  • So if it the radio waves look like what we expected to find, how do scientists know it was just interference? When will they know it wasn't interference?

  • I agree. 652 likes - 0 dislikes. That says something about the channel & its fan base.

  • Well on the bright side everyone that watchs this are your dedicated fans. (^-^)

  • Wow. 635 likes and 0 dislikes.

  • If the galaxies 72 billion lightyears away formed 72 billion years ago, wouldn't they be farther away from the center of the explosion of the big-bang because they were the first to be ejected?...and would the central point of the explosion form a universe sized blackhole?

  • @CriticuleMe

    Where did you get the idea the universe is 72 billion years old

  • @AtheistToothFairy I didn't state the age of the universe, just the distance/age of some the older galaxies and the time they were created...figuratively speaking.

    Honestly what I say holds no merit, I just know from a couple of Darnells videos that they referenced being able to see 72 billion lightyears with...the Hubble Telescope???

    Not too sure honestly.

  • @AtheistToothFairy I think he confused the size of the Universe with the age of the Universe.

  • Geez only 1 year? Seemed like a lot more to us. Happy anniversary space fans and Tony haha.

  • Great job over the past year Tony, I've enjoyed all your videos. Just for a laugh I watched Space Fan News #1 again... your videos are so much better after just one year. Looking forward to SFN 2012.

  • a happy informative year to all space-fans , courtesy santa darnell

    GO JWS

  • Maybe everything was closer together allowing black holes to consume more matter quickly. Everything is pretty spread out right now and takes billions of years for galaxies to collide.

  • Love your videos! But how do you know all this? Whats your work? :D

  • more years to come sir tony

  • I'm sorry for being a "noob" in this subject, But i was wondering if Black Holes can grow bigger with Dark matter?

  • @mse112233 They will still gain mass, which will increase their gravity thus creating more pull on other mass. I'm not sure if it would actually grow 'larger' in area or become more compact with DE.

  • @callmecoco sorry meant DM

  • This, Sir, deserves an instant thumbs up and to be fav'd. Every time.

  • Comment removed

  • Saw Black holes and time warps by Thorne on the shelf, great book!

  • Awesome! happy anniversary! keep up the good work just like downtown.

  • Only one year! It feels like I've been watching these videos for longer than that. Well done on these great informative videos you bring the most interesting parts of space news to your followers in a language we all understand and we thank you for it. Happy New Year and keep up the great work I'm looking forward to all the great stuff your going to bring us in 2012...

  • Great job! I've been following you for a while and really enjoy watching you channel. It's a great way to get caught up on all the relevant space news! Keep up the great job!

  • How is this the first video of tdarnell I've seen? subbed within the first 15 secs of viewing.

  • I remember Tony, I remember. The first Space Fan News. You were all like, this is the first Space Fan News n' stuff. It was awesome. Happy anniversary!

  • What a great video! You are a great educator. Keep up the good work! :)

  • Great video Darnell. Your videos are an awesome contribution to the people who love and wonder about space. The scripts you write are always very professional and as others have said, don't change your voice. It works very well for these videos and to be perfectly honest I think you would make a great narrator if you chose to make a career or money from it. Such massive black holes so early is very interesting. Keep up the excellent, thought-provoking work. We all appreciate what you're doing!

  • i think science is making a terrible assumption about time. time doesn't flow consistently. the universe may not be that age, it may be older b/c time could be flowing differently now for us, than it did then. We are measuring in light years, but we know light can travel slower in massive gravity fields, so who's to say that those 13.7 billion yrs to our perspective didn't take 2-3 times longer?

  • @montypython103

    That would be one huge gravity-field, and would be drawing things into it.

  • @montypython103 Agree

  • @montypython103 You mean to say that we could live longer if we lived in different gravity fields? lol

  • @CriticuleMe no because it would feel the same. when dealing with time dilusion as time slows down, you slow down wih it. you wont notice a thing.

  • @montypython103 You are hardly an authority to tell science what it can and can't do.

