@Equnoxe when was the last time you have seen a christian priest heard goats ? ... As bad as it is in many muslim states it is allowed to marry underage girls. So by definition they are no pedophiles. Even If I would nail the external sexual characteristics of every grown up on a wall with rusty nails, who would have sex with a child. No matter of race, religion, absence of religion, or gender.

[@BudgetFilmmaking]

@@tuxontour That's wrong for a couple of reasons. 1 the point of the comment was to reference the people who came up with the religious beliefs. They, unlike the modern day adherents, WERE goat herders. And what they did for a living doesn't necessarily make them wrong. But the fact that they claimed things about the universe which are demonstrably false does. 2 pedophilia is not a legal term, it's a clinical one. So even if the legal age was 2, the people who are marrying or engaging in sexual activity with individuals who are not adults are still pedophiles. I don't see how your argument actually addresses the issue. You're just finding off topic reasons to dismiss it.

[@tuxontour]

@@BudgetFilmmaking sorry but I still think that "goat hearder" is used in a rasist way. I have seen it used way to often especially for that reason. And yes being pedophile is a psychological condition... That is at least what is claimed by those aholes. Everything without consent is rape. At what age you can understand what is happening and give consent is different from person to person. But it is at least a 2 digit number and I would say it is hexadecimal. Often I place even 25 years old in a category where they should not be allowed to vote but somewhere you have to draw a line. And no I am neither moslem nor christian nor pedophile. I am just your run of the mill high functioning sociopath.

[@BudgetFilmmaking]

@@tuxontour Lol well this is the part where I would get snide, but I'm afraid that comment has disarmed me sir. It sounds like we agree on a few things. I'll even give you the goat herder thing. I don't think it's necessarily "racist", but it is meant to be a cheap shot. As a fellow sociopath, however, I'm not above a low blow now and again. Either I've confused myself, or we're talking past one another. Where do we disagree?

[@tuxontour]

@@BudgetFilmmaking I think we disagreed on the goat hearder. It disagreed very strongly with me as quite a lot of the "nice" christians love to use that phrase. I dislike people in general not because of their religion or country of origin. But in special I dislike religious people who force their beliefs over other people's lives and freedom. To bad that here is the wrong places to discuss all those things. Logicked channel would fit this topic better. Have a great day and stay healthy

This !i know this is an old comment but I had to agree. I once taught a high schooler enough chemistry in 3 days so that she passed ( barely) her final . She had cut her class the entire semester. She was so proud of herself that when she had to take the class over she understood enough to get high grades . To add insult to injury I taught her this basic chemistry while she was working the register at a department store.

[@Astro-Markus]

Two issues: When you look at the Initial Mass Function of stars in clusters, most of those stars are low-mass stars like red dwarfs. Therefore, any agglomeration of stars is dominated by low-mass stars, aren't they? So, saying that low-mass stars tend to be found in isolation may be misleading. The other thing is that I have learnt in university that spiral arms do not contain particularly many stars as opposed to the space between them. It is just that most of the bright massive stars are there and dominate the brightness distribution across the disk. Stars predominantly form in the dense ISM we find in the spiral arms. Therefore, short lived massive stars die shortly after leaving the spiral arms made of ISM.

Space is so dynamic and interesting! Actually I am reading a book by Prof Joseph Silk, and he talks about galaxy formation. He says that scientists are still unsure about whether galaxy clusters formed first, then fragmenting into individual galaxies, OR individual galaxies gradually became bounded gravitationally to form clusters. Space is fascinating, especially when you try to think about how small the earth is compared to the observable universe.

I get scared when I think that we are most likely only able to see a tiny part of the universe, because only 13 billion light years have passed, and that within that tiny, tiny part, we are a microscopic speck somewhere. The scale is truly unfathomable.

[@davidguthary8147]

12:04 A long time ago, actually never, and also now, nothing is nowhere. When? Never. Makes sense, right? Like I said, it didn't happen. Nothing was never anywhere. That's why it's been everywhere. It's been so everywhere you don't need a "where". You don't even need a "when". That's how every it gets. Forget this. I want to be something, go somewhere, do something. I want things to change. I want to invent time and space, and I know it's possible because everything is here and it probably already happened. I just don't know when to start. And that's exactly where it started.

Intergalactic dust is an interesting thing. The galaxies collide and a large chunk of the gas and dust is blown out, remaining inert and alone in the space between galaxies.

