  • I know this is a really stupid question, but HOW do I check out the latest Tony Darnell video? I mean, I'm subscribed but dates seem to jump all over the place. I love them, of course, but there are so many great things being discovered and discussed, how does 'grandma' here find the most recent tdarnell video? And...I hate to tune into these "god" discussions, even momentarily, looking for a recent date!

  • just imagine if big bang was just an experiment of an other alien race or something beyond our imagination.

  • Anyone know what this song is?

  • amoralis123, in science, a fact is something which is assumed to be true until it can be disproved.

  • Big Bang is a conjecture. Eyes receptors of Microwaves? What nonsense in the name of science.

    The sky is dark at night because it is filled with Dark Matter, still under research. Please do not make Science a Religion. Science deals with facts. A Theory when proven becomes a Fact.

    Please tell only what is Factual as a Fact. Thanks

    A good video. Keep on. Ignorant humans need to be enlightened, lest they fall prey to Religion. Save them.

    Of course, I am a non believer.

  • Thanks. Your postings are really excellent and informative..

  • Just a quick question, if you pause at 4:44 what is that large dark "rip" that goes across the universe? It kinda looks like a giant equator.

  • @realchris1Returns It's the galactic disk. We can't see through interstellar dust in visible light.

  • If you look at the right lower corner of the screen at around 5:10 you can see an evil alien face, these are the gods of the universe!

  • Does that look flat to you?

  • THX tony ....yoUR VIDEOS ROCK

  • this is stupid

  • @MysticalMannequin you're stupid

  • @knigthfigth i know your stupid

  • @MysticalMannequin no you

  • @knigthfigth yeah you

  • @knigthfigth yeah you 

  • Awesome.

  • i feel a lot smarter after watching this

  • @Ozielhc time laps videos

  • we build telescopes... you wrote a boring book.... lets get with it people..

  • @Ozielhc Yes my friend.Just search for Milky Way timelapse view you will find amazing videos.Enjoy!

  • theres no sky in night

    theres no sky in night so we can see those twinkling stars

  • Comment removed

  • I want to die while staring at those stars at night, and i want my corpse to be thrown outside our solar system

  • Excellent video! 

  • The "infinitely old" universe sounded a little bit confusing when I first heard it. I took it as "infinitely deep" in the first place instead of "ever-unchanging", if it so, I just thought there was no way for every-single ray from a star to reach our eyes in the universe. Hmm.

  • I don't quite get the paradox - even if the universe was infinite, you still wouldn't see brightness everywhere simply because some stars are too weak. You wouldn't see a light bulb from 1000 miles away although it's there.

    Beautiful pictures though :)

  • @maximkazhenkov11, but if there was an infinite time to allow light to travel through space and an infinite number of stars to reinforce the weak star lights it should not have been a problem for the weak star lights to reach us. The weak star lights should have reached us by now coming from infinite time past and reinforced by the infinite number of stars in a universe that is static & not expanding (it must be static for space to be infinite). Expansion implies a finite space/universe.

  • @maximkazhenkov11 a 100W light bulb wouldn't be seen. But if there was a 100,000W bulb behind it, that area would be covered w light.

  • @petepittsburgh no because the weaker star would absorb the light from the brighter star, preventing it from reaching us.

    

  • Wow this is fucking amazing.

  • the only planet in the vast cosmos who is being "illuminated"- sure, one 100 W bulb can illuminate a lot of space provided it's empty as a perfect vacuum, and the cosmos is never a perfect vacuum: full of dust and matter, including over 90% Hydrogen which absorb a lot of this energy (photons), when viewed through other spectrum the Cosmos IS INDEED BRIGHT AS DAY LIGHT! That paradox is pure idiocy.

  • Childish "paradox". The fact when facing a paradox in a scientific matter this is an indication of something gone wrong (i.e. a wacko theory). This bullsh!t is based on the premise that scientists know everything that need to be known; in fact even today they don't know exactly what is "light", never mind more important question, where all this came from and how old it is. Cosmos is not empty, even the voids are full of matter; light is a form of energy, eg. it can be absorbed, and we are not..

