For someone who's been to space he's really Down to Earth

@GOD's BEAUTIFUL FLAT EARTH ????

YOU MEAN HIS LIES ? as if you can go there and verify it or anything else he says. I would give him to much creditability. Just because he's being nice doesn't mean he's telling the truth. It's kind of like, Stabbing someone, Twisting the knife looking into their face , twisting the knife all while smiling and asking you if your ok.

Bruh

🤦🤦🤦

Aahh I get it! Very clever.

Wow, I really never had thought about the sun being essentially the loudest single source of sound in the solar system… It's just that we can't hear it because of what commander Hadfield explains here. So. The sun is SUPER noisy! Wild stuff!! As a side note, I am incredibly honored to have met commander Hadfield at a book signing in Dallas about seven years ago! Still a highlight of my time here in Dallas (okay… One of the highlights of my life :-)

Thing is we never get to hear it because. No human can survive a second without a spacesuit in space

And the moon is a self-illuminati orb thus man has never set foot on the surface of the moon!

Imagine if sound could travel through space, we could be all deaf by now by all the explosions happening around us 😂

If you listen to the RF output of the sun, it is deafening.

they way he explained relativity to us physics noobs was so good, it’s easy to digest. i wish my teachers were like him

I think Chris mentioned being a part-time musician to be more relatable to the average person, and to show there are artistic interests in his life in addition to the sciences. Seems like a great guy!

@Victoria I will wait for you to give me one proof he did. Other than staged sets and wires. And my dream in Canada where I live would be to meet him , and have him swear on a bible he was in " space" , or any man for that matter.

@Langley Believer how did you know?

@Thomas Morgan Im not saying he wasn' t playing a guitar , but he wasnt in space.

​@Langley Believer He covered Space Oddity by David Bowie in orbit ..

He might play a guitar but sure wasnt in " space" .

It's surprising that i finished the video and i actually learned something even though im not that into space talk... he's like one of those teachers that no matter how hard the subject is but when he's the one teaches it you'll understand

Chris: It's actually not like that Me: nice Chris: It's much worse Me: *OH NICE*

The sundial destroys the globe.

Hahahaha

I love ur username

🗿

@Nicole Martin five times a day, apparently

Его объяснения это нечто! Вот бы моим детям такого учителя физики в школу! 👍

nice profile pic

I am amazed at his knowledge, calmness and his way to explain and demonstrate his answer. Its amazing and Im grateful for the answers

@Lyn Kurt Bs!

@big labowski bs?

It delights me how many people here know space is fake.

ACTUALLY IT SMELLS LIKE BS

He seems to be a very cool guy even if he is destroying some of my favorite sci-fi tropes.

Chris is amazing! He’s one of the best guys to explain space stuff.

He looks like that one substitute teacher that everyone wants

That has no idea about reality.

Speak for yourself

So true

He looks like Omni- Man

He DOES!

I've never thought about what space could smell like. Makes me think of how much exists we never imagined existed

@Dean G 🤷

The question is, how does *he* know what space smells like? Has he been into the vacuum of space and inhaled its contents? The answer is no. Why? Because if he had he would be dead.

Really clearly and entertainingly explained. Good guy.

An extremely interesting video. I absolutely loved it.

All I can say is: Dr. Hadfield thank you for your service.

He answers these so nicely. Instead of saying "No, that's impossible, those movies are dumb," he shrugs and says "Well, we don't know how to do that yet!"

I won't eat a cowman but I will eat many cows man.

The sundial destroys the globe.

ACTUALLY IT SMELLS LIKE BS

well that is just to make people like him more, it's well tested psychological tactics beyond videos like this. "Oh he seems like such a nice and great man i can't ever imagine he has ever told a lie in his life"

What happens if you have an itch in your nose while in the space suit ? Or you suddenly have to sneeze ? Do you just have to quell that feeling using mind over body , or is there something built in? I know my question is more practical & less, I dunno, philosophical, but I’ve honestly wondered that forever

So cool. I think the first step to solving the gravity problem is to generate immersive ferromagnetic fields on the ship. Something for NASA to think about.

Love him, one of the modern legends of space travel, he used YouTube to teach and inspire a whole new generation on the human races place in the stars, who else can say that?

Such a well spoken and insightful man. Thank you for taking the time to explain things in detail.

I could have a conversation with this man all day and still not get bored.

@asleepinthealley the difference between 1 atmosphere and a vacuum is less than a thousandth of the difference between 1 atmosphere and the bottom of the marianas trench. it's far easier to have 101.3 kPa surrounded by 0 kPa than it is to have 101.3 kPa surrounded by 110 MPa. that's not even what globalism means

The sundial destroys the globe.

@HolyDiver yep that's my name and subscriber count thanks for letting me know I appreciate it.