  • keep it up man you give hope to people like me that maybe one day we could leave this rock and get to see the real things in life, teach the masses how sweet space really is

  • @TlTSMGEE

    Heck, we could get to Mars TODAY in 54 hours at .5 G's.

  • thanks for all the videos. love them! 

  • I hope your shows never stop, I enjoy every show.

  • You can't imagine how important this is to allow the World to have access to that kind of Knowledge, thanks to you.

  • Tony, just as fclage2 I'm a bit confused over the size of the black holes you mention. Small black holes are perhaps a few km across, stellar class black holes are tens of km across and supermassive ones several AU, right? To me it appears that you're not quite consistent with mass or size. :)

  • I wonder, is there any indication of Hawking radiation in any of these early super massive black holes?

  • Congratulations sir on your year anniversary. It's been captivating watching your videos. Keep it up because they're so fascinating.

  • thank you for the heads up on video software. keep up the great work!

  • What is the name of the simulation you referenced? I would like to see some dedicated video to that, or just the name of it, maybe I could run it for myself?

  • @Albyint There's a link in the descrition box that describes it more, but this was run at a supercomputing center, I don't think you'll be able to run it unless you have access to something similar.

    The Carnegie Mellon link describes where it was done.

  • @tdarnell

    Sounds like you'd need Pixar to beat that.

  • Best channel on the tube!

  • Sorry, but @4:20 you say: "There are 2 main classes of black holes. There are stellar sized ones that are around 30 times larger than the sun"

    .... don't you mean 30 times "more massive" as the sun? or "larger than the mass of the sun" ? :)

  • Wonderful SFN once again Tony, as always! Looking forward to next week's videos on AAS!

  • No bloopers ?  :-)

  • I think its incredible the universe is so vast all them stars and galaxys, its just awesome

  • awesome vid

  • Thanks for a year of worthy news Tony !

  • The black hole things is confusing, you need colliding galaxies to create a super massive black holes, but galaxies are created by having a super massive black hole. Sounds like the chicken and egg thing to me. Only being going 1 year, wow it´s seems like you´ve been doing it for decades. Keep up the excellent work you are bringing important information to lots of people in an excellently explained way.

  • @bicnarok Well, think of it this way: massive stars in the early universe create black holes when they die. Over time, these black holes coalesce into larger and larger ones, eventually trapping stars in orbit around them. This is the very beginnings of a galaxy.

    Now, this is a poorly understood mechanism, so there's a lot to be figured out. This may also turn out be wrong, but it's the prevailing view right now.

  • @tdarnell

    Is this how galaxies form?

  • Hooray for almost 1 year, I appreciate all the work Tony, thank you.

  • I have the strangest boner right now

  • I'm unsubbing you.. in the mean time.. educate yourself with Alex Collier

  • @aaronCapricorn what does he have to do with anything?

  • I don't understand the rationale for the premise that black holes like to merge into larger black holes. They are geometrically tiny objects, just like stars, and we know that stars collide with a near zero probability when whole galaxies collide. I understand that very close orbits around very massive objects do decay but this has no relevance to this issue. So, can you please tell me what this black holes colliding idea is based upon. Thank you.

  • @heloizyjhenifer

    Geometric size only pertains to "flat" or 3-dimensional space, not hyperspace in which black holes are huge. Therefore to me, this indicates some type of Einstein-Rosen effect, where space becomes hypercurved to the point that it transcends the hyperlinear surface of flat or "normal" space.

    This would create a supermassive gravity-well, where any black hole in this area joins with the other black hole, but objects of lower density simply pass over unaffected.

  • @SovereignStatesman No offense but I need an answer preferably with numbers. I can imagine many things too, most of which will have no mathematical consistency or physical relevance.

    I want to know the probability of merging for black holes of a given mass falling at each other at the speeds of two galaxies colliding face on (in the order of a few hundreds of km/s). Then there's a minimum distance to find and it's probability. In any case, I need numbers and I'm able to verify them.

