So, you're also a violin string theorist? :)

Perimeter Institute is a very special place ❤.

This little guy gave not the answer about dark matter. He is taking way too much

The cycles do suggest that entanglement is antimatter 's revenge. Anyhow-great lecture. Thank you.

Beautiful

I’d love to chat with this legend one day about his opinion on many worlds being the combinatorial options randomly dispersed throughout the non observed universe and not some extra dimension mess some people think. That and the whole scope of energization that isn’t on the geodesic between most observers and an event and the energy also sent back from their event to the event as an observer. About 94% 🧐

Pretty cool. My favorite violin piece is Beethoven’s Romance No.2 in F Major. There is a ‘random precision’ quality to it. A quality of which may relate to the study of quantum matter and the attempt to control a systemless system. Such systems are going to have so many cool use case basis, and a lawyer like myself is looking forward to deriving from their fundamental logic and structuring their eventual widespread integration.

Pointless.

Why is the comments filled by ignorance and insolent?

Steve Jobss loll

The level of mutual respect and admiration among us is a beautiful thing to witness, creating a safe space for open and honest conversation.👄

Thank you for having me I enjoy being here with all of y'all today and I believe it will be the Big show for everyone very soon we will see what life can really be

Making some sense of what this expansion means is something that's been bugging me (non-scientist) for a long time. I ran into very few popular science attempts to touch on the fundamental nature of spacetime in depth. Our universe's expansion is one of the few topics that's closely related. 12 years ago, a very interesting lecture was published on this channel (YT video name: "Fay Dowker Public Lecture - Spacetime Atoms and the Unity of Physics (Perimeter Public Lecture)" that I feel was a little better than most in touching on the subject. Basically we have two very distinct possibilities: A. Spacetime is fundamentally discreet (i.e. quantified) at an unimaginably small scale (e.g. Planck length). This would mean we can talk about spacetime atoms. The hard consequence is we're fundamentally blocked from knowing much at all about what's "in-between" these atoms as what happens there is outside our universe (or perhaps better said, it's outside the 3+1 dimensions we're aware of). In quantified spacetime there are extremely tricky questions to answer about what we now call fundamental particles. Are these particles always bound to just one spacetime atom or can they spread across more than one? Very likely they are spread across more than one which directly contests their fundamental nature. So in quantified spacetime, what we now call fundamental particles are most likely not fundamental. There are likely smaller things, which we may never even be able to probe individually, which are bound to one spacetime atom at a time. Another wonderful question immediately arises: Can fundamental particles travel and/or interact across spacetime atoms that are not apparently adjacent in our 3+1 dimensions? Very likely the answer is again yes, which again has massive consequences. It means the topology of our universe is necessarily one with multiple dimensions, some of which enable these "at a distance" interactions between atoms. Considering all of the above then in quantified spacetime we have the amazing possibility that "expansion" can (partially?/fully?) mean that new spacetime atoms pop into existence between existing atoms. How would nearby fundamental particles be influenced by that? That's a mind melter. One of the most difficult things to conceive of in quantified spacetime is a gravity wave. You may be tempted to think a gravity wave is just a waving of spacetime atoms but no, if it was 100% just that, the gravity wave would not be noticeable from within spacetime. Something else waves and one of the most fascinating possibilities is what waves is the rate at which time elapses. I wasted quite some time trying to imagine that. B. Or maybe spacetime is fundamentally continuous (this doesn't mean we don't have the means to probe below a certain length so we assume it's continuous, it means we determine that in our mathematical model of the universe spacetime MUST be continuous or else some other well tested fundamental aspects of our model unravel). Massive questions arise in this case too. Like, literally, what does it even mean to "expand" in this case? If you think about it in depth, expansion makes absolutely no sense here as we have nothing to compare it to. In macroscopic physics, all expansions are like those from (A) if you probe them close enough. Also, with (A) it makes sense to imagine the difference between particles (i.e. stuff that's already "in" our universe) and spacetime (the canvas on which particle live). But with (B) the difference between spacetime and particles becomes very blurry. Particles become more like a local property of spacetime. When the canvas is stretched the particles are stretched, that's a bit easier to ponder, but if you think about where the "new" canvas came from... seems a lot harder than with (A). It's also a lot more difficult to discuss about extra dimensions and non-local interactions with (B). Again it's equally difficult to imagine a gravity wave. Even though particles seem like local properties of spacetime in this case, a gravity wave is clearly distinct from particles and yet it affects them. I can't make sense of that at all. Fun stuff.

Про коды я уже где-то слышала если их знаешь можно свою жизнь перепрограммировать

I’d love this to be explained please: As I understand it (huge caveat right there), expansion of the universe is demonstrated by the red shifting of light from distance objects. This is a similar effect to the Doppler effect on sound as a police siren changes in pitch as it passes by. But, the Doppler effect, in terms of sound waves, does not suggest that the air between the observer and the object is contracting and then expanding. So how do we know that space itself is expanding?

