Space Fan News #52: The Doom of Early Galaxies; Remembering Fallen Explorers

[collado1981]

thumbs up for black hole book in the background

[SuperSpartan9000]

R.I.P. Fallen Astronauts. They truly show what it means to put your whole life into astronomy and astrophysics

[imguseulChoi]

i cant understand what you saying but i love your photos. Galaxy! Yeay!

[rccaulfield]

May gods richest blessings? Oh dear! Nice message cept for that - which god etc?

[chaotic1k]

RIP fallen heros. You will not be forgotten.

[aghoranathi]

I like your videos, have you talked about the controversial ideas of some of the astronauts statements about other life in the universe?

[toulouse666]

How to suddenly loose all credibility and rational usefulness in 3 seconds flat:

At 08:05 :

"May God's richest blessings... blablabla Religious indoctrination BS..."

Really?!?

An official ***NASA*** representative talking about GOD amongst all other insignificant moronic things?!?

I have now just lost the remaining shred of hope I still had for humanity...

[Cleaver428]

@toulouse666 haha remember just because its NASA doesn't mean its not in America!!! Land of religious retards if you haven't noticed all ready.

[Alec0124]

@toulouse666 Humanity needs to believe in gods if we have hope.

[bridaks]

@Alec0124 Humanity need not believe in a God like you mentioned friend. Humanity needs to believe in itself because in fact humans will never find "A GOD" to save them from their "Sins". No one will ever meet "A GOD". It will not happen today nor in a million years. We are much more than what we have been led to believe for in Fact, we are eternal spirits Incarnating to Evolve into an ever better Creation

Evolution of "spirit", spiritual growth to evolve. Until then it is ground hog day :) Love

[Alec0124]

@bridaks well I said 'gods' not a god. ;-)

And when I say we need to believe in gods I say nothing different than when you say we need to believe in ourselves.

I shouldn't use the word god but it seems to be the one that sparks most interest. What I meant is that perhaps it would be beneficial to embrace other people's views on the spirit.

There will always be the unknown, and thus there will always be perception.

Idk, didn't mean to ramble, but I believe we're in agreement on the subject.

[CriticuleMe]

If the big bang was really an explosion wouldn't that mean that the oldest galaxies would be farther away from the event horizon than closer?

[CriticuleMe]

@CriticuleMe This episode of Space Fan News reminds me of a PBS Special with Dr. Greene.

[DeadMemories03]

Nice video Tony, I'm 16 and I kid you not you have inspired me more than any other person I've ever met or listened to, so thank you. Hey in 2 hours it'll have been 41 years since apollo 14 set off =)

[Man4From2Mars]

ENDING!?! WTF!?!?! (okay okay calm dawn calm dawn.)()()()()()((( next week comes new video and then you see tonys fail moments½ ou jea)

[Riggro]

If you ask me, I'd say there's no better way to lose one's life than losing it in the pursuit of discovery and exploration!

[SomedaysDreamersBC]

got around half way through when I realized i watched this already.... and then i kept watching anyway..................

[glenwoofit]

A fitting tribute. Sometimes when we reach for the stars we get there a little too quickly. RIP all who have died taking man out into the cosmos.

[Destro7000]

D'you think we know stuff about those Elliptical Galaxies now that some of the inhabitants don't know themselves?

[michaelcurry2000]

Must be great to have his brains

[jgwoodworking]

You know, It is hard to describe how proud I am of our astronauts and those scientist. they are people I wish we would put more money into... Too infinity and beyond!!!! yay

[billp1955]

R.I.P. TRUE AMERICAN HEROS!

[billp1955]

4:10 is a "that makes sense face". I know, because I made the same face! hahaha

[cmelan]

you make money out of this? gooood. because you deserve it; you will be first person I'll actually follow on youtube.

[blazak]

I was 5 when Apollo 11/Eagle landed and it still feels like yesterday. So, what do you think of Moon Base Newt?

[Mrmannyguy]

Another great video.

