  • NO EDGE

  • Dude....No Edge!

  • No Edge.

  • @Litheran So with this information it would be easy to just assume that if x=0 then z=+∞. So why is the answer to anything divided by 0 not ∞? The short answer is that not all infinities are equal. When actually applied in calculus situations dividing by 0 isn’t so much an end to itself as much as it is a sign to the person doing the math that something went “wrong” and there needs to be further investigation to find out what that division by zero means. Because not all infinities are the same

  • @Litheran obviously as the number you divide by gets smaller the quotient gets larger, in fact this is a relationship often expressed as “as x (the divisor) approaches 0, z (the quotient) approaches positive infinity” the opposite is also true, “as x (the divisor) approaches positive infinity, z (the quotient) approaches zero”

  • @Litheran If you take any real number (whole, fractionable, irrational, it doesn’t matter), lets assume 7 because it’s my favorite number and easy to type. Please excuse any rounding I do here. If you divide 7/7 you get 1. 7/6=1.166667 , 7/5=1.4 , 7/3=2.33333 , 7/2=3.5 , 7/1=7 , 7/0.1=70 , 7/0.01=700 , 7/0.0000000001=70000000000 .

  • @Litheran to put it another way, lets divide by zero. Most high school and bellow math classes tell you that you can’t divide by zero, that it’s impossible, or that the result is “undefined”, depending on how much your teacher thinks you already know. But for centuries dividing by zero was said to result in infinity. Even the twenty year old textbook references my old geometry teacher had still used that reference. And in calculus and higher algebra it’s clear why that is.

  • ... So the infinity between x and z is twice as wide as either the infinity between x and y or between y and z.

  • @Litheran It doesn’t matter what you’re integers are. Lets use letter variables to make this less number-specific. Between x and y there is an infinite amount of permutations/numbers that exist. And between y and z there is another infinite amount of permutations/numbers that exist. So between x and z there is also an infinite amount of permutations, but there’s more than just the amount that there is between x and y or y and z; there’s twice that many, double infinity if you will. ...

  • So I got a text shortly after the 2 minute mark and wasn't paying attention and when I tuned back in I was like "Wait, how did we go from the end of the universe to snow donuts?!" Teehee

  • BananaNeil is correct. There is an end to space but we can't see it because it's too far for our telescopes to see. The most common theory of what is beyond that point that I've heard is if you think of our universe as a bubble in a bubble bath full of bubbles all of the bubbles would be it's own universe and potentially another version of our universe where any one of us could be president or a serial killer.. Or it could just be completely different. Cool video! Loving the Q.O.T.U. series!

  • Snow-nuts! Donuts for when it's snowy!

  • Does everything move at the same speed from the original starting point, because if it isn't that would make estimations so much harder...

  • Wait... is ThatZak?

  • KRISTINA AND MORGAN AND LIZ IN ONE VIDEO? I LOVE YOU ALL!

  • BOOM SCIENCE!

  • i think neil and i could have great scientific conversations.

  • you can make it through the snow i promise lol. you just need to drive a little slower

  • there is an end but it is moving outward at the speed of light so nothing could possibly get to the end of it

  • If you believe the universe had a beginning i.e. that time had a finite start, then we have to assume that the universe is also finite in distance surely?

  • If we estimate that the big bang happened 14 billion years ago and nothing travels faster than light then we can estimate that the universe is no greater than 28 billion light years across.

  • @mystery512 That's a good point! I'm not for sure but I think I've heard that the only thing they have ever found to be faster than the speed of light was during the big bang when it initially happened.. Not sure if it stayed that fast or if it slowed down to the speed of light? So it might be even farther across than that? But I can't remember for sure so you're probably about right on..

  • Neil is sexy.

  • I have a segment suggestion: pretend your a caveman (or some ancient person) and make up answers to natural phenomenons.

  • ......Zak knows Kristina. Therefore Cassandra (Nerdz4L) probably knows Kristina. Everyone on youtube freaking knows everyone else, srsly.

  • omg the girl in the middle is super adorable.

  • What if we're already dead, and this world IS heaven, and when they say everyone gets a mansion, maybe everyone should have had a mansion but money and greed took over

  • they say that the universe expands. so, it has to have and an end.

  • Well we can't know that cause looking in our big telescopes allows us to see the past (cause of the time it takes light to reach us) so we won't be able to know how big the universe is right now, only how big it was.

  • Girls: donuts, boundaries, mobius strips, inner human nature.

    Guys: IT ENDS THAT WAY. LETS GET DONUTS!

    Yep.

  • if the universe ends.....where does it start?

