My Blog has an excellent graph of it. votedavedowling.wordpress.com/2018/10/09/space-time/ There is an infinite number of Big Bang cycles. As Energy is never destroyed or created AND nor is absolute zero a temperature ever reached. IMO there is only 3 places The other big bang cycles are. Either right here and unobservable due to Truths we have not yet discovered OR Outside of this Universe OR they are the other Galaxies in our Universe.. . .
Sean: "Present does not exist."
Also Sean: "Many worlds exists simultaneously with our world."
I didn't watch the full interview because it was too long. Instead, I am watching every single clip. Carroll is so interesting and good at explaining complicated physics.
Equations have me winning the Powerball but I can't see the money.
Powerball is the best bait for time travelers.
But doesn’t one Marco see the money?
@@terryh1451 I’m starting to see it come way now.
3:07 I experience it cutting my hair with a 3-way mirror and a full length mirror behind me and then I use the multiplier effect from Charles duggan and geometry from multiple perspectives create my formation.
Carroll, Greene, Sagan, Cox, Randall are all amazing explainers of this kinda stuff.
If you haven't seen David Deutsch (the "father of quantum computation") before, definitely check him out. I regard him as one of the best among all of these guys. He's completely on board with the Everettian approach to QM and argues for it with a strength beyond what Carroll has ever done.
So would there be particles that are quantumly entangled to those other worlds from their base state?
Is anybody here familiar with kripke? I stumbled into a class on him (and a little bit of frege/russell) and possible worlds philosophy/logic. Is there a good amount of useful interchange here?
thus proving concepts of alternate realities or “dimenshions”
I don’t get it if it’s either a fine tuned universe with precise conditions that could only occur in a one in a trillion chance to create life here on earth or it’s a multiverse where those conditions just happened by chance because there are infinite universes like throwing a bunch of scrap metal into a bowl and poring out a car engine then how could those same conditions happen in those said parallel universes for alternate versions of people to develop in them?
They are a mathematical device.
A way of summing multiple dimensional spaces.
A mathematical drive. Like calculus.
Why don't we think of time as compactified, since calculus relies in this idea?
It likely is. This is why there are energy limits. And why there is conservation. .
If you could travel at light speed what events could you witness?
The big bang is only one local clock. That isn't multi-universes; rather one event of untold number that no-one will ever know. Multi-worlds is a fantasy based on mathematical machinations that emanates from particle to particle interactions. Wrong page. Law of conservation of Energy dominates; not, law of conservation of mass. Schrodinger's analysis is being misunderstood. The electron has no mass in my theory. It is photonic energy that's mailable to Qe interactions that displace a stronger quantum field density.
Of course you can interact with them!
Maybe we are entangled with them in every moment and interaction
yes, we are. but that entanglement gets very weak very fast. decoherence is the normal thing to happen most of the time
@@yonaoisme Did you see that original Twilight Zone episode ?
It's just a description of infinity - always in all ways. Every possible choice, every possible outcome, with each new "world" just another frame in a never ending movie.
Where is our own materialistic universe when at a deeper level there is nothing,
perhaps some wavelike entities. Why couldn't other universes also rise from that level.
"No extra baggage"??? It is the picture with the most baggage!
Depends are what you're trying to minimize. Many worlds is mathematically very simple. The schroedinger equation describes everything. Other theories are schroedinger plus something else.
I am thinking that he is saying it is simpler than alternatives such as the pilot wave theory approach of de Broglie/ Bohm.
wtf does 'make a measurement' mean
Are two games running on the same computer seperated by space? That is how I conceptualize is somewhat.
Personally I'm not a fan of this particular flavor of multi-world interpretation. I do of course however consider it a possibility. I think one concern some people have with this kind of idea, is that if everything happens then what's the purpose of science or asking anything for the matter. And I think one thing that is easy to overlook, is that the space of all possible physically realizable states is not the same thing as the space of all states that we could imagine, and of that space of possible states, vast regions will be unstable or incoherent and without structure. Furthermore the causal relationships between the stable and coherent worlds of which we are familiar would emerge from underlying topology of the space of all possible realities. This topology would have structure and that structure would be worthy of question and study. But again I don't even strongly believe this kind of multi-world interpretation.
They exist beyond the fabric of spacetime, in the quantum realm.
There's something unassuming and confident about Sean Carroll's voice that makes me believe him... but many worlds seems so wrong to me but I feel totally inadequate in arguing so.
Are there some videos of Sean Carroll in debates with some other smart scientists having different points of view on this?