  • That was amazing X______X

  • I hate that you call yourself "americans" as if EEUU where the hole continent. Pricks.

  • Americans should be banned from the interwebz. Every freaking Youtube vid is drowned by their imbecile 'debates' on creationism and shit. I had to look up what creationism was lol

  • @lexsite Its not all Americans, just the idiots. And keep in mind that their are idiots every where. The only reason why it seems like there are more idiots in America is because it is easier for the idiots to get online and spread their filth.

  • @lexsite well I'm American but I'm an Atheist, along with 93% of our scientists. Not all Americans should be banned, just the dumb ones xD

  • Creationists need not feel threatened by the big bang. The big bang theory supports the notion of creation because there was nothing....then suddenly, something. Nothing became something....creation. Not sure why creationists are bothered by it. Why aren't more atheists against it, is my question.

  • @dlynn1580, many scientists are agnostics (Existence of God could neither be proven right or wrong - we can never know if God exists or not) and they are not against the Big Bang because the physical evidences for it is so strong and solid. So they are proposing the M Theory on how the universe came to be from nothing wiithout the need for a Creator. It came by itself through "quantum fluctuation" in a vacuum. They applied the concept of quantum probabilities.

  • @csdr0 It may be difficult to disprove any Creator personage, but it is not difficult to disprove the Sunday worshiping God. Why do intelligent people give the radical fundamental churchgoers a break? Abraham's God is false. That's all you need to disprove to have a better society.

  • @csdr0 You got it wrong, the existence of god CAN be proven right, it might be harder to prove it wrong though, but it's not up to atheists or scientists to prove it wrong, it's up to believers to prove it right, if they can't, we have no reason to believe, and we have an even stronger reason not to. But back to proving that he does exist. If the religious fables of man turn out to be right, there's so many things that we could verify from them, but we haven't verified any of there claims.

  • It's wrong if this video gave me a Boner? :/

  • yay

  • I just got mind Fucked.

  • I was watching this with dbz and i heard the universe should die LMFAO...

    i want space pie

  • Love your videos Tony!

  • Light waves are shifted and not visible to the naked human eye.

  • I know why. It's because the sun's on the other side of the earth. Booya.

  • Stunning

  • The Big Bang was no "Ball" and not even a "Bang" as it is often described.

  • Hey! I was the 1,000th like for this video!

    Do I get 1 free universe?

  • @migduh for you, weve got 10

  • It is people like tony that gives hope for the humanity. Never stop making these videos tony. It really is a breath of fresh air in my day.

  • i Favorite most of your videos :) i love them.

  • And black is the absence of color. Btw theese videos blow your mind when your faded!

  • i looked up when the video ended

  • I had to laugh when I saw the title of this video because it was so provocative and excited me. Thanks for the video.

  • Very good video, this should be on the discovery channel or something

  • I love the conclusion!

  • Hi, can you say somethings about your technic? Shots per second, aperture and exposure time ? Camera etc. ? many thanks !

  • well done

  • The night sky is dark because thats how large space is. Despite the trillions of light sources the sky is still black. Its a testimony to how far and wide the universe is. The fact that there are suns many times larger than our sun out there and they only appear as dots (stars) in the night sky tells you that space is ridiculously big. Its like looking into a cavern with no lights only that space has lights ......and its STILL dark.

  • @ReeseMac It's actually because light is invisible until it hits something reflective. This is why you don't see beams of light whizzing past your eyes. Space is empty, therefore it is dark.

  • @jacksawild .....light isn't invisible.

  • @ReeseMac You really should check google to stop you form saying silly things. If light were not invisible you wouldn't be able to see anything on a sunny day because of all the light getting in the way. The only light you see is the stuff which hits your retina. i.e the stuff coming towards you. It is a well known principle of optics.