  • Oh my gosh my head hurts sooooooooo bad right now! It hurt to think about the universe then look around were you are and think about how your part of it. And yeah the snow here in Seattle is ridiculous right now. But are there other crispy cream places besides the one next to Costco in Sodo? I think the QFC in the U district has top pot which is good enough for me :)

  • Omg! Morgan and Kristina in the same video! :O!!! SO awesome! :)

  • I freakin adore Morgan and Zak!!

  • @JoyMac Zach*

  • I think the universe is like the tree falling in the empty forest thing. It's infinite, but if there's no life there to observe it, does it really exist?

  • You guys should read the Flatland: A Romance of Many Dimensions. It's a satirical novel from 1884 about a man named A. Square and it's all bout topology. It won't answer your question about where the universe ends, but it'll help you better understand about things like spheres and toruses and the dementions and all that.

  • We'll never catch up with the end because the universe has been constantly expanding since the big bang...but what is it expanding into?! This topic has always blown my mind.

  • What's actually AT the end of the universe that would make it end in the first place, that's what I'm wondering. Even though I have trouble with the idea that the universe is infinite, I have infinitely MORE trouble thinking of what could possibly be there to stop it? What is there, like, some brick wall or something? But even a wall has another side so....>.<

  • I think Morgan and I have the same glasses... :D

  • At least there were no cavemen mentioned in this video. PS, the universe is INFINITE!!!

  • Comment removed

  • My astronomy class taught that the the farther you go to the edges of the universe, the farther you go back in time. So the farthest edges of the universe are still forming and expanding. I'm sure there's more to it, but the class ended a while ago and my notes are still at school.

  • We can estimate the difference because we can see near the beginning and how far away it is, giving us the approximate age, and we know how fast the outer edge goes: the speed of light.

  • @LKBM (To clarify, this is the observable universe, Neal was talking about. Space can expand faster, though.)

  • I kept wondering when a collab with Morgan would happen now that she is in Seattle. You two should definitely keep collabing. She's pretty great.

  • I can't seem to comprehend the concept of the universe NOT ending. Hmm... I think of it like a spiral. You start at the center, but you can keep it going forever.

  • i think the world ends where you die

  • the nobel prize in physics was all about this. what they said was that the universe as of right now has a place at which it is expanding. it has an end, it is just unreachable, and in fact it is expanding at an increasing rate. the universe is getting bigger and bigger at a rate that is physically inconceivable. this i think, goes along with the idea of larger and smaller infinities. the universe is expanding at an infinitely large rate. faster than we can know

  • I love the background conversation going on at the same time.

  • i tell my stories like neil, and debate like morgan.

  • three of my favorites vloggers ever together! what the... I wish be there, seriously! 

  • thats a dumb question, HATE YOURSELF! ahahahahah i love thatzak

  • Also see research entropy.

  • Professor Brian Cox, Wonders of The Universe, has your answer and explanation to the end of the Universe and the the way things work. I believe the episode is called "Time." Really, watch it.

  • anyone else notice what the tags say? =D

  • I have a question. Is everyone on this planet somehow related?

  • What they seemed to eventually conclude was what scientists actually think, but there's always the question of whether scientists are actually wrong or not.

  • Did anyone else have a flashback to the doctor who episode, don't blink?

  • current mathematicians/scientists believe the universe is a sphere, so there really isnt an end.

  • @kailinahistory8 But what's outside of the sphere?

  • the topic of existence hurts my brain, because the theory says there was a "big bang" that laid the foundations of our universe...but what makes my brain hurt is thinking what existed before the big bang and how the things that caused the big bang to happen existed and what allowed them to exist..because its really hard to think about something that people say have no beginning or end and is truley infinite

  • some of these questions are not philosophical really. They are scientific and have answers (whether or now we understand them)

  • I don't like having so many people in these, it's harder to follow when 5 people are all saying things (two of them mostly just saying annoying-ness) i liked it with just the two of you before

  • ok i know this sounds really stupidly sad but u guys look like power rangers

  • What this guy is saying is that there is always an end to the universe, but only when you look at a certain point in time. When the universe further expands into the end when does it stop expanding? Is there a specific point, and will that be the end of the universe? Or could other big bangs occur after a collapse?

  • QOTU: Alternate dimensions? Y/N?

  • what if neville was the chosen one and not harry, How different would everything be? or would it just be replaced by neville?

  • @carrlozXemiliano "Neville Longbottom and the Chamber of Secrets" does not sound like a novel appropriate for children.

  • this is absolutely brilliant

    pls upload videos of this kind with you friends

  • According to Doctor Who, there IS an end. So it must be true...... ;)

  • The universe ends at the beginning of the next universe. :] Hurray multiverse!

    Also, how does Morgan live with those two guys? I feel like those would be frustrating living circumstances. :P

    Also also, Neil is super smart, and I like like it.

    Also also also, this was one of the best QOTU's yet.