He's facilitated several debates on the topic.
Devs was wild
Is the many worlds interpretation of quantum mechanics a challenge to science itself? I mean, previously our scientific theories were grounded in observation and experimentation to confim or deny those theories. If we now have a theory of how the world works, that even in principle, can not be verified by observation or experiment, is this theory, in our case the many worlds interpretation, can it really be called science?
thats like asking when Einstein was figuring out GR, was that science? Science is the process of figuring it out. Not just the conclusion of the experiments and data figured out
you have to rearn what it means for a theory to be tested. in a naive way of thinking, none of us has ever "seen" nuclear fusion, yet we know for a fact that the sun does it. in the same way, nobody can "see" all the branches
@@yonaoisme In a nuclear fusion reaction there are observables that can be measured. In a many world interpretation, there are no observables because what we want to measure is completely cut off from our universe. Quite an important distinction.
@@TactileTherapy GR has actual observable data backing it up and it makes testable predictions. No comparison with many worlds!
@@ricomajestic Im talking about before it was testable. Its not NOT SCIENCE before its testable stage. Thats my point. Einstein had to wait until there was a solar esclipse to test GR. But he was still conducting SCIENCE
As someone who knows nothing about physics and math, my comment means nothing.. but I always wonder when data or math point towards things such as many worlds, I wonder if maybe it’s getting into an area of life that is beyond our limitation. Sort of like a being in 2D trying to comprehend and understand 3D. Maybe their data would suggest something weird and crazy, but it’s really just data within the limitation of 2D trying to make sense of a dimension beyond what can be comprehended. There is data, but it’s just illuminating a fraction of something unfathomable to us.
Very interesting. But there is a conceptual systematic mistake imho.
Why should we take the Schroedinger Equation seriously? Let's think about that.
Because the Schroedinger equation accurately describes phenomena that can be observed.
Really, there is no other reason to take the Schroedinger Equation (or any other scientific theory btw ) seriously.
Not because they are fascinating and complex mathematics. Not because a genius wrote them. Not because they might instinctively compelling.
The only reason to take any scientific theory seriously is because it WORKS and we can CHECK that it works. Because there are data and observations to back it up. Because there is a correspondence between observed reality and its theoretical description.
The many worlds framework, by definition and by admissions of its proponents themselves, is unobservable, unaccessible.
Therefore, for the very same reason the Schroedinger Equation should be taken seriously, the Many Worlds Interpretation cannot be taken seriously.
If by taking something seriously we arrive at something that cannot be taken seriously, perhaps we are not "taking it" in the right way.
I wonder if humans can find a way to further substantiate the Many Worlds Theory. It's interesting, but it's probably the most "out there" theory that can be tough for even science lovers to take literally.
Infinite space does not imply infinite matter.
The mental image of many worlds is doable if you are a comic book fan. Shout out to Grant Morrison.
Didn't know who this dude was. Maybe you're right and he did some good writing using these ideas. His Wikipedia article should make most people want to throw up with how dumb they make him sound.
The ‘equations’ make it indisputable. How can we say this is more than simply a theory??
Just call it supernatural and quit chasing your tail
Carroll's cadence is super annoying but not as annoying as his reasoning to support his beliefs. His idea that dark matter must be a particle and the multiverse is reality because ... math (one specific math that is purely theoretical). It's astonishingly bereft of honesty.
Sean has to be the best teacher... He's amazing.
Car
Thinking of a conservative mindset as an "impulse" is fascinating.
Sean and Lex seem like separate spaces but they are one space therefore the present can't be divided but the present by always playing separation knows it always exist(proof of being present). Eternity(present, now) can't exist without knowing it exist because this comment is proof that existence and the knowledge of one's own existence is eternal. Eternity therefore always first believes it exist(plays as an origin) to know that it always exist by always first believing it exist, the Universe is a reproductive state( the Universe never changes including always first believing it may always be changing).
I wanna live in a world where everyone poops their pants…
Be the change you want to see in the world.
You’re about to by state of the opioid epidemic
Move to Los Angeles
Biden is leading us to that world, with every b0wel movement that he has...
I'm doing my part.
Nonsense
So, i've had the experience of "changing" dimensions. 5 years ago I did DMT in an alternate but very similar world where i was suicidally depressed because it was so hard, and I landed here, where everything is almost the same, but EVERYTHING is easier. Like i went down a difficulty level in a videogame.
