[@dennisjahnke7455]

I started reading and listening to physics and cosmology lectures about 10 years ago and I didn't understand most of what I read, but what I did understand was intriguing. Don't give up, the more you listen the more you will understand. I'm at a point in time now where I'm really interested in finding more about the mathematics. After all science is about seeking what we don't know . And you know the old saying, the one thing I know for sure is that I don't know

[@vincentzimmerman2011]

I applaud your honesty and wonder for the universe. The good thing about science is that you don't need a background in mathematics or science to learn more about the universe. There's no end to the books and programs(online or not)that approach science from a beginner's level. I would learn more about science if I could do mathematics, but unfortunately, I have no ability or aptitude for math. I'm grateful for programs like this one, they make science accessible for people like me. I think you're right, people like Brian Greene don't look down on us for our ignorance, they probably would have a pint with you if they had the opportunity.

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?

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.

[@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).

Fluid mechanics is a great way to think about it. Space is a variable neutrino ocean. Vacuum is an effect comes from multiple dynamics. Things such as QCD and the coupling along with effects through a resonating variable field that each change eacother with variation, inverse in nature, but universal under properties. Adding in things like chaos theory, refractional vertices making with fluid like mechanics and dynamics of influence such as the von Karman Vortex streets... ultimately with enough coupling reordering phasing curvature and inverse inputs that at a high enough phase efficiency that space curves enough to invert flow energy in the reaction. We need to understand our own phasing evolution with spacetime, both it outside of us yet phasing in parallels smaller than the Planck length. So things like resonation whips apply, yet as you look from a far enough point you can view refraction patterns and detect wave pressure energy. Either we are the edge of this evolving constant that looks like waves through time and particles at the edge where quantum tunneling properties lead evolution, yet a closed system under repeating values that show patterns in matter and energy. If we aren't the particular point of the "current" ..right now, the present, connected instantaneous with past evolution through refractional reverberations but are the evolving invading phasing pulsating points of multiple resonation rippling coupling sets that have evolved to curve space enough for us to continuely phase through it, but we are actually phasing ourselves as wave partical duality that has evolved to resonating with enough finite energy they appear to be points our elementary particles and the oscillations inbetween with pressure refractional duality

I dont think Supersymmetry exist in our universe, but they could exist in another parallel universe next to ours, that could explain the dark matter that gravitationally interacts with matter in our universe but were not able to detect with current instruments due to the supersymmetric particles acting as the dark matter in our universe while they exist in extra dimensions or a parallel universe right next to our Universe.

[@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.

Spectacular and enriching!!! Dark energy & DM constantly puts everything into perspective as we are receding rapidly away from our cosmic origins/point of creation towards the end of time as space is expanding 😅 while keeping in mind and taking into consideration that observation is key for the deeply hidden realm 😏😅 Looking at the big picture now to gain more insight on our frame of reference starting at the Big Bang and ultimately towards the utmost boundary of our cosmic horizon (end of time). Bound to an eternal cyclical universe we could potentially slip or bounce into another Big Bang probably without noticing or even feeling it 😅 Indeed dark matter and dark energy enhances our common sense and intuition 😅

[@rezadaneshi]

Is it possible Traveling in a universe that is spinning in its expansion making every photon take a curved path while waving, to become our default setting for the shortest path, and since we have to collapse it to observe it, we assuming a “straight” path; then when we add the stand alone gravitational lensing amplified by that universal curvature, could it be why it’s appearing as if we need more mass for that outcome?

[@CanadianRefugee]

Love watching these bit high! At a plank scale, quantized space would be horizon like, and a field could have a Casimir like effect pushing those quanta apart. Akin to a single quark not being possible, the new quanta of space arises from that energy, and so on...

The microbes most likely aren’t the only forms of extraterrestrial life somewhere out there and in all actuality it’s only a matter of time until a point in space exploration opens up something truly beneficial to humanity, maybe not soon or maybe not later but scientific possibilities are paramount to a self aware, sentient understanding.

How do they distinguish the difference between that radiation and the big bang radiation?

I imagine that it is because the measurements and photo's of the background radiation are always taken Outside the Earth's atmosphere.

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.

[@ricardosaldanha6662]

Dear Axle.student, don't be too impressed by the scientific eloquence of the personalities. In the field of speculation they point to theories and nothing more, many of them that swarmed people's brains for decades and literally fell apart, leaving a void, the case of the Big Bang Theory, a tremendous nonsense of 13.7 ( ?) millions of years, as can be seen by observing where the James Webb telescope points. Space and Time are not considered physical entities, strictly speaking, they come from the fact that they are conceptually and purely mathematical entities, (from Classical Geometry to the many abstract mathematical and geometric locubrations and daydreams) because metrically they are of the same caliber, in fact Time it is considered a spatial dimension of order -1 or complex, if it is required to work that way or whatever you want to call it, evidencing Theories of Conformal Spaces, Poincaré group, Clifford Algebra, Conformal Lie Algebra, etc. Start by imagining identifying an open box propagated in all directions with straight lines like Laser light and without limits, where you have placed an appreciable amount of spaghetti, chaotically curved or curled, together occupied by appreciable amounts of conveniently crumpled and intertwined cellophane subject to perforations between each other as if pitcher plant flowers were sprouting from each other or like cabbages. There you have a slightly hilarious idea of ​​Space-Time already occupied, wrinkled/curved by the action of the Matter-Energy/Dark Matter fields of the gravitic interaction between this Existing Matter and Energy. Now take into account the other fundamental forces known so far and imagine the entanglement that could result in successive, functionally or logarithmically smaller scales. The notion of observable, Quantum Gravity,...Spaces or Holographic Universes was left out. Pay attention to your second question, it is worth making the distinction between the cosmological microwave background radiation that is observed in the observable Universe and the local radiation, say a few parsecs of fourth dimension or in a Minkowski space, if you want to call it where condensed matter is scarce (stars, planets, dust).

Scientists and cosmologists have discovered that the most distant galaxies are receding from view at a rate faster than those galaxies closest to us. They made this determination by observing the red shifted light from the distant galaxies and applying the Doppler effect. So they conclude that the galaxies 13.8 billion light years away are moving away from us much faster than those that are only say 1 billion light years away. But are they neglecting time? If we see red shifted light that left a galaxy 13.8 billion years ago compared to light from closer galaxies that is not red shifted, aren’t we observing what happened in the distant past compared to the much more recent past? Wouldn’t the expansion of the universe actually be slowing down, not speeding up? The faster galaxies are much older than the newer, slower galaxies. The fast moving galaxies were receding at the highest speed 13.8 billion years ago. Doesn‘t this actually indicate that the expansion of the universe is slowing down?

[@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.
