Neil and Charles Discuss Their Dream Time Travel Destinations

Are black holes places or objects? Neil deGrasse Tyson and cohosts Chuck Nice and Gary O’Reilly answer grab-bag questions about distorting spacetime, Olbers’ Paradox, singularities, the shape of the universe, and more with astrophysicist Charles Liu.
Could you create a cloak of black holes to make time cease for you? Learn about configurations of black holes, time dilation, and Einstein’s relativity. Would it take you until the end of time to reach the singularity of a black hole? What would you see if you fell into a black hole? Are we all just prisoners of the present? Plus, Neil divulges how you can hear his voice at a Beyoncé concert.
Can you transfer information using quantum entanglement? We break down how subspace gets used in Star Trek, what it means for gravity to distort spacetime, and how gravity can be used to deflect asteroids. Discover Olbers’ Paradox: why isn’t the entire night sky bright with starlight?
If Neil and Charles could time travel, where would they go? Could The Big Bang be a white hole? We talk about creating a Dyson swarm, using aerogel to insulate a journey into inner Earth, and the shape of the universe. Is the universe really flat?

Who's excited that the band's back together again?

[@lbthingsstuffmore9513]

Meeeeee!❤😊😅

[@lbthingsstuffmore9513]

Btw, Tom Paris went warp 10+ and came back jacked up!😂❤

[@konigtonig]

Such a great comibnation of persons, each and every one. Love to watch and educate me through this medium.

[@LightDiodeNeal]

Best channel I've found, condensed physics fun, what's not to love! 🙂 Especially loving the grab-bag ones. But if time stops for objects falling into a black-hole, how do they merge? I'll ask one day when I've joined! 😀

[@justfasial01]

This episode was shorter than usual 😞 But I'm loving that you guys are doing episodes back in the office again 👍

[@coder001]

Charles Liu in person is always a must watch

[@UnderstandingCode]

singing panama!

[@Leftyotism]

Not gonna lie, Charles Liu is my most favorite guest!

[@kenshinpsn3234]

me 2!

[@ShaulMTN]

Love how Chuck has come a long way, it shows what impact Neil has had on education. It also says a lot about Chuck's comprehension as a "Comedian".

[@jaelo2314]

AND he's funny!

[@JP-xd6fm]

@@jaelo2314 It would not be the same without Chuck, is a great co-host. And very funny!

[@fxthe1st]

Morty 😎 from season 1 is not the same as season 7

[@traviscole5140]

He talks too much. I can listen to a fool anywhere. I watch the podcast to listen to scientists.

[@JJs_playground]

I thought the same thing. Chuck's understanding of concepts is impressive, especially considering he's got no education in these subjects.

[@humanform5354]

Always a treat when Charles Liu is a guest 😊

[@CarletonTorpin]

I click instantly whenever it's a longform video AND Charles Liu is a guest.

[@GerodW]

I love these 4 together. It needs to be a regular thing in my opinion.

[@vids2see4me]

"Oh, that's in the Bible"😂 Chuck, you are pure gold.

[@erikhendrickson59]

Chuck been watchin some RM Brown

[@jaquelinez2991]

Neil being throughly impressed with Chuck was so heart warming 🥹😩🤍

[@scotteagle3597]

THE question that go me into Astronomy back in 1982, was "Why isn't the whole sky white from starlight?" Today, I finally heard a simple and easy to understand answer. You can. It's the CMB, just stretched out to wavelengths we can't see. Thank you!

[@LSA30]

The Great Startalk Council has finally convened!🎉

[@HisameArtwork]

ikr, so awesome! loved it!

[@AV8R_Surge]

Best outro ever 😃. Glad you kept it in.

[@TheAmethyz]

that was much better outro than what the lady would have wanted.

[@AV8R_Surge]

@@TheAmethyz Maybe because of copyright infringement fears? I think as a parody, it may be considered transformative and possibly falls under fair use. But I'm no expert. I'm sure they did their due diligence and discovered it's OK to keep it in. And I'm glad they did. It was fun.

[@inwex8350]

Love the way Charles Liu explains.

[@JP-xd6fm]

Right!!!???? it may be even better than Neil, I think Star talk should be Neil, Charles with Chuck and some guest, that's the perfect show to me!