  • @heloizyjhenifer

    Offense taken, I doubt you can imagine much. since you can't seem to understand the basic qualitative issue that escape-velocity of black holes is obviously higher than lightspeed, rendering standard such factors void; however you're continuing to dote on distance in flat-space, while ignoring that you can't compare it to objects colliding in normal space by gravity alone.

    The distance could be infinite over time, rendering only a question of when.

  • if aliens were actually found, our idiotic government will just tell NASA to cover it up.

  • @vibol03

    Sure, just like the B-1 bomber.

    They couldn't keep a secret like that, which is proof that there aren't any.

  • This guy is THE NEXT CARL SAGAN!

  • I just discovered it but it's a must watch for me now! :) Keep up the good work!

  • I think we will realize within the next 100 years we DONT WANT TO BE FOUND.

  • @RimsterVision

    Speak for yourself, hermit.

  • God this puzzle has been tormenting us for years :( the universe is the ultimate paradox. Every answer turns up yet another mystery, it seems like the universe must ultimately be infinite, since we will always ask what is the cause of the latest solved mystery. But we know that can't be true, or can we. FUUUUU- >,<!!

    I'm worried that the answer to everything lies in a level of thinking beyond our monkey brains =(

  • @godly04

    Speak for yourself, monkey-brains. It's all math.

  • @SovereignStatesman

    lol, chances are I am much more intelligent than you are, I'm smart enough to realize we might not figure the universe out until we evolve.

    MONKEY BRAINS!

  • @godly04 "chances are I am much more intelligent than you are"

    You just proved you're not.

  • @SovereignStatesman

    lol just checked out your profile, explained a lot. Another failed lawyer who thinks he's smart, sigh.

    You're one of those =/

  • @godly04

    Failed? I've never lost a case. You just failed. 

  • @SovereignStatesman

    You've also never been a lawyer

    FAIL

  • @godly04

    You're right about that-- you fail.

  • @SovereignStatesman

    Also I giggled at how you talk to me as if you are somehow more enlightened than I am on the matter of the universe, when in fact you yourself have most likely made NO meaningful contribution to the study. You are just as much if not more in the dark as any average joe, yet you're passing it off like you're ahead of the curve. Enough fronting sir, I know what you are ^^

  • @godly04 "Also I giggled"

    Yeah, schoolgirls do that a lot.

  • tdarnell i hope you keep doing this , you may ask why? i will then say 'look at the like bar , that is why' , notice i calldd it like bar and not the like/dislike bar

  • I don't understand at all, why is there a duck on the book case?

  • @Delacresse

    Because the windowsill was dirty.

  • Thanks again for a great video, looking forward to the video's next week.

  • But what about the bloopers?

  • @AtheistToothFairy

    I hate those; missing a line is NOT a "blooper."

    Missing a step and falling out a window is a blooper.

  • @SovereignStatesman:" missing a line is NOT a "blooper.""

    I think one can extend the meaning of 'blooper' to include anything that was 'filmed' that wasn't intended, including messed up lines.

    Sorry that you hate those, but many of us enjoy them because I think we can relate to how difficult making such a video would be if we were doing it ourselves.

  • @AtheistToothFairy

    The point is that they're not funny, dumbass.

  • @SovereignStatesman:"The point is that they're not funny"

    Yeah, and that would be YOUR personal opinion, which is NOT held my many of his fan club, so STICK IT!

  • @AtheistToothFairy

    What did you take a poll?

    Speak for yourself you stupid moron.

  • @SovereignStatesman

    Take a hike, TROLL BOY!!!

  • @AtheistToothFairy

    Didn't think so, Sybill.

  • I really enjoy your channel! :D 

  • Wow, this is getting amazingly heavy. My, how things change quickly!!!!

  • keep 'em up!!! :D

  • Show us the duck-telephone!!

  • @helonic Check out the Nobel Prize Edition of SFN I did a couple of months ago. You'll even get to hear it quack.

  • @tdarnell This is one ugly duck - I`m loving it!

  • I just noticed Captain kirk in the background.....has that always been there lol.

  • @ravenheart93 No, I put it there a couple of weeks ago. Gotta mix it up.

