I cried watching this video so many damn times, still one of my all time favorites, the calm acceptance of all possible futures is a really good thing to learn and keep
Most of the early events on the timeline are an “assumption of likelihood,” rather than an “assumption of occurrence.” The major asteroid impact, for example, is likely to occur within the next 150 million years (it could be sooner). Not that it will occur in 150 million years. At least that’s how I understand this video.
You didn't understand the last line of the video. When it says TIME BECOMES MEANINGLESS it means that you don't have nothing to measure CHANGE hence the phrase Time becomes meaningless, truly a very profound phrase.
One of my favorite things is seeing people react to melodysheep's content. On the subject of the multiverse, I believe in two kinds primarily. I believe that one, there are definitely other universes out there. Whether it's the brane universes that string theory describes, or the many worlds interpretation of quantum mechanics, the basic multiverse idea that our observable universe is just a little patch of one single great big cosmos that's infinitely large, or the inflaton field theory that entire bubble universes hyper inflate from the inflaton field and because the inflaton field is itself in a constant state of hyperinflation, no matter how close two bubbles are when they are created they will never intersect. I think it's equally likely that it could be any one of these or any combination of them. There isn't one that dazzles me over the others so I'm good with any of them, though I do suppose I fancy myself the inflaton field theory.
There is a nother kind and I suppose you could call it a multiverse. As far as we know, everything is a quantum mechanical system. Even the universe as a whole is just one giant quantum mechanical system. This means that the universe itself probably exists in a state of superposition, a quantum state of all possible states. Observation and local entanglement cause aspects of what is called the wave function to collapse, whereby eliminating possible states, as well as bringing into existence the possibility of new states that were quite literally not possible before. Because it's impossible to measure/observe a quantum system in full as described by the uncertainty principle, and we are not just conscious beings but ones that can devise ways of making the most precise measurements, I believe that free will is actually real. Because we ourselves, and our brains are quantum mechanical systems, and consciousness happens inside our brains as well as what we would call free will, I think that thing we call free will, that thing we call choice, whatever it is, is an emergent quantum process, by which we (or in other words the universe because we are just part of the self that is the whole universe) utilize to collapse parts of the wavefunction so that the universe can maintain the parameters of the uncertainty principle.
When we make what we call choices, we cause a collapse of the wave function locally, maintaining the parameter that the entirety of the wave function cannot be observed, and destroying and creating new states within the superposition of the universe, that we interpret as different paths. If we come to a fork in the roads and go left, we inexorably destroy the entirety of the aspects of the wave function, in which we went down the right. At the same time, we create the future possibility that we come back from going left and turn right. We can't go down both, not because we can't be in two places at once, though that is a emergent quality of how we experience well, our experience. No we can't go down both because that would lead to an observation of the wave function in its entirety. If we could go down and see both paths in the fork in the road, that would mean we could do the same everywhere else. It means we could go to work riding our bike, driving the car, and walking simultaneously, which the universe by it's very nature prohibits. So in order to maintain that we can't go down all paths, the universe emerged a quality in living, conscious, sentient, sapient beings - a quality we call choice.
I know this went from being about the multiverse to being about free will too but - it's an interesting thought at least!
You didn't recognize Stephen Hawkin's voice - you recognized his speech synthesizer 😜
(which by the way had the voice of the developer of the speech synthesizer who died shortly after developing it. Stephen hawking wanted to keep his voice to honor his memory)
Well that's incredibly sweet and I'm glad I know it now.
@@laurencole2937 Yeah. Stephen Hawkin was from the UK so he spoke with a British accent back when he could still speak. He was at one time offered an updated more modern and realistic sounding speech synthesizer but refused because he wanted to keep the guy's memory alive. Besides, the voice had become so recognizeable at that point already.
@@Hairysteed After years of use, it probably also had become "his" voice in a way. I think it would have felt very off putting to suddenly sound different, even if it was a synthesizer and not ones actual voice.
4:19 Back in the times of Ancient Egypt, they had different constellations than we do, but the stars were, as a general rule, in their same physical location in space. It takes stellar timescales for stellar drift to occur, where constellations would PHYSICALLY change.
Oh. I see. That makes sense.