[@Aimless6]

7:30 Are the first stars at 13 bio years in all directions? It is unlikely that we are by chance, exactly in the middle of the Universe. So space-time is many times bigger than 13 bio lightyears. The light from 20 bio lightyears away just hasn't reached us yet.

[@ProfessorDaveExplains]

There is no such thing as the middle of the universe, it doesn't work that way. But yes, the observable universe is not the entire universe, and we don't know how big it is.

[@1251caveman]

@@ProfessorDaveExplains The thing is, the whole universe came from one tiny subatomic-sized singularity point from the big bang so there should be like a "center/middle" part of the universe because that's the area where everything came from, right? Or maybe the universe is so mixed up in all directions it doesn't work that way like you said?

[@ProfessorDaveExplains]

Common misconception, spacetime itself is expanding, there is no center. The classic analogy involves blowing up a balloon, where we take the 2D surface of the balloon to represent spacetime. There is no "center" of the surface of the balloon. Bear in mind this is a lower dimensional analogy, it is impossible to visualize the reality of it.

[@1251caveman]

@@ProfessorDaveExplains I guess that makes sense, the observable universe model that we see isn't a perfect sphere but an irregular shape then, with different edges of the universe expanding at different speeds? Or does that idea violate any principles of the expansion of spacetime?

[@OubleJum]

you will always appear in the "center of the universe" because all the oldest light reaches earth at about the same time from all directions, because all the time that has passed in the universe has made it so all light in the universe traveled about 13.8 billion light years, so anywhere in the universe that is at or more than 13.8 billion light years from a theoretical "edge" will always appear in the "center of the universe". for all we know, the universe can be infinitely large, all we know is the approximate age, from the evidence from how far light has traveled.

if elliptical galaxies are formed from colliding spiral galaxies, where are the pop 1 stars? if elliptical are predominantly pop 2 then wouldn’t we assume elliptical are the elder formations?

[@mihaioancea608]

Hi Dave. I heard a theory that these supermasive black holes in the center of each big galaxy have formed different than the stelar black holes. Shortly, that big cloud of gas somehow ignored the steps from the birth to the death of a high mass star and simply formed an enormous black hole without any fussion to occur. And the theory is sustained by some limit of how much material can a black hole swallow during a period of time. For example the supermasive black hole pictured last year in april wouldn't have had enough time to feed that much from 3-4 sollar masses (mass of a typical new formed black hole). It would be awesome if you can reply with your opinion about this theory and I hope I explained it good

[@TheNeptuneArc]

Actually, there have been at least a couple of cases of galaxies hosting no supermassive black holes at their center. So "every large galaxy" doesn't have a SMBH at their center. Good job on the rest of the video!

[@Skeptical_Numbat]

Sweet. Excellent basic knowledge that I reckon everyone should learn as a child. You may also have mentioned that the *Milky Way* (our Barred, Spiral Galaxy) & the *Andromeda Galaxy* (a neighbouring galaxy in our cluster) are en route to collide in 'bout 4.5 Billion years. I dunno if humans (as we know them) will have survived that long into the future (⊕), but - as it will create potentially millions of stars - it promises to be quite a fascinating event for any Sapient species around to witness it... ⊕ - I suspect that we would have speciated into dozens of new organisms by then. ; )~

is there a limit to the observable universe? also, this last statement raises some interesting questions. If we are able to colonize everywhere, is it our galactic "manifest destiny" to spread everywhere? if not where do we draw the line?

[@ProfessorDaveExplains]

Well yes, the limit to the observable universe is the age of the universe, since light can't travel farther than it has had time to travel since the universe began. As to colonization, I don't know about "destiny", it's just a thing we can do if we become able to do it and choose to do it.

[@ProfessorDaveExplains]

ah but clockwise according to whom? go look at it from the other side and it's going the other way. since there is no preferred vantage point in space, it doesn't make sense to say that any galaxy spins clockwise or counterclockwise.

[@freddykrueger6571]

@@ProfessorDaveExplains Some beam of (something) shoots out of the front end of the black hole. That tells you which way is "up" for the black hole around which a galaxy revolves. Relative to that beam, CW and CCW can be defined. So based on that theory, CW and CCW are not arbitrary. Another way to look at it - Stars and planets fall into a black hole "one way". That one way can be considered "up" (or down). Upon that, the definition CW and CCW can be clearly defined. Is it possible something can fall into a black hole from above, below and sideways? Is a black hole like a toilet that is flushed where all the water goes one way...or is it more like black sphere where everything all around gets sucked in with equal force? I think its the former.