  • @jacksawild ......"the stuff"?...nevermind , dude....move on

  • There's something I have never really understood about the idea that the sky should be white because we should receive a photon from every direction. If there is a star in one direction, it doesn't mean that at each instant t we receive a photon. We could receive a photon at one time t and another a fraction of a second later.

    It seems to me that the sky could still be dark.

  • Do not DEAR to kill your unborn child. If you do, you will die with him and your life will become hell on earth. Have mercy on him and on you and on the father of him. If you do, the father of your child will be already in hell and you will join him after your death. But your child will be with God and you will be not. You will be together with the father of your child in hell. If you DO you will regret for all eternity.If you DO would be better not to be born at all, and father not to be born.

  • So, you assume there were not enough high-energy photons in the begining which after undergoing Doppler's shift would fall into visible spectra?

  • it seems like the photons would pass and the light of stars would pass while new ones appear

  • My head is Gunna explode thinking about this so if there was nothingness then a bang how could this be? As nothingness is like a vacuum of air ??? Wa head hurts now

  • @SuperKaloe

    No all matter that has ever existed has always existed...

    Matter cannot be created nor destroyed.

    Just imagine the Big bang as an expansion of what was already there.

  • Imagine, one day we could see microwaves with augmented eyes...

  • It's dark because God forgot to change the light bulb.

  • Wouldn't it still be a mystery to Kepler and the others though, because microwaves cannot penetrate Earth's atmosphere, and therefore the night sky would still be dark to their microwave seeing eyes? Isn't that why we needed to launch the Planck telescope into orbit to conduct its observations? Someone correct me if I'm wrong.

    Otherwise, great video as always Tony, thanks!

  • @IneptTroopr Microwaves absolutely do penetrate the atmosphere, and it is how communication is achieved with satellites and orbiting astronauts. There is a broad spectrum of microwaves with varying penetrance through the atmosphere. It was actually a ground based radio telescope that first detected the cosmic microwave background radiation.

  • @IneptTroopr Microwaves can penitrate the earths atmosphere, they can be very dengerous to in large amounts and can damage or even destroy parts of the earths outer atmoshere. The sun produces microwaves in the form of solar flares, the microwaves are radiation and can even destroy satellites that orbit the earth. However the radiation from the far out universe is to weak to do any damage but we can still see it.

    The reason they use telescopes that are in space is to get a much better view

  • nice vid, Tony. thanks as always :)

  • Love this video! This gets a thumbs up & favorite. I've been interested in astronomy ever since I was child, the universe is full of wonder.

  • Thank you for these wonderful videos.

  • The sky isn't dark at night, it's brighter.

    :)

  • Is the light enegy not changed when it tranforms into matter?

  • @MrPhillerup yes but not all of the photons would have been transformed.

  • The end image of the big bang looks like a pulsar. o.O

  • Very good video. Thanks.

  • tnq stumble.

  • keep looking out..

  • Your believe in these theoretical constructs does not make them real.  Show me some dark matter and we'll talk. Science requires more than faith.

  • 4 Creationists hate this.

  • @Screbus I don't hate this. But until Science can explain Why the universe Came into existence. I'll stick with my belief.

  • @outbackjack1974 hey, science states that our universe has in fact a origin (the origin of space-time). The big bang is the biginning of everything. By everything, it includes time. Therefore it is meaningless to ask what was before the big bang. Or we may say that the universe imediately after the big bang has always existed. Beliefs are a great help for emotional purposes as well as unanswered questions. But they can also be a great obstacle.

  • @Screbus This doesn't contradict Creationism at all.

  • @Screbus GG, you failed at stereotyping.

  • @Screbus Ancient creationists--even though they were wrong about the age and spatial arrangement of the universe--knew more about astronomy and the night sky than you ever will. That you think this video is even relevant to creationism just proves my point.

  • @smmclaug75 How did the ancient creationists know more about astronomy than we do today? And how do you know what they knew about it?

  • @Screbus I am a creationist and I love this. Don't put words in our Mouths please;)

  • @Screbus tis now 9 :P... the cult is growing

  • Good, but it does not preclude the possibility of an infinite universe. The big bang theory is still very new and unproven. There is still debate about it, despite what mainstream dogmatists would have you believe. There are a lot of purely speculative mathematical entities used in modern cosmology that do not really explain anything; e.g. black holes, dark matter/energy.