  • i see your video 3 times, my english is bad, i don't undestand how there are big black hole so early....maybe for the solar wind that get off the falling gas?????

  • @eustachio79 Does the closed captioning help? I could slow down, but in order to keep these videos to a reasonable length, I need to talk fast.

    If there is a concensus, I could cover less information and do it slower. What do you think?

  • @tdarnell you arew lucky beacouse the 90% of the web site of this very interesting thing are in your mother lenguage.... if you give me the permission i could try to translate in Italian using my voice....some of your videos..... and the upload on my channel or send you by megaupload... what do you think????

  • your video are interesting, but you speak too fast, and my english is so bad :-(

  • @eustachio79 turn on the captions ;)

  • congrats on the one year anniversary!

  • thank you Tony yet another great video !

  • Yeah It would be great if you could comment on Russia´s Spectrum-R

  • @londonblock Good idea. I'll look into it. Next week I'll be busy with the AAS, but I like the idea, so I'll try to include it in the week after the meeting.

  • Your videos just keep getting better and better Tony! Thanks for this year!

  • HEY TONY! WHY DON,T YOU COMMENT ON THE JUST LAUNCHED RUSSIAN INFRARED TELESCOPE, I heard it will have a thousabd times more resolution than hubble, that is very exciting fot us spacefans

  • @StraussBR Will do. Probably after the AAS meeting.

  • @L00NGB00W, While stars that are larger than possible now could form, they were *only* about 300 (I think) times larger than the sun. This is because there weren't any heavy elements, which limit the size of the star.

  • I think that due to the fact that the universe in it's early stages was a uniform, opaque hydrogen nebula, There's a possibility that unimaginably massive stars (Millions of solar masses) could form. Much larger than what we're familiar with in the cold, condensed universe we know today.

    One uranium atom, and one hydrogen atom occupy similar volumes, But it took the fusion of roughly 238 primordial Hydrogen atoms to make it. There were many more atoms back then.

  • Super Massive black holes..... times a billion. 0_0 eep

  • Great video as allways Thanks!!

  • I'm always so happy seing you just uploaded a new video.Please keep these wonderfull videos coming!

  • If one of those SETI telescopes gets knocked out of allignment and ends up aimed at Tony's house, the terrestrial microwave readings will blow their minds. A voice resonating in a low octave...then a high octave...wait, back to low.....no right back to high....

    The Kepler team would think they discoverd a planet with aliens that go through puberty again in their mid 50s.

  • @frazzzer8888 i lol'd

  • @frazzzer8888 Heh, heh. Yeah, I guess my voice does go up and down. When I talk fast, my throat constricts. I'll work on it.

  • @tdarnell Don't change the way you talk. You don't want to sound monotonous and boring.

  • If anyone is interested in helping SETI then you can download a program called BOINC. You can download tasks which use your processor power to perform calculations and then send the results back to SETI. There are other groups involved in this and you can use your computer to help with cancer research among other things. Once again - BOINC.

  • this scares tha shit out of me

  • It's a long shot, but it's a well thought out long shot. It sounds like a good effort!

  • Happy New Year tdarnell and thank you very much for all your givings. Congratulations on completing a year of broadcasting. Awesome!

  • Thanks @tdarnell ! Your Space Fan News really gets to regular people who couldn't get to such informations for on themselfs. Keep up the great work!

  • Excellent episode, as always. Thank you for taking your time to do such videos. All the best!

  • Gratz Tony.

    If there were supermassive black holes at the dawn of the universe (< 1 billion years), then those are the earliest ancestors to the generations of black holes that emerge from the collision of galaxies. How many times can a galaxy collide with another in a 14 billion time span?

    Also, if the size of the early universe black holes is of the same magnitude as the biggest ones in our closest surroundings, then doesn't that clash with the homogeneity of the universe?

  • @gravedygger01 well you cant act funny all the time its getting borring

  • Thanks for sharing all those knowledge with us, it's greatly appreciated, I learn so much listening to your show, thank you.

  • Excellent Tony,Sadly we,in the UK don't get the same Pragmatic approach to Astronomy.