Isaac Tyler 6 subscribers

@Michael Smith I mean yeah I guy like that would probably get bored with most of us including you as well. At least I'm still learning about a fascinating thing and who knows maybe he enjoys teaching people.

Thank you! THAT was very informative and interesting. Also everything was explained very understandably. Good stuff!

Wow! I've NEVER understood the Einstein clock thought experiment until he explained it! Thank you Chris that makes SO MUCH MORE sense to me now!

I actually love this guy, i watched all his videos in space. I always loved that honey in space video. He's very cool.

That line "gravity is pushing me down" was very precisely said Space-time curvature!

This man would actually be a good teacher.

@dj traBBiz Ramage plot twist: we live in the matrix and actually we're all just computer programs and nothing is reality (not even us)

What do you think he’s doing here ?

Yea for the annual pay no😂 he’s better off astronomy

Is a good teacher

I think he’s the only one that could explain black holes in a way I’d understand

Astronauts are so down to earth.

This was quite informative and fascinating, very cool.

Science-supported answers! Love this guy.

i never thought about the fact that the sun is constantly *screaming* and we just can’t hear it because of how sound travels. that’s so fascinating

@ItsATrap! No, that is not why the speed of sound varies with altitude. The speed of sound varies with temperature and temperature varies with altitude. That is why the speed of sound is lower at higher altitude.

The sundial destroys the globe.

You mean soundwaves not sound.. Or you must say that sound travels at waves and the waves you can only hear with your ears or via microphone.

Rick and Morty explained this....

This was interesting. Chris seems very “down to Earth”……

Brilliant Chris loved what you spoke about it was well informative, thank you 😊 👍 🙏 😎

So I did quite a lot of thought experiments on explosions in space, and non sun explosions (like a space-ship) would contain air and particles that would explode and hit the hull of the space ship you are in, and that would carry sound (only once it hits your hull). I have no idea exactly how it would sound, but I believe there would be something.

sure, if sound travels through to you, you'll hear it. how well it'll travel through to you is probably a question better posed to jack swigert, jim lovell, and fred haise

In the spaceship there is air so sound would be able to travel right ?

I love this guy. Can he have his own show?

My mom actually went to school with Chris since he lived in Canada. She said that he always had his nose in a book! It’s crazy where people can end up, and how successful they can be!

The sundial destroys the globe.

Morgan Whytesay yea

why is everyone assuming that this person is lying? There is such a thing as before fame, so of course famous people would’ve gone to school with regular people before becoming the people they are today.

Finally after reading and hearing so much misinformation over the years about space travel, all those questions and more were answered correctly. Thank you Commander Chris Hadfield!

I love explaining of the first myth however how do you know have u found anyone lost in space or test what would do to the body has this happened if u do how long do you have to get back into the ship or is it that instant and again has these results there to know for sure

Thank you for sharing your experiences here. I would have loved having you as my professor.

Absolutely brilliant, thank you Mr Hadfield.

Its nice to see educated people sharing their knowledge with us.

The sundial destroys the globe.

@Imodium so im guessing youre breaking out of this system right cause youre not just a sheep on youtube watching this just like us. Go on

@D J Nah, we did go to the moon. You were wrong there buddy. But I do believe you got some education since it's been like almost 3 years now.

Great video. Invaluable data!

That clock explanation about theory of relativity is incredible ✌️✌️ Blown my mind

The only ways to hear a star, besides through radio waves, would either be going into it's chromosphere, or being hit by enough particles to negate the vacuum of space. Either way, a human observer would be dead, though maybe with enough time we'll have tech to allow audio recordings of stars (or at least of Sol {The Sun}). It's just as, if not more, likely as ever actually discovering plausible FTL travel. There could conceivably be a universe full of life, with no possible way to ever actually physically interact with each other on a major societal level. Generation ships could be the only possibility. I hope not, but it's the most likely current scenario.

Questions I wouldn’t think to ask, well answered. Thanks.

Imagine being able to tell your grandkids the stories of your spaceship.

The sundial destroys the globe.

If it weren’t for Teddy our kids would have already been traveling in space.

He’s an excellent actor. Love him.

Chris Hadfield is so amazing! A person who is well-spoken and insightful with a calming attitude, has knowledge about the world we live in and everything that surrounds us, and experiences things beyond the imagination. He is really living the life that he has knowledge about.

he's actually a part time astronaut and a full time musician.

@LokimonWasHere dont be like that what did he do to you

No, he's a full time lying actor.

I feel so genuinely sad for the people who asked some of these questions...

He looks like those teachers that say " there is no such thing as a dumb question"

I could challenge that assumption

😂😂😂

The sundial destroys the globe.

Bruh

there are no dumb questions, only dumb people. asking a question can sometimes reveal how little you understand. and in certain situations harm your reputation. that expression is more for 3rd graders.

