Cosmic Queries - Back to School Edition with Neil deGrasse Tyson

What do you wish you had learned in school? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice go back to school to answer questions about simulation theory, time dilation, white holes, the sound of space, and more!
What happens after you die? Where does oil come from? We answer fan questions from the Internet about what they wish they had learned in school. Explore the carboniferous era, why trees need microbes, and what we know about death. Are we living in a simulation?
What sound does space make? We explain the sound of silence, how old our sun is, and time dilation. We cover an essential question: do we live on Earth or do we live in Earth? Neil settles the debate once and for all. Could time travel exist? We go over different paradoxes and the trouble with doubling back on your own worldline.
In a nutshell: what is quantum physics? Why is your reflection opposite in a mirror? How does nuclear energy work? Hear Neil explain it both quickly and well. What is a white hole? Are there stars that don’t have galaxies? Or planets that don’t have stars? Could it be possible that the Big Bang occurs on a regular basis? All that and more on another cosmic queries episode!

Chuck said something very important early in the video. He said we are learning all our lives whether we want to or not. He added that some people learn the easy way (by educating themselves and reducing their own ignorance), some people learn the hard way. So true.

Chuck is invaluable to these episodes. About the time my brain gets in a knot from trying to understand difficult concepts, Lord Nice makes me laugh and relax so I can continue learning. Love you both!

[@KotDT]

The episodes with Lord Nice are my absolute favorites! Star Talk is an amazing and educational show. Thank you both for being such an inspiration to the entire world and probably to a few people zooming around it at 17,500 MPH!

[@Wardawg-]

Idk i cant watch a episode without Chuck. His energy is too enjoyable.

[@palvisharma4907]

For me, it's all the poetic ways Neil talks about science, the subtle manner in which he transcends or connects the binary(of science/art). There is a lot to learn from you. Hats off.

[@dadtipsandjokes]

I am so envious that Chuck is so lucky to have a friend in Neil and to do this show I love you both so much keep up the good work

[@DirtDigglerDetecting]

I missed school so much i went back at 40 :) i am 50 now and miss it again.

[@foxmountainstudios1884]

I absolutely adore what you do Mr. Neil! In my mind, you rank as the Bob Ross of science. You are in living rooms entertaining us with science! School is never out and you are the best bus driver. Also, Chuck is no slouch. I’d like to know more of his thoughts on white holes. I think he might be onto something 🤣🤣🤣The dynamic you share together is invaluable. Thank you so much! I love you guys!

[@christinet638]

My favorite two space talkers!

[@thermalrain_yt9725]

I'm definitely one of those people who miss school. I was happy with summer breaks but I was sad school was gonna end. I loved learning. I didn't have many friends but was friendly with everyone. We all knew each other. 300 or 400 people we grew up together. Clicks existed but it wasn't very strict.

[@harveyrants3637]

I loved being in school! High school introduced me to the worlds of calculus, abstract algebra, and so many other worlds of mathematics and physics! That's why I'm here at this channel. Lifelong learning!!! Thanks Neil and Chuck! BTW: Get Hannah Fry back for a math show. She's my favorite mathematician!

[@nrxchito]

This is encouraging to read 🤩 I hope your bond with learning continues to fortify your life & flourish ! Enjoy your beautiful life 🎉

[@MrHucast]

I love those black and white jokes Chuck spices up the show with now and then. 🤣 This kind of humor has gotten far to rare nowadays. Keep goin, man.

[@danielalex4637]

This show needs a co-host like Chuck. He is us, and helps bring complex notions to the mass.

[@Schrsmnymkr]

Love this show, while I'll admit I'm not as informed as Neil on these topics, his breakdowns on the topics are awesome.

[@tarmstrong9906]

I know it. Just simple conversation and lecturing, no fancy simulations, no high dollar graphics, just amazing raw intelligence is so much better.

[@camilocalderon2091]

The best science show, available to everyone.

My old boyfriend used to say we were in the university of life.

[@infamoussyn82]

Wish Neil was my teacher in schools.

[@Jager-er4vc]

“You’re speaking like a person who has confidence.” 🤣🤣🤣 Chuck is hilarious!

[@CrashingThunder]

I appreciate the frank conversation about life/consciousness and touching upon how its temporary nature is what gives it so much value. I feel like it's always hard to speak candidly about this kind of stuff (and especially so publicly and with the reach this show has) because religious and cultural norms can create such a negative backlash to anything that undermines people's beliefs. So in short, I just really appreciate how matter of fact you are about it. It really *is* simple, and it feels like so many problems in society could have been avoided if our cultures weren't so socially acceptive (and in many cases welcoming) of belief without justification.

[@DarkestVoid]

I’m not religious in the least bit I do think there HAS to be something after death we just have no way of proving it. We can’t see what happens when someone is dead from the person who died’s perspective. And that state of where there’s nothing we don’t know how long that happens. Like Neil said we don’t have a conscious awareness before we exist so who’s to say something doesn’t happen to where one day we suddenly become aware but in another person’s body. I feel out of all things the most likely scenario is rebirth. I see no possible way where we die and then there’s nothing at all. There has to be something else.

[@edbass2769]

I was disappointed that you guys didn't at least speak of the common and relatively consistent experiences of near death patients.

