Someone help me to understand where these events come from? When you go to the WSF site, and click on "upcoming events", there's nothing, but whenever a video is posted, you go to "upcoming events", and there it is, posted as if someone went back in time and posted it. Are these events things that one can buy tickets to and attend, or do they mystically appear in the past from a parallel universe? Not annoyed, just wondering who all the people are in attendence and how they got there. It would be fun to attend a live event.

The quest to understand cosmic origins is a profound journey into the fundamental questions of existence. By probing the earliest moments of the universe, scientists aim to uncover the conditions that led to the formation of galaxies, stars, and ultimately, life itself. Advances in cosmology, such as observations of the cosmic microwave background and the study of primordial black holes, are helping to piece together the puzzle of how the universe began. As we explore these cosmic origins, we face an intriguing question: How will our discoveries about the early universe influence our understanding of cosmic evolution and our place within this vast, ever-expanding cosmos?

[@joegordon-p6x]

our place within the universe is much much less significant than an ant crawling over an ant hill , ant hill earth

[@melvinpjotr9883]

I liked the down-to-earth approach of Adam Riess, along the lines "lets see where the data lead us". Disappointed about the "discussion" on inflation. I think Adam has it right on inflation - the "evidence" is at best indirect and we have to keep an open mind regarding our current understanding of gravity (and model-building based on that understanding). Inflation seems more like a fix for an imperfect model, that is (quite obviously) very good at describing the universe's current state (in the range z ~ 1000).

[@lindsayforbes7370]

Try this. It could help explain both the S8 snd and Ho tension. We assume that there is only one universe in the cosmos. It's only 100 years since we assumed that there was only one galaxy in the universe. Imagine our universe in a galaxy of universes. The gravitational pull from those masses would become increasingly more significant over time. The value of Ho would increase over time and the rate of structure formation would slow down. No new physics required. The universe has always been bigger than we thought.

[@jonreiser2206]

With regard to the expanding universe theory, couldn’t it be that only the region we can see happens to be expanding? What I mean to say is the universe is unfathomably large. Maybe the visible portion of the universe for which we exist in has been thrown by the great attractor as we spin around the thing. Maybe if there was a way we could zoom out far enough, and somehow map a much much larger portion of the universe, we would find quintillions of strings and webs of galaxies, spinning around some insanely large black hole we call the great attractor. Nature is cyclical after all. It doesn’t seem unreasonable to imagine this idea of mine could be the way things are. Ah, what do I know? I’m just a music teacher.

What is the name of the concluding score and who may have composed the same?

[@ready1fire1aim1]

Zero is the most important number in mathematics and is both a real and an imaginary number with a horizon through it. It's geometric counterpart zero-dimensional space is the most important dimension in physics and is both a real and an imaginary dimension with an event horizon through it. Black holes are ten-dimensional: Zero is the only number with a horizon through it. Zero-dimensional space is the only dimension with an event horizon through it. So, has to include a 0. Got it. 0 and 10 are the first two times we encounter zero in the natural number system (1-9 are nonzero numbers). Their geometric counterparts 0D (quantum) and 10D (cosmological) would then be the event horizon boundaries of this side of the mirror universe.

[@ready1fire1aim1]

