    I was rather surprised when I recently learned that the British science communicator and ex-particle physicist Brian Cox supposedly debunked the Big Bang with a creation story, no less than in a BBC documentary. I had a look at the clip and I think I know what happened.
    The Daily Express article with the BBC clip is here: www.express.co.uk/news/scienc...

    TLDR: A scientist said something salacious and the press ran with it like a Christmas ham under their arm. The more I hear about this type of stuff, the more I think that "separation of press and science" is more important than separation of Church and State.

      I am not a mathematician, but the idea of infinity as well as proportions or types of it, such as half infinity, is all considered kind of a real thing. Even though that's all basically still just infinity.
      First of all you need to fully accept that we humans have no perception of it, and that it's fully natural to emotionally dismiss it.
      The start to see that this way of thinking opens lots of possibilities in science, and especially with physics and time.
      Also think a second about how time can become infinitely slow around black holes, while it still is there.
      There is also something with singularities if I am right. They do not actually exist at our point in time, but the idea is that they exist infinitely far in the future for related reasons, if they actually even do.

    Our understanding of physics is constantly evolving, and it's possible that new discoveries in the future could shed light on what happened before the Big Bang.

    Something I've been thinking of a lot is what if it's not expanding but instead shifting like water. Instead of it having a beginning it just "is" along with all of the stuff within it which tends to gravitate to each other overtime.
    How it behaves now and how we imagine it could've started seems to have a disconnect.
    Galaxies collide with each other often and/or move apart, just constantly moving in different directions like a trash pile in an ocean.
    Gases that also exist in this space gravitate to each other until you get nebulas and the process of creating matter happens on its own.
    It makes much more sense to me that the universe just always was and the process for creating stars had the by-product of creating other materials. Like we know how stars are made and yet we assume it all happened all at once but also took billions of years before looking like what we understand now.
    It would be more consistent if the entire process took billions upon billions of years rather than part of it and then BANG

    I just have a postulation for gravity: It's "symmetry breaking" was in multiple stages. At T- 1x10^-44s till 1x10^-40s , whatever the universe was went 1 dimensional on us, then between 1x10^-40s to 1x10^-36s at a 90°angle, it went 2 dimensional on us, and between 1x10^-36s and 1x10^-32s, also called inflation, it went from an already huge 2 dimensional area at a 90° angle to what we know as spacetime. Each one of those stages has dark energy as a consequence, just like radioactive particles have alpha, beta, x-ray, gamma radiation as a consequence which actually are, helium-4 nuclei or 2 protons and 2 neutrons, called alpha radiation, beta radiation would be electrons and positrons, and both x-ray and gamma radiation is electromagnetic radiation or high energy photons, so I hope you can forgive that I think that symmetry breakings can have consequences like that too, and I think it's dark energy, so bite me :p
    The rapid decay of gravitons, consequences of dark energy, caused photons, neutrinos, gluons that briefly clothed up into glueballs causing pressure and heat together with the photons and neutrinos at a very confined space still, which was hot and dense enough for Grand unified theory to take over from here.
    This means, the bigger a black hole, the colder it's core is going to be. This postulation unlike many theories does have a way to disprove it or ... not and gives us valuable data we didn't have yet?
    Just shoot it to a lagrange point, and trap 'n deform a bose einstein condensate of rubidium, maybe if i'm right it might take longer to reshape into a ball when the magnetic field was dropped and free floating than usual and there is a cold threshold where a critical point was reached?

We are the natural evolution of resonation currents trying to shear the radiation waves they needle cast to phase vibrate through. Just think of the universe as a neutrino ocean and pay attention to fluid mechanics/dynamics.. curvature into spheres is the perfect inverse skirting of resonation pressure attempting to squeeze things into diffraction after loosing their coupling, entanglement, attraction forces/reactions. Because they weave through paradoxical sets in a looped system.. it can only expand to evolve together in Ying yang transference across turbulent exchange into strange attraction. So like the train in the movie "the core" .. no matter how much energy pours in or how much one side jumps to gain relative to the other.. they refraction and bifurcate waves and vertices, Vortex and supernova, fusion and resonation pulsation field coupling to only strengthen eachother.

    PhD Student in Cosmology/Astroparticle Physics here. To my understanding the whole cosmology community understands the "Big Bang Theory" to be the theory about how a very hot and dense state of the very early universe leads to the universe in which we live today. The earliest time "after the singularity" we have any clear knowledge about is at around 3 minutes when the first nuclei were formed (theoretical calculations agree with the observed abundances). This is colloquially known as "Big Band Nucleosynthesis"... note that this is not referring to any singularity, and still contains the words "Big Bang".
    We have no clear evidence what happened before Big Bang Nucleosynthesis, everything is extrapolation from what we know from particle physics and some speculation... Therefore, if inflation would be a correct theory, reheating would indeed initiate the Big Bang, and I would not know any cosmologist heavily arguing against that terminology. Everyone seems to believe that the initial "singularity" cannot be physical, so there is no reason to refer only to this unphysical instance as the Big Bang... it is more about what follows.