[@ProfessorDaveExplains]

I'm not aware of any flares being emitted from supermassive black holes that go in only one direction and not both, relative to the plane of the galaxy, but even if there were, it would be arbitrary to call that side the "front", it could just as well be the "back". As for how matter falls into a black hole, that is completely omnidirectional, matter can fall into a black hole from absolutely any angle.

[@kleonymos5726]

[@colincampbell3679]

One thing has been bothering me about Black Holes? To be exact, the quasar versions in big galaxies which shoot out huge jets of matter from their centers! How is that even possible? The known fact is a black holes gravity near the event horizon is so strong that nothing can escape it.. And we are told that quasars throw out matter at great speeds.. The way we are told this happens is the black hole/quasar is feeding too quickly and some of the matter in the event horizon is spinning so fast it get's thrown out! That's the problem here.. this statement is opposite to the fact black holes are so strong gravity wise nothing can escape not even light. So how the heck can some of the matter not only escape the black hole but shoot away out of the core into intergalactic space? Because for it to do so would mean that that matter must be moving faster than light to escape the black hole, And this is a super massive black hole so the gravity would be many times higher than a normal sol mass black hole.

[@ProfessorDaveExplains]

Not faster than light, it doesn't actually escape the black hole, it's not within the event horizon. It has to do with angular momentum, it's complicated and I'm not sure off the top of my head.

[@scptime1188]

Isn't that matter meant to be stuff that was already orbiting the black hole, not within it? I'm pretty sure magnetic fields get spun up by the black hole and charged particles are flung outwards. Whilst I'm not sure of the current status, I'm sure this was meant to be contested at one point. Read the wikipedia page on "astrophysical jets" if you want more info

[@goldenhorde6944]

Colliding with just about anything on a cosmic scale is actually quite difficult, since the closer you get to any source of gravity the more you accelerate from said gravity, increasing the chance for you to miss and enter into an orbit instead. For example its part of the reason why the recent Parker probe flyby of the Sun was such a big achievement, getting that low is actually exceedingly difficult due to the gravity involved.

a red giant is more massive than a white dwarf so it should suck the white dwarf because the red giant has more gravity

The red giant's mass is spread out through a large volume of space whereas a white dwarf is a ton of mass very highly concentrated.

