some other strong reaction without any real foresight
Love you guys!! Even two years later you make me laugh out loud while I'm learning really cool stuff!! Thank you both and all your guests Jan11 lol is great. I wish I could afford to go to school and learn these things. It's too late now. I'm 62. But it was a life long love of mine and you give my uneducated brain bright lights of Knowledge and tons of food for thought.
I'm thinking of looking stuff up on black Google... maybe there won't be rabbit holes there... only black holes lol! Neal I have all your books except the ones in print. I suffer from migrating that take my sight so I rely on audible books. I'd love it if you can get your editor to produce you latest books on audible with YOU as narrator ! You read wonderfully and your shows podcasts etc., I have them all. I love the chemistry between you two!! I have a question but I won't ask since you're probably not reading these anymore. I just really wanted to thank you for doing this.

4:00 regarding the analogy with the eye of a hurricane, i have a theory that the centers of black holes must also be the most quiet and empty place in the cosmos.. Because hear me out here. I know we calculate gravity AS IF 100% of the mass was compressed into an infantessimal point at the exact middle, but thats not the PHYSICAL structure of matter. For example, we calculate the gravity of orbits around Earth, AS IF earth's gravity ALL came from a central point in the middle, but of course it varies depending on densities in the rock, mantle and so forth. But for orbits, thats fine enough to produce accurate results.
Now, hear me out. If black holes distort time so much that it essentially "freezes" beyond the event horizon, or even if its only at 0.00000000001% temporal speed, wouldnt this mean that nothing that ever fell into a black hole, no matter how many billions of years it has existed, would ever actually REACH the center? Because in order for ANYTHING to reach the center of the black hole, it would need an INFINITE time, since time slows down the further you go, right?
So wouldnt this mean that black holes must be like an egg, with a super-hard SHELL of matter, all the matter that ever falls into the black hole during its entire lifetime gets trapped in a density-gradient of a shell, because NONE of it has had enough TIME to reach deeper, right?
A density-gradient of time, where the deeper you go, the more sparse matter is packed, because NEW matter that falls in, will fall inward QUICKER than the OLD matter can fall, due to time dilation. So it would create a sort of tidal wave barrier, where new matter keeps washing into the old slower "stuck in time" matter. Time would create a "wall" of compressed matter, beyond which nothing can pass. Not due to density, but due to time.
At the exact center of the black hole, the singularity, must be a perfect VOID of absolutely nothing, because nothing would have time to reach the center, since time isnt progressing there (or, at such slow speeds that it'd take the lifetime of the universe to just spawn a random subatomic particle).
I've always wondered about this. Because if time slows down to an essential stop, as you enter the event horizon, how could any matter actually "reach" the center? From OUR outside perspective, of course is what im talking about. It would be the same for a human if you could survive, and if you could "see out", you'd see the entire universe age and dilute into darkness by trillions of years, before you even got halfway to the center of the black hole.
So isnt it the case that black holes then, logically, MUST be "eggshells" of ultra-dense matter surrounding a perfect empty void, a void of both time and the absence of even subatomic particles?
Thus you might say, black holes are BOTH the most dense objects in the universe, AND the most perfect voids in the universe.
Sorry but time is relative. What it means is that to observers far far away from the black hole, it seems like matters falling into a black hole freeze, not that it actually does. The reverse is what happen to someone close to a black hole, he would see the space far far away from him to speed up faster and faster. But in local space, far far away and close to black hole, time still ticks the same. Time does not change, the perception of it changes due to distance and gravity.
Also, in Interstellar movie, the plot during the water world where some 20 yrs passed between the people on the surface and the people on the ship is a little (or actually way way) off. To have such a discrepancy means that the ship is further away from the planet than that to happen, which means that the shuttle would never have enough fuel and such a short time to go between the planet and the ship. If the ship was just orbiting the planet, then its local time is the same as the planet.
@Baleur you are absolutely *WRONG*
We’re inside a black hole I think, Richard Lee has just confirmed it for me. Lol
Glad your at least asking questions, more questions the better.
My favorite academic ever! 🚀
chuck asks fantastic questions. Thank you both for the great program.
ok ive been really stressed and feel like crying so much lately but listening to u helps me a lot thank u so much
The look Neil gave Chuck when he was inquiring about Planet 9. I think he knows something
But I'm repellant to lightning
Nah conspiracy theory guy, he was just disappointed.
Plain old disappointment.
@@z.niamut4045 😅😅😅 I ain’t no conspiracy theorist just a curious individual
29:20 and this is why I respect Neil, it really bothers him that Chuck didn't knew the name of such an underrated classic of science 🔭🤓🧪 fiction called.... Inter-stellah or something😂👌
These shows are so uplifting. Thank you.
Whoever came up with this show is genius, funny facts are perfect. And so phonically smooth. Great laughs & chats, must be great being Neil & Chuck's mates at the pub after the show.!
10 stars every time, even from pre pandemic.!
How cool is that you can do science with a particle cannon. That sounds like something Mr. Fantastic or Tony Stark would build to defeat a supervillain.
I want to become an astrophysicist. I love space and love to prove myself.
Finger crossed❤️
Love it. Chuck and Neil are really great. would lov eto see them at comic con.
Stopping by again for the clinic to be put on!!!!! Thank you both 🙏❤️❤️🙏
As well as the Startalk Enterprise Team making it all happen!!!!
My children love when they get to flay their Christmas presents
quick question though: how can neutron stars have magnetic fields when there are no charged prticules in their cores?
Im no scientist as im still in middle school, but i think its becase it spins fast enough
Sorry for the late reply. I think I remember neutron stars having a thin solid crust and a layer of kinda like super fluid right beneath. The friction between the two layers is what produces the magnetic field. I don't know, i didn't even check, just wanted to give the most sincere answer possible. If I'm wrong forgive me 😁
I love these guys they are so funny :) having people make intelligent jokes while discusing interesting yet complicated matters its metaphorical gold. Thank you.
could watch this an infinite amount of times
I love how ndgt not only has to think of all the answers but also has to remind chuck when the breaks are.. get it together chuck!
“You need to black Google”😂🤣
I seen chuck perform live he is hilarious.
I love the long answers, makes me really understand the subject
I love long answers. Thank you for your time.
Always wanted to know more about dark energy