Constellations are all just made up anyway
8:15 And to answer your question, that is Neil Degrasse Tyson voicing one of T.S. Elliot's quotes.
_"They think the Voyager is gonna be out there"_ - Well, of course it's gonna be out there. It's not coming back, is it? And it's not just going to poof out of existence! 😜
I guess I was thinking it would like...crash eventually. Or get crashed into. Or get sucked into a star or black hole or something.
@@laurencole2937 There isn't anything to crash into between our solar system and the nearest stars. Interstellar space is _very_ empty.
Remember, the text said _"Voyager passes nearby star"_ meaning it will have crossed the emptiness between us and the nearby stars.
@@Hairysteed well there are asteroids and stuff yeah? We get meteor showers often enough. 🤷🏼♀️ Or like, a planet that sucks it into it's gravitational pull. Something like that.
@@laurencole2937 Possibly, but the chances of it running into something are pretty low. Within that "short" of a timeline, it's pretty unlikely
@@indmur gotcha, gotcha. Thanks!
Anthopocene era = age of humans
Time becoming meaningless has a decidedly scientific meaning here. One also can say that it stops existing. All usable energy is used up, everything left is massless and timeless particles, ans as said, nothing is happening and nothing keeps happening forever.
Patreons please ask for more of this x'd
To elaborate on Hawking Radiation: it isn't just one particle that falls in it is actually the antiparticle part that falls in. Since antiparticles have a negative mass, it decreases the structure of black holes.
Antiparticles do not have negative mass, they just have opposite electrical charge to their counterpart. No proven matter/antimatter in existence has negative mass. Anti-protons have negative charge and anti-electrons have positive charge, that's it.
In fact, antimatter particles have the exact same mass as their matter counterparts.
Antimatter also isn't anything otherworldly or special, Positrons (Anti-electrons, or the equivalents of electrons but with a positive charge) are frequently used in hospital scanning machines, and are literally emitted by fruits like bananas.
Uhm, I believe you misunderstand something there. Antiparticles do not have negative mass. Overally, from what we can tell, outside of just having an opposite charge, they act the same way as normal particles. Anti hydrogen acts just like normal hydrogen, with the difference that it´s made from an anti-proton and a positron. They just have mass like everything else, because mass isn´t conected to charge, but the energy that it´s made up from. Because in a roundabout way, energy is mass.
Hawking radiation actually works by a "simple mechnism", and thats "in a roundabout way" the fact that you cannot create something from nothing. The vacuum is actually not a vacuum at all, but always "boiling" with energy that makes random particle/antiparticle pairs pop up and instantly anihilite each other again. But that energy isn´t usable, it´s just there. But when this happens close to the event horizon of a black hole, under the right conditions one of the pair can "fall into" the black hole (pass the event horizon) while the other does not. But you cannot make make something from nothing, in this case create a sustainable non-virtual (virtual particles is what we call these random particles popping up and annihilating again) particle without puting energy into it to "make it real". So the energy has to come from somewhere where usable energy is available, and that "where" is the black hole. It´s an unbelievable tiny amount, a snowlfake hitting the ground is a nuclear detonation to it, like a nuclear detonation is to the snowflake hitting the ground. But over unimaginable long times, it will whittle away at the black hole, a death by a thousand papercuts so to speak.
It's negative energy, not negative mass. Besides that, it's nice to finally see someone mention this important point.
Black holes delete the information that indicates if a particle is an antiparticle or not. The black hole would just lose charge and gain mass if we throw antimatter at it
@@JoinMoonSucks source?
In terms of multiverse..i always liked the ending scene of Man in Black 1..when it zooms out until our universe is just a marble an alien plays with. From that point you could keep on zooming out. Had that thought already as kid kinda..when you look at an ant, its small. If you are the ant, what is "small as an ant" for you then..smaller and smaller..whats the atom of an atom. And then ofc backwards, maybe we are just "bakteria" inside the body of another living organism..we cant know.
This video has to be one of the most profound meanings of life I’ve ever seen.
The asteroid stuff was estimates based on how likely those events will be over a given period of time. He’s not saying a specific asteroid is striking that year.