[@njones420]

@@edbass2769 These experiences are happening when there is still electrical-activity in the brain, and demostrate what happens when different areas of the brain begin to shut-down...It's easily reproduced by g-force testing or psychoactive-drugs. The experience tells us about how the brain fuctions, but nothing about an _afterlife_

[@njones420]

@@DarkestVoid There really doesn't "have to be something else" , it's just chemicals and biology at work. Do you think trees go to a better place? What about bacteria? what about things that are so close to just being simple chemistry we don't even call it "life", like viruses? Make the most of it, the time after you die will be _exactly_ like it was before you were born ...

I love learning... once I stop learning I'll be pushing daisies. I also enjoy teaching what I know. From computers, fixing cars, carpentry and riding motorcycles. Now I'm a farmer. Making trebuchet to entertain me and the dogs. Because trebuchet!!!

I love learning while being able to move around. It was hard for me to sit still in chairs at school. It is a wonder of the 21st century that I have access to Dr. Tyson exploring these topics! Chuck offers just the right mix of curiosity and humor to bring out the fascinating points of your subjects. Great team you two, ty!

[@robbin.bankss]

you sit still in school because that's the only way you can truly and accurately retain information. your brain can't cement your learning into long term memory if you're busying it with other tasks. watching these videos while going about your day may be fuel for curiosity, but it's a far cry from learning and retaining information.

[@robbin.bankss]

to prove my point, can you summarize what this video taught you about time dilation? WITHOUT going and watching it again? no, you can't. because you didn't learn it, you just used it as bubblegum for your curiosity. nothing wrong with it.

[@firebird2]

@Samantha Loughborough Ummmm, Howard Gardner's work in this area is over forty years old. You may have trouble learning while doing other tasks, but don't assume this is true for everyone.

[@robbin.bankss]

@@firebird2 regardless of your preferential methods for learning, if I read you a list and ask you to recite it, you're going to repeat it more accurate if you focus solely on my words, rather than if you were folding laundry or some other rudimentary task. and that's only an example of your working(short term) memory, not your long term memory retention. your brain has a limit to how many electrical impulses can be sent effectively.

[@firebird2]

@Samantha Loughborough I don't know what your background in neurology or education is, clearly it is limited. You are focused on memorization. Learning is so much more.

Could you please have back to school more often, may 3x yearly?

[@manavagrawal720]

Big fan of the show, a quick critial feedback... The questions or the genre of questions seems to repeat almost all episode. Maybe we can pick different sets of questions. Also, guys I've a suggestion- please start explaining equations so that along with understanding the concepts we can also see the application. For e.g. F= gm1m2/r1r2 | Here if Niel can help us understand how was the equation derived and why arranged this way mathematically and conceptually. Might encourage me at least to not just understand but apply.

la primer parte del episodio fue muy importante para mi, mi padre, hoy cumple 20 años de muerto, pero sus dos últimos años los pasó postrado en una cama luego de un derrame y muchos subsecuentes derrames lo fueron reduciendo, fue duro ver como su vida y lo qué él había sido toda su vida se iba desvaneciendo hasta que su cuerpo se dió por vencido. escuchar estas palabras de Neil me removieron un poco pero también me hicieron recordar con cariño el hombre que mi padre fue. un fuerte saludo desde Colombia.

Neil said something that reminded me of a quote from a book called Brother West: Living And Loving Out Loud." Don't remember the name of the gentleman who said it but it was, "life after death is no more problematical than life before life" and I think that's a really beautiful outlook.

[@wattj2]

I am troubled by Neil's explanation of mirror flipping. The reason that (flat) mirrors 'flip' us horizontally and not vertically is that they don't flip us at all, or rather, they flip us in the plane of the mirror. In physical space, in order to turn something front to back, we must either rotate it vertically, flipping it top to bottom AND front to back, or rotate it horizontally, flipping it left to right and front to back. Since we don't ordinarily see people flipped top to bottom and since we can very quickly confirm the vertical orientation of the self in the mirror, we intuitively expect the left-to-right flip, and it is the absence of that flip that we notice. Am I misunderstanding this? Or have I misunderstood the explanation given here?

[@brendanbrouwer7899]

No i was wondering the same thing, ive always learned it switched front and back. Not left and right

[@ojosh89o]

Been catching up on the show one u discussed the science behind time travel in back to the future and id say even if the tech was available its still impossible not only do u need the right orbit world line time lime but also cosmic drift and think that even gravity waves can throw a wrench in it

[@christinet638]

[@aitarun]

i think time ticks slow for us as we are closer to high mass (earth) but fast for satellite as they are away from the mass. I am not sure if the sattelite speed makes time slow in sattelites. Because i think gps sattelites are geo stationary.

[@jerryjohn7834]

I have learnt a lot from this Edition and only look forward to learn more. However, I have my reservations on the question of whether we live in or on earth. First, I think we should appreciate that the word "earth" simply means "ground." For me, it is safe to say that we live on Earth because the primary meaning of earth was the ground we live in. This word, however, changed in the scienific world to mean the whole mass of land, sea, and all that encompass the planet (Considering all other planets were being named from Greek gods except earth). So going back to its use in language, I still think it's imperative to say that we live ON earth.

[@markh3271]

As to time travel, is it you can't travel back from a starting point of the construction of the time machine? Can you travel forward in time and then return to your starting point? You would not be changing anything pre-construction but could affect the future.

[@REX-HOMINIS-THE-GAME]

Doppler effect for light waves is what Tyson is talking about when reffering to space-time dilation in reference to objects, by separating the speed of one, into their own speeds of space and time, relative to the actual space-time speed. The space in between and any object in it is subject to a doppler effect, which is what time dilation is. I'm not including gravitational effects for the light waves as they travel from point a to point z in my equation yet.
