    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...

      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.

    I asked GOOGLE's Bard, and here's what it said: The concept of "before" the Big Bang might not even be meaningful in the traditional sense. Time itself is thought to have begun with the Big Bang, so talking about what happened "before" is like trying to describe what's north of the North Pole.
    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.
    So, while we may not have a definitive answer to your question yet, the quest to understand the origins of the universe is one of the most fascinating and challenging in all of science. And who knows, maybe someday we will be able to crack this cosmic mystery!

      Some questions have inherent assumptions built into them. Examples of such questions that are NOT meaningless include leading and loaded questions. Other times, the bult-in assumption simply makes no sense. "How many angles can fit on the head of a pin?" depends on if an angel occupies a finite amount of physical space and, if so, how large a head of a pin really is in comparison (do we take a statistical average all pins in the world?)

      It's the natural curve evolution to shear entropic radiation resonation waves. We know literally everything in the universe has it's paradoxical opposition. The fact that we can make any choice or have distinction between inverse properties.. entropy wants our disorder to permeate and refract into nitrogen jello or plasma without thermodynamics.. but we are here, partially aware of this, evolving everything scope to human existence towards curving our destruction. 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.

      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)

    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.

      But as it is now parts of the universe we can observe is moving away from us and is already moving away faster then light speed can cover the distance and it is lost for us forever (that is called the particle horizon).

      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.

    Catholic priest and theoretical physicist George Lemaitre is the father of the big bang theory and for this concept he let himself guide by the Genesis: Let there be light and there was light. For him the suddenness of the light‘s existence was equal to the suddenness of matter coming into existence.

    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.

    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.

  • @njhoepner

    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 TH-cam). I would be very interested in Sabine's take on both of them.

    @countcampula 2 หลายเดือนก่อน +1

    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