but also ancient stars and that's why we have were it's very rare that we are going to say we have wide open deep dark distances between space spaces it safe but it's because those group of stars there have blown out and now it's not all and all that that doesn't just happen there it happens like a butterfly affect you will see that the differently different opposite thing happened to the black ⚫ out In outer space seee one set of stars they blown out but ours hasn't then they were also ancient stars and star system's and A black hole to but also the crystal skull to and then to think of it which is also Cosmic straw and then you have wide open dark distance distances of outer space those fast deep dark distances of outer space are where the sets Stars blew out but that's the entire outer space you will see how it looks like a pattern and all that around it if those those other galaxies are not connected to any other galaxies and then there's some that are in our is a Galaxy by itself which is the Milky Way galaxy reset at Achilles heel and because we do and we're not in the archers Bowl the bowl at all are you going to party Arrow or even a part of the arrowhead which is Eros and that means that God put us at the bottom on everything so how do we get there you look at the arrowhead and at the tip of the Arrow Head that's the Galaxy God's if you make it there we may be able to see things quite or clear clearer in entirety all of the galaxies together all the empty Open Spaces those are Where Stars blew out before and because they blew out there and no longer are there they become vashtie bottomless Darkness and deepness voidz like a pit itself within a pit because outer space is the bottomless pit and now that you know that it's because I used to be one of the ancient astronauts alsumaria when they made the Sumerian texts I was at an i and I was Heaven basically and everything you see out there basically everything out there and everything in between was a part of me no matter how it looked and then I seen the plains in between Kyle like the first Solace zodiac system charts in the numbers like air but yeah ancient star systems that have blown out Arlo ancient demons because they've blown out long ago and because they blown out long ago that's why they're the demons or sunlight which is ancient sound like most of them are and they're out there still the ones are glowing and you can see and if you still can see you might be seeing the reflection of the light that's there because they're not black holes have been eating away at outer space It Raw dark outer space itself and all the spaces that was in between that so now you see a reflection of the Galaxy that once was there so don't get food and go there cuz that's what it could be anyway just had to let you know that are black holes are not nice like they're not interesting the wormholes are the ones that are interesting because they release to take you places and then maybe to heaven somewhere and now a black hole is maybe interesting in a way but it's to have a control over full control over gravity at that point in time any other way black holes are dangerous and can be known as unstable and you shouldn't really mess with that if you're not God and if you really want to know a lot more you can message me here on KZbin but I can see your head into a lot more then but and then also tell you a lot more about what I'm talkin about but ya ain't your star systems that blown out or actually ancient demons and actually our demons when the Starchild comes or the sign child comes a son outside in outer space somewhere else will blow out somewhere else or even a whole galaxy we'll blow out which could send shooting stars to outer space at that point of time but the ancient demons are nothing to be worried about unless you've done something wrong against God and me you really don't have much to worry about so don't worry really I just letting y'all know really what stars were and why you humans are sore measure Mariah's by the stars and thinking God's not real and you know it's all because God is real because I mean why would he make you and then not be real himself to like you know Libby limited breathing but somewhere else and other things like other people in like other planets you know I'm saying but y'all bring their small and you are human see he will fill your head in with that because y'all humans tend to kill and murder one another and that's why God don't want give y'all any instructions plans to anything of mass destruction if you known you hoomans if it was left in your hands y'all would pretty much a pending don't y'all doing with the inevitable and God he's glorious and he's Divine and that's why it's more of that God has control right now then you humans cuz you don't think all the gather like him just yet y'all don't use most of y'all bring which God brain he does use most of his brain he has access over his whole brain and y'all don't have access of your home right which he could do certain stuff heal his self heal people talk nice polite be sweet time walking like other man get along with everybody every sack every raise no matter who it was even if it was a devil and that's the truth cuz God came before he was Jesus Christ the devil was his best friend cuz he created the devil and the devil turned on God and he revealed so gothram out of heaven so therefore God did get along it with the devil at one point of time there's just that he's the one that chose to reveal against him and he chose to lower life because he chose these rumors down here which is a lower life than a god which is divine and inevitable and things that is ending and always to Xfinity so he's got a finiti we have zero to Infinity because we got a live a life to get to Xfinity if we don't live our life first and we don't live the life the right way will never get to Affinity get what I'm saying all right and now that I feel Jarhead and with that and this is really what I was thinking and to tell y'all at this point in time God told me to instruct y'all into letting y'all know what that actually should was really out there why is it meant to confuse you if you were atheist and you don't believe in God and why you look at outer space and then say well there's got to be something else if God made this there has to be something out there is what I would say because it says that in the Bible when he said let there be light at that time I believed at that time he meant Let There Be Like That mint and other places too so then he made the other galaxies to when everything cook down and melted to there at that time he made all that other stuff like that out there to even if there's Echoes of like different walls of time too and they were like the same exact reflection of what we look like in heaven but down here to you get you get it to where you have bigger bodies in heaven and down here you're small and puny because you're human butt up there your glorious and bright and bright as the sun like sunlights like even big bright lights and like even big sons of Glory theirselves like is you was a baby and you was in the spirit and you was a soul you would be out there drifting in the darkness and outer space right and you would actually be that sunlight and you would blow out there because that part of space was empty there and there was no one that care for you there at that point of time there so didn't want to be a sunlight okay and here what is somebody that really wanted a baby and you need it to have that baby you wanted to really have that baby he was dreaming to the stars and back okay and then when you pray to God you wouldn't start baby right so and and you like the stars and you like the galaxies and panic you prayed you you wanted to start baby right so that's star blew out out there and now that babies born here just like that that's what you brought back you brought back basically God and also not just knowing god you brought back star children which was me with diamonds start your child I am a star baby and my children and everybody's children that was probably born Riley between the sixties and the late 90s good let me tell you this is actually like the truth and people did and they say I want to start baby star baby star baby star baby please come start baby I'll start baby of mine please see our baby of mine come out of the stars and give me it yourself you are so Divine sorry baby star baby sorry baby of mine because this is the song people with singing now you have stars that have been born real stars that right here are on this planet real stars that were actually out there in outer space have been born right here on this planet not just somebody that's got a open mouth that God dang tongue and then open your mouth and has a big braids and big up Rantoul acting like God thinks Broly hundred percent of Parental active and intelligent very wise and wisdom beyond their years is that that it's just that that too on top of it that that they'll no other shit that you don't know that even save the world but people won't be listening to him they won't open their mouths they won't listen to him and they won't even open their mouth about certain stuff or serious stuff that goes on in the world and they do not care for that matter I hope you cared hope you listen if you did your message me back if you didn't who cares whoever

Hey Professor, you mention "elliptical" galaxies several times without ever explaining what that shape means. Tell 'em that means "spherical" in shape.