The logical part of me figures it's just my fundamental perspective that changed. But the part of me that experienced it really feels like i traveled dimensions and landed in an alternate one.
your dmt experience has nothing to do with the many worlds
@yonaoisme your chicken sandwich has nothing to do with the jelly bean castle beyond the sewing machine museum.
It's amazing that there are infinite copies of me and they all make better decisions than the me I currently inhabit. 😒
It's certainly possible that you (or anyone, including myself) are the worst version of yourself to exist across all possible "universes" or "worlds" in this sense. A horrifying prospect lmao.
Prove it kvnt
They don't necessarily have to be parallel, but rather a cluster of black holes structured by gravitational force, which, like all galaxies in this universe, converge towards a large attractor.
no. that's precisely not what we are talking about here. you just watched too many mivhio kaku brainrot videos where they show pictures of colored bubbles as the "multiverse"
@@yonaoisme The misunderstanding here may be with the word parallel, if there were other universes they could also collide, just as black holes can merge with each other.
@@Nickname_42 no. those universes are indeed almost parallel, interference happens rarely
@@yonaoisme As you know, you cannot know.
the equations show a thing I can't describe 🧐 that's not great science
describe the curvature of spacetime without mentioning einstein's equation.
I'm beginning to strongly doubt that the more we get to know the world, the better it will be for us humans. Above a certain limit, the opposite is likely to happen.
that's just wrong. through all of human history the opposite was the case, and there is no reason to think it could be otherwise.
@@yonaoismeno you’re wrong, would you rather have been born back in the 1500s? Things have gotten better or humans. You’re basically saying we are better off ignorant. Which is insane.
@@user-xr7fi6dy1w i was saying the exact opposite my guy. they person i replied to said that knowledge is bad for us.
@@yonaoisme ah sorry my dude. Little high 😂😂 ok then my comment applies to the idiot who made the original comment. My bad 👊
One step away from calling humans a parasite on the earth. Take another step and you're salivating over the genocide of maybe the most intelligent organisms to exist in this galaxy, at least. Get some perspective and stop with the self flagellation. David Deutsch is a cool guy to check out if you want to snap out of it.
I feel like our civilization has slipped into an alternate timeline more than once. Or it's a game theory reality and we're moved like pawns.
So this guy has no problem believing that an infinite number of universes come into existence every moment, but believing in a god is too much for him.
Math is just a tool. Existence takes primacy over our tools to understand it.
0:44 Alice in wonderland - but through the looking glass -1 because 🐇🍄🐛⏳ I only have 10 years barring any unforeseen consequences
obvious nonsense from people who do math all day but never go outside.
nos espera otras dos horas de "periodistas" rebuznando sobre la moral, la ética y las buenas costumbres, sobre adjetivos, etiquetas y lo que "debería hacer", dándonos lecciones de moralina sin nada de lo que es la Gestión Deportiva, análisis de data deportiva para la toma de decisiones en un club, rendimiento de jugadores, táctica...nada de eso, todo chisme y lloros
Funny, sounds religious. Have we finally circled back on ourselves?
For me, an infinite universe vs. a singular one produced by the big bang has nothing to do with religion, but either could be inspired by it. The main dude credited with the modern big bang theory was a Catholic priest.
Mr Carroll doesn’t believe in consciousness existing outside mind, but believes whole worlds exist outside of space, because the equations show it 😀🤦🏼♂️
I love how people that aren't even close to earning the right to call themselves an astrophysicist can call out an astrophysicist 😂
just admit that your religious dogma clashes with reality and your cognitive dissonance is off the charts
Are there equations that show consciousness exists outside the mind?
@@theshillpill6937 there aren't even explanations of what consciousness is.
@yonaoisme consciousness, is you literally collapsing the wave function of current running through your grey matter...
Bunch of nonsense !
There's no any evidence for parallel universes whatsoever.
Another typical edgy nerds who think the world is just random matter .
what is the evidence for black holes? have you seen one?
@@yonaoisme your ass is my evidence.
@@yonaoisme Yes! We see how all the things around the black hole are behaving exactly as predicted by GR! We see the light from distance stars bend exactly how predicted by GR.
Not sure what you're getting at but I feel like you never solved a single differential equation in your life. And yes, they are practical and engineers use them all the time to build shit, not just "typical edgy nerds"
Where are the parallel universes? …in Sean Carroll’s imagination!
😂
you're 50 levels of understanding away feom getting it
😂😂😂
😂😂😂
Perhaps, but what the hell is the product of your imagination? Dirac guessed the form of equations that described how fundamental particles interact at times. That's imagination.