    New QOTU: Why do we love reading and discovering fiction when there's so much real life around us to discover?

  • If there is an end, and we were at the end, would we hit a wall? What would be at the end? a forcefield? the true "nothing"?

  • If you gaze into a telescope and look far away into space, you will see yourself staring right back at you.

  • Endless donuts?! I can dig it.

  • Physics predicts an end to the universe much the same way that they predicted black holes before discovering them, Super advanced mathematics are awesome like that.

  • Numbers are infinite..

  • You should make cake instead. Oh wait... that requires work. 

  • i like the lion kid.

  • Comment removed

  • Gosh...now I want doughnuts :(...But, like you Kristina, the WA snow is preventing me from going anywhere :(

  • let go to candy mountin !!

  • I love neil.

  • I like futurama's big bang theory

  • BANANANEIL!!

  • This is really strange because I was literally *just* talking to my Dad about this and I told him that the way I see it, the Universe both does and doesn't have an end at the same time. It does because it's something that is expanding, so it must have a size and, therefore, a limit. But it doesn't because it is everything, it is expanding and creating more of itself, rather than going into something else. It just *is*. I hope that made sense to people other than myself, it's hard to articulate.

  • Whoooaa I didn't recognize thatzak at all!

  • The infinity that lies within this space is a universe worth of exploration!

  • Like all philosophical journey should end, your's ended in self-awareness.

  • I agree with the boy who drinks way to much coffee!!:D

  • @iceybaby22 i win!

  • yup, kristina and morgan. it finally happened.

  • if it helps, the universe is more like a mobius strip than a sphere

  • holy crap its @morganpaigeloves

  • Shit kids say : "We'll build our own universe out of donuts"

    Shit boys say : "I have a jetpack"

    Shit girls say : "My brain switched to realizing that it's out there and it's real"

    Shit ADHD says : "Anyone want donuts ?"

    Shit guys say : "Moebius."

    Shit you say when you're high : "Think about this : we're in the universe."

    42.

  • No way no way no way! Best guests and best video ever! :D

  • I agree with Morgan @ 1:00. IMHO, it's the same thing with perfection, infinite life and God always existing. Not that I want to begin a debate on religion. Sorry.

  • We should also ask Hank...

  • I like to think of the universe having a center like the millions upon billions of galaxies and all those galaxies are revolving around that center (like a ginormous black hole or star). BUT, because it continues to expand, there’s something with greater gravitational pull on the outer edge pulling everything out from that center and expanding the universe. In turn this causes a series of events to create more and more planets, stars and etc. Yes? No?

  • Can't help it. I hear end of the universe and think about the restaurant there. And that's completely different.

  • omg, vloggers i love.

  • THATZAK O:

  • It's funny to think that somewhere out there is maybe a planet on witch some creatures are talking about the same thing

  • Theory: The universe is expanding at the speed of light, so matter can never "go beyond" the universe because matter can't travel that fast.

    That's the theory I heard that sounds most probable anyway. How "nothingness" beyond the universe, dark energy, "what" existed before the universe started expanding, ect. factors into this... I have no idea.

    So I'm with Neil on this one :P Keep doing these they are fun to watch!

  • @NomineBlack actually the hydron collider has managed to find a molecule or particle or something that can go faster than light. so in theory we could get to the end and past it in a few thousand years

  • Physics argues that the universe is finite. Not infinite.

  • ok so this is my opinion: we live in a story like in inkheart and actually the universe ends where the writer of our story stopped writing about it and there are like 1000s of universes out there just cause of stories and our stories are in books at the source of some enormous force and that's it!

  • AH, people I like! 

  • Neil is correct; Technically space doesn't have to end but the part of it that has anything in it most certainly does. It started all together and some billions of years ago began expanding, so it the end will be how far the fasted object got in each direction. In terms of how scientists can tell; as he pointed out they can use telescopes to see into the past. the new one they're building will be able to see several billion years into the past when things weren't so far apart.

  • In Bill Bryson's book A Short History of Nearly Everything, he describes it in a way that makes a lot of sense to me. Like you were saying before, if you kept walking farther and farther into the universe, you would eventually end up where you started because it wraps around. But it's not a circle. It's more like if you put a man who had lived his entire life in a 2 dimensional world on earth and told him to walk around it, he wouldn't be able to conceive how he ended up where he started.

  • I seriously was like "wait I'm pretty sure I clicked on a Kristina video, not a Morgan one" but now this incredibly awesome now. Not that it isn't usually.

  • MORGAN!!!!!!

  • there is an end, the end just changes constantly because the universe is continuously expanding. so technically there is an end, but for all intents and purposes there isn't. like we will never be able to go to the end of the universe.

  • i feel like liz got ignored. i love liz.

  • @ellencradd10 So do I, she was all the way in the back!

