[@darth_vyper]

I love Dr Tyson's delivery method of advance thoeries, makes me feel like I'm temporarily intelligent

[@rajgill7576]

peefectly described lol

[@bobbydeuce6486]

Chuck does it best. After Neil finishes a speech or long winded explanation, Chuck is just like “whoa!… 🤯”

[@DerGrueneBaron]

i hope they never stop making this podcast

[@mcrettable]

it's extremely easy and probably doesn't cost that much so if they stopped it would probably be for other projects or laziness

[@humanbeing2009]

Yes! Should be timeless just like the universe :-)

[@spaceman5089]

30 more years for grandpa Neil

[@And_Rec]

das Dilemma you had to call it back then... 1 year and a new episodes only last week...

[@jeremikossak9553]

[@brandonsteinbach4208]

It's such a shame that we will never get to see Neil Degrasse Tyson interview Carl Sagan. What an epic interview that would be.

[@BlacksmithTWD]

My favourite answer to the question : "Do you want to live forever?" is : "I don't know yet ask me again after 500 years".

[@theElrin]

Not only is this worth listening to it’s worth listening to AT LEAST twice!

[@OasiszGaming]

This show is what the world needs, truly hope it never ends.

[@TheWeatherbuff]

Love the podcast and glad I found it. I'm a meteorologist by training and trade, but I also have lots of audio experience from working on Radio. Suggestion: There's a little switch on your mics. Make sure the switches are set to the "/" mark. That will sharpen your voices a bit. Things sound a little muffled to me. Also, those RE-20 mics can be fitted with pop-screens to take care of the occasional "P-Popping", a common problem in Radio. Thanks Neil! Keep up this program... we need more people to be inspired to use their brains.

[@ThomasTT87]

Listening to Neil Degrasse Tyson for 45min? Yes please!

[@MrClaysta]

About 5 hours a day for me!

[@paulmataruga6558]

Haja

[@buddyzmama1]

I've been listening almost all day, love listening to this man speak, always learn something new

[@christinebowen2334]

can’t wait to see you on Wednesday in Richmond VA!

[@Canzandridas]

In spanish we call'em "Sol", "Luna" and "Tierra" so that part about their names fascinates me in a weird way lol

[@jotacerezo9963]

@@spiguy tierra*

[@AgustinGiannattasio]

Yeah, and we also call "luna" to other natural satellites, so I am still wondering what our Moon's name is

[@Baleur]

In swedish we call em "Sol", "Måne" and "Tellus", but most commonly "Jorden" which directly translates to the word for "Earth" or actually "Dirt" xD But yeah, "Sol" is a very common word for our sun in many many languages.

[@stephjovi]

@@Baleur are the articles male or female for sol Måne and Tellus? Because in german it`s the exact opposite of the roman languages and therefor the complete opposite association. So I`m wondering what it`s like in swedish

[@Morpheux1]

That because Spanish is a Latin derived language, so would be similar in the other romance languages (French, Portuguese, Italian, Romanian, etc.)

[@tiafoxxx1]

I like this guy more just because he actually seems to enjoy learning and listening as much as we do. Not as many interruptions :3 I also just like his voice

[@dirtywizard77]

Very informative and enjoyable listen as usual. Thanks for everything

[@chadcansler2211]

He should go by "your friendly neighborhood astrophysicists" since he live in NY

[@WildlifeWarrior-cr1kk]

No

[@skyliner32gtr65]

NEIL DeGRASSE TYSON your the first and only person that actually made me interested in listening to science, specially astrophysics. I was never interested in stars, planets, space, universe and galaxies.... I'm not smart nor young and never once have i ever felt bored listening to your explanations and interviews , you sure know how to inspired and connect with others making everything science interesting... The only reason i subscribed to this channel is because your the actual host, i thank you for sharing your knowledge with me and everyone in this universe and beyond...

[@Dartwith]

this is the best guest host yet! he's super funny and has a way of actually keeping NGT on track.

[@salvadorbello844]

oh buddy...

[@gambate1000]

I think he definitely knows the questions and their answers beforehand

[@11kele]

Yes I remember watching about that star and hypothesis about drawing energy from the star on TED. Now I realized that Kepler has actually found the location of Nidavellir... Awesome

[@radioactivespaghetti3416]

Neil I dont think the question about gravity waves and a mile piano sting was about seeing if a piano string produces a detectable gravity wave. He is asking if we could use a mile long piano string to DETECT a gravitational disterbance in spacetime. He's asking if the gravitational disterbance would vibrate the strink.