On the last one, the germs, I used to be involved in making machines called 'Cold Isostatic Presses', which is a simple 3 dimensional press, being that things are pressed via fluid surrounding them being pressurised. Pressures of 100,000 psi are common, mostly used to forge various materials in powder form to solids, and one of their uses is pressing food to those extreme pressures for space travel, as the pressure kills all the bacteria during the process, interesting stuff.

Wonderful video, thank you Mr. Hadfield

Chris is such a chilled guy. I would love to eat some space cake, or mushrooms with him on the ISS.

If there was a way we could design a slippery space bubble that we could place in space we could use the sliding space bubble to slide quickly through space

I love how he mentions he’s an astronaut, spaceship commander and space walker while also adding part time musician just in case we needed to really get an idea of how brilliant he is

4:00 he explained Einsteins relativity all wrong though. The concept is lag or latency. If you had 2 clocks, synchronous to show same and move one clock 1 light sec away, it would show different of 1 sec. If you move the clock two light secs away, it show a difference of 2s and so. They don't age differently. It's just lag or latency.

He didn't mention hes a doctor, engineer, fighter pilot.

Burnt steak smells like space, or butt.

I love the speed of light portion. He has no evidence to prove people on earth would age faster or that you would age slower. It is a theory....a guess.

I never picked up that all these movies with interstellar travel were “freezing” the characters. I always thought that they were being placed into a coma like state, but never frozen 🥶 😂

what a cool intelligent down to earth dude even if he was in space

I would love to sit and watch all the cool space movies with this guy like Armageddon, Sudden Impact, Martian..etc...and have him do a commentary as we go along...

I don't know why, but his mustache makes me want to trust him with my life.

Aaahahahahahahahaa whyyyyy😂😂😂

You love moustaches 😂

@Osama Boksmati BRO 💀

@Emily Guerrero vug

Thank you for this incredible insight that we ll never be able to prove or disprove. We ll take you at your word

Very good informative q n a session.

him: "warp speed is the invention of science fiction" area 51: "hold my raygun..."

How fascinating. Thank you.

Met him when he came to speak at my middle school, he answered all my dumb questions and was so kind. I didn’t appreciate meeting a man of his caliber at the time but I sure do now.

@Coffeeisnecessarynow whooptie doo🥳

@Repo lol its the only model that works

@Cory LeBlanc concave? lol 🤣

Lucky

space is such a trip, the fact it just goes on forever and doesnt technically have an end is one of those things that can really trip you out if you think about it too hard. like it doesnt end, ever

I'm fine with almost everything you said Commander, except for Space, because you were very high up in Earth's atmosphere still under its influence - not space. And the Sun's mechanism being a thermonuclear explosion, because the Sun is a luminary of calcium.

Imagine if we could hear the sun all the time!!

Question is it true if ship goes around the sun at high speed can you go back in time?

I could listen to him talk about space all day.

Itching ears.

Space ain't real bud. We are surrounded by water. And you want to know how? It's because God said so. 🙏 If you pray to God he will show you the truth 🙏 🙌

@Niall Decourcey No the bible, scriptures back up what is in it. Now I agree there is a lot of deception in religon. Get a KJV bible, translated fro the original texts. There is only one God . The Creator . As for these astro- nots, and " news" personalities,and actors they are mostly comedy for me.

@Langley Believer Just like how people will wake up about modern religions and start worshipping other gods, just like the religions before them, as they fade into myth.

@Science Revolution Amen, we dont live on a spinning ball either. People will wake up, some are too dumbed down though.

Thank you for making all of us as Canadians so proud of you Chris.

Im not.

Wow! That was entirely fascinating.

I could listen to him all day.

If only this man wouldve been my physics teacher in highschool

Chris seems like the perfect teacher. Imagine having him for your dad. Patient, calm, caring and most importantly...intelligent.

he seems like it? im pretty sure u can say he is.

I only hate lies.

I mean the dude is an ASTRONAUT… and intelligent is a requirement. Haters gonna hate… 🤷🏻‍♀️

@Thomas Payne Also actor, politician ( these things intermix well)

@Madlad iy

I'd love to have this man as my astronomy teacher. He seems so honest and kind!

This was so cool and informative. I don't feel like we are supposed to be in space tho. Just because you can do something doesn't mean you are supposed to. What damage is done to the o zone layer with every departure and return?

I got a question:if you where to go at the speed of light whould the gravity of everything around rip you appart or whould you feel nothing.

Yeah I figured instant asphyxiation outside of the suit in space. Even if you fry or freeze, it'll be over before you know it. And the steak smell I suspect you are correct. Sort of reminds me of Ontario Place when they first opened 😂 And energy - yes an immense speed is required just to GET to speed, likely a gravity force on an element, but maybe Musk's team is working on something, seeing that they have oodles of money (currently...no pun intended) at their disposal. So eloquently presented, thank you so much!
