Space Fan News #43: Kepler-22b; Biggest Black Holes EVER!; Swift Sees a Strange GRB

[dornkrull22]

love all the video's--good job taking the time to put the facts in common speak

[hollandiskampioen023]

dont get it really good buts still interesting

[crivez82]

No picture of black hole exsist. NO ONE. By now, is still impossible take a image of one. This video is for nooooobs

[lilsadi80]

Oh my goodness, marry me! Seriously, I so completely enjoy your videos, the humor you infuse, and your love for science is infectious! Keep up the wonderful videos.

[Area51Phantom19]

Its so interesting... what makes this a controversy to religion is that many ppl believe that god created earth...while scientist researched that it was to be a big bang theory that created the stars and solar systems. Also that planets were created from a forming ball of gases.

[mnpell02]

These videos are incredible! I'm in the process of watching all of them in one go! I just can't stop... So much info.. Keep up the good work!

[leon920419]

This is so DAMN INTERESTING! gotta love tony! :)

[chestypants78]

I love that face you make at 3:03 (tries to comprehend a black hole 2,000 times bigger than the one at the centre of our galaxy). The huge figures, vast distances of space do that to a man.

[maplestory352]

bad thing in space is

-black hole

-big bang

-meteor strike

-too cold

-other

[zark212]

@maplestory352 7 Justin Biber cd playing on repeat.



[qwas12348gr5]

Could you put up subtitles, please?

[fedscry]

whould be nice to add subtitles in each video..it would help people who doesn't speak english perfectly like me..please add!

[lastplacewin]

Tony, your easy to follow/understand videos over the years have inspired me to buy a telescope and start reading and teaching myself more about our solar system, and indeed the universe.

Thankyou so much, and I will keep looking up!

[kpvids2]

what if our entire universe was just inside one black whole and there are black wholes inside black wholes? :)

[Brodes1983]

Thank you for highlighting the pathetic term "Christmas Burst" >:-/

[bicnarok]

maybe there are no more black holes, considering the time it takes for the light to get here they might have only existed at the beginning of the universe. And the centre of our and other galaxies might be angels not black holes:) (joking)

[crespo1983slb]

our universe, is a black hole in another universe

[lolzman7]

@crespo1983slb But in soviet russia, another universe is in a black hole.

[crazybadcuber]

space is so weird and huge that it makes it scarier than shit!

[Area51Phantom19]

@crazybadcuber

It makes people go nutz....

[MrAwesomesauce101]

@MariaAng3l3s Black holes have infinite mass and rip apart anything in there path. Nothing can escape the gravitational pull even light.

[SyLaRSaGe]

well hopefully the gravity wouldn't crush us haha and traveling through space would cause our phones to soften up

[BigMTBrain]

tdarnell... the MAN! What a true delight it is whenever I see that tdarnell has new videos. Not just for the information content, but for the refreshing personality and approach to sharing interesting and most often exciting information.

[MariaAng3l3s]

is black holes bad???

[SyLaRSaGe]

@MariaAng3l3s Won't hit one in a really really long time

[lastplacewin]

@MariaAng3l3s

Not unless you want to turn into spaghetti ;)

[stamstuff]

cool video!! its something like someone from the year 1400 have started a quest in the speed of light and after 600 years the goal has been made by his garnd, garnd, garnd, garnd, garnd, garnd, garnd, garnd, garnd, garnd, garnd, garnd, garnd, garnd, garnd, garnd, garnd, garnd, garnd, garnd children... none of us will be here... Gliese 667 C sounds more practicle to get, only 20 LY away, and still, too far for now, and with this monatery system, it sounds that we are closer to WW3.

[MrGOTAMA420]

@stamstuff 20 ly or 200 it doesnt mean a thing by the time we get there we will be folding space or making wormholes to get there so distances wont mean much

[stamstuff]

@MrGOTAMA420 maybe we already did, and you just dont know it...

[MrGOTAMA420]

@stamstuff or mabie we didnt and it hasnt happened for us yet?

[stamstuff]

@MrGOTAMA420 mabie .... just mabie....

[crespo1983slb]

@MrGOTAMA420 assuming...biological beings can survive a whormhole crossing. yeh, it's theoreticly possible to open them...but don't forget that life, at an universal scale, is very fragile.