[@MsSomeonenew]

It would certainly vibrate, but we are talking less then the size of a proton. So it would be impossible for human senses to detect, you need high precision gear and vacuum to try and eliminate all other factors.

[@Doomroar]

Oh in that case it would have to be way, way longer than a mile, and at that point it would be harder to keep it tense and straight.

[@Aandemaat]

I was looking for this

[@LovelyAlanna]

if we were able to detect gravitational waves with a mile long piano string I think the gravitational waves would be strong enough to destroy earth or something like that.

[@thekaxmax]

Yup. It's not going to be sensitive enough. They barely get a response from long laser beams with detectors sensitive enough that they have to account for the gravitational effects of passing traffic.

[@Kekslord101]

If you are drunk, do not watch this. I am still cleaning my brain off the wall.

[@zemorph42]

And Cheryl's brother!

[@juseschrustfush]

Lol

[@acostafeliz]

That was driving me crazy I couldn't pinpoint where I heard his voice before

[@bambitazilla9464]

Yeah he’s a downer. I thought he’d be funny, but he’s boring.

[@petramakler8733]

I really love this show.

[@angelo5946]

Nice. Another day to learn and be fascinated............

[@eastlink20]

Chuck has a hilarious joke every 100 sentences he says. With Eugene I can't help but laugh my ass off the whole time. I'm not totally wrong

[@AL-SH]

Microtubule obvious difference between a black hole and a white hole.

[@mairajamil001]

I dont know why the two need to be compared, they're entertaining in their own ways. But i find Chuck's enthusiasm and humor very essential to the show and do not enjoy episodes nearly as much without him.

[@sherrymanning1116]

I like both

[@mjlpyle]

As a Mexican; Im sorprised and exited to know that the names of the Sun, Moon and Earth are the ones we use in Spanish (with the exception of Terra, we use Tierra... almost the same)!!! Thanks for that piece of information!!!

[@wendycontreras4850]

Hi. Regarding the areas of the universe where time could be melting reminds me of The Persistence of Memory painting by Salvador Dali.

[@brupster]

Nice episode, a lot of mind-boggling things got unveiled to me.

[@Julian-to7ro]

So interesting, I hope StarTalk goes on even after the universe will end :P

[@dralin350]

I'd love to see the calculation of the different levels of time dilation. Earth vs center of milky way, or Earth vs the void between galaxies (between Milkyway / Andromeda for example)

I love your star talk mr de xxx

[@miniecosytems5225]

I suggest for the next cosmic queries episode do the topic “Energy Generation”

[@xXpezcoolXx]

I can only think of Led Zeppelin and their Immigrant song when I hear StarTalk's intro always waiting for that "aaahh haaaaaa aaaaa" XD Love you guys keep up! The album is also called Mothership so it kind of make sense for a space talk :P

[@theloner6063]

Nossa lingua, assim como o idioma espanhol e italiano, derivam do latim ...e apresentam muitas palavras que podemos entender dessas outras culturas. Acho isso bacana.

[@WASDxMerceless]

26:12 I think they misunderstood the question that Jared asked. He asked if it was possible to observe gravitational waves using a mile long piano string, not create them. It's a good question, kinda wish it was answered.

[@Fecal_Eruptions]

I'd like to know if there's a hypothetical way to simulate the effects that speed has on time. In other words, could we simulate the slowing down of time effect that traveling very fast creates? Would it possible by simply spinning really fast? Or maybe create some kind of pod which is surrounded by something that creates a strong electromagnetic field, and spin that outer shell really fast. Something of that nature. Maybe it would require a small circular track which would mean actual travelling distance vs. spinning on a single point.

[@RapidDominance000]

did Eugine just make a my name Jeff joke

[@ivanjdrakov1957]

I really, really, really like this comedian.. He is more mild and more like for this show, cz it's all serious and stuff.. 😁

[@donaldfreeman239]

Neil he was talking about the gravity event hitting the mile long string and then we detect movements.

[@Timbo6669]

ikr! That kinda annoyed me. Dr. Tyson should've known that. ie. Replacing the laser[LIGO] with a piano string of similar length to detect Gravity waves. [for the rest who didn't pick it up].

[@Kevinvikram24]

37:10 the movie you're referring to "In Time" (2011) where time is considered as a commodity

[@RomanceTheWorldV]

Eugene!!!