    We get a rather "Romantic" View from our Media and that is Few and far Between.

    The excellent "Sky at Night" gets scheduled on TV when everyone is in Bed asleep :(

    Keep up the GOOD WORK. The whole Family enjoy your points of view ;)

  • @DarkMatter1958 The Sky at Night is one of the best shows ever done on astronomy. I actually met Patrick Moore in the early 80's in Seattle. We were both attending a meeting and I was able to spend an entire afternoon with him sight seeing.

    He gave me a signed copy of his book 'Sky at Night 6', which i still have on my bookshelf.

  • Thank you Space Fan Master

  • You deserve more recognition, Tony. It's a shame; I hope you get that chance!

  • You are the best Tony.

  • no bloopers ? you must be getting too good at making the videos :)

  • @lucabaracuda987 I'm still screwing up but I figured I shouldn't do them every time. There are some who don't like them so I thought I'd give them a break.

    Besides, I used that time (30 seconds or so) to remind people about the AAS vids coming up next week.

  • yaahoo for tony!! yahooo for SCIENCE

  • Thanks for your vids man, they are really entertaining. as for my personal opinion the Big bag never happen... Until scientist broad their believe on this we would never understand anything.

  • indeed we know nothing, at least we can admit that xd

  • Thanks man

  • A video a day? that week will be one of the best weeks ever!

    Congrats on 1 year! Please dont stop!

  • Absolutely fascinating news / hypotheses about the earlier supermassive black holes!! Thank you so much for these videos Tony and happy birthday to SFN!!

  • Congrats Tony the first video I ever watched by you and got me to subscribe was The Hubble Deep Field.

  • thanks, you rock! keep em coming.

  • science take the wheel

  • thanks for the good video

  • thanks for the videos, always a great watch :)

  • cool =)

  • I am wondering about the simulations used. How do they decide what might be relevant or not? It seems to me that they can make assumptions about processes, look around the point to evidence of their theory. The 'evidence' might be the result of something really different. Who is to say?

  • @menthol5 Mathematics tells all.

  • @haiguizeify I have a degree in Biochemistry and have much experience with ideas that do not stand up to scrutiny. I am wondering about time scale. I wonder how we can make an assertion about events that take millions or billions of years to unfold when we have no way to observe these events. We look at something and it may be a result of our conclusions and then, again, it may not. Our ideas may be valid, but we have no way to know. The entire "dark matter," debate illustrates

  • Comment removed

  • @menthol5 I couldn't explain it accurately, but I assure you that what they're saying is accurate. Theories in physics are arguably the most scrutinized theories out there, mainly due to (like you said) the fact that we have no way to directly observe these events. The easiest way I can say it is there is much glory in mathematics. Although I'm unsure if it will provide much use, you can check out Physics Forums and ask around there. I'm sure you'll get a much more detailed explanation

  • Congrats on 1 year Tony. Keep the videos comin. All the best.

  • Comment removed

  • Keep the videos coming! They're great and informative.

  • Can a black hole grow the size of a galaxy

  • Informative and cool. Thanks!

  • i will tony

  • I glad you did these space fan vids. I have to admit I was slightly worried when these started but I feel you've done I fantastic job keeping us informed. Happy 1 year!

  • As per your comment on Facebook earlier about the positive comments on your videos- it's probably because you come off as genuine and your passion for astronomy and willingness to teach it is infectious and draws the viewer in, which in turn, garners HUGE respect. Keep 'em coming Tony!

  • @DougieBarclay I fully agree - this is great stuff :)

  • Ultra cool video Tony! This one really does 'ring in' the new year...lite pun.

  • WHAT?!?!?! Where are the outtakes? :D Great show, Tony!!! :)

  • Holy shit ? how's that even possible ?

    How can those early black holes be of similar size & mass as of today ???

    Doesn't that in-itself send out a message about this particular universe ?

  • Hello, space fan.

  • You ever hear reasonsdotorg? They share the same intrests as you but with possible ID.  Keep it up and Happy New Year.