[MrGOTAMA420]

@crespo1983slb fer shure

[MrRedJax]

I think Im going to sound stupid but can black holes disappear?

[MrGOTAMA420]

@MrRedJax i was wondering if they ever get full?

[Evertonian94]

I really hope JWST launches! My dream is to become an astronomer by it's launch. In 5 years? :)

[LemmingdeMerciless]

brilliant as always Thanks Mr D

[dekmaskin]

1) Pause at 0:00.

2) Press left and down arrow.

3) Have fun!

Also, thanks for yet another amazing video!

[beetlerom]

Great work Tony! I really appreciate you taking the time in making these videos!

[rocketmagnet]

@420in757 Now there are only 302 views !

[Miguelc271086]

So if we had a telescope about 2 million light years AWAY from earth. We could see how earth was like two million years ago.

[subh1]

@Miguelc271086 That's where Einstein forbids travelling faster than light. If you could reach 2 million light years away even at the speed of light, you will end up seeing the Earth as it is today.

[Miguelc271086]

@subh1 What if we could travel faster than the speed of light? To me, there is the slight chance that traveling faster than the speed of light does not mean going back in time. It might just mean moving faster than a photon. Much like traveling faster than the speed of sound.

[subh1]

@Miguelc271086 Theory of relativity shows that speed of light has some special context in how our universe works (unlike sound). One consequence is tht time is relative: 2 events that appear to happen 1s apart to someone, may appear to happen 2s apart for someone else moving at a different speed (close to c for being perceivable). However, the order in which they happen is never reverted - that's causality. But, if one can travel faster than light, causality is broken - besides other problems.

[marylipstick]

Nice video's man... nice teacher you!!! Keep up the good work, sad you no have more viewers, but nice videos!!!

[Tarlev]

I bet you drive Kia ;)

[Villymayn]

I feel like such a nerd watching this...but it's so darn interesting!

[megamarsvin]

@Villymayn You say that like it's a bad thing :D

[Area51Phantom19]

@Villymayn I agree only if this was more like a space channel instead of some dude hiding under his basement

[fixitluis]

if i may ask since the larger the planet, the more gravity it has, isnt that one thing that might make it unable to live in?

[Heli0Jr]

@fixitluis not necessarily, life would adapt to the stronger gravity. Although, due to the thicker atmospheres, I think the greenhouse effect could make the planet too hot for life to evolve in the first place...

[nerox2006x]

I just have a bad feeling about the JWST, it's such a complex telescope I just have a feeling something is going to go wrong....

[letzsee9]

What will happen if things get absorbed into a black hole?

[PorscheNine18]

@letzsee9 Thing will go to atoms? Am I right?

[bogdanov0001]

Great videos Tony! Thanks!

[spanod]

Interesting information, presented in an entertaining way. Definitely one of your better updates. Thanks.

[DireStraitsInImpala]

Space... you scary.

[Pikers81]

8:00 Mission 28. Ok gamma ray burst, GO!!

[Neueregel]

That Black Hole of 10 billion solar masses ~ 10^44 g is quite heavy indeed. She should be on a diet ASAP

[xdassinx]

What would a gamma ray burst be called that landed on Larry Flynt's birthday be called?

[Neueregel]

@xdassinx no

[toulouse666]

As always, Thank you for making these awesome videos and keep looking up! 8)

And BTW, you don't need to show outtakes to appear cool, anyone that doesn't get how infinitely cool cosmology/astronomy is doesn't deserve to exist, period.

[CriticuleMe]

Are GRBs visible to the naked eye?...because I think I've seen 2 in the night sky in the past year.

[Cleuskywalker]

Ten BILLION Solar masses oO Omg I played again this moment repeatedly it gave me so violent shivers

[xXDEICIDE216Xx]

POST MOAR VIDEOS. NAO!

[SRDTL]

I have a (possibly) silly question; i wondered while a star explodes, how fast does the exploding matter move? i mean, behind all the power that is pushing it away, could it travel faster than light?

[Lynchpinn101]

lol...love the outtakes....and as always the info...thanks my friend :)

[yaxpak1]

I have a problem with the whole "black hole" theory. To me they seem more of a creative, corner stone, foundation, order keeping objects in the center of galaxies rather than these destructive dragons scientists have proposed. I think Einstein got it wrong. I am no scientist, but love astronomy and I have always viewed black holes as rather these whirlpools of energy that spew out matter derived from concentrated atomic energy in the center. "black holes" are life, not destruction.