[@intravenousdmt8977]

Great Bolshy Yarblockos he sucks and is dumb and doesn't get Neil's humor

[@domenicpfeiffer]

I have a question I couldn't get an answer to : Assume we life in a Simulation like in the Simulation Hypotheses explained. In this case, gravity as well as approching the speed of light is a result of insufficient computing power from the host, so relativistic effects take place and time slows down. The more mass an object has or the faster it gets, the slower time pases for things near it and/or itself. Now to my question : If mass can slow down time because of an enormous need of computing power required, couldn't human-build computers do the same thing an slow down time as well because they also produce workload on the host computer?

[@cody2198]

the movie you were thinking of is "In Time" with Justin Timberlake and Amanda Seyfried from 2011

[@AL-SH]

cody2198 And Cillian Murphy a.k.a. Thomas fooking Shelby!!!

[@zacharycollins9485]

And the other one was "Elysium" with Matt Damon, i think.

[@cicad2007]

Btw, Transparent aluminum does exist, It is a form of aluminum that is see-through. Most commonly someone speaking about transparent aluminum is referring to AION (aluminum oxynitride), a ceramic alloy. However, aluminum can exist in an elemental, metallic form made transparent by bombarding with a soft x-ray laser.

[@kilo-da-great8799]

Neil are you hiring 👏

[@Disavowed_Rogue]

Powerful NGT

[@Chinchilla_in_the_Villa]

Ah a fellow Joe Rogan fan :)

[@jackd42o]

Great stuff

[@Iridehier]

If the formula for Dark Matter were a function of the density of visible matter would we be able to prove or disprove that? It would go something like this, as atomic structures increase proximity, bosons responsible for the gravitational field interact as a square of their decreasing distance divided by total distance multiplied by the permittivity of free space. Is it possible that our current calculations for Mass vs. Gravity are biased assuming that all forms of mass exhibit equal gravity? Perceptible changes would not manifest until extreme densities are reached.

[@leec9109]

A key issue with commanding all the energy of our host star is that we would, essentially, block out the sun, which would be catastrophic to our world. At best, we would likely be able to safely harness 25 to 40% of it, and that is specifically calculating that we can predict all shifts in orbital change... I think that a better solution, and in support of the next moon voyage, would be to harvest solar energy from the moon, and transport it back to earth, as we can safely predict the amount of exposure to the photo-voltaic cells to a measurable energy transfer back to earth.

[@tuberyou1149]

Is the Universe so fine grained that it is essentially smooth and continuous?

[@websurfer352]

So, my intuitive understanding of a causal set is that a causal set is the smallest possible scale at which the causal order holds!! Causal order because spacetime is causally ordered due to the time element of spacetime?? So, I take it that a causal set would be on the order of the Planck Scale??

[@paull4135]

30:02 "long, hard and deep" 😂

[@ZillionZillions]

Giggidy

[@samevans2468]

That "IN TIME" movie reference

[@Isaiaswolf66]

So we spanish speakers got it right Earth= Tierra Moon= Luna Sun= Sol

[@khosKarm]

Wolfgang goethe spanish comes from latin, so thats kinda normal

[@sticky4158]

And it’s Terra, not Tierra for the Latin... if we are being specific

[@-8_8-]

I love how this comment irreverently disregards the respect for antiquity shown by the decision to keep the names Latin. I guess that might not be clear if you're not a native English speaker. Consider if your country had an emergent technology and decided to name everything in Greek. You'd be showing reverence for something that happened in Greece.

[@krazytaxicabbie]

The movie is called In Time. ;)

[@patf8845]

I'd love to see ndgt as himself on bobs burgers.

[@wildlaborg]

At 2:12, Neil said that it is theoretically possible to travel back in time, unless some "universal law of physics preventing that". This law might be the conservation of the energy - if some object goes back in time even 1 second, this means that in the past you will have two objects (doubling the energy according to E=mc^2), while at the present, this object virtually disappear, so suddenly energy is destroyed at present, while it appear in the past - adding to already existing energy of the already existing object (for example electron, proton... atom, macro object...). My thought is that time travel is not possible.

[@urbanConcept7]

hey Neil, I have had a theory for years that gravity is weakening because the fabric of the universe is expanding/being stretched, the fact that this may also be diluting the higgs field also gives credence to the idea that gravity weakens over time. The higgs field being diluted is also reducing mass over time which would also reduce the effect mass has on the space time fabric too. thoughts? @startalk

[@brian_mcnulty]

That is what he said in the video.