[@chefjosephkowles575]

Neil is a blessing to humanity ❤

[@holy42cosmos]

He is over rated

[@holy42cosmos]

He thinks he is Carl Sagan but he is just a wanna be Carl Sagan

[@shelly_lee]

that he is, truely a blessing

[@jimbojimbo6873]

You on the other hand…

[@heresthethingyouguys]

Mostly to his bank account

[@fuckel98]

Charles Liu never fails to surprise me with his playfulness, it’s so casually interspersed throughout his speech that it catches you off guard in the best of ways. He’s got that off-beat timing with his jokes and references and I love it

[@beastboy1712]

I love how 30s in and Chuck already zoned out, and Neil said his name shook him back to reality lmao

[@humanform5354]

Yeah, noticed that as well. He had mentioned, a show or two back, that he suffers from depression. He said he takes meds to deal with it, could be a side effect...

[@sergeybrin6701]

Charles Liu is a rocker

[@abstractcullinairycreation7108]

Hi guys, ive been watching fairly regularly lately, but i wanted to say i really enjoyed the feel and flow of this show, i was excited to see it was a new upload. this group in this format is probably among the best of your content presentation and flow-wise

[@TheGiggleMasterP]

Thank goodness for all the brains involved in the making of this video!

[@rmoore850]

Bring him back. The four of you work well with one another with the perfect balance of knowledge in many similar, yet disparate fields and have fun while discussing high level science. I love it.

[@Razzie.]

Charles Liu is definitely my top #3 favourite people on this show. Neil and Chuck are the other part of that, of course ;)

[@lisacooke5928]

Love when Gary is on, he always has the best follow up questions

[@JP-xd6fm]

I'll pay for StarTalk permanent crew be this one + some new guests every time

[@cewkins721]

The whole crew together in a full episode! This one was amazing with wonderful questions, keep it coming!

[@whit1722_playz]

Hi, neil you are one of the best people on this planet.

[@TeaGarrison]

@@HopDavid As a non-scientist, I’m genuinely curious if you mean there are specific nit-picky things he gets wrong in the details of his explanations or if his concepts are completely out of whack? Cuz if it’s the former, then I don’t think that’s a big deal. He’s communicating science to the general public, not a scientific panel or grad class. I feel like as long as we get the general idea, he’s done his job of opening ours eyes, minds and horizons. Plus any curiosity he ignites can inspire our own pursuits to fill in any blanks. Regardless, I think we’re much better off having communicators like Neil than if we didn’t have anyone like him at all.

[@NeverDoneEver]

I was thinking about the pilot episode of Andromeda right before Charles mentioned it. I'm sometimes embarrassed about how much I know about science fiction and how much it must displace useful knowledge, so it's gratifying to see that Charles knows even more about science fiction than I do and is more successful than I am.

[@MrMackxl65]

I haven't heard anything more rnotivating than, "Get with the Century".

[@ilee92]

Currently on a deployment, eating Anthony's Pizza and glued to the screen. Us Vets are watching!

[@Xarpenter]

Thank you all for your service, and keep looking up!

[@EmpyreanLightASMR]

These videos and new titles and set-up are so slick now. I personally think it was a bit rough in the beginning but looks and sounds incredible now. Also, I waited nearly 4 years for you guys to reconvene with in-person episodes, but I want to extend my thanks for all the episodes you've released iin the hectic years. As someone who started the podcast from episode 1 many years ago while hiking on a windy wooded hill, I continue to this day to the best of my abilities, and it's been fun switching between the video and audio versions depending on where I am at the time.

[@LucidBhaskar]

man! This brings back so many memories.. feeling cozy with this conversation even in the middle of this hot summer here in Bengaluru.

[@tommyjinjin]

Need lots more Liu

[@barbaralachance5836]

I love how thru the years Chuck has become so knowledgeable ❤😊 amazing to see!

[@alro11]

what a great crew to discuss the mysteries of our lives and universe and beyond ! thx fellers❤❤❤❤

[@marcusbrown307]

Man this episode was great. Charles Liu is definitely one of my favorites.

[@Leftyotism]

"Are black holes places or objects?" is what keeps me awake at night!

Beautiful conversation, With great minds of our time

[@stephenhammond6962]

We need more like this! Face to face is so much better ! 💥

Truly one the best episodes!

[@stve5523]

damn!! Chuck Nice. -Kudo’s brother u really not only co host but taking your time to educated yourself- I been watchin your boyz since ya’ll started.. blessings 🙏🏽

[@JP-xd6fm]

Chuck Nice is a very smart guy no doubt!, to be a funny comedian you need brain but to be doing comedy beside Neil and co. that's premier leage category

[@randycook4364]

I love star talk. And that Outtro is perfection.

[@skeptickhan4239]

Listening StarTalk is my kind of Meditation & Yoga 🙏

[@_luis_rojas_]

Great show!!!!! Amazing watching you together..... It felt like a 5 minute show....

[@bearr4693]

That was one of the cleanest outros from these guys yet!