  • Comment removed

  • @AntiFed1791 dark matter explains why spiral galaxies spin at the same speed near the middle and at the edges, much like a frisbee. If dark matter was not present, there would not be enough mass for this to happen, and the center would spin much faster.

  • What if space stops expanding after another 13.7 billion years the night sky would be much brighter with more gamma rays hitting a lot harder.

  • off the top of my head, because the Earth blocks the Sun

  • What's the name of the song?

  • Great video, but please make either your commentary louder or the music part softer.

  • simply, " the best videos on you tube!"

  • beautiful viedo honestly

  • That was a beautiful picture. Thanks for the vid that was cool!!

  • COBE is not a basketball player. WMAP is not a map.

  • That really puts the big bang theory into perspective, awesome video!

  • thanks so much for posting, means alot.

  • Wow, Tony, this one is so great! Really nice work! :D In my honest opinion, this is the best video after the Hubble Telescope one, which is really hard to top.

    Keep them coming and I will keep looking up! :)

  • I'm confused. We don't see an incredibly bright sky at night because the distancing of other galaxies and other stars makes it less likely for light to reach us?

    I know, I'm stupid and scientifically illiterate.

  • @kindthrone No the distances that the photons (which we see as light) have to travel from the long distances of other stars get so stretched out that our eyes aren't sensitive to seeing them as light anymore. If we had microwave sensitive eyes we would see the sky lit up all the time.

    Hope i explained it clearly and correctly ha....and ur not stupid

  • @BossBajos Oh, OK - now I get it. In a very science-is-hard-I-want-to-go-b­ack-to-literature kind of way, but I get it, thanks.

  • @kindthrone Yeah, bossbajos said it better than I could.

  • @kindthrone Think of it as the distance between us and the very distant galaxies is so great that there hasn't been enough time for the light to reach us. Keep in mind, it's a very basic way to look at it.

  • @brmadman4455 Thanks, seems I didn't misunderstand it. So technically the space between galaxies shifts faster than light?

  • 0:12 UFO ftw!!!

  • if the sky looked like 4:37 at night that would be amazing

  • why dont i see god in the background? OPPS spoiler alert

  • thanks. great explanation of microwave background radiation.

  • fantastic video tony! keep them comin, love it!

  • you rock dude

  • GAWD I love your video tdarnell. Don't ever stop! Get Discovery network to hire you!

  • But what about Dark Matter?

  • Wimp stole your video man.

  • Very nice video.

  • There is a simple explanation for why the sky is dark at night.

    It's because we have to be able to sleep at night.

  • @Redrumtester

    Other way around, dude. We sleep at night because it is dark. :)

  • Nice video

  • Beautiful video.

  • So if the universe wasn't expending we would have so much light it would probably blind us?

  • @oleHABSole Chances are, when we evolved eyes they would have evolved very differently.

  • pretty sweet...

  • So assuming the "Big Bang" what was before it. Why is there anything at all? The real question is where did all the matter/energy even space-time that occupies our universe come from. Where did the energy of the "Big Bang" come from?

  • @watchme2day From a documentary I watched on discovery, they claimed that our universe and a parallel universe collided causing the big bang.

  • @stephang4g You're referring to M-theory, or the eleven-dimension tangent of String theory. As hard as it is to comprehend, Science Channel's 'Through the Wormhole' (with Morgan Freeman) did quite a good job of simplifying it—episode 4 'What Happened Before the Beginning' may be the show you're referring to.

  • @watchme2day The question "what was before the big bang" is meaningless because time is a feature of our universe. There was no before before our universe. As for where the energy came from, there are many books that address this topic. But the short answer is it didn't come from anywhere, it's canceled out in the long run.  It's too complex to explain in youtube posts. Google it.