[@FalconFXICCY]

It's too bad Dr. Tyson doesn't read these comments, but when he suggested that there may be a possibility that a weakening or stretching Higgs field could reduce the mass of particles because of the universe's rapid acceleration, my very first thought was that, this may explain the symmetry breaking that happened in the early universe, the reason why we have that inexplicable abundance of matter without its corresponding anti-matter.

[@leanderbarreto6523]

We need an update on this

[@Hamlet137475]

Eugene is back!

[@spacebendtime9173]

Never tought i had to correct Neil, sorry Doc: Earth: (english) Terra: (latin) Gea or Gaia (mythological name, as Gea was a goddess (geography)), Sun: (English) Helios: (mythological name), Moon: (English) Luna: (latin) Selene: (mithological name from a godess). Im sorry Doc, i am sorry, i didn't want to correct you but you got me started, love, a fan of yours.

[@willmpet]

To get to another level Dr. Tyson is talking about the Kardashev scale!

[@highstreet2535]

I support science... this is the only channel where i don't skip the ads

[@CyberiusT]

People keep asking about periodicity of Tabby's Star 'structure' and wondering why astronomers don't care that they haven't found one. Consider: observations have amount to very little time (only 4 years or so, I think); our best guess is a busted-up comet; comets orbit a *long* way out - for Sol that's the Kuiper Belt 30-55AU out, which makes the periodicity about 200 years.

[@jhamptonjr]

I'm 60 and learned the Latin names for the sun, moon, and Earth by the time I was in 4th grade. But I was always interested in space.

[@-8_8-]

I don't think they taught us anything but "the" Earth, Sun, and Moon.

[@JordanMillsTracks]

ohh i remember Eugene from flight of the conchords!

[@thiagarajang6813]

[@lamajaune6265]

[@ShamblerDK]

This is definitely the smartest comedian you've had on there.

[@Avocado_Gravy]

Didn't know he'd started his podcast stuff! You know its gotta be good when he'd only got 200-300k views, and lot of likes!

[@VR6NAVYVW]

With a dysons sphere, not only could you use light as energy but if your container a star I imagine it would be very hot, so cooling the sphere can provide vast thermal energy also

[@yigitkahraman2695]

Isn't space at ultimate cold level?

[@martin36369]

If the slowing down of time of an accelerating spaceship, is relative, & the Lorentz contraction is also relative, why isn't the increase of mass also relative?

[@zynthexthezane]

Can anyone explain me how objects of any kind sent from Earth can go past the Kuiper Belt?

[@lxwood505]

I have often wonder about the prospect of a Dyson's sphere. More specifically, if creating such a large structure would augment the gravitation properties of the star and will it reflect on its solar system. Would this effect the path of its satellites?

[@csgstormer]

Did anyone else get their mind blown about the question of space being continuous or granular? (If you're a math nerd, it'll make you question Cantor's infinite set theory - since math is supposed to correspond to reality).

[@Godfather061]

I keep wondering when Neil deGrasse Tyson will endorse Thorium Molten Salt Nuclear Reactors as a strong possible source of energy for the United States. I also wonder if Neil deGrasse Tyson that ever watched Isaac Taylor’s KZbin posts concerning space colonization and the idea of using an orbital ring is a method for getting material into space relatively cheap like a few dollars a pound. According to Isaac Taylor building an orbital ring is well within the current feasible technology.

[@MsSomeonenew]

NDT isn't really into sales pitches, he just explains current knowledge of the universe. The orbital ring certainly is within our capacity but we are talking super mega projects that would need to be funded by the entire world in the trillions, for comparison ISS only cost about 25 billion to make. So we are talking large leaps in social and political interest for this to even be a serious conversation.

[@Grizabeebles]

Also, Thorium reactors are the betamaxes of nuclear reactors. Nuclear reactors are already one of the most expensive methods of electricity generation and there's just not enough thorium to make it financially viable for wide-scale power generation for more than a couple decades. We're much better off in the long term going straight for renewable energy sources and fusion power. However, Thorium reactors would be _killer_ in small-scale generation roles. Especially if we ever get around to large-scale asteroid mining.

[@alloverdaplace2043]

Wow this is an old episode from 2015

That's ok. Enjoying it in 2019 :)

[@AnnaCentauri]

[@alycinannette2737]

I'm in love

[@timkamp6798]

Neil misunderstands the question at 26:11, the question is can you find gravity waves by observing a piano string, not generate them by vibrating one.

[@davidnelson2204]

Do gravitational waves loose energy as they travel through expanding space, like the red shifting of light from distant sources?

[@rohit6125]

Yes so that's by 1/R^2. Also why black holes haven't swallowed us and are be dormant.