[bboschboi]

fuck i could have ha a perfect view of the lunar eclipse this morning, but i didnt get up :(

[Danny77uk]

Duck Phone!!!

[tonyzwlu]

Tony your videos are very GOOD; Could you please let us know something about kleper-22b? The planet is closer to its hosting star, we understand the hosting star is cooler than our hosting star, but it still makes lots of UV rays and bcoz the planet is closer to the hosting star that would make harder for life, another thing is the country is massive, any kind of life will be attached to its surface, winds are faster than here because there would be higher hills like earth, so how can life be?

[ahg337]

@tonyzwlu Well even if the planet is getting hit with solar rays, 22b could have a magnetosphere similar or even stronger than ours since it's like 2.4 times the size of Earth. Gravity would be stronger but not so strong that it's crushing living things against the surface... life can be quite surprising, don't underestimate evolution

[noodlerII]

schmommon envelope of schmash



[synethmail]

Gordon Freeman?!

[ktmfr3ak]

nice one :)

[prestonscott73]

wow, the goldilocks planet is the least crazy of these three topics- the universe is awesome!

[PiskieBenWa]

Love this channel! ... outtakes & all : )

[TheHunnyhillbees]

Brilliant - thanks!

[YamiAkimotoMayu]

:'D Thank you once again for such a brilliant video. You've honestly got me hooked - I owe my obsession entirely to you.

After watching your videos I generally pause it on a still with you and the background of your brilliant library - I'm wondering if there are any books on display that you would definitely recommend to someone interested in astronomy, cosmology, physics, astrophysics, and the like?

Thanks again. =D

[Mocib]

There's also news about a black hole with the mass of 21 billion suns (NGC 4889 galaxy).

[tdarnell]

@Mocib NGC 4889 is one of the galaxies I discussed here, and the figure is closer to 10 billion (at least according to the Gemini folks. I saw that number too in relation to this story but I think the reporters got confused and added both black holes together. Even the NY Times got it wrong in their story.

[Imamar2]

You said what holes? :P Good vid! You even have 1 book about black holes in your "library" behind ya ;)

[dillinger9999]

Alright who disliked this video 3 times?

[dillinger9999]

Your Videos are amazing as always. The first video that hooked me, was The Hubble Deep Field: The Most Important Image Ever Taken... I have watched that more than 10 times already...

[solidarnagrupa]

Have you read all these books behind

[tdarnell]

@solidarnagrupa Most, but not all. Sadly I don't have much time for reading these days.

[Kriegfreak]

Awesome as always ty

[bappo456]

TY Tony

[OTUFilms]

You're using the bookshelf again :D

[synethmail]

Gordon Freeman?

[eruption323]

Are you an astronomer? 

[KimiScuderiaFerrari]

@eruption323 yes he is.

[tdarnell]

@eruption323 I'm an astronomy software engineer, and I do astronomy research. But that's not my job title.

[martixbg]

@tdarnell What does that actually mean - astronomy software engineer?

My interpretation would be someone who comes up with computational models that simulate the universe on a cosmological scale. That right or am I missing something?

[vibol03]

but Leo constellation doesnt rise at this time of the year :(

[doe791]

Those super massive black holes are relatively very close to us (only a few million light years away).

Makes you wonder how big the ones that existed when the Universe was a lot denser were - or do you need billions of years of accretion to get the biggest ones?

[artbasss]

Mr.Darnell,could you please cover the recent controversial video of solar plasma hitting Mercury and producing some strange huge flare in its vicinity. What could it be in your view?

[tdarnell]

@artbasss No. I did a post on the Space Fan facebook page pointing to the explanation of what that was. It was an artifact from the image processing, not a cloaked starship. My view is that UFO buffs should understand how astronomy images are processed before jumping to conclusions in scientific data. It was a classic case of not understanding the data they were looking at before drawing conclusions.

[artbasss]

@tdarnell Thanx. Now I'm your FB follower also. Keep looking up)

[sidoney101]

Great post as always! Question: when (if) JWST is operating how will it get past the problem of star glare to be able to resolve the exoplanets?

[tdarnell]

@sidoney101 There will be occulters on the NIRCam instrument that block out the star.

[sidoney101]

@tdarnell Thanks for your answer. Keep up the good work.