[xXDEICIDE216Xx]

Rated, commented and favorited. Thank you Mr Darnell! :)

[ImmaGoners]

It makes my stomach turn. Thinking that there are human bodies, floating forever through the depths of space..

[blazak]

@ImmaGoners There aren't. All died in Earth's atmosphere.

[ImmaGoners]

@blazak How do you know that? The US government could just be lying to you. Cosmonauts died in Space too.

[blazak]

@ImmaGoners ???? Apollo 1, Challenger, and Columbia were not is space when the accidents happened. If someone else went up and didn't come down, don't you think it would be a story? Maybe they're with the aliens in Roswell!

[ImmaGoners]

@blazak I'm saying there are probably many missions you never knew about. That failed.

[Hooya2]

@ImmaGoners Like NASA has the budget to run secret missions lol. It doesn't even have the money to keep many of it's public missions running.

[dmfalk]

If there was ever an old man who turned into a child, it was with Cronkite when it came to the space program. Even after his retirement from CBS, up until his death a few years ago, he would be asked to participate in any broadcast having to do with space. He became our voice for our passion for space. He earned that moon rock- The only civilian to be given one by NASA.

Tony, you're the closest we have today to a Walter Cronkite, so on behalf of all of us--

Keep looking up!

d.m.f.

[chimemonster]

could have avoided the human interest angle.

very interesting that the first generation stars are so easily formed , means 2-3rd gen stars with high metallicity existed possibly at least 9 billion years ago ?

what would a being look like with 9 BILLION YEARS of evolution!

scary.

[johnmantra1]

Great video! Very moving too!

[breakaleg10]

I find myself automatically pressing the "like" button every time Space Fan News begins. This seldom happens anywhere else on Youtube. I guess it's because of the way you present the facts, Tony.

[funkyharry5]

Hey . Did u know that dark matter is just  a bluff fore as !!!! Look some dok. films abou that.

!!!!!!!!

[talkingprimate]

He had me until 8:06. There is no god... Surprising the NASA guy would say that...

[1GTX1]

@talkingprimate lol

[TORREY333]

Safety is IMPORTANT, but it should NOT be our guiding light! Instead, we should EMBRACE the ADVENTUROUS SPIRIT of those who sacrificed their lives for a flourishing Humanity…

[esamiga]

Thank you Tony. We remember all of them!!

[detersgumig]

Ah those memories. I'll never forget when my parents pulled us kids out of bed in the middle of the night to watch TV that day in 1969 when Apollo 11 landed on the moon ...

[Cocoshunt]

Lookin well for 49 T!

[thedirtywhitesock]

You look like Gordon Freeman from half life 2.

[AkiGavriloRadovic]

don't be afraid to speak out to authority okay hes reading that not meaning it and mans never been on the moon in 1969 there said it

[bicnarok]

@AkiGavriloRadovic man has never been past the Van Allen belts imo, and I wonder how they got the mirror on the moon:)

[bygota]

They're true heroes.

[huyked]

Thank you astronauts, cosmonauts, NASA, and fellow space fans for furthering the knowledge, and the spirit of discovery.

[tantaweens]

When you wish upon a star , is someone looking back and wishing upon our star , our sun ? I for one belive this is so . Great work Tony .

[fangjian]

Thanks for sharing ur experience of Apollo 1. I was 6, watching the Challenger live on TV. I think about them often as well.

[makkathran]

If the sun vanished instantly, would the Earth immediately start traveling on the tangent of it's Solar orbit, or would it take longer (for example; light takes 8 minutes to travel from the Sun to Earth)? In other words, are gravitational effects felt instantly across any distance, or does it behave like light in the sense that is has a certain speed?

[fangjian]

@makkathran It would take 8 mins for the Earth to leave it's orbit.

[makkathran]

@fangjian Thanks for the clarification.

[TekLok]

@makkathran Yeah its crazy right? Gravity takes about the speed of light to be felt. I heard it recently too.