      The latest observations suggest that it is likely that the universe will eventually contract.
      Philosophical intuition and logic tells me the same thing as it tells you, but experimental evidence is needed.
      What is expected is that the dimensions can only be those that we observe since they are an abstraction of the orthogonal directions from a point, from that reasoning and knowing that nothing can arise from absolute nothing, what can be deduced is that space-time has always existed and will always exist, with local Big Bounce cycles probably.
      I am of the opinion that what we call the Big Bang can be described as a white hole and what we call the Big Crunch can be described as the maximum density black hole that is incapable of further curving space and undergoes a transition towards a new white hole, or Big Bang.

    Well, part of the problem is that 'Big Bang' is a terrible name. At best, it was a super tiny event and there was no 'bang' because there is no air in space. Also, the theory doesn’t adequately explain certain aspects. Why 'Big'? How did the 'Bang' happen? It's like naming a theory 'apple theorem' and then discussing orange juice. Moreover, what kind of theory requires adding 95% of unknown substances to make it work? That's a 20-fold error. It's akin to a child claiming to have two PHDs after the first year of school (the additional 19 being 'dark education'). So, rightfully, people question if the theory's name is wrong, what else could be? If you need to add (fake it to make it ) 95% material to fit observations, it's not science; it's prophecy.That's exactly it. This is precisely why a Priest read the Bible and formulated the Big Bang theory. Just like other observations, such as everything appearing to orbit around us, leading to the belief that we are at the center of the universe.. It's astonishing that people still refer to observations as facts, much like those who claim the Earth is flat because, based on limited observations, the horizon appears flat. The Big Bang theorists are, at best, like divorce scientists who conclude the main reason for divorce is marriage based on observations alone. Without mathematics, it's not science; it's philosophical speculation. Mathematics clearly shows that 5 does not equal 100, and it's time to abandon such religious-like beliefs and seek better theories.

    I dropped out of engineering college in my second year after losing a grant due to a delay in getting tax documents from my parents and a car accident. Kids kept me at work full time not to return to school. I’m a CNC programmer now; make lots of surgical and aerospace components. My new dream is to start my own company and partner with people in the medical industry to provide more affordable surgeries to those in need through efficient manufacturing and, hopefully, hospitals and doctors willing to work with us.

    I think the two most current theories of which I'm aware are by Laura Mersini-Houghton (author of Before The Big Bang: The Origin of the Universe and What Lies Beyond, July 2022), who proposes that our universe is part of a multiverse created when the cosmic wave function resolved at different energy points across a string theory "landscape" - and the other by Thomas Hertog and Stephen Hawking (author of On The Origin of Time, 2023) which proposes that the universe resolved from a quantum state due to our observing it backwards in time (given that by Einstein's equations the arrow of time is bidirectional). At least, I think I understand these two theories that way. Each has given a presentation on their theory at the Royal Institute as well (one can find the videos on CZcams). I would be very interested in Sabine's take on both of them.

    • @juanausensi499
      @juanausensi499 Před 2 měsíci +1

      I'n not Sabine, but i can answer that. The answer is yes. There is a limit on how far away we can see, because the speed of expansion becomes faster than the speed of light after a certain point. That's not in contradiction with general relativity because nothing (i.e., matter and energy) is moving faster than the speed of light in their own frames of reference. The set of all things we can see is called the observable universe: it's a sphere of 45.7 billion light-years radius centered on us (of course, if there are alien astronomers in another place of the universe, their observable universe would be also centered on them)

    A cycle of Big Bang to Big Crunch to Big Bang, and so on, makes the most practical sense. The problem is that it not only makes a start point possibly impossible to find but it also makes a start point redundant. Just like when someone asks "where do we go when we die" and someone answers "the same place you were before you were born." People just don't like the most obvious answers.

  • @kunibald128
    @kunibald128 Před 3 měsíci +5

    Sabine, I have not understood why you say that eternal inflation must also have had a beginning at some finite time in the past. My understanding of this theory is quite limited, but what I get is that it should, on large scales (much larger than any individual universes), more or less resemble a de Sitter model (spatially flat with Omega_Lambda = 1). Under these conditions the expansion law is a pure and simple exponential, it does not admit any beginning or singularity and more in general there is nothing special about any point in time.

  • @DrEnzyme

    I've always liked the comparison of "asking what was before the big bang is like asking what's north of the north pole." It might not be right if there's all these theories out there about what came before, but I think it gets you in the right mindset to think about time and space as intrinsically connected. There's all sorts of interesting questions that come out of it, like how do you build a frame of reference that doesn't consist of space or time? What is the universe expanding into? Does that question even make sense? Mind boggling stuff to think about and it's kind of amazing that us pink meat apes can even begin to think about it.

      That’s because we are not just “pink meat apes” that just stumbled on fire and electricity by accident, our consciousness is also not generated by our brains rather a receiver, that’s why we can even ask such questions. I doubt that “animated matter” with chemical reactions(which is what we are portrayed as being) can think such mind melting topics especially when this gets mixed with theology( btw theology and science are both asking the same questions just in a different was like 2 different sides of the same coin)

If there's a higher dimension then where did that come from? How can it contract if it doesn't also have some dimension that represents time or space?
      It's mind boggling, the more I think about it the less sense it makes. Clearly "Something Happened," and we're all here today, but the idea of "Something Happening" without time or space existing doesn't make any sense, let alone "everything happening all at once."

    Incalculable mass to incalculable volume is not infinite - it is undeterminable.