  • donnie darko told me parallel universes are cooler anyways

  • I think the universe dose have an end, however we just don't know where exactly because the universe is continuously expanding then that point is always indefinite. If the universe were to stop expanding than...that would mean something has gone terribly wrong in the center of the universe and to our human knowledge there is nothing outside of the universe, so technically the universe doesn't have an end because there is nothing to say the end of the universe. (I really hope that made sense lol)

  • "Our whole universe was in a hot dense state, then fourteen billion years ago expansion started...wait"

  • @GriffithAMPS The earth began to cool, the autotrophs began to drool.

  • MIND BLOWING FACT OF THE DAY:

    The main ingredient of atoms is nothing. Roughly 98% of an atom is nothing.

  • QOTU - What is nothingness?

  • If the universe is infinite than it is expanding into itself.

  • @Litheran nonsense. some infinities are larger than others

  • @CatalunaLilith Poppycock; infinity excludes the option of there being any more. Infinity has no end; therefore nothing is larger. Unless that's a reference I'm not getting?

  • @Litheran thats not mathematically true; in calculus and most precise applied mathematics different infinities lead to very different results. A slight expansion on a basic example, like John Green explained in The Fault in Our Stars (which would be the reason why you see the phrase "some infinities are larger than others" so much lately) is that...

  • @Litheran ...between the numbers 1 and 2 there is an infinite amount of numbers, like 1.1, 1.11, 1.111, 1.111, 1.2, 1.20000009. But there is also an infinite set of numbers between 2 and 3. so there are twice the infinite set of numbers between 1 and 3. Thus, some infinities are larger than others

  • @CatalunaLilith But it is the value of the integer which is larger; not the amount of permutations or repeating decimals. If we look at the numbers 1 and 2 as separate universes; both would still stretch out without bounds or end meaning that neither has greater scope over the other. In this case the integers serve as titles for two separate infinities, not amounts.

    P.S. Know that I see this as good clean scientific debate and dissection, not a youtube derp battle.

    = )

  • @Litheran The Universe is not infinite. Space is infinite. The Universe is expanding.

  • @Litheran (At least, as far as we know, Space is infinite)

  • NEIL. Hey I know him.

  • it has to be expanding into something......

    but of course everything could be just a dream, and we are all tripping at the same time - 'time' of course is a manmade thing

    but why waste time on the big universe when we coulde be making big love

    :D

  • I'm a physicist and I answered this in the comments last time! What Morgan said near the start was completely right, there is no 'end' because the universe isn't expanding into anything, there's no point which is outside the universe. Just because it doesn't end doesn't mean it's infinite though. I am loving how much awesome is filling my screen right now

  • Do you mean "end" as in either end of a yardstick; or do you mean the antonym of "begin" ?

  • Oh, and one more thing, something shaped like a doughnut or an inner-tube in space or geometry is called a "torus."

  • 93 billion light years is the estimate on the diameter of the observable universe. You guys know wikipedia is back up right?

  • @IwanttoliveinParis

    " estimate " "observable universe"

    Mastermind 2012

    "Your name please"

    "IwanttoliveinParis "

    "And you chosen specialised subject?"

    "Pointing out the bloody obvious"

  • Zak is so deep.

  • @girlsknow Zach*

  • Scientists are now postulating that we are part if a multi-verse, that our universe is not the only one. They also speculate that its possible the laws of physics we know, may be different in different universes too. So our universe may have an end, or outer limit. What's beyond that may be other universes.

  • SO THIS IS WHAT IT'S LIKE WHEN WORLDS COLLIDE

  • The current thinking is that the universe is not expanding into "nothing." The "...and what's beyond that" line of thought is not needed. There is no nothing, no infinity of emptiness beyond the 13.7 billion light years we're dealing with. Hope that helps with anyone's " cosmophobia.

  • These videos remind me of what Ravenclaws would do every night in the common room :)

  • If this group happens again, please try to have it so Neil is in the frame :)

  • @Virini He was. He chose to keep ducking out.

  • Under 100 club!

  • i only recognise banananeil, kristina and her friend :/ haha

  • zack where is cassi

  • @frenchpeopleonice In Canada.

  • this might be dumb, but I can't wrap my head around there being an end to the universe because I can't imagine what would happen once you do reach the end. Is there a state line, and beyond that is krispiverse? Does one just stop existing once you go beyond the universe? It just feels kind of weird trying to imagine what happens if you do reach an end of the universe.

  • Maybe the universe IS infinite- an infinite donut, that is.

  • Neil "Lawyer-ed" you all in the end. haha

  • How many licks does it take to get to the center of a tootsie pop?

  • Fourth!

  • It ends where my brain starts to hurt thinking about it.

  • Sorry had to.. It ends where I want it to end. 

  • First!