[makkathran]

@TekLok That is crazy. I mean, I can understand light being a photon, with a speed... but, gravity is a pulling force! Weird, but very cool! Thanks.

[TheHemsworthboy]

@makkathran If the sun did disappear, it would be quite difficult to think what would happen, the inner planets might be caught in Jupiter's gravity well and started orbiting it, either way we would freeze to death, but the planets will carry on orbiting the galactic center.

[makkathran]

@TheHemsworthboy It's quite interesting to think about :)

[justindrummm]

@makkathran

The sun would continue orbiting the sun as if were still there for exactly the amount of time it would take for light from the sun to reach earth. Sounds crazy, but if the sun were to suddenly vanish, earth would be orbiting nothing for about 8 minutes. To us here on earth, the planet would veer off it's path as soon as we see the sun disappear.

[justindrummm]

@justindrummm

Oops, I mean earth would be orbiting the sun in that first sentence...

[makkathran]

@justindrummm That would be extremely frightening!

[Cleaver428]

@makkathran if the sun vanished it would emit gravitational waves that move at exactly the speed of light. once these waves reach earth it is then that the earth would lose its orbit about the sun, but until then, it will remain in a stable orbit.

[DJSchousen]

@makkathran It goes at the same speed due to properties of our universe.

[ItsNotEvenSunny]

@makkathran Gravity travels at the speed of light, Stephen Hawking said so. So as soon as we noticed the sun disappearing, so would gravity.

[MyPhysics101]

@ItsNotEvenSunny

"Stephen Hawking said so".

Lol

[ItsNotEvenSunny]

@MyPhysics101 Hahaha i know right, i didn't quite know how to put emphasis on it to make it not seem so "He said so so it must be true" -ish. But w/e lol

[MelkorHimself]

@makkathran Since Einstein proved that nothing can travel faster than light, the ripple in the gravitational field would take over eight minutes to affect us, so Earth would maintain its orbit until that time.

[Debbie321lopez]

High this if you are like!

[paimail21]

Am I the only one who accidentally mix this guy up with Kurt? you know, the minecraft guy?

:S

[Bryantozero]

@paimail21

If anyone, he looks like Gordon Freeman!

When i see that Tony has a new video up, my mind responds with "Oh nice, it's the Freeman!".

[spanod]

Great show.  Information is timely and delivery is well done. The sound quality doesn't do it justice. I am a fan nonetheless.

[351xb1973]

A question regarding dark matter, As dark matter doesn't interact with normal matter would blake holes have any affect on it? Nice tribute to the lost astronauts. I'm sure there's been a few support staff lost over the years too.

[Dextomus]

@351xb1973 Well... As far as i understand dark matter still reacts to gravity so in that case yes.

[Urglab]

@PompousPreacher Firefox + Adblock Plus and you'll never see ads again.

[PompousPreacher]

@Urglab But if you don't know what the sinister ads are about, you'll just be gay and merry and watch Justin Bieber and the Brady Bunch and be entirely divorced from reality!!!!!!!!!

[Bryantozero]

@Urglab

When you open a link in fullscreen and an ad starts rolling, change the window size to small and it'll skip the ad. (works for me on Chrome)

[tdarnell]

@PompousPreacher I just wanted to say that I don't have any say in what ads appear here. This video is the first one I've noticed where they are displaying this style of ad. Usually it's the banner ad on the right with a small ad along the bottom.

My apologies...

[nmryda]

@PompousPreacher Adblock Plus. Google it, install it, and Drake me (thank me later)

[leptonsoup337]

The first memory I have of space exploration was the Challenger disaster when I was just a little bit older than two. I did not understand really what was going on but I remember the solemn atmosphere. Over the following months and years I would always ask questions about this event, learning more about science as I went along. Challenger really helped cement my interest in science and has served to remind me that exploration is a dangerous undertaking.

[sappha58]

To your final comment: me too. Me, too. *sigh*

[alienfast]

R.I.P. to those fallen. It's only through them that we can further what we know.