I went to grade school in Hyde Park N.Y. (Violet Avenue Elementary circa ‘72-‘76) The education system in that part of country was phenomenal in the years I attended. The field trip which;to this day, is indelibly etched in my mind, is to the Hayden Planetarium in ‘72. It was Uranus (long A) then, it’s Uranus today and it will always be Uranus. Thanks for continuing the great reputation and continued excellence as the Planetarium’s Director. Love your show… and see you in November up in Greensboro N.C.
Chuck looking into the camera, sometimes for help, sometimes defensively, sometimes because he's lost, it just cracks me up
Hey, Neil! Didn't you confuse J.J. Thompson with Rutherford when talking about that gold plate etc?
Right? I thought Thompson was the plum pudding model.
@@matthewbay1978
Thompson was 'the electron discovery guy'. He opened the door to subatomic world, which is 100% fake news anyway. And I don't even remember who of them was plum pudding model guy... Maybe it was Thompson.
you're right. thx for correction😃
@@ladymiss9466
You are welcome! It was funny to see Dr Tyson making a mistake. Have never seen one before from him. Maybe he can do me a favour for correcting it. Maybe he can read my book and say what he thinks about the pattern of Magnetic field I am suggesting there to replace the existing one. And, if you are interested, I could send to you a full description about the true pattern of Magnetic field as pdf. In case you are interested, my email is immigrantgeorge123@gmail.com
Trust me, it is interesting read. Just imagine that I am right and the pattern of Magnetic field looks completely different from what our textbooks show... Worth a shot in terms of having a look at it, don't you think?
@@ladymiss9466
And the book is this one.www.amazon.co.uk/dp/B086MN48GY/ref=cm_sw_r_wa_apa_i_5QoIEbQ4FMMZ3
You can have a peek inside if you click on 'look inside' when have chosen the book on amazon. But it only works on computer.
The gold foil experiment was done by Rutherford. JJ Thomson used a cathode ray tube.
Yeah I was wondering the same thing.
I think the way ya’ll do the show is just perfect!! 😃😃
I just love listening to you guys talk

Is Chuck Nice the character “Waldo” from Family Matters?
Uani P lol nah
He isnt and im pretty sure that guy died.
😂 😂Chuck does kinda resemble Waldo Geraldo Faldo at a blurred glance. Love them both! ✌🏾🥳
What an episode as usual guys ❤️
Regarding Peyton Manning..... You will notice that when he calls "Omaha", it's because either the defense has shifted into a different position (attack mode) and he has to then call an "audible" (AKA: change in plan). Or he may call "Omaha", if he see's a weakness in how the defense is lined up, so he will call an "audible" in order to take advantage of what he see's as a flaw in the defense. Each team and each quarterback have their own audible. I pretty sure if you go to CZcams and look up the keywords: Football, Quarterback, Audible... they'll probably explain the whole process to you.....
He uses Omaha because it is an easy word to say in a loud situation.
To answer the Peyton Manning 'Omaha' question it means hes calling an audible translating to opposite.. instead of left, run right and etc.
These two together are great listening. They should go on tour together.
Love Neil, Chuck is really special too.
Hello, Neil.
"Hello, Neil." Next you're gonna say "If you turn around you will find an envelope with a request to join us, it is not a request."
but who requested this? oh but it was they you'd never suspect!
because nobody suspect's the Spanish Inquisition!

Thanks Chuck, for making me laugh out load, a very rare occurrence of late.