[2D is not the center of the universe, 0D is the center of the mirror universe]: The mirror universe theory is based on the concept of parity violation, which was discovered in the 1950s. Parity violation refers to the observation that certain processes in particle physics don't behave the same way when their coordinates are reversed. This discovery led to the idea that there might be a mirror image of our universe where particles and their properties are flipped. In this mirror universe, the fundamental particles that make up matter, such as electrons, protons, and neutrinos, would have their charges reversed. For example, in our universe, electrons have a negative charge, but in the mirror universe, they might have a positive charge. Furthermore, another aspect of the mirror universe theory involves chirality, which refers to the property of particles behaving differently from their mirror images. In our universe, particles have a certain handedness or chirality, but in the mirror universe, this chirality could be reversed. Leibniz or Newton: Quantum mechanics is more compatible with Leibniz's relational view of the universe than Newton's absolute view of the universe. In Newton's absolute view, space and time are absolute and independent entities that exist on their own, independent of the objects and events that take place within them. This view implies that there is a privileged observer who can observe the universe from a neutral and objective perspective. On the other hand, Leibniz's relational view holds that space and time are not absolute, but are instead relational concepts that are defined by the relationships between objects and events in the universe. This view implies that there is no privileged observer and that observations are always made from a particular point of view. Quantum mechanics is more compatible with the relational view because it emphasizes the role of observers and the context of measurement in determining the properties of particles. In quantum mechanics, the properties of particles are not absolute, but are instead defined by their relationships with other particles and the measuring apparatus. This means that observations are always made from a particular point of view and that there is no neutral and objective perspective. Overall, quantum mechanics suggests that the universe is fundamentally relational rather than absolute, and is therefore more compatible with Leibniz's relational view than Newton's absolute view. What are the two kinds of truth according to Leibniz? There are two kinds of truths, those of reasoning and those of fact. Truths of fact are contingent and their opposite is possible. Truths of reasoning are necessary and their opposite is impossible. What is the difference between Newton and Leibniz calculus? Newton's calculus is about functions. Leibniz's calculus is about relations defined by constraints. In Newton's calculus, there is (what would now be called) a limit built into every operation. In Leibniz's calculus, the limit is a separate operation. What are the arguments against Leibniz? Critics of Leibniz argue that the world contains an amount of suffering too great to permit belief in philosophical optimism. The claim that we live in the best of all possible worlds drew scorn most notably from Voltaire, who lampooned it in his comic novella Candide.

The issue with the ether is that it is also a part of us but has multiple properties of resonation that obscure it's variable change at small enough levels with high enough multiple inputs, coupling, turbulence, and fluid mechanics eventualy it phases resonation to curve space so far that anything effected by it is stretched to obscurity which appears as both there and not there (the uncertainty pricple, SCHRODINGER.. the threshold is that to get to see things this variable or thus finite you have to catch up it in curved time. So to curve that small is the same as curving to obscurity.. as we deem lightspeed the fasted mode for human observation, the space that fine takes so long to shrink that far that the light we would need to send thats fast enough to catch up to it has a wavelength that doesn't confine to that space and creates a black hole. A magnifying effect that we see as a laser because lasers are concentrated enough to curve entropic resonation into inverse flow rippling with turbulent vertices with enough energy input concentration to invert into duality and back around inversely to positive gain over systematic orientation

[@LaboriousCretin]

Nice talk. You need mods in your live chat or might want to turn that off if no mods. Religions showing how bad/evil they are. You might want to look at the paper for S8 solution. It might help hubble tension. Mapping neutrinos through dark matter halos will tell things about Wimp or dark sector interactions and neutrinos. Particle production in given energy regimes and gravitational waves needs to be looked at. Energy density in a given space and curvature needs to kind of be gone back over. As far as big bang modeling. Being real below 12.5 light year diamiter it is anyone's guess as long as it fits a few things. Quantum degenerate matter Islands with a shared quantum state or single point foliation/sheafs/particles/strings. Nested shells/sheets with super luminal in a medium propigation or gravitational collapse wave spreading out or sheet punch through and 12.5 light year diamiter flash over or dimensional collapse depositing onto a string brane or Q.M. universe pair production. You get the idea. T=0 and before and shortly after should not be taboo. Let the flood gates open and see if there is a way to test between models. Do the constraints on quantum foam ( smoothness of space ) match up with C.M.B. fluctuations? Has anyone looked into hawking radiation artifacting. Trail, spherical, dotted, ring/s. Or looking at neutrino artifacting. One handed 3 generation broken symmetries in first gen particles that survive. Q.C.D. axioms relicing on C.M.B.. I would like to see a neutrino detector for C.N.B. ( cosmic neutrino background). Neutrino modeling in neutron stars and looking at double shockwaves in super nova modeling. Finish modeling interiors of black holes. The energy density regimes that specific particles can live in. The Q.M. killing fields. Sounds like a game or movie lol. Before T=0 can be theorized. Penrose eaon, String sheets, boltzmann time bombs, primordial collision, even super computing super artificial intelligence inductive testing if structured and formed right lol. The point being it should not be taboo and logical routs explored. Keep up the good work and good luck in wonderland.