[SamsusAlleria]

Tony, I can only hope that you inspire just one more individual, as those early explorers had inspired you, as much as you've inspired me.

[tdarnell]

@SamsusAlleria Wow, thank you. You humble me.

[bignorge]

@SamsusAlleria DITTO THAT!

[sirkyan]

At about 6:30 "in the service of our nation" should be in the service for mankind. Their work is truly that of someone breaking the walls of a box in which someone lives, opening up the vast beyond.

The reason for living!

[tdarnell]

@sirkyan I agree completely. The U.S. isn't the only country that benefits from exploration. Nor are we the only ones to grieve when someone engaged in that endeavour is lost.

[Kariakas]

Thanks Tony.

[ThriveOnKilling]

My right ear enjoyed this, however my left one is now lonely.

[tdarnell]

@ThriveOnKilling My apologies. I think I finally figured out the problem. My new camcorder had a mic that was set to surround and I was creating a final cut project with 2 ch stereo. I think that screwed up the left channel and made it lower than the right. Hopefully the next video will be better. Thanks for your patience while I get used to my new camera!

[NickDrake101]

I know what you mean about Cronkite, Tony...and the Moon...I watched it all unfold in my living room on an old Quasar B&W and at the the same time peeking at the Moon through the living room window..now those were real memories.

[lucabaracuda987]

Tony how do you do it man? You upload a video every Saturday (here in Sydney) after i woke (around 5-6pm here - me working night shifts), after i take a shower and i grab a cold beer.

You're like a Swiss watch heh.

[kashivranik]

Seriously you need more views :|

[lolingattheism]

Have to say this: there is something profoundly wron, when NASA guy has to invoke gods blessings...

[HaloZero147]

@lolingattheism God got sick of playing hide and seek.

[InnSewerAnts]

@lolingattheism Why? Science doesn't deal with any religious question, they are not mutually exclusive? Science doesn't preclude creation, it precludes certain detailed but baseless idea's about how it was done which are part of what we call religions. The general idea of creation or god(s) of some sort is not something that can be proven or dis-proven with science, it's a mute subject. If there was a creator or not really doesn't effect science, it doesn't change e=mc^2 etc.

[xXCrimsonVirtueXx]

Tony, why not do a video about the solar cycle being at it's highest point? Or the (almost) x-class flare that's hitting us at this moment? Peace, brother.

----------------

-RON PAUL REVOLUTION.

[AtheistToothFairy]

I was often told that the capsule fire was indeed caused by a spark, but that spark in the pure O2 environment ignited VELCRO, which was quite flammable.

Do you know is that is a true story?

[ferrett78]

@AtheistToothFairy Pretty much. The wikipedia entry has quite a lot of detail

[jcbwalters]

Thank you for this edition, esp. the memorial, very important to always remember.

[Odashiman]

Let's also remember the Challenger disaster, and the life of Christa McAuliffe. She is the reason why I wanted to become a teacher. I still want to be the "first teacher in space."

[Melee2Kil]

@Odashiman What do you teach?

[Odashiman]

@Melee2Kil Let's not misunderestimate each other... I'm still an undergrad, and I expect to graduate this December with a BS in History. I will have a Social Studies teaching license for grades 7-12. My goal is to work for the Department of Defense Education Activity, because after serving in the military for 13 years, I want to continue to support our troops by teaching military family members.

[Melee2Kil]

@Odashiman Thats awesome, good luck.

[TheArthas17]

interesting 

[eruption323]

R.I.P fellow astronauts. . . Their work will never go unseen in the progression of man kind.

[Lukeschedel]

@eruption323 You mean in the progression of space exploration.

[eruption323]

@Lukeschedel That too, but in reality earth will not be around here forever. We will have to move out of earth or face extinction. Which will destroy man kind.

[est000dog]

@eruption323 but spationauts, taikonauts and astronauts?

[xTSxALLDAY]

I like first THEN I watch

[filthyfun]

cheers mate

[irishmonkey640]

First. Great video as always