[@randomkindness1470]

I feel like we got a backstage vip access with this episode

[@jackparker2470]

THIS is the master lineup! Get these four together often! Bring in Janna Levin! Add Kate the Chemist too from time to time!

[@eddiesewell7337]

Also, Charles Liu is now my favorite startalk guest

[@dmytrospikin748]

It's just getting better and better every time ❤

[@marianagyorgyfalvi3659]

Yay a new recording!! 🙌🏾🙌🏾🙌🏾

[@no-relic]

What an excellent group of people and an excellent conversation

[@carguybikeguy]

Absolutely wonderful. Enjoyable, always.

Maybe my favorite one of recent videos

[@markblaise6256]

Great Episode

[@Momma766]

Love Love Love. Please keep up the wonderful work. Love everyone, this was another episode for the hall of fame.

[@Wooooahhh6272]

I love this format

[@ZorellUnderhood]

Dream team, you guys are the best. Could listen to you every day.

[@barobaro1]

Amazing episode. The only problem I had is how many times they interrupted poor charles, looks like Neil has thought his students well😅

[@DLegato]

Its not that often that a video that's a 40 minute long feels like it lasts a mere 10 minutes. That was very fun to watch.

[@Mehrunzebub]

Man, I love all of this so much.

[@rlivermont]

Charles is sure eclectic in his music! Love it

[@terrydavis5223]

Love you Neil!!❤🎉

[@jameswillis5431]

Great show (as always), and fantastic to see the whole crew together again - especially with Dr Liu, whose handy physics answer book I’m reading at the moment. Btw, is it just me or did Lord Nice look a little sleepy at the start of the show? 😂

[@Idellphany]

Great episode as always!!

[@loganmiller4919]

0:31 when Neil says “Chuck” it looked like Chuck was a robot just activating at that point 😭💀💀

[@JP-xd6fm]

🤣💯 At the beginning I though to myself, Chuck isn't ok

[@DannyJoh]

That was magic! So fun to watch you guys!

[@_KaiTheGamer_]

It was so nice of Dallas Featuring Worth to ask a question on StarTalk

[@randomuser942464]

I keep forgetting you release videos now so I've always listened to the podcast first. p.s. love everyone there

[@ryansoos4903]

Love the intro. Charles is so cool.

[@albertobarrios6276]

Hearing Charles say "press x to doubt" was not something I was expecting

[@lucaswitteveen4506]

the amount of knowledge Neil, Charles and the other friendly members of the geek squad could spread, if they made a show where they did dumb men stuff. shoot guns, messing with cars or maybe even do bar games. the physics, questions and theories that they would come up with and speak about seem really fun and informative. even the expansion in ways of thinking and observing would be incredible.

[@jtkachlmeier]

Chuck, I support you. It can't be easy doing what you do. But you can make it easy. Just be easy. Take care!

[@antoniologan7648]

Yaaaaaay Love this show! When will Star Talk come to Chicago?

[@cynthiachristiansen8803]

Thank you for your hypothesis.

[@sameera_viraj_K]

I love Neil deGrasse😍 Chuck as well ❤ Learning a lot

[@Eztoez]

You need to get Dr Emily Levesque on your show. She is an AMAZING speaker about stars. Particularly Thorne-Zytkow objects. Time to raise the bar, Neil.

[@joekenorer]

I love when Charles Liu starts talking Star Trek.

[@k.sullivan6303]

I would love to see you on Family Guy again... I would hope that you insist on humor of coarse, but also some kind of huge scientific teaching scene that would blow viewers' minds as well. Years later you could talk about the scenes on Future StarTalk episodes. I love what you guys do! I like your whole basic life approach Neil, and Chuck's humor and his relatable shock when you blow his mind. Your other guests are awesome as well.

[@robertsomazze]

Huge fan! Love the show

[@Dad_Woof]

So nice to see you guys in the same room

[@eha11oran]

Loved the outro!

[@jorgegaviria5670]

Amazing scientific show…

[@fishstix4209]

I'm a simple man, I see the 2 Chuck's, and I gotta click.

[@nunyabizness6595]

These brilliant scientists also talking about handbags. I love it. Hope Neil gets Shatner on again. Always fun.❤❤❤

[@MadDragon75]

StarTalk Plus? Yes please!

[@dosesandmimoses]

Love this one!

[@andrewhart6200]

With regards to the conversation @ 10:45.....it always reminds my small mind of looking at rims on wheels and how they can appear to be moving other than exactly how they are...It's different but similar kind of...

[@robertwhitephotography]

I have to say... Charles Liu and I are companions in music :) This was awesome guys !!

[@nathanmoore1893]

Always enjoy is when Charles is on.

[@blhageman]

Thanks Charles