[LKRaider]

Would it be theoretically possible to "undo" a black hole? That is, to retrieve all energy it consumed?

[tdarnell]

@LKRaider I don't know, sounds intriguing though.

[ZaDominator]

@tdarnell well let's say you can how much energy are we expecting :D, and .. is'nt a black hole a emitting a gravitational force ?

[ApatheticOmniscience]

@LKRaider I'm not sure but, I think Hawking Radiation is like "undoing" a black hole.

When a particle-antiparticle pair pops into existence, the particle with negative mass might be behind the event horizon. The negative mass particle falls in decreasing the BH's mass while the positive counterpart flies off to be observed as radiation. After a while, the BH should shrink and eventually explode if no more matter is introduced. So, black holes "ain't so black"; they emit radiation all the time.

[jdragon1012]

@LKRaider yes theoretically. whatever it suck in get printed onto it much like information on a microchip. you can theoretically retieve it.

[chongma]

@LKRaider hawking radiation

[TheDivineWinds]

@LKRaider

Quick, patent the idea!

[MarkArandjus]

Awwww yeah, JWST gon' give it to ya!

[isjackal]

There are also strong suspicions concerning "mini" black holes (between 1 and 100 millionth of billionth of a meter for 1 to 100 billion tons, dating from Big Bang if not pre-Big Bang) and "micro" black holes (hundredth of a millionth of a billionth of a billionth of a billionth of a meter... for a few grams, and resulting from collisions of particles), even if their existence hasn't been proven conclusively yet.

[elpablonicolas]

The final cuts at the end made me crack, thank you so much as always

[morog666]

awesome video. but when you speak about this HUGE numbers, could you please scale down the sizes(maybe be doing some comparison) in order to us understand, as much as possible, the true meaning of that information. Thanks and of course good job :)

[tangent123456]

I've read about these 2 Supermassive black holes, it's quite an amazing discovery ! But, isn't the Supermassive black hole OJ 287 much more superior ? =/ ... It has an estimate size of 18 billion solar masses..

[otur1]

"Thank you for watching" No, Thank YOU for informing / making videos!

[cjw1010]

theres one thing im confused about if the super black hole was 10 billion solar masses how massive was the star it came from? Im pretty sure that black holes come from when giant stars collapse on themselves, but im not sure if theres another way.

[Ridleysama]

@cjw1010 Super massive black holes do not have the same origin as interstellar black holes, which come the collapse of high mass stars. Super massive black holes may have formed from gigantic gas clouds that eventually became galaxies with the black hole as the center. Both the black hole and the galaxy grow bigger by devouring other galaxies and its black hole, causing a merger.

[doe791]

@cjw1010 Black holes can be fed by matter funneling down into it thus increasing its radius and mass. The ones at the center of galaxies form the galactic nucleus and are central to the evolution of the galaxy. If the galaxy is young, or if it collided with another galaxy, the nucleus starts to feed and the galaxy is called active. If enough matter if funneling into it, the surroundings of the black holes can become very luminous and form a Quasar.

[stramster1]

I'm a bit cranky because cloud ruined my observation of the lunar eclipse so I'm here instead.

Great video ty. I have a question regarding Quasars. Is it possible for colliding galaxies to trigger Quasar like activity as material is consumed and the super-massive black holes merge and if so has this been observed and at what distances.

Anyone with a link or a reference would be much loved.

[tdarnell]

@stramster1 Absolutely, in fact its one of the signatures of a galaxy collision. Along with rapid star formation.

[stramster1]

@tdarnell Great thanks for that. It would be reasonable then to find such quasars randomly distributed through space at distances much less than the quasars formed from young galaxies. They would be irregular and contain population 2 and 3 stars. Do you know if these observations been made? I am interested to know what distances and distribution these are seen at.

[ticrisse]

Hurray for the Christmas burst!!

[FreeStyleProjector]

@Cheese71 i wouldn't say it's possible, it is definitely completely different from here on Earth ! for example the closest Mars has ever been to Earth is 56 million km, with diameter of 6790 km (Earth 12750 km) or about half the size of Earth, One solar day on Mars is 24h 39m (23h 56m for Earth) 1 year is 689 days to 365 days for Earth so yeah !

[TheHemsworthboy]

i used to look at galaxys until i took a gamma ray burst in the knee...

