It is nice to see Neil DeGrasse Tyson is back. Nice to see you back in action man.

Glad Neil is back. He survived the bullshit allegations. Top Man.

Chuck is my favorite guest comedian. He is respectful with the guests and he always have an enthusiastic attitude towards the topic.

Needed some new Neil content in my life. Real shame Cosmos got pushed back, hopefully not too far.

I am glad this show is still on. I learn so much. Neil is able to make this interesting and fun. Wish my teachers years ago were all like him.

Yay Neil's back! Thought he was going to get the Vic Mignogna treatment from his allegations. Pleasantly surprised

I can't be any happier with Star Talk coming back. My day started pretty bad but this made it a billion times better

Am I the only only one who appreciated and acknowledged the 'out of the aether' joke by tyson?

I had never seen or heard of Janna Levin, but I’m in love now.

Oh? Wonderful! Thank you to StarTalk, to the enlightening Neil deGrasse Tyson, to the welcomingly funny Chuck Nice, and to the incredible and inspiring Janna Levin for engaging in this way. 🌻

Jenna is a superstar in her own right and I never get enough of listening to her. As Albert Einstein is another favorite of mine this video was a real treat. 👏👨🏼‍🦳

So happy you're cleared of the allegations! Love you Neil!

Makes me so happy to see you all doing your thing again. Star Talk has been a favorite for years.

Ive missed Chuck and Neil

I couldn’t ever get tired of listening to the beautiful way that Janna passionately explains about science. So inspiring, deep and technical… damn, you’re the best!!

Great show Neil, and everyone involved! Was very enjoyable to watch, thank you.

Until someone shows me at least one piece of legitimate evidence, Tyson didn't sexually assault anybody. We should never believe anyone who make claims based without supporting evidence. I enjoyed the show, and a happy birthday to Albert Einstein.

Neil is legit the best person ever. Everything from his voice to his personality and his sense of humor is all great!

Thank you, Dr. Neil, so much for this full video for us! Spreading it out, for sure!

It's so satisfying listening to these very intelligent people and chuck talking unpretentiously about deep stuff.

HI Dr.Tyson...Chuck...good to see and hear you again!!!😎😎

It's been too long I had Neil DeGrasse Tyson in my life, when will the next season begin? :)

Happy to see Neil back, picking up without missing a beat. Super stoked for Cosmos Season 2!

The last part where they talk when everyone collaborated to observe one specific event, is just heartwarming.

I miss you Doctor Neil DgraceTyson

Its been a GOOD minute I haven't seen from my favorite human on earth! I've been waiting, so good to see you Neil!

Welcome back Star Talk!

love to see full episodes!

I've heard most things about Einstein, but I don't mind listening to this women tell the story again. Loved the video, keep em coming.

a hope that things will go back to normal and youtube will be filled with neil's videos that will give you knowledge and maybe just maybe cosmos will be saved

Could listen to Janna talk all day. Awesome chat, thanks Neil.

I love conversations like this. Why couldn't these videos exist during my time in school? I would've gone face-first into the science field.

What an amazing discussion/lecture guys... inspiring and extremely educational how you added perfect elements of humor to relate to those who (like myself) are not astrophysisits. . or comedians.... Or hell, might know nothing in the least of this subject matter! But as always, you guys made it fun and entertaining... which honestly I hate to say is kind of the only way to educate people these days, myself included! I love this and I love you all for the work and passion you have! Please keep it up! - The Lovelace's from Memphis

Janna Levin is SO adorable! Chuck and Neil, you both are a super team! Thank you. :-)

Dude, all of you rock. Thanks 😊

Thanks to this video I discovered I live less than an hour from LIGO Livingston ! Incredible ! Plan to take a trip to this marvelous site.

Professor Levin is just a delight to listen to...

So I could have sworn I heard this before and I went the actual StarTalk website and found that this is just an edited version of a podcast done a year ago! Come back Neil! And quite trying to trick us with re-hashed content!

I can listen to this man all day. Who else loves Neil?

Janna Levin explained beautifully the sounds of universe and black holes. And her observation of Einstein's life is superb. Enjoyed this one thoroughly ❤️❤️ Neil is always fun in betwen

You guys look great. I've missed you. Don't ever leave me again!