2:00: "2019. 2020." Good that you stopped counting there, you would have run out of stamina real fast :D
I always wanna believe Middle-Earth is real bc Tolkien's world is just too amazing to not live in. BUTTTT then I remember that a world like that is just as ridiculously unplausible as the worlds in Genshin Impact or Street Fighter and I get sad lol
Literally this woman says that she thinks everyone is guilty until proven innocent. That's how backwards her critical thinking skills are. Holy heck.
Life is a gift, we are all miracles. Our Earth, our home, everything on it. Is a miracle.
💯💯💯
Does she not think voyeur won't be around in a couple thousand years?
Colliding brown dwarfs can not become new stars. Yes, they will shine very bright for a few years maybe but they do not contain any more hydrogen to ignite cold fusion again, its basically mostly iron that gets extremely hot because of the impact but will cool down in a very short amount of time.
What are you on about? "Not containing more hydrogen"? Obviously if they merge the resulting body will have more hydrogen than the singluar seperate bodys had. Namely it will have about the mass of both combined. And if thats enougth it WILL ignite the fusion reaction. And what BS about cold fusion are you blabbing? A star does hot fusion, you know, by having enogh heat and pressure to cause a fusion reaction. Cold fusion is a theoretical idea that so far science thinks is unlikely to actually exist or even be possible in the first place.
You’re thinking of Black Dwarves, the end state of White Dwarves that are basically just big balls of iron. Brown Dwarves are failed stars(mainly hydrogen and helium), so they very much can form stars if they collide with each other.
OKay im just gonna mention this, it keeps continuing going faster and doesnt stop, so the supervolcano probably didnt actually last that long, it just kept it on the screen cause nothing else was really happening in that time. Thats my guess.
the reason it takes a while for some stuff like the asteroid is taking 100s of thousands of years is because they dont know exactly when it will happen. they predict its going to be around this time so thats why its a long time per event
4:26 yeah were do you think its going like it wont rust in space
videos like this always make me cry, again and again. it always makes me question why people fight over anything. looking up to the stars and even grasping the tiniest understanding of the universe reveals how insignificant i am, you are, we all are. our lovely little planet, our solar system, our galaxy, it is so incredibly tiny compared to everything out there
my conclusion: more love, less hate; we are all sitting in the same boat. a boat called "earth", "galaxy" or "universe"
Fight is inherent part of the nature. Gravity vs fusion. Light vs dark. Fungi vs bacteria. We are also the product of this universe, it is natural what we do. In the end we are extinct or settle among the stars no thing in between
hell, i know more of astronomy at 9...
I did a comment to help big glooby in this 2
Love your reaction, pls react to Life Beyond series
ermmm actually time has meaning because stuff exists and is changing, therefore time has to exist and have meaning in order to measure that thing. Though once their is little stuff and the remaining particles are simply just existing and not changing anymore. Then time becomes meaningless
Yep within an empty universe time has no meaning.
I imagine being some ultra far future human (we wouldn’t even be human at that point), looking back from my portal to a new universe, watching the last black hole decay away, leaving my old universe behind.
It's kind of sad to think that everything we've achieved in this universe, since the beginning of time to the present day, will be destroyed and forgotten about for the rest of eternity. Civilization, society, culture and knowledge, which people have strived for thousands of years to create and improve, will be wiped off the face of the universe.
It´s sad, but I find the thought also kind of calming. Nothing last´s forever, and everything ends. Even the universe itself. And at some far future point death is going to put the chairs on the tables, turn out the lights and lock the universe.
There's a new video by Melodysheep called "The Human Future: A Case for Optimism" and it touches on some great possibilities for our future. It's an excellent video and may help with that existential dread you're having now.
Doctor Who episode I think you’re thinking of is The Big Bang series 5 episode 13, or The End of the World series 1 episode 2.
On escaping the universe: that would be Rise of the Cybermen, and The Age of Steel.
The magnetic pole shifts are scientific fact, actually! It's fascinating.
They're happening now, I hear! Just read an article and a scientific paper about that, it's so cool
@@ChronicaErysWell, they're preparing "now". I've also read that a few years ago. But what are a few years in geologic timescales? It can happen anywhere from now to thousands years away. Both would be within seconds for the planet. All depends on the specific details of the processes happening deep beneath our feet, that we don't have much of a grasp on.