Why are far away galaxies accelerating faster than nearby galaxies?

hurdur diversity fuck off racist

ah, mentioning all that native land bullshit, goodbye

"Ways in which the universe has regular behaviour which we dont understand." This made me think of asteology🤔

Sic itur ad astra. The more we know about the cosmos the more we know and are connected to ourselves and each other. Its all about interconnectedness and greater consciousness. #PhilosophyOfTimeTravel #3767

Katie Mak is so impressive. I definitely intend to explore this series.

What's difference between 🦋 and three Dimensional symbole of infinity!!!

Two words. Lamda CDM. Sorry but for an Atheist, this sounds more like a talk from a Christian Apologist. It doesn't work, at all and you really do need to get a better theory! There's already Quantum Field Theory, perfectly capable of describing all "La Grande Conch's" "discrepancies"... funny but the moment you throw Lamaitre's theory in the bin, suddenly, everything makes sense! en.wikipedia.org/wiki/List_of_largest_cosmic_structures - Add these up, all 100 Billion Galaxies, with their 100 Billion Stars (Each), Planetary formation, Nebulas and the oddities, such as "The Great Attractor", having a mass 100 quadrillion times greater than our sun and span of 500 million light-years, together with the "Zone of Avoidance", which combine creating an immense Gravitational pull on our Galaxy through space at an unprecedented total current speed of 1000 kilometres per second (700,000 kilometres per hour), as Earth orbits the Sun at 107,000 kilometres per hour, as our Milky Way galaxy travels 2,200,000 (2.2 Million) kilometers per hour, relative to the cosmic background radiation, on a one way trip, beyond our currently ability to determine where exactly or what happens when we arrive, somewhere in the general vicinity of the constellation Centaurus...while somehow "accurate" measurements from "Caphid Variable Stars" (variable light sources, to keep things intresting) with the trusty "Type Ia supernovae", possibly balancing things using "RR Lyrae stars", a.k.a Tully-Fisher relation galaxies, seem to completely evade man. Don't you wonder why? Our present-day patch in the Universe, is a result of a multi-billion-year construction effort, with Sagittarius A* excerting 300 times more gravitational force, than previously anticipated, throwing Fred Zwicky's "Darkness", into the light.. I know its convenient and some lovely possibilities and made possible by Lamaitre's "primeval atom theory". However, that it is not how Science works and the Universe, does not owe you an explanation for its being. It clearly makes the smartest men, seem very feeble and fragile, which isn't courage. Its damned foolishness and of no real value continuing to waste time with such a hopeless field of science! Astronomers are not Physicists, not Chemists, Mathmaticians or trained with Quantum Mechanics. Those who are, like Neil right here, surely is aware of what a giant can of flaws he's grappling with. Trying to plug holes in a broken theory, with every greater efforts and costs.. is like plugging holes in the Titanic, using pickles. Find something better to do with your life!

Or - dark matter doesn’t actually exist and we’re just measuring wrong

I dont agree with him in terms of what he is talking about complexity. Still he is one bright mind.

yessssssss

Yes, evolution, changing, and ending. Certainly cornerstones of understanding for the human condition. There is no better quality of silence in nature than cosmological magnitude.

The fundamental phenomenon of dilation explains dark matter/galaxy rotation curves. Mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". A 2 axis graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. A time dilation graph illustrates the same phenomenon, it's not just time that gets dilated. Neil deGrasse Tyson recently spoke about this. Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum. This includes the centers of very high mass stars and the overwhelming majority of galaxy centers. It can be inferred mathematically that the mass at the center of our own galaxy is dilated. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. More precisely, everywhere you point is equally valid. In other words that mass is all around us. Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. It has been confirmed in 6 very low mass galaxies including NGC 1052-DF2 and DF4 to have no dark matter, in other words they have normal rotation rates. All binary stars have normal rotation rates for the same reason.

Doesn't this title sounds silly?

Yay! Let's go!

this is going to be incredible; i can't wait!

Looking forward to this series!

Outstanding! Looking forward to it.

Katie

Katie has a great delivery... I'm in!

Hang out with the Green brothers long enough and you inevitably start a RUclips series 😂 This looks fantastic Dr. Mack! Can't wait to watch.

🫣🤢🤮

I hope I can study at PI someday.

I came for the Cosmology. I left with a better understanding of Special Relativity. ♥^.^

Bill Donahue brought me here

His ASMR is a strong force that binds the universe together.

Is it just a binary condition or simplified model for an infinite set of conditions?

Let the girl get a word in

taken a look at sun lately?

He never mentioned the"Wow" signal.
