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.. . .

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.

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.

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.

So would there be particles that are quantumly entangled to those other worlds from their base state?

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?

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.

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?

Of course you can interact with them!

thus proving concepts of alternate realities or “dimenshions”

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.

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. .

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.

If you could travel at light speed what events could you witness?

Just call it supernatural and quit chasing your tail

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.

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?

@Sphere723

Ай бұрын

He's facilitated several debates on the topic.

Are two games running on the same computer seperated by space? That is how I conceptualize is somewhat.

They exist beyond the fabric of spacetime, in the quantum realm.

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.

Devs was wild

The ‘equations’ make it indisputable. How can we say this is more than simply a theory??

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.

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?

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.

wtf does 'make a measurement' mean

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.

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.

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).

Like i went down a difficulty level in a videogame. The logical part of me figures it's just my fundamental perspective that changed.