[goreziad]

thank you for making these videos :)

[SeltsamerAttraktor]

So what are the other 811 reasons for JWST then? ;)

[shezie125]

Love the outtakes!

[MrBigInfidel]

Maybe Jesus lives on Kepler22b, so we just need to pray and ask him how the weather is where he is at.

[gigacoasterfan]

Do a video on what would happen if two black holes collided.

[BasicSpace42]

@gigacoasterfan Not much, they would simply merge.

[defect530]

I'm watching this and a lunar eclipse at the same time.

[KimiScuderiaFerrari]

If even the light can't escape from a blackhole, then what is that beam at 3:21?

Love your videos! Especially the endig of them:D

[Cycloheximid]

@KimiScuderiaFerrari These beams are gasjets. The matter in these discs is still magnetic and induces a strong magnetic field around those holes. when matter falls on the event horizon some of it gets deflected along those field lines to the poles. Out of this matter plasma gets ejected at almost light speed. only black holes with spin opposite to its accretion disc are suspected to have gasjets.

[KimiScuderiaFerrari]

@Cycloheximid cool thanks

[L00NGB00W]

@KimiScuderiaFerrari The 'beams' emitted from black holes consist of material that never actually crossed the event horizon. Basically they had the wrong trajectory to fall in. Kind of like a slingshot effect. Although I'm sure there is some much more complicated physics going on there.

[Ridleysama]

@KimiScuderiaFerrari That is stuff a black hole fails to 'eat' and is ejected via that Black Hole's Magnetic poles. They are called jets.

[GaoAsaurusG]

Do we really know how far away it is? If the results of the experiment *cough* and the repeated experiment that showed particles traveling FASTER than the speed of light is proven true by other researchers...we are going to have to rethink ALOT of the assumtions we have made using calculations that assume that light can Not travel faster than light.

[TheBenjaminVrenko]

"Get your scope out and check out the black hole" hmm... sounds funny xD

[tdarnell]

@TheBenjaminVrenko Well, I meant the elliptical galaxies they live in.

[TheBenjaminVrenko]

@tdarnell I know I know, I'm just kidding :D nice videos by the way, I watched every single of them! Great work!

[dudynipple]

i love your videos

[maggru91]

Keep up the good work :)

[SuperLaugh20]

yay, the books are back :PP

[MindLessWiz]

Lotta love Tony!

I enjoy these enormously.

And I died at the Christmas Burst face you made. That was so unexpected, LOL.

[MyWorldView]

Can a black hole be destroyed?

[Debbie321lopez]

It looked like a black hole sucked all your air out of your body @ 2:14

[Rumplefrumple]

thanks for the free infotainment!

[WatchmenDrManhattan]

I wonder can you use a black hole of that size fore gravitational lensing & what would be the results

[test123ok]

awesome ! thank you for the post

10 billion solar masses -> 1.98 × 10^40 kilograms

Wow... i cannot picture that kind of mass ....

... unless I think of Yo Mamma

[chrissh85uk]

@test123ok lol

[BassCausality]

@test123ok I read this as Yo Yo Ma, which I was initially very confused at.

[white9257]

THANK YOU for the bloopers at the end! A real treat on top of wonderfully presented and fascinating information! I'm hooked, so keep the fix coming! :)

[HCLivess]

You are so cool man!

[laurence265]

JWST FTW!

[stayhomel]

haha, 'the Christmas burst'

[SamsusAlleria]

3:41..so my Avatar/Pic w/e It's called on youtube.

[Delacresse]

The editing is annoying. The best way to avoid this is to have a script, or include your errors. It's okay to slip we all do, it let's know you're human T.D.

[tdarnell]

@Delacresse The funny thing is, I do have a script. I used to do it that way, but it was just too hard. Many long time viewers can tell you, I struggled with that for a long time. For an idea of what everyone has suffered with to get this far, check out my earlier videos. Some are actually quite painful to watch! ;-)

Anyway, I'll be more careful.

[tdarnell]

@tdarnell I meant, I used to do it the way you suggest (all in one take and show everything, warts and all), but it was actually harder than using jump cuts.

There's even a Jump Cut Edition of SFN somewhere back there.

[huyked]

I love this channel. I must recommend it to my brother.

[LEDZEPPEL1N88]

so cool! i love those outtakes rofl