3:34 The moment Chuck thinks : "Damn , I need to Google this one" ;-)

So Happy to have you back Neil!

Encore, Encore, ENCORE!!! If you don't love Dr. Janna Levin, then you just don't know love! She's awesome and compliments, Dr. DeGrasse's explainer so well. Bring her back for more episodes! Bring her back. Bring her back. Bring her back

Any news when will Isaac Asimov debate 2019 going to be? Also, how can I try to buy the tickets?

@24:40 "Get out!" "Move away!" jeez, that reminds me of the movie Event Horizon....

Wooooo! Love you Neil! Keep doing what you do man! Educate the masses and show everyone how awesome existence is!

This is such a well executed talk. So lively yet informing.

Yea! Neil is BACK! So glad to see you, don't let the snowflakes keep you down.

Albert Einstein’s Theories and equations basically birthed every current cosmological theory. Inflation Big Bang Black holes Time Multiverse And I’m sure I’m forgetting a few. That’s a legacy.

Thank you Chuck for that last question! I was waiting to hear more about the colliding neutron stars and i was afraid they would end without going in to it more but you saved it!

Welcome back Dr Tyson. Your talks and shows are entertaining and inspiring. Eagerly waiting for COSMOS. Love from India...

any news about the new Cosmos series?

Cool i was looking for a good video!

Glad to see you back!!!

Good to have you back

This lady is so smart yet so hipster looking damnn

18:46 For real, earlier today I was thinking, "Then what is the difference between a neutron star and a black hole, besides the obvious?" This is the first StarTalk video to have me burst into tears. Not helping is that I had a rough day anyway but I have for *YEARS* not understood what a black hole is, and now I think this video explains it perfectly. The size of the black hole, as explained by NDT in another video, is measured by the event horizon, but the event horizon, as explained here, is the edge of the shadow created by the actual black hole. There is nothing there. In another video, NDT explains that you would actually be conscious as you fell into the event horizon and before you die, you would actually be *aware* of not only your surroundings, but of quite possibly a whole other universe opening up before you, which can exist inside the black hole. (Btw, In his book "Death by Black Hole", NDT explains that spaghettification doesn't occur with every black hole, only smaller ones relative to your size; has to do with the size ratio of the black hole and you as a person.) Chuck Nice finally asks the question that no one else ever seems to ask, and that is: but when two black holes are colliding, what exactly is colliding. When Janna says, "Spacetime itself", I basically broke down. (On a rewatch, I still teared up - I think this is important stuff lol.) By the way, all shadows are 3-dimensional, but what we see and call a shadow a "shadow" is the 2-D image that represents the lack of light on, say, the ground or a wall. But the shadow itself is being cast like a beam of dark. So a tree in sunlight will have a 3-D shadow cast shooting perfectly straight from its leeward side (as it were) that you can, as Janna says, step in and out of without feeling anything. (What you would feel is the sudden lack of radiation emitting from the sun, which is why the shadow of the tree is cooler and more refreshing; has nothing to do with ambient air temperature. Source: startalk again!)

This video was much better and enlightening than I thought it would be. Thank you

I've been so waiting for him to return.

Actually Chuck’s question are smart, he is really paying attention

Great, now i gotta change all my passwords...

Great show! Janna, you ROCK!!

One of my modern time heroes discussing one of my all time favorite heroes! Mr. Tyson you are an inspiration!

YAY!!!!!

5:10 Neil when she says no to putting out on the first date.

thanks for the the awesome show.. again..

It was joyfull convo !!! #HappybirthdayEinstein

Me: ringing sounds in my ear Black hole: omae wa mou shindeiru

Its my birthday on 14th March!!!

My knowledge on Blackholes just increased by leaps n bounds. I'm amazed. It was a brilliant and open discussion. Thank you all.

Love this stuff 🤘🏻

I did a double take when I heard "Janna Levin" as "Jan 11".

Oh hi, Mr Tyson. -Pluto is a planet- What a lovely day, eh?

I'm Sooo excited to see new videos of Neil 😍😍😍

yeah! the man is back. good to see you again.