3:06 no, core didn’t stop here is the story
Few decades ago scientists discovered that core rotates 0.01% faster that the rest of planet, they named it super rotation
Chinese researches this year made other measures and figured that either einriss data was incorrect or super rotation of the core stoped and now it’s synced with planet
Media missed few words there
This reminds me of Dan Dennett’s book (who recently died) book “From Bacteria To Bach And Back”.
In Ancient Greece, Anaximander suggested “apeiron” considering how big the universe must be. The Greek word of “apeiron” basically means “without beginning or end”, suggesting that the universe must be boundless. Without a “creation”, always being there. This makes infinitely more sense than “creation”. So I don’t think that the so called “big bang” was the “beginning” of “everything”. In other words limitless or infinite. No beginning and no end, but instead, permanent evolution. This makes perfect sense to me. Since things do exist, there must be no bound or limit to existence itself. Life as we understand as humans, or at least all conscious life, may permanently end, but I don’t think the universe will ever end, regardless of its state and condition. Coldness & darkness or otherwise. I wouldn’t at all mind remaining dead forever. The dead don’t suffer a thing. The living do. So you can relax and sing “La la laaaa we’re all gonna die eventuallyyyy, la la laaa , and that’ll be it for us lallallaaaa 🎶 “
So I think the universe itself is exempt from time. And the universe is vastly more exciting, astonishing, wonderous, splendid, fascinating, vastly richer and greater than any so called creation myth. And unlike those myths and characters in them, the universe is actually real as well as observable.
Millions, tens millions, hundred millions, billions, tens billions, hundred billions, trillions, ten trillions, hundred trillions, quadrillions…and so on….
As of the multiverse theory, I personally don’t believe in it. Because it raises the question of what is between universes! And then what is beyond THAT! I think or believe there’s one infinite universe and no such thing as “beyond”.
Finishing note: I like your humorous, light hearted, energetic, fun loving, no drama and no bullshit reaction. You may be the only such one on RUclips. Others are such melodramatic crybabies and self proclaimed, lecturing, preaching know betters or know it alls.
What they're saying about black hole 'sounds' is that the fabric of reality is vibrating in a similar way that air vibrates when you hear a sound. You probably could hear it, but getting close enough to do so would almost certainly be fatal--I really doubt you could survive the kind of distortion that would make reality itself vibrate your eardrums.
Voyager will still be out there for god knows how long until it hits something
"If", not until. And considering how vast space is, it probably will be drifing through space long after the last star has burned up.
THe likelyhood of it ever hitting anything is unbelievably low. So with a very high likelyhood, we managed to create one thing that will be there long after we have gone. Even if we manage to last for billions of years.
@@theexchipmunkit means that even if we are gone, humanity can still be found.
@@Wet_Fungus If you can find it. It´s very, very insignificantly small after all. Drifting through interstellar space. But in theroy? Yeah. But it would degrade over time, so while it would be recognisable as something made, very little would be discernable from it after long enough time.
I dont think there will be another big bang within our universe because for one to occur you need empty space. Yet our "empty" universe wouldnt really be empty, it will still have the dark matter and time within it
We also have machines that detect the vibrations and stretching and effects of black holes on space time. Equally scientific fact as the magnetic pole shifts are.
I love melodysheep's vids. This is one of my favs, makes us feel tiny. Especially since I believe in the heat death hypothesis rather than the "big crunch" etc. Another person I follow, Matt O'Dowd from PBS Space Time has a great Heat Death t-shirt lol. One interesting thing I wish melody would touch on, semi-related to anomalies in earth besides the magnetic field flipping is the great gravitational anomaly we have. I love when we find out things we never would have expected. The fact that melodysheep uses quotes from prominent astrophysicists like NDT and Brian Greene is awesome. Big Greene fan as he's so passionate about his presentations.
I like the part where I heard noise better.
8:10 it was neal tyson saying it, but yes t.s elliot who wrote it.
Hey it's the Chicaco Reacts bartender girl!
Indeed it is
I need to watch this on my big tv.
Drinking fiji water?
Where VOYAGER 1 at? :D
Probably still drifing through space long after the last star burned up.
Well I was just about to rant on Patreon why you did not watch it on the channel, to just discover that there is this second channel where you watched 4 months ago 🥲
glad you found it!