[@GammaStyleGaming]

The aren't spherical. Look up what an ellipse is.

[@theaviator1152]

Elliptical does not mean spherical. Those are two different dimensions. An ellipse is basically an oval. It’s a circle where two parts across from each other are stretched apart. Ellipses have two focal points-a circle is a special type of ellipse where the two focal points are the same (the center of the circle).

Don't you think there is a single God is present behind all these to manage all these things? Or it is working by itself?

[@ProfessorDaveExplains]

I don't believe in such an entity personally, but it is not specifically inconsistent with science at the present time.

[@dekippiesip]

Gravity is what manages all these things.

stop teaching false facts! The milky way is a sphere lol

Well none of astronomy makes sense outside of the context of the big bang model, so you've gotta choose, all or none!

[@yasseranwar4890]

@@ProfessorDaveExplains You are right but for me ,I cannot accept these theories for grant . I am not obliged to do that(remember Halton Arp). but why do not you think outside the box of the big bang , for example , if we assume the heaven is not just a blue color as science claims ,and deal with it as an infinite curved mass (as it looks ) everything will be explained without needing dark matter.Science goes the wrong way .

[@ProfessorDaveExplains]

It seems like you are trying to make science conform to your religious beliefs. Of course you are free to try to do so, but you are misusing scientific concepts in this act, as it sounds like you do not understand the necessity for dark matter in physics, or what we know about it. Be careful in convincing yourself that you understand science better than the entire scientific community.

[@yasseranwar4890]

@Specane and has a lot of flaws , the big bang never happened but in yous minds

[@tonyhartness2123]

Why do so many creationist have a problem with science? I have lived long enough to have changed my views on just about everything I believed or did not believed in... One thing that does make sense is our ability to learn, and it's been slow at times, history proves this much. If there is a creator ,why is it so hard to believe that he could have used a process to create this universe. And if that is the case why is it so bad to believe in the Big-Bang theory. Like that old ass book says we were created in his image. I would have to think that means more than just appearance. Meaning our ability to process, observe, think, and learn. Why else would we have the brain we have? And a true father would be proud to see his children solving the mysteries he created. I have never heard, seen, or read of any scientist trying to disprove your god..

Stars also die❓❓Do stars have souls❓❓Deny it or ignore it but there is definately a Creator who created all these. My pranam to the creator🙏🙏🙏🙏🙏🙏🙏🙏🙏

[@user-iv1qz1tx7u]

I don't know if it's a joke or a legitimate question, but I will answer as a legitimate question since you or other people might be in doubt. First we can't prove anything to have a soul, not even humans. This is faith, not a scientific fact. Assuming living beings have a soul for the sake of the argument, stars aren't "alive" biologically speaking, they are just huge nuclear fusion reactors, to make it simple to understand. When we speak about life of a star it's only to explain the processes a star goes through during it's existence, but a star is as alive as a nuclear plant, machine or a water bottle: Not alive at all and no soul to speak of.

[@simantinisinha6604]

Thiago ok stars are ball of gases made of hydrogen and helium. All humans, animals have souls. Those who have breathed first will breathe last. Soul lives the body after death. Science also proved paranormal activity, ectoplasm, etc. There are many things beyond our realization which we can see

[@user-iv1qz1tx7u]

@@simantinisinha6604 Well, citation needed! Where and when does science proves ectoplasm? Ghosts does not exist friend! If you *believe* on ghosts, ok *you* can believe in anything you want but don't address science as a believer in the paranormal, please. And a star is not made of gas, it's plasma, the fourth state of matter, not the third. Oh and before I forget professor Dave has some great videos about science in general, you should watch them. I actually recommend his channel to my physics highschool students. You should watch his content, he explains really well and will help you understand our universe.