They mentioned early in the show that Eisnstein was alone in formulating the General Theory of Relativity, however there was at least one other scientist, the English Physicist David Hilbert that was working on a similar approach to Einstein's take. In fact they exchanged correspondence just before and after Einstein’s publication of General Relativity. There was some discussion in later years as to the degree that Einstein coud have stolen Hilbert’s idea but that has been discredited lately. Below an excerpt from Wikipedia on the main points of the dispute: "Before 1997, "the commonly accepted view was that David Hilbert completed the general theory of relativity at least 5 days before Albert Einstein submitted his conclusive paper on this theory on 25 November 1915. Hilbert's article, bearing the date of submission 20 November 1915 but published only on 31 March 1916, presents a generally covariant theory of gravitation, including field equations essentially equivalent to those in Einstein's paper" (Corry, Renn and Stachel, 1997). Since the discovery of printer's proofs of Hilbert's paper of Nov 20, dated 6 Dec 1915, which show a number of differences from the finally published paper, this 'commonly accepted view' has been challenged.[10] Whether Einstein got the correct mathematical formulation for general relativity from Hilbert, or formulated it independently. Points at issue: * The content of Hilbert's November 16 letter/postcard to Einstein is not known. It is however, clear[according to whom?] from Einstein's response that it was an account of Hilbert's work. * It is not known what was on the missing part of Hilbert's printer proofs. The missing portion is large enough to have contained the field equations in an explicit form. There are several competing speculations about the content of the missing piece. * Based on the above, it is not known whether Hilbert had formulated the field equations in an explicit form before December 6 (the date of the printer's proofs) or not. It is known from the proofs that Hilbert introduced four non-covariant equations in order to specify the gravitational potentials g g^{{}} and that this approach was dropped from his revised paper. Whether Hilbert ever tried to claim priority for the field equations - it seems clear that he regarded the theory of general relativity as Einstein's theory. What Hilbert thought he was referring to when he used the term "equations of my theory" about Einstein's research. Hilbert made a similar remark in a letter to Karl Schwarzschild.[B 1]"

Great, finally where a Nerd like me belongs

Good to see you back.

It's nice to have you back :)

Nerd out time

Celebrate Albert Einstein’s birthday, pi-day, and Stephen Hawking’s deathday?

Sooooo.... So long time Mr Tyson. Where have you been? Glad to have a new episode tonight. Best regards from France .

Sirs, Nice and thanks for making video..

Yes! Inject this into my subconscious as I drift into a Sunbeam......wait.

Janet is quite attractive :)

Great! Really enjoyed this.

Contemplating the leap forward that was General Relativity blows my mind everytime I think about it.

19:40 True that the image of a hole is a total misrepresentation about what is a "black hole"... The French were right on this.

When I'm around conservative theists, well, that must be how Einstein felt around the general public.

March is the monday of the year... but not now with Neil back !!! ♥

Albert Einstein also predicted today's economy. He said the 1% will control the news, media and educational system to intentionally make children Dumber so that they worship Authority. "Private capital tends to become concentrated in few hands, partly because of competition among the capitalists, and partly because technological development and the increasing division of labor encourage the formation of larger units of production at the expense of smaller ones. The result of these developments is an oligarchy of private capital the enormous power of which cannot be effectively checked even by a democratically organized political society. This is true since the members of legislative bodies are selected by political parties, largely financed or otherwise influenced by private capitalists who, for all practical purposes, separate the electorate from the legislature. The consequence is that the representatives of the people do not in fact sufficiently protect the interests of the underprivileged sections of the population. Moreover, under existing conditions, private capitalists inevitably control, directly or indirectly, the main sources of information (press, radio, education). It is thus extremely difficult, and indeed in most cases quite impossible, for the individual citizen to come to objective conclusions and to make intelligent use of his political rights." - Albert Einstein

His accuser should've detached herself from the #metoo movement. Was a bad idea to not take that important step.

So glad you're back:)

Idk how I haven’t seen this before now. This is like my dream conversation!!!

Sooooooooooooooooo are they going to talk about Einstein or blabber on about random shjt?

Great session!

Good to see Neil again!

That information about the cubic centimeter of electrons blew my mind

Chuck pulling a great question out of his...ether at the end there! Great stuff!