  • @watchme2day You can't intuitively sort you way out of this mess. If you're going to apply the theories in earnest, then you know there wasn't Space-Time prior to the big-bang. So asking from where, or from when, did the "energy" come, has no meaning before the bang. Space and time are a byproduct of the big-bang, not something the existed in dark silence waiting for some sort of energy bomb to be dropped into it.

    Go read philosophy to "answer" this sort of question or pickup a religion.

  • The expanding universe stretches wavelengths of light the same way an ambulance sounds different when it's approaching you as opposed to after it's passed you. The wavelengths are smaller as the ambulance comes towards you because the sound waves are bunched closer together, and wavelengths afterwards are smaller because the sound waves are spread out. Same thing happens to light.

  • @273C You're just parroting what you've heard in videos or books like this, but you didn't really think about it.

    Even Einstein would shut you down for not getting it. And it turned out, he was wrong.

    But you do have the right idea... sort of, and I appreciate the enthusiasm.

  • very good video!!!

  • Nice, now I get it xD

  • The sun is much closer and fills the sky our sky with photons and in our atmosphere becomes what we call day.

  • That is hardly the reason why the night sky is dark, its do to space being a vacuum. If you look at images of the sun you don't see light rushing out from around it, and filling the heavens. The sun only lights up the sky here on earth because we have an atmosphere. The stars are so far away that there are spots in between them and the number of photons that come this far from other stars are very few, they don't fill the sky and we only see points of light in the night.

  • @SunFireDragon

    u r supr smrt

  • @SunFireDragon

    you misssed the gist of the video...

  • AWESOME!!!!!!!!!!!!!!!!!! THAT IS BAD ASS

  • I can't comprehend how the universe expanded and what that means for todays night sky viewing. I don't doubt the video I just can't comprehend it. Same goes for relativity theory and quantum theory. It's far out there ;-)

  • Quick question,If the earth was made by the Big Bang Theory.......are other planets made from thier big bang theory also ? Now it just so happens that earth slipped its way right into a perfect spot between other planets,and if earth was made in this way why aren't other planets so lucky to be made the same way and be usefull to humans.

  • @leondugue All planets, stars etc. were made by the same big bang. They developed into what we know today with time, at first it was just energy, then the first particles formed, atracted each other, forming the first structures, gravity kept things together and with time, the first stars formed, after those stars died, the variety of elements raised so the planets started to form ... really, it's a long history, you should look it up though, it's very interesting ...

  • @DarkZholt According to modern big bang theory and inflationary theory and m-theory, and quantum field theory, no, not at all. That's completely incorrect and a gross misunderstanding of energy v matter and quantum field theory.

  • @jimmybilbo I was expecting you to correct me, come on!

    I explained it in a simple way, I'm not a scientist, but still I got something, even if there are missconceptions in my explanation.

    Now why don't you point what is wrong with what I sayd, I would be glad to know (really 8D), sure, unless you'd happen to be trolling and I fell for it ...

  • Are you the narrator?

  • I actually just read about this in a book called "Endless Universe" which explains the competing theory to inflation known as the Cyclic Theory or cyclic model. I was wondering if you could possible do a video about this alternative view of the universe. The book goes on to explain that the new satellite project LISA might be able to detect cosmic gravitational waves from the big bang. The discovery of certain magnitudes will help support/disprove either the the cyclic or inflationary models.

  • Brilliant! Thank you very much for posting this vid.

  • Brilliant video

    I had no idea that such a fundamental question had only just so recently been understood.

    Gregg

  • The sky is dark at night because it's night time DUMB ASS! No seriously, it's dark at night because God turns of the light switch(HELLO? YOU DIDN'T KNOW THAT??!!)until around 6-7 a.m. the next morning! You better praise God for being so loving and caring to us!

  • @mythicalhell Let me guess; you also think the Sun revolves around the Earth and we are the center of the universe. Am I right, or am I right?

  • @NizzBomb69 Finally, you got something right!

  • dam i cant see anything in new jersey

  • Totally agree with @RaenD, keep up this excellent work. Thanks.
